短信登录作为一种常见的登录认证方式，在
Spring Security中是没有的，本篇博客将继续在之前文章的基础上，建立一套短信登录验证机制，并将其集成到Spring Security中。
一、短信登录验证机制原理分析
在Spring Security中，我们最常用的登录验证机制是基于用户名和密码的，输入了用户名和密码以及图片验证码之后，就会进入一系列的过滤器链中，直到验证成功或者验证失败为止。结合下面的图，我们来简要分析一下Spring Security是如何验证基于用户名和密码登录方式的，分析完毕之后，再一起思考如何将短信登录验证方式集成到Spring Security中。
基于用户名和密码的认证流程分析
- 第一步：在登录页面输入了用户名、密码和图片验证码，点击登录，那么这个登录请求首先被图片验证码的验证过滤器
ValidateCodeFilter拦截，因为我们在BrowserSecurityConfig类中将拦截器ValidateCodeFilter配置到了UsernamePasswordAuthenticationFilter之前，如果验证码验证通过之后，请求将继续被UsernamePasswordAuthenticationFilter拦截，进入到它的attemptAuthentication方法中进行校验，该方法首先对请求方法进行了校验，默认是POST方法，然后从请求中获取用户名和密码，并基于用户名和密码生成了UsernamePasswordAuthenticationToken，并在生成Token的过程中将是否认证通过设置为false。 - 第二步：
UsernamePasswordAuthenticationFilter的attemptAuthentication方法继续调用AuthenticationManager的authenticate方法进行验证，在真正验证之前，验证器会从集合循环遍历AuthenticationProvider，使用AuthenticationProvider中的supports方法来判断当前传递过来的Token到底应该由哪个AuthenticationProvider来进行校验，UsernamePasswordAuthenticationToken将由DaoAuthenticationProvider来进行校验，通过调用UserDetailService的loadUserByUsername方法来完成验证，最后结合验证结果，重新构建UsernamePasswordAuthenticationToken，并将Token中是否认证通过设置为true完成认证步骤。
基于短信的认证流程分析
分析完基于用户名和密码的认证流程之后，我们可以将整个流程应用到需要我们自己定义短信认证的流程中，也就是说，短信认证的流程完全可以参考基于用户名和密码的认证流程，那么我们的短信认证过程也需要有相应的SmsAuthenticationToken、SmsAuthenticationFilter、SmsAuthenticationProvider以及验证短信验证码的SmsCodeFilter。
- 第一步：类似于图片验证码的校验，
SmsCodeFilter也需要加到SmsAuthenticationFilter之前，在短信验证码验证通过之后，那么登录请求到达SmsAuthenticationFilter，进入到它的attemptAuthentication方法中进行校验，该方法首先对请求方法进行了校验，默认是POST方法，然后从请求中获取到手机号码，并基于手机号码来生成SmsAuthenticationToken，并在生成Token的过程中将是否认证通过设置为false。 - 第二步：
SmsAuthenticationFilter的attemptAuthentication方法继续调用AuthenticationManager的authenticate方法进行验证，在真正验证之前，验证器会从集合循环遍历AuthenticationProvider，使用AuthenticationProvider中的supports方法来判断当前传递过来的Token到底应该由哪个AuthenticationProvider来进行校验，SmsAuthenticationToken将由SmsAuthenticationProvider来进行校验，通过调用UserDetailService的loadUserByUsername方法来完成验证，最后结合验证结果，重新构建UsernamePasswordAuthenticationToken，并将Token中是否认证通过设置为true完成认证步骤。
分析的过程和基于用户名和密码的方式是一模一样的，那么我们该如何来写这四个类的代码呢？我们当然是要参考对应的代码了！首先我们先一起写SmsAuthenticationToken的代码，那么我们来参考一下UsernamePasswordAuthenticationToken的代码，直接将其拷贝过来进行简要修改。
package com.lemon.security.core.authentication.mobile;
import org.springframework.security.authentication.AbstractAuthenticationToken;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.SpringSecurityCoreVersion;
import java.util.Collection;
/**
* 使用短信验证码登录的Token，写法类似{@link UsernamePasswordAuthenticationToken}
*
* @author lemon
* @date 2018/5/7 下午8:38
*/
public class SmsCodeAuthenticationToken extends AbstractAuthenticationToken {
private static final long serialVersionUID = SpringSecurityCoreVersion.SERIAL_VERSION_UID;
// ~ Instance fields
// ================================================================================================
private final Object principal;
// ~ Constructors
// ===================================================================================================
/**
* This constructor can be safely used by any code that wishes to create a
* <code>SmsCodeAuthenticationToken</code>, as the {@link #isAuthenticated()}
* will return <code>false</code>.
*
* @param mobile 手机号
*/
public SmsCodeAuthenticationToken(String mobile) {
super(null);
this.principal = mobile;
setAuthenticated(false);
}
/**
* This constructor should only be used by <code>AuthenticationManager</code> or
* <code>AuthenticationProvider</code> implementations that are satisfied with
* producing a trusted (i.e. {@link #isAuthenticated()} = <code>true</code>)
* authentication token.
*
* @param principal 认证信息
* @param authorities 权限列表
*/
public SmsCodeAuthenticationToken(Object principal, Collection<? extends GrantedAuthority> authorities) {
super(authorities);
this.principal = principal;
// must use super, as we override
super.setAuthenticated(true);
}
// ~ Methods
// ========================================================================================================
@Override
public Object getCredentials() {
return null;
}
@Override
public Object getPrincipal() {
return this.principal;
}
@Override
public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
if (isAuthenticated) {
throw new IllegalArgumentException(
"Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
}
super.setAuthenticated(false);
}
@Override
public void eraseCredentials() {
super.eraseCredentials();
}
}
第一个构造方法用于在短信认证前使用，将手机号码传入到构造方法中，并将Authenticated设置为false，第二个构造方法用在认证成功之后，重新构造Token的时候，将手机号和权限列表传入到其中，并设置Authenticated为true。
我们继续编写SmsAuthenticationFilter的代码，当然，也是得参考UsernamePasswordAuthenticationFilter，代码如下所示。
package com.lemon.security.core.authentication.mobile;
import org.springframework.security.authentication.AuthenticationServiceException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;
import org.springframework.util.Assert;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* @author lemon
* @date 2018/5/7 下午8:54
*/
public class SmsCodeAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
// ~ Static fields/initializers
// =====================================================================================
private static final String SPRING_SECURITY_FORM_MOBILE_KEY = "mobile";
private static final String SPRING_SECURITY_FORM_SUBMIT_METHOD = "POST";
private String mobileParameter = SPRING_SECURITY_FORM_MOBILE_KEY;
private boolean postOnly = true;
// ~ Constructors
// ===================================================================================================
public SmsCodeAuthenticationFilter() {
super(new AntPathRequestMatcher("/authentication/mobile", "POST"));
}
// ~ Methods
// ========================================================================================================
@Override
public Authentication attemptAuthentication(HttpServletRequest request,
HttpServletResponse response) throws AuthenticationException {
if (postOnly && !SPRING_SECURITY_FORM_SUBMIT_METHOD.equals(request.getMethod())) {
throw new AuthenticationServiceException(
"Authentication method not supported: " + request.getMethod());
}
String mobile = obtainMobile(request);
if (mobile == null) {
mobile = "";
}
mobile = mobile.trim();
SmsCodeAuthenticationToken authRequest = new SmsCodeAuthenticationToken(mobile);
// Allow subclasses to set the "details" property
setDetails(request, authRequest);
return this.getAuthenticationManager().authenticate(authRequest);
}
/**
* 从请求中获取手机号的方法
*
* @param request 请求
* @return 手机号
*/
protected String obtainMobile(HttpServletRequest request) {
return request.getParameter(mobileParameter);
}
/**
* Provided so that subclasses may configure what is put into the authentication
* request's details property.
*
* @param request that an authentication request is being created for
* @param authRequest the authentication request object that should have its details
* set
*/
protected void setDetails(HttpServletRequest request,
SmsCodeAuthenticationToken authRequest) {
authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
}
/**
* Sets the parameter name which will be used to obtain the mobile from the login
* request.
*
* @param mobileParameter the parameter name. Defaults to "mobile".
*/
public void setMobileParameter(String mobileParameter) {
Assert.hasText(mobileParameter, "Mobile parameter must not be empty or null");
this.mobileParameter = mobileParameter;
}
/**
* Defines whether only HTTP POST requests will be allowed by this filter. If set to
* true, and an authentication request is received which is not a POST request, an
* exception will be raised immediately and authentication will not be attempted. The
* <tt>unsuccessfulAuthentication()</tt> method will be called as if handling a failed
* authentication.
* <p>
* Defaults to <tt>true</tt> but may be overridden by subclasses.
*/
public void setPostOnly(boolean postOnly) {
this.postOnly = postOnly;
}
public final String getMobileParameter() {
return mobileParameter;
}
}
写完SmsCodeAuthenticationFilter，我们继续编写SmsCodeAuthenticationProvider，那么这个Provider也可以继续模仿DaoAuthenticationProvider来进行编写，也可以自己实现一套校验逻辑，主要是调用UserDetailService的loadUserByUsername方法来进行校验，只是要注意的是，校验完毕后，需要重新构建SmsCodeAuthenticationToken，将权限列表传入到SmsCodeAuthenticationToken中，也就是使用SmsCodeAuthenticationToken的第二个构造方法，构造方法中将Authenticated设置成为true，最后设置用户信息细节，并返回该认证后的Token，代码如下：
package com.lemon.security.core.authentication.mobile;
import lombok.Data;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.InternalAuthenticationServiceException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
/**
* 短信登录的校验逻辑类
*
* @author lemon
* @date 2018/5/7 下午9:16
*/
@Data
public class SmsCodeAuthenticationProvider implements AuthenticationProvider {
private UserDetailsService userDetailsService;
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
// 将Authentication的对象强转为SmsCodeAuthenticationToken对象
SmsCodeAuthenticationToken authenticationToken = (SmsCodeAuthenticationToken) authentication;
// 根据手机号载入用户信息
UserDetails user = userDetailsService.loadUserByUsername((String) authenticationToken.getPrincipal());
if (user == null) {
throw new InternalAuthenticationServiceException("用户信息不存在");
}
// 将获取到的用户信息封装到SmsCodeAuthenticationToken第二个构造方法中，在这个方法中设置为"已认证"
SmsCodeAuthenticationToken authenticationResult = new SmsCodeAuthenticationToken(user, user.getAuthorities());
// 将用户的细节信息封装到已认证的token中
authenticationResult.setDetails(authenticationToken.getDetails());
return authenticationResult;
}
@Override
public boolean supports(Class<?> authentication) {
return SmsCodeAuthenticationToken.class.isAssignableFrom(authentication);
}
}
前面三个主要的类代码写完后，我们继续写一个校验短信验证码的类SmsCodeFilter，代码如下：
package com.lemon.security.core.validate.code;
import com.lemon.security.core.properties.SecurityProperties;
import com.lemon.security.core.validate.code.sms.SmsCode;
import lombok.Data;
import lombok.EqualsAndHashCode;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.social.connect.web.HttpSessionSessionStrategy;
import org.springframework.social.connect.web.SessionStrategy;
import org.springframework.util.AntPathMatcher;
import org.springframework.web.bind.ServletRequestBindingException;
import org.springframework.web.bind.ServletRequestUtils;
import org.springframework.web.context.request.ServletWebRequest;
import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;
/**
* @author lemon
* @date 2018/4/6 下午8:23
*/
@EqualsAndHashCode(callSuper = true)
@Data
public class SmsCodeFilter extends OncePerRequestFilter implements InitializingBean {
private static final String SUBMIT_FORM_DATA_PATH = "/authentication/mobile";
private static final String SMS_SESSION_KEY = ValidateCodeProcessor.SESSION_KEY_PREFIX + "SMS";
private AuthenticationFailureHandler authenticationFailureHandler;
private SessionStrategy sessionStrategy = new HttpSessionSessionStrategy();
private Set<String> urls = new HashSet<>();
private SecurityProperties securityProperties;
private final AntPathMatcher antPathMatcher = new AntPathMatcher();
@Override
public void afterPropertiesSet() throws ServletException {
super.afterPropertiesSet();
String[] configUrls = StringUtils.splitByWholeSeparatorPreserveAllTokens(securityProperties.getCode().getSms().getUrl(), ",");
urls.addAll(Arrays.asList(configUrls));
// 登录的链接是必须要进行验证码验证的
urls.add(SUBMIT_FORM_DATA_PATH);
}
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
boolean action = false;
for (String url : urls) {
// 如果实际访问的URL可以与用户在YML配置文件中配置的相同，那么就进行验证码校验
if (antPathMatcher.match(url, request.getRequestURI())) {
action = true;
}
}
if (action) {
try {
validate(new ServletWebRequest(request));
} catch (ValidateCodeException e) {
authenticationFailureHandler.onAuthenticationFailure(request, response, e);
return;
}
}
filterChain.doFilter(request, response);
}
/**
* 验证码校验逻辑
*
* @param request 请求
* @throws ServletRequestBindingException 请求异常
*/
private void validate(ServletWebRequest request) throws ServletRequestBindingException {
// 从session中获取短信验证码
SmsCode smsCodeInSession = (SmsCode) sessionStrategy.getAttribute(request, SMS_SESSION_KEY);
// 从请求中获取用户填写的验证码
String smsCodeInRequest = ServletRequestUtils.getStringParameter(request.getRequest(), "smsCode");
if (StringUtils.isBlank(smsCodeInRequest)) {
throw new ValidateCodeException("验证码不能为空");
}
if (null == smsCodeInSession) {
throw new ValidateCodeException("验证码不存在");
}
if (smsCodeInSession.isExpired()) {
sessionStrategy.removeAttribute(request, SMS_SESSION_KEY);
throw new ValidateCodeException("验证码已过期");
}
if (!StringUtils.equalsIgnoreCase(smsCodeInRequest, smsCodeInSession.getCode())) {
throw new ValidateCodeException("验证码不匹配");
}
// 验证成功，删除session中的验证码
sessionStrategy.removeAttribute(request, SMS_SESSION_KEY);
}
}
我们将这四个类写好了，那么如何按照上面图片显示的那样，将其纳入到Spring Security的管理之中呢，我们在第二小节下分析。
二、将短信登录验证机制集成到Spring Security中
我们需要将各个组件集成到Spring Security中，那么就需要有一个配置类来完成配置，我们来编写一个SmsCodeAuthenticationSecurityConfig类，将这几个组件集成到一起，代码如下：
package com.lemon.security.core.authentication.mobile;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.SecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.DefaultSecurityFilterChain;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import org.springframework.stereotype.Component;
/**
* 短信验证的配置类
*
* @author jiangpingping
* @date 2019-01-31 22:17
*/
@Component("smsCodeAuthenticationSecurityConfig")
public class SmsCodeAuthenticationSecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
private final AuthenticationSuccessHandler lemonAuthenticationSuccessHandler;
private final AuthenticationFailureHandler lemonAuthenticationFailureHandler;
private final UserDetailsService userDetailsService;
@Autowired
public SmsCodeAuthenticationSecurityConfig(AuthenticationSuccessHandler lemonAuthenticationSuccessHandler,
AuthenticationFailureHandler lemonAuthenticationFailureHandler,
UserDetailsService userDetailsService) {
this.lemonAuthenticationSuccessHandler = lemonAuthenticationSuccessHandler;
this.lemonAuthenticationFailureHandler = lemonAuthenticationFailureHandler;
this.userDetailsService = userDetailsService;
}
@Override
public void configure(HttpSecurity http) throws Exception {
// 首先配置Sms验证的过滤器，在其中配置AuthenticationManager，验证成功处理器、失败处理器和认证的Provider等信息
SmsCodeAuthenticationFilter smsCodeAuthenticationFilter = new SmsCodeAuthenticationFilter();
smsCodeAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
smsCodeAuthenticationFilter.setAuthenticationSuccessHandler(lemonAuthenticationSuccessHandler);
smsCodeAuthenticationFilter.setAuthenticationFailureHandler(lemonAuthenticationFailureHandler);
SmsCodeAuthenticationProvider smsCodeAuthenticationProvider = new SmsCodeAuthenticationProvider();
smsCodeAuthenticationProvider.setUserDetailsService(userDetailsService);
// 将Provider注册到Spring Security中，将Filter加到UsernamePasswordAuthenticationFilter后面
http.authenticationProvider(smsCodeAuthenticationProvider)
.addFilterAfter(smsCodeAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
}
}
在上面的配置方法configure中，我们首先创建一个SmsCodeAuthenticationFilter实例对象，然后设置了一个通用的AuthenticationManager，还设置了验证成功处理器和失败处理器，然后又创建了一个SmsCodeAuthenticationProvider实例对象，并将UserDetailService实现类对象设置到了其中，并将SmsCodeAuthenticationFilter过滤器加到了UsernamePasswordAuthenticationFilter的后面。这样做还是不够的，我们还需要在类BrowserSecurityConfig中加入一下代码：
@Autowired
private SmsCodeAuthenticationSecurityConfig smsCodeAuthenticationSecurityConfig;
SmsCodeFilter smsCodeFilter = new SmsCodeFilter();
smsCodeFilter.setAuthenticationFailureHandler(lemonAuthenticationFailureHandler);
smsCodeFilter.setSecurityProperties(securityProperties);
smsCodeFilter.afterPropertiesSet();
http.addFilterBefore(smsCodeFilter, UsernamePasswordAuthenticationFilter.class);
http.apply(smsCodeAuthenticationSecurityConfig);
完整的配置如下所示：
package com.lemon.security.browser;
import com.lemon.security.core.authentication.mobile.SmsCodeAuthenticationSecurityConfig;
import com.lemon.security.core.properties.SecurityProperties;
import com.lemon.security.core.validate.code.SmsCodeFilter;
import com.lemon.security.core.validate.code.ValidateCodeFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;
import javax.sql.DataSource;
/**
* 浏览器安全验证的配置类
*
* @author lemon
* @date 2018/4/3 下午7:35
*/
@Configuration
public class BrowserSecurityConfig extends WebSecurityConfigurerAdapter {
private final SecurityProperties securityProperties;
private final AuthenticationSuccessHandler lemonAuthenticationSuccessHandler;
private final AuthenticationFailureHandler lemonAuthenticationFailureHandler;
private final DataSource dataSource;
@Autowired
public BrowserSecurityConfig(SecurityProperties securityProperties, AuthenticationSuccessHandler lemonAuthenticationSuccessHandler, AuthenticationFailureHandler lemonAuthenticationFailureHandler, DataSource dataSource) {
this.securityProperties = securityProperties;
this.lemonAuthenticationSuccessHandler = lemonAuthenticationSuccessHandler;
this.lemonAuthenticationFailureHandler = lemonAuthenticationFailureHandler;
this.dataSource = dataSource;
}
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private SmsCodeAuthenticationSecurityConfig smsCodeAuthenticationSecurityConfig;
/**
* 配置了这个Bean以后，从前端传递过来的密码将被加密
*
* @return PasswordEncoder实现类对象
*/
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public PersistentTokenRepository tokenRepository() {
JdbcTokenRepositoryImpl tokenRepository = new JdbcTokenRepositoryImpl();
tokenRepository.setDataSource(dataSource);
return tokenRepository;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
ValidateCodeFilter validateCodeFilter = new ValidateCodeFilter();
validateCodeFilter.setAuthenticationFailureHandler(lemonAuthenticationFailureHandler);
validateCodeFilter.setSecurityProperties(securityProperties);
validateCodeFilter.afterPropertiesSet();
SmsCodeFilter smsCodeFilter = new SmsCodeFilter();
smsCodeFilter.setAuthenticationFailureHandler(lemonAuthenticationFailureHandler);
smsCodeFilter.setSecurityProperties(securityProperties);
smsCodeFilter.afterPropertiesSet();
http.addFilterBefore(smsCodeFilter, UsernamePasswordAuthenticationFilter.class)
.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)
.formLogin()
.loginPage("/authentication/require")
.loginProcessingUrl("/authentication/form")
.successHandler(lemonAuthenticationSuccessHandler)
.failureHandler(lemonAuthenticationFailureHandler)
.and()
.rememberMe()
.tokenRepository(tokenRepository())
.tokenValiditySeconds(securityProperties.getBrowser().getRememberMeSeconds())
.userDetailsService(userDetailsService)
.and()
.authorizeRequests()
.antMatchers("/authentication/require", securityProperties.getBrowser().getLoginPage(), "/code/*").permitAll()
.anyRequest()
.authenticated()
.and()
.csrf().disable()
.apply(smsCodeAuthenticationSecurityConfig);
}
}
直到这里，我们算是完成短信验证码的登录方式，并将其集成到了Spring Security中，我们访问项目的默认登录页面http://localhost:8080/login.html，就可以使用用户名或者手机进行登录，更多详细代码可以从码云中下载查看。大家有什么疑问可以在下方进行留言，我会一一回复。
