基于springsecurity整合springboot实现简单认证授权进行修改实现分布式认证，即我们常说的单点登录，简称SSO，指的是在多应用系统的项目中，用户只需要登录一次，就可以访问所有互相信任的应用系统。
1. 单点登录
总结一下，单点登录的实现分两大环节：
用户认证：这一环节主要是用户向认证服务器发起认证请求，认证服务器给用户返回一个成功的令牌token，
主要在认证服务器中完成，即图中的A系统，注意A系统只能有一个。
身份校验：这一环节是用户携带token去访问其他服务器时，在其他服务器中要对token的真伪进行检验，主
要在资源服务器中完成，即图中的B系统，这里B系统可以有很多个。
2. jwt和rsa
1. JWT 介绍
从分布式认证流程中，我们不难发现，这中间起最关键作用的就是token，token的安全与否，直接关系到系统的健壮性，这里我们选择使用JWT来实现token的生成和校验。
JWT，全称JSON Web Token，官网地址https://jwt.io ，是一款出色的分布式身份校验方案。可以生成token，也可以解析检验token。
JWT生成的token由三部分组成：
头部：主要设置一些规范信息，签名部分的编码格式就在头部中声明。
载荷：
token中存放有效信息的部分，比如用户名，用户角色，过期时间等，但是不要放密码，会泄露！签名：将头部与载荷分别采用
base64编码后，用“.”相连，再加入盐，最后使用头部声明的编码类型进行编码，就得到了签名。
JWT生成token的安全性分析
从JWT生成的token组成上来看，要想避免token被伪造，主要就得看签名部分了，而签名部分又有三部分组成，其中头部和载荷的base64编码，几乎是透明的，毫无安全性可言，那么最终守护token安全的重担就落在了加入的盐上面了！
试想：如果生成token所用的盐与解析token时加入的盐是一样的。岂不是类似于中国人民银行把人民币防伪技术公开了？大家可以用这个盐来解析token，就能用来伪造token。
这时，我们就需要对盐采用非对称加密的方式进行加密，以达到生成token与校验token方所用的盐不一致的安全效果！
2. 非对称加密 RSA介绍
- 基本原理：同时生成两把密钥：私钥和公钥，私钥隐秘保存，公钥可以下发给信任客户端
- 私钥加密，持有私钥或公钥才可以解密
- 公钥加密，持有私钥才可解密
- 优点：安全，难以破解
- 缺点：算法比较耗时，为了安全，可以接受
3. 创建项目

3. 创建认证模块

private PrivateKey privateKey;
@PostConstruct
public void createRsaKey() throws Exception {
publicKey = RsaUtils.getPublicKey(publicKeyFile);
privateKey = RsaUtils.getPrivateKey(privateKeyFile);
}
}
3. 创建认证服务启动类
@SpringBootApplication
@MapperScan("com.example.mapper")
@EnableConfigurationProperties(RsaKeyProperties.class)
public class AuthServerApplication {
public static void main(String[] args) {
SpringApplication.run(AuthServerApplication.class, args);
}
}4. 编写认证过滤器
public class JwtLoginFilter extends UsernamePasswordAuthenticationFilter {
private AuthenticationManager authenticationManager;
private RsaKeyProperties prop;
public JwtLoginFilter(AuthenticationManager authenticationManager, RsaKeyProperties prop) {
this.authenticationManager = authenticationManager;
this.prop = prop;
}
//重写springsecurity获取用户名和密码操作
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
try {
//从输入流中获取用户名和密码，而不是表单
SysUser sysUser = new ObjectMapper().readValue(request.getInputStream(), SysUser.class);
UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(sysUser.getUsername(), sysUser.getPassword());
return authenticationManager.authenticate(authRequest);
} catch (Exception e) {
try {
//处理失败请求
response.setContentType("application/json;charset=utf-8");
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
PrintWriter out = response.getWriter();
Map map = new HashMap<>();
map.put("code", HttpServletResponse.SC_UNAUTHORIZED);
map.put("msg", "用户名或者密码错误");
out.write(new ObjectMapper().writeValueAsString(map));
out.flush();
out.close();
} catch (Exception e1) {
e1.printStackTrace();
}
throw new RuntimeException(e);
}
}
//重写用户名密码授权成功操作----返回token凭证
protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException {
//从authResult获取认证成功的用户信息
SysUser resultUser = new SysUser();
SysUser authUser = (SysUser) authResult.getPrincipal();
resultUser.setUsername(authUser.getUsername());
resultUser.setId(authUser.getId());
resultUser.setStatus(authUser.getStatus());
resultUser.setRoles((List<SysRole>) authResult.getAuthorities());
String token = JwtUtils.generateTokenExpireInMinutes(resultUser, prop.getPrivateKey(), 3600*24);
//将token写入header
response.addHeader("Authorization", "Bearer " + token);
try {
//登录成功時，返回json格式进行提示
response.setContentType("application/json;charset=utf-8");
response.setStatus(HttpServletResponse.SC_OK);
PrintWriter out = response.getWriter();
Map<String, Object> map = new HashMap<String, Object>();
map.put("code", HttpServletResponse.SC_OK);
map.put("message", "登陆成功！");
out.write(new ObjectMapper().writeValueAsString(map));
out.flush();
out.close();
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
5. 编写检验token过滤器
public class JwtVerifyFilter extends BasicAuthenticationFilter {
private RsaKeyProperties prop;
public JwtVerifyFilter(AuthenticationManager authenticationManager, RsaKeyProperties prop) {
super(authenticationManager);
this.prop = prop;
}
/**
* 过滤请求
*/
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
FilterChain chain) {
try {
//请求体的头中是否包含Authorization
String header = request.getHeader("Authorization");
//Authorization中是否包含Bearer，不包含直接返回
if (header == null || !header.startsWith("Bearer ")) {
chain.doFilter(request, response);
responseJson(response);
return;
}
//获取权限失败，会抛出异常
UsernamePasswordAuthenticationToken authentication = getAuthentication(request);
//获取后，将Authentication写入SecurityContextHolder中供后序使用
SecurityContextHolder.getContext().setAuthentication(authentication);
chain.doFilter(request, response);
} catch (Exception e) {
responseJson(response);
e.printStackTrace();
}
}
/**
* 未登录提示
*
* @param response
*/
private void responseJson(HttpServletResponse response) {
try {
//未登录提示
response.setContentType("application/json;charset=utf-8");
response.setStatus(HttpServletResponse.SC_FORBIDDEN);
PrintWriter out = response.getWriter();
Map<String, Object> map = new HashMap<String, Object>();
map.put("code", HttpServletResponse.SC_FORBIDDEN);
map.put("message", "请登录！");
out.write(new ObjectMapper().writeValueAsString(map));
out.flush();
out.close();
} catch (Exception e1) {
e1.printStackTrace();
}
}
/**
* 通过token，获取用户信息
*
* @param request
* @return
*/
private UsernamePasswordAuthenticationToken getAuthentication(HttpServletRequest request) {
String token = request.getHeader("Authorization");
if (token != null) {
//通过token解析出载荷信息
Payload<SysUser> payload = JwtUtils.getInfoFromToken(token.replace("Bearer ", ""),
prop.getPublicKey(), SysUser.class);
SysUser user = payload.getUserInfo();
//不为null，返回
if (user != null) {
return new UsernamePasswordAuthenticationToken(user, null, user.getRoles());
}
return null;
}
return null;
}
}6. 编写SpringSecurity配置类
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserService userService;
@Autowired
private BCryptPasswordEncoder bCryptPasswordEncoder;
@Autowired
private RsaKeyProperties prop;
@Bean
public BCryptPasswordEncoder myPasswordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
//关闭跨站请求防护
.cors()
.and()
.csrf()
.disable()
//允许不登陆就可以访问的方法，多个用逗号分隔
.authorizeRequests()
.antMatchers("/product").hasAnyRole("ROLE_USER")
//其他的需要授权后访问
.anyRequest().authenticated()
.and()
//增加自定义认证过滤器
.addFilter(new JwtLoginFilter(authenticationManager(), prop))
//增加自定义验证认证过滤器
.addFilter(new JwtVerifyFilter(authenticationManager(), prop))
// 前后端分离是无状态的，不用session了，直接禁用。
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
//UserDetailsService类
auth.userDetailsService(userService)
//加密策略
.passwordEncoder(bCryptPasswordEncoder);
}
}7. 启动测试认证服务
认证成功会返回token
4. 资源模块
资源服务可以有很多个，这里只拿产品服务为例，记住，资源服务中只能通过公钥验证认证。不能签发token！

/**

}5. 编写SpringSecurity配置类
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserService userService;
@Autowired
private BCryptPasswordEncoder bCryptPasswordEncoder;
@Autowired
private RsaKeyProperties prop;
@Bean
public BCryptPasswordEncoder myPasswordEncoder() {
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
//关闭跨站请求防护
.cors()
.and()
.csrf()
.disable()
//允许不登陆就可以访问的方法，多个用逗号分隔
.authorizeRequests()
.antMatchers("/product").hasAnyRole("ROLE_USER")
//其他的需要授权后访问
.anyRequest().authenticated()
.and()
//增加自定义验证认证过滤器
.addFilter(new JwtVerifyFilter(authenticationManager(), prop))
// 前后端分离是无状态的，不用session了，直接禁用。
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
//UserDetailsService类
auth.userDetailsService(userService)
//加密策略
.passwordEncoder(bCryptPasswordEncoder);
}
}6. 编写测试产品控制器
@RestController
@RequestMapping("/product")
public class ProductController {
@Secured("ROLE_PRODUCT")
@RequestMapping("/list")
public String findAll(){
return "产品测试成功！";
}
}
7. 启动产品服务做测试
当不包含ROLE_PRODUCT权限的用户访问时会被阻止
当包含ROLE_PRODUCT权限的用户认证后会被允许访问
