从头开始——SSM+Shiro实现登陆认证

Shiro功能概述：

 Shiro是一个功能强大且灵活的开源安全框架，可以清晰地处理身份验证，授权，企业会话管理和加密。

• 身份验证：有时也称为“登录”，这是证明用户是他们所说的人的行为。

• 授权：访问控制的过程，即确定“谁”可以访问“什么”。

• 会话管理：即使在非Web或EJB应用程序中，也可以管理特定于用户的会话。

• 加密：使用加密算法保持数据安全，同时仍然易于使用。

Shiro的简要概述：

我们传统的登录认证方式是,从前端页面获取到用户输入的账号和密码之后,传到后台直接去数据库查询账号和密码是否匹配和存在,如果匹配和存在就登录成功,没有就提示登陆失败

而shiro的认证方式则是,从前端页面获取到用户输入的账号和密码之后,传入给一个UsernamePasswordToken对象也就是令牌,

然后再把令牌传给subject,subject会调用自定义的 realm,

realm做的事情就是用前端用户输入的用户名,去数据库查询出一条记录(只用用户名去查,查询拿到返回用户名和密码),然后再把两个密码进行对比,不一致就跑出异常

也就是说如果subject.login(token);没有抛出异常,就表示用户名和密码是匹配的,那么就表示登录成功！

今天要做的就是在SSM项目中集成Shiro安全框架实现简单的登陆认证！

废话不多说，开干！

第一步，先看看基本的项目结构（前台页面和静态资源我已经导入了,源码会放在最后）

然后添加maven依赖

<!--声明版本-->
  <properties>
    <servlet.version>3.1.0</servlet.version>
    <jsp.version>2.3.1</jsp.version>

    <version>4.5.3</version>
  </dependency>
  </dependencies>

然后开始创建对应的接口和类

(关于项目中的实体类和mapper文件还有mapping文件的自动生成方法参见这里)

首先在realm中创建一个UserRealm继承AuthorizingRealm并重新它的两个方法

package com.sixmac.realm;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

public class UserRealm extends AuthorizingRealm {

    /**
     * 认证的时候回调
     * @param authenticationToken
     * @return
     * @throws AuthenticationException
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        return null;
    }




    /**
     * 授权的时候回调
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }


}

然后是shiro的配置文件application-shiro.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<!-- 扫描realm -->
	<context:component-scan

	<!-- 创建凭证管理器 -->

	<!--MD5加密-->
	<!--<bean id="credentialsMatcher"

	<!-- securityManager安全管理器 -->
	<bean id="securityManager"

		<property name="realm" ref="userRealm"></property>
	</bean>




	<!-- Shiro 的Web过滤器 id必须和web.xml里面的shiroFilter的 targetBeanName的值一样 -->
	<bean id="shiroFilter"
		class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
		<!-- Shiro的核心安全接口，这个属性是必须的 -->
		<property name="securityManager" ref="securityManager" />
		<!-- 要求登录时的链接(登录页面地址)，非必须的属性，默认会自动寻找Web工程根目录下的"/login.jsp"页面 -->
		<property name="loginUrl" value="/login/toLogin" />
		<!-- 登录成功后要跳转的连接(本例中此属性用不到，因为登录成功后的处理逻辑在UserController里硬编码) -->
		<!-- <property name="successUrl" value="/success.action"/> -->
		<!-- 用户访问未对其授权的资源时，所显示的连接 -->
		<property name="unauthorizedUrl" value="/refuse.jsp" />
		<!-- 过虑器链定义，从上向下顺序执行，一般将/**放在最下边 -->
		<property name="filterChainDefinitions">
			<value>
				<!-- /** = authc 所有url都必须认证通过才可以访问 -->
				/index.jsp*=anon

				/login/login*=anon
				<!-- 如果用户访问user/logout就使用Shiro注销session -->
				/login/logout = logout
				<!-- /** = anon所有url都不可以匿名访问 -->
				<!-- /** = authc -->
				<!-- /*/* = authc -->
				<!-- /** = authc所有url都不可以匿名访问 必须放到最后面 -->
				/** = authc
			</value>
		</property>
	</bean>



</beans>

然后是配置文件：application-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">


	<!-- 解析db.properties 因为 db.properties里面有username=root 如果在下面的数据源中使用${username}它取到的是当前系统的登陆名 
		如果要使用db.properties里面的username必须加system-properties-mode="FALLBACK"这个属性 -->
	<context:property-placeholder location="classpath:db.properties"
		system-properties-mode="FALLBACK" />

	<!-- 配置数据源 -->
	<bean id="dataSource"

	<!-- 配置sqlSessinoFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<!--mybatis的配置文件 -->

		<property name="mapperLocations">

		</property>
	</bean>

	<!-- Mapper接口所在包名，Spring会自动查找之中的类 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!-- 以下的配置只能指向一个包 如果配置多个呢 就在包的中间加, -->
		<property name="basePackage" value="com.sixmac.mapper" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>

</beans>

然后是application-service.xml

配置文件没问题的话就创建controller，设置页面跳转路径与登陆认证的接口~

package com.sixmac.controller;

import com.sixmac.domain.User;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpSession;

@Controller
@RequestMapping("login")
public class LoginController {


    @RequestMapping("toLogin")
    public String toLogin(){
        return "login.jsp";
    }

    @RequestMapping("login")
    public String login(String loginname, String password, Model model, HttpSession session){
        UsernamePasswordToken token = new UsernamePasswordToken(loginname, password);
        // 得到认证主体
        Subject subject = SecurityUtils.getSubject();

        try {
            //这里会加载自定义的realm
            subject.login(token); //把令牌放到login里面进行查询,如果查询账号和密码时候匹配,如果匹配就把user对象获取出来,失败就抛异常
            System.out.println("认证成功！");
            User user = (User) subject.getPrincipal();//获取登录成功的用户对象(以前是直接去service里调用方法面查)
            session.setAttribute("user",user);//放入session
            return "/system/index.jsp";

        }catch (Exception e){
            model.addAttribute("error","用户名密码不匹配！");
            return "login.jsp";
        }

    }
}

然后在自定义的realm里写shiro登陆认证的方法

package com.sixmac.realm;

import com.sixmac.domain.User;
import com.sixmac.service.LoginService;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class UserRealm extends AuthorizingRealm {

    @Autowired
    private LoginService loginService;

    /**
     * 认证的时候回调
     * @param token
     * @return
     * @throws AuthenticationException
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        UsernamePasswordToken userToken = (UsernamePasswordToken) token;//获取令牌(里面存放new UsernamePasswordToken的时候放入的账号和密码)
        String loginname = userToken.getUsername();
        User user = loginService.login(loginname);//去数据库查询用户名是否存在,如果存在返回对象(账号和密码都有的对象)
        if (user!=null){
            //参数1.用户认证的对象(Controller中subject.getPrincipal()方法返回的对象),
            //参数2.从数据库根据用户名查询到的用户密码
            //参数3.把当前自定义的realm对象传给SimpleAuthenticationInfo,在配置文件需要注入
            SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getPassword(), this.getName());
            return info;
        }else {
            return null;
        }
    }

    /**
     * 授权的时候回调
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }


}

到这里基本上就完成了shiro的登陆认证，登陆成功的页面如下：

核心代码其实就只有这么多，当然这只是最简单的一部分，shiro还有很多其他强大的功能，这里就不细说了
