spring中集成shiro进行安全管理

shiro是一款轻量级的安全框架，提供认证、授权、加密和会话管理四个基础功能，除此之外也提供了很好的系统集成方案。

下面将它集成到之前的demo中，在之前spring中使用aop配置事务这篇所附代码的基础上进行集成

一、添加jar包引用

修改pom.xml文件，加入：

<!-- security -->

<dependency>

    <groupId>org.apache.shiro</groupId>

    <artifactId>shiro-core</artifactId>

    <version>1.2.5</version>

</dependency>

<dependency>

    <groupId>org.apache.shiro</groupId>

    <artifactId>shiro-spring</artifactId>

    <version>1.2.5</version>

</dependency>

<dependency>

    <groupId>org.apache.shiro</groupId>

    <artifactId>shiro-cas</artifactId>

    <version>1.2.5</version>

</dependency>

<dependency>

    <groupId>org.apache.shiro</groupId>

    <artifactId>shiro-web</artifactId>

    <version>1.2.5</version>

</dependency>

<dependency>

    <groupId>org.apache.shiro</groupId>

    <artifactId>shiro-ehcache</artifactId>

    <version>1.2.5</version>

</dependency>

二、添加过滤器Filter

修改web.xml文件，加入（需要加在Filter比较靠前的位置）：

<!-- Shiro过滤器 -->

<filter>

    <filter-name>shiroFilter</filter-name>

    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

    <init-param>

        <param-name>targetFilterLifecycle</param-name>

        <param-value>true</param-value>

    </init-param>

</filter>

<filter-mapping>

    <filter-name>shiroFilter</filter-name>

    <url-pattern>/*</url-pattern>

</filter-mapping>

三、添加配置文件

在"src/main/resources"代码文件夹中新建文件"spring-context-shiro.xml"，内容为：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="

        http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

        http://www.springframework.org/schema/context

        http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <description>Shiro Configuration</description>

    <!-- 加载配置属性文件 -->

    <context:property-placeholder ignore-unresolvable="true" location="classpath:demo.properties" />

    <!-- 定义安全管理配置 -->

    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">

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

        <property name="sessionManager" ref="defaultWebSessionManager" />

        <!-- <property name="cacheManager" ref="shiroCacheManager" /> -->

    </bean>

    <bean id="userRealm" class="org.xs.demo1.UserRealm"></bean>

    <!-- 自定义会话管理 -->

    <bean id="defaultWebSessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager">

        <!-- 会话超时时间，单位：毫秒 -->

        <property name="globalSessionTimeout" value="86400000" />

        <!-- 定时清理失效会话, 清理用户直接关闭浏览器造成的孤立会话 -->

        <property name="sessionValidationInterval" value="120000"/>

        <!-- 定时检查失效的会话 -->

        <property name="sessionValidationSchedulerEnabled" value="true"/>

    </bean>

    <!-- 安全认证过滤器 -->

    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">

        <property name="securityManager" ref="securityManager" />

        <property name="loginUrl" value="/hello/login" />

        <property name="unauthorizedUrl" value="/hello/login" />

        <property name="successUrl" value="/hello/mysql" />

        <property name="filterChainDefinitions">

            <value>

                /hello/login = anon //anon:允许匿名访问

                /hello/auth = anon

                /hello/* = authc //authc:需要认证才能访问

            </value>

        </property>

    </bean>

    <!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->

    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

</beans>

四、增加安全认证实现类

在"src/main/java"代码文件夹的"org.xs.demo1"的包下新建"UserRealm.java"

package org.xs.demo1;

import org.apache.shiro.authc.AuthenticationException;

import org.apache.shiro.authc.AuthenticationInfo;

import org.apache.shiro.authc.AuthenticationToken;

import org.apache.shiro.authc.SimpleAuthenticationInfo;

import org.apache.shiro.authc.UsernamePasswordToken;

import org.apache.shiro.authz.AuthorizationInfo;

import org.apache.shiro.authz.SimpleAuthorizationInfo;

import org.apache.shiro.realm.AuthorizingRealm;

import org.apache.shiro.subject.PrincipalCollection;

import org.springframework.stereotype.Service;

/**

 * 安全认证实现类

 */

@Service

public class UserRealm extends AuthorizingRealm {

    /**

     * 获取授权信息

     */

    @Override

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {

        //String currentUsername = (String) getAvailablePrincipal(principals);

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        info.addStringPermission("admin");

        return info;

    }

    /**

     * 获取认证信息

     */

    @Override

    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {

        UsernamePasswordToken token = (UsernamePasswordToken) authcToken;

        String username = token.getUsername();

        if (username != null && !"".equals(username)) {

            return new SimpleAuthenticationInfo("xs", "123", getName());

        }

        return null;

    }

}

五、增加Controller方法

在HelloController类里添加方法：

/**

 * 登录页

 */

@RequestMapping("login")

public String login() throws Exception {

    return "login";

}

/**

 * 登录验证

 */

@RequestMapping("auth")

public String auth(String loginName, String loginPwd) throws Exception {

    SecurityUtils.getSecurityManager().logout(SecurityUtils.getSubject());

    if(!"xs".equals(loginName) || !"123".equals(loginPwd)) {

        return "redirect:/hello/login";

    }

    UsernamePasswordToken token = new UsernamePasswordToken(loginName, loginPwd);

    Subject subject = SecurityUtils.getSubject();

    subject.login(token);

    return "redirect:/hello/mysql";

}

六、增加login.jsp页面

在WEB-INF的views文件夹中新建"login.jsp"

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

    <head>

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        <title>Insert title here</title>

        <%

            /* 当前基础url地址 */

            String path = request.getContextPath();

            request.setAttribute("path", path);

        %>

    </head>

    <body>

        <form action="${path}/hello/auth" method="post">

            登录名称：<input type="text"  name="loginName" value="${userInfo.loginName}" />

            登录密码：<input type="text"  name="loginPwd" value="${userInfo.loginPwd}" />

            <input type="submit"  class="btn btn-default btn-xs" value="保存" />

        </form>

    </body>

</html>

七、运行测试

访问"http://localhost:8080/demo1/hello/mysql"的地址，页面会被跳转到登陆页：

输入用户名"xs"和密码"123"，然后点击登录，就能跳转到mysql：
