篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了spring中集成shiro进行安全管理相关的知识,希望对你有一定的参考价值。

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:
