本篇文章为大家展示了怎么在shiro使用ssm框架,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
1.在pom.xml中引入依赖
<!-- shiro --> <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-core --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.6.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-web --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.6.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-spring --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.6.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-ehcache --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-ehcache</artifactId> <version>1.6.0</version> </dependency>
2.新建并配置缓存ehcache.xml
<ehcache> <!-- Sets the path to the directory where cache .data files are created. If the path is a Java System Property it is replaced by its value in the running VM. The following properties are translated: user.home - User's home directory user.dir - User's current working directory java.io.tmpdir - Default temp file path --> <diskStore path="java.io.tmpdir"/> <cache name="authorizationCache" eternal="false" timeToIdleSeconds="3600" timeToLiveSeconds="0" overflowToDisk="false" statistics="true"> </cache> <cache name="authenticationCache" eternal="false" timeToIdleSeconds="3600" timeToLiveSeconds="0" overflowToDisk="false" statistics="true"> </cache> <cache name="shiro-activeSessionCache" eternal="false" timeToIdleSeconds="3600" timeToLiveSeconds="0" overflowToDisk="false" statistics="true"> </cache> <!--Default Cache configuration. These will applied to caches programmatically created through the CacheManager. The following attributes are required for defaultCache: maxInMemory - Sets the maximum number of objects that will be created in memory eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the element is never expired. timeToIdleSeconds - Sets the time to idle for an element before it expires. Is only used if the element is not eternal. Idle time is now - last accessed time timeToLiveSeconds - Sets the time to live for an element before it expires. Is only used if the element is not eternal. TTL is now - creation time overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache has reached the maxInMemory limit. --> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" /> <!--Predefined caches. Add your cache configuration settings here. If you do not have a configuration for your cache a WARNING will be issued when the CacheManager starts The following attributes are required for defaultCache: name - Sets the name of the cache. This is used to identify the cache. It must be unique. maxInMemory - Sets the maximum number of objects that will be created in memory eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the element is never expired. timeToIdleSeconds - Sets the time to idle for an element before it expires. Is only used if the element is not eternal. Idle time is now - last accessed time timeToLiveSeconds - Sets the time to live for an element before it expires. Is only used if the element is not eternal. TTL is now - creation time overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache has reached the maxInMemory limit. --> <!-- Sample cache named sampleCache1 This cache contains a maximum in memory of 10000 elements, and will expire an element if it is idle for more than 5 minutes and lives for more than 10 minutes. If there are more than 10000 elements it will overflow to the disk cache, which in this configuration will go to wherever java.io.tmp is defined on your system. On a standard Linux system this will be /tmp" --> <cache name="sampleCache1" maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="300" timeToLiveSeconds="600" overflowToDisk="true" /> <!-- Sample cache named sampleCache2 This cache contains 1000 elements. Elements will always be held in memory. They are not expired. --> <cache name="sampleCache2" maxElementsInMemory="1000" eternal="true" timeToIdleSeconds="0" timeToLiveSeconds="0" overflowToDisk="false" /> <!-- Place configuration for your caches following --></ehcache>
3.在spring配置文件applicationContext.xml配置shiro
<?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" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- spring 配置文件 主要配置和业务逻辑有关的 --> <context:property-placeholder location="classpath:dbconfig.properties"/> <!-- 数据源 --> <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="user" value="${jdbc.user}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <context:component-scan base-package="com.liuzhan"> <!-- 不能扫描控制器 --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 配置和mybatis的整合 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 指定mybatis 全局配置文件的位置 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <property name="dataSource" ref="pooledDataSource"></property> <!-- 指定mybatismapper文件的位置 --><!-- <property name="mapperLocations" value="classpath:mapper @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("开始授权"); String uName = principalCollection.getPrimaryPrincipal().toString() ; SimpleAuthorizationInfo info = new SimpleAuthorizationInfo() ; List<Users> list=userService.loginCheck(uName); //查询当前用户的角色,放在roleName中 Set<String> roleName = new HashSet<>(); roleName.add(list.get(0).getRole()); //查询角色具有的权限,放在permissions中 Set<String> permissions = new HashSet<>(); permissions.add("manage other users"); //把角色和权限放在授权类的对象中 info.addRole(list.get(0).getRole()); info.addStringPermission("manage other users"); System.out.println("当前用户角色:"+info.getRoles()); return info; } //认证 //用户输入用户名和密码后,在controller调用login(token),进行认证,这边通过用户名查询密码 //和token中用户名和密码进行比对,成功认证或失败 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { System.out.println("开始登录认证"); //获取用户名,去数据库取对应密码 String uName = (String) authenticationToken.getPrincipal(); List<Users> list=userService.loginCheck(uName); if(list.size()>0){ System.out.println("用户存在"); String uPwd=list.get(0).getuPwd(); // 用户名存在,去数据库中去获取密码 // 然后和token的用户名和密码对比 // 第三个参数是选择realm,当有多个自定义realm时有用 SimpleAuthenticationInfo info=new SimpleAuthenticationInfo(uName, uPwd, "ShiroRealm"); return info; } else{ System.out.println("用户不存在"); return null; } }}
5.controller中相关代码
package com.liuzhan.controller;import com.liuzhan.entity.Users;import com.liuzhan.service.UserService;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.UsernamePasswordToken;import org.apache.shiro.subject.Subject;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class UserController { @Autowired UserService userService; @RequestMapping("/login") public String loginCheck(Users users){ Subject subject=SecurityUtils.getSubject(); if(!subject.isAuthenticated()) { UsernamePasswordToken token=new UsernamePasswordToken(users.getuName(),users.getuPwd()); token.setRememberMe(true); try { //执行登录,会调用认证方法,如果认证失败,会抛出异常,执行catch subject.login(token); } catch (AuthenticationException e) { // TODO Auto-generated catch block System.out.println("登录失败:"+e.getMessage()); return "login"; } } //login(token)认证成功会执行这些语句 System.out.println("登录成功"); //这里如果直接 return "WEB-INF/jsp/index"的话,由于默认转发,地址栏不变,还是http://localhost:8080/ssm_shiro_war_exploded/login //仍然执行/login = anon过滤规则,不会执行下面的权限验证过滤规则 /**=user,roles[admin] //因此需要使用重定向"redirect:index",才能让 /**=user,roles[admin]过滤规则生效 return "redirect:index"; } @RequestMapping("/index") public String index() { return "WEB-INF/jsp/index"; }}
这里到dao service entity就不再粘贴代码了
6.数据库连接配置相关
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm-shiro?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8jdbc.driverClass=com.mysql.cj.jdbc.Driverjdbc.user=rootjdbc.password=root
applicationContext.xml
项目中用到的是通用mapper,实体类的类名和数据库的表名对应,实体类的属性和数据库表的字段名对应
测试
运行项目
因为我shiro过滤链配置的是只有角色为admin的能进首页,角色为user不能进首页,会被拦截(数据库jake为admin,tom为user)
运行结果:
