Shiro与Spring集成

1、shiro相关jar包的maven依赖。

<!-- Spring Shiro --><dependency>   <groupId>org.apache.shiro</groupId>   <artifactId>shiro-core</artifactId>   <version>1.2.3</version></dependency><dependency>   <groupId>org.apache.shiro</groupId>   <artifactId>shiro-web</artifactId>   <version>1.2.3</version></dependency><dependency>   <groupId>org.apache.shiro</groupId>   <artifactId>shiro-spring</artifactId>   <version>1.2.3</version></dependency><dependency>   <groupId>org.apache.shiro</groupId>   <artifactId>shiro-ehcache</artifactId>   <version>1.2.3</version></dependency><dependency>   <groupId>org.apache.shiro</groupId>   <artifactId>shiro-quartz</artifactId>   <version>1.2.3</version></dependency>

2、web.xml中shiro的相关配置。

1）引入shiro的配置文件applicationContext-shiro.xml。

<context-param>   <param-name>contextConfigLocation</param-name>   <param-value>       classpath*:/applicationContext-shiro.xml       </param-value></context-param>

2）在web.xml中配置shiroFilter过滤器。

<!-- shiro过滤器配置 --><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>

在web.xml 文件配置中配置注意的问题点：

1.如果你的项目动态请求都是*.action ，*.do 等结尾，那么拦截配置就直接配置为<url-pattern>*.action</url-pattern> 或者<url-pattern>*.do</url-pattern> 

2.过滤器配置的顺序，过滤器最好配置的位置是在org.springframework.web.filter.CharacterEncodingFilter 之后，就是处理好字符集就是Shiro的过滤器。

3、Shiro相关配置applicationContext-shiro.xml

class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">      <property name="securityManager" ref="securityManager"/>   </bean></beans>

4、Ehcache相关配置ehcache-shiro.xml

<?xml version="1.0" encoding="UTF-8"?><ehcache updateCheck="false" name="shiroCache">   <diskStore path="java.io.tmpdir"/>      <defaultCache      maxElementsInMemory="10000"      eternal="false"      timeToIdleSeconds="120"      timeToLiveSeconds="120"      overflowToDisk="false"      diskPersistent="false"      diskExpiryThreadIntervalSeconds="120" /></ehcache>

5、自定义ShiroRealm实现

import org.apache.shiro.authc.*;import org.apache.shiro.authz.AuthorizationInfo;import org.apache.shiro.authz.SimpleAuthorizationInfo;import org.apache.shiro.realm.AuthorizingRealm;import org.apache.shiro.realm.Realm;import org.apache.shiro.subject.PrincipalCollection;import org.springframework.beans.factory.annotation.Autowired;import com.gcmobile.console.system.entity.User;import com.gcmobile.console.system.mapper.UserMapper;/** * Shiro自定义域，实现认证、授权 */public class ShiroRealm extends AuthorizingRealm{   @Autowired   private UserMapper userMapper;  // 用户表mapper接口   public ShiroRealm() {      setAuthenticationTokenClass(UsernamePasswordToken.class);   }   /**    * Shiro认证方法，实现登录认证    * @param authenticationToken    * @return     */   @Override   protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) {      // 获取usernamePasswordToken里面的用户名、密码      UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) authenticationToken;      // 根据用户名查询用户信息      User user = userMapper.selectByUserName(usernamePasswordToken.getUsername());      if (user == null) {         throw new UnknownAccountException("Unknown username [" + usernamePasswordToken.getUsername() + "]");      }      if (!user.getStatus().equals(0)) {         throw new DisabledAccountException("Disabled account [" + usernamePasswordToken.getUsername() + "]");      }      // 将用户信息保存至ShiroUser实体类      ShiroUser shiroUser = new ShiroUser(user.getId(), user.getUserName());      shiroUser.setUserName(user.getName());      shiroUser.setUserId(user.getId());      // 将shiroUser用户信息及查出的密码与usernamePasswordToken中的用户名、密码进行比较，并将shiroUser实体类保存至缓存中      return new SimpleAuthenticationInfo(shiroUser, user.getPassword(), getName());   }   /**    * Shiro授权方法，实现权限控制    * @param principalCollection    * @return     */   @Override   protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {      // 取出当前已登录的用户信息      ShiroUser shiroUser = (ShiroUser) principalCollection.getPrimaryPrincipal();      SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();      System.out.print("=============");      // 将当前用户的角色放入授权信息类的角色组中      info.addRoles(userMapper.queryRolesByUserId(shiroUser.getUserId()));      // 将当前用户的权限放入授权信息类的权限组中      info.addStringPermissions(userMapper.queryPermissionsByUserId(shiroUser.getUserId()));      return info;   }}

6、ShiroUser类，自定义Authentication对象，使得Subject除了携带用户登录名外还可以携带更多信息

import java.io.Serializable;/** * 自定义Authentication对象，使得Subject除了携带用户的登录名外还可以携带更多信息. */public class ShiroUser implements Serializable {   private static final long serialVersionUID = 4999382582432113545L;   private Integer userId;   private String userName;   private String name;   public ShiroUser() {}   public ShiroUser(Integer userId, String userName) {      this.userId = userId;      this.userName = userName;   }   public Integer getUserId() {      return userId;   }   public void setUserId(Integer userId) {      this.userId = userId;   }   public String getUserName() {      return userName;   }   public void setUserName(String userName) {      this.userName = userName;   }   public String getName() {      return name;   }   public void setName(String name) {      this.name = name;   }}

7、登录调用Shiro进行认证

// 如果已登录，则先退出登录SecurityUtils.getSubject().logout();// 实例化一个subject实体Subject subject = SecurityUtils.getSubject();// UsernamePasswordToken封装用户名、密码UsernamePasswordToken token = new UsernamePasswordToken(username, MD5.toMD5(password));// 开始登录认证subject.login(token);
