一》引入shirojar包
<!-- shiro登陆权限控制 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.3.2</version>
</dependency>
二》web配置文件配置shiro过滤器
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
<!--shrio -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理 -->
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
三》导入spring-shiro.xml文件
<?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:aop="http://www.springframework.org/schema/aop"

<!-- Shiro默认会使用Servlet容器的Session,可通过sessionMode属性来指定使用Shiro原生Session -->
<bean id="adminRealm" class="com.wskj.app.shiro.AdminRealm"/>
<!-- 即<property name="sessionMode" value="native"/>,详细说明见官方文档 -->
<!-- 这里主要是设置自定义的单Realm应用,若有多个Realm,可使用'realms'属性代替 -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="adminRealm"/>
</bean>
<!-- Shiro主过滤器本身功能十分强大,其强大之处就在于它支持任何基于URL路径表达式的、自定义的过滤器的执行 -->
<!-- Web应用中,Shiro可控制的Web请求必须经过Shiro主过滤器的拦截,Shiro对基于Spring的Web应用提供了完美的支持 -->
<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"/>
<property name="loginUrl" value="/adminLogin/login.do" />
<property name="unauthorizedUrl" value="/admin/userInfo.do"></property>
<!-- anon：它对应的过滤器里面是空的,什么都没做-->
<!-- authc：该过滤器下的页面必须验证后才能访问,它是Shiro内置的一个拦截器org.apache.shiro.web.filter.authc.FormAuthenticationFilter -->
<property name="filterChainDefinitions">
<value>
/adminLogin/*.do=anon <!-- 任何人都可以访问，匿名 -->
/add*.do=perms[add]
/edit*.do=perms[edit]
/del*.do=perms[delete]
/admin/*.do=authc <!-- 需要登录 -->
/visit/*.do=authc <!-- 需要登录 -->
</value>
</property>
</bean>
</beans>
四》创建实体com.wskj.app.shiro.AdminRealm （权限控制我应用了user注意）
package com.wskj.app.shiro;
import java.util.List;
import java.util.Map;
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.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.alibaba.druid.sql.visitor.functions.Right;
import com.wskj.app.service.AdminService;
import com.wskj.app.service.UserService;
import com.wskj.app.vo.ShiroAdmin;
import com.wskj.app.vo.ShiroUser;
@Component(value="adminRealm")
public class AdminRealm extends AuthorizingRealm{
@Autowired
private AdminService adminService;
@Autowired
private UserService userService;
/**
*
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// 从用户身份集合中读到一个主要身份
ShiroUser suser = (ShiroUser) principals.getPrimaryPrincipal();
// 如果用户只做了登录，但从来没有做过权限验证，则需要先从数据库中取得当前用户的权限值，并放入到ShiroUser中
// ShiroUser是自定义的存储用户身份信息的类
if ( suser.getRights().isEmpty()) {
//查询出用户信息
Map<String, Object> usMap= userService.getUserByUserName(suser.getUserName());
Integer noid1=(Integer) usMap.get("noid");
//通过用户的noid查询出用户权限
List<String> rights=userService.getRightsbyUserId(noid1);
for (String p : rights) {
suser.getRights().add(p) ;
}
}
// 将获得的用户的角色和权限列表放入到auth中，并直接返回即可
// user_add user_edit
SimpleAuthorizationInfo auth = new SimpleAuthorizationInfo();
auth.addStringPermissions(suser.getRights());
return auth;
}
/**
*
* 做登录处理
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken arg0) throws AuthenticationException {
UsernamePasswordToken token = (UsernamePasswordToken) arg0;
String uname = token.getUsername();
Map<String , Object> ui =adminService.getAdminByName(uname);
if ( ui!=null) {
// 创建一个验证用户名和密码的
ShiroAdmin suser = new ShiroAdmin();
Integer noid=(Integer) ui.get("noid");
suser.setNoid(noid);
suser.setAdminName((String)ui.get("admin_name"));
suser.setAdminCode(uname);
SimpleAuthenticationInfo saci = new SimpleAuthenticationInfo(suser, ui.get("admin_pwd"), (String) ui.get("admin_code"));
return saci;
}
return null;
}
}
五》vo 实体建一个ShiroAdmin 把用户的验证信息存储起来
package com.wskj.app.vo;
import java.util.ArrayList;
import java.util.List;
public class ShiroAdmin {
private Integer noid;
private String adminName;
private String adminCode;
private List<String> permCodes=new ArrayList<String>();
public Integer getNoid() {
return noid;
}
public void setNoid(Integer noid) {
this.noid = noid;
}
public String getAdminName() {
return adminName;
}
public void setAdminName(String adminName) {
this.adminName = adminName;
}
public List<String> getPermCodes() {
return permCodes;
}
public void setPermCodes(List<String> permCodes) {
this.permCodes = permCodes;
}
public String getAdminCode() {
return adminCode;
}
public void setAdminCode(String adminCode) {
this.adminCode = adminCode;
}
}
至此，shiro的登陆验证就完成了
