springMVC 整合shiro

本人小白一枚，初次接触shiro,花了两天时间搞了一下可算能用了，当然虽然spring security功能更强大，但是太繁琐了，不容易入门，并且shiro功能感觉也完全够用了；各位童鞋可以参考别人的文章：http://jinnianshilongnian.iteye.com/blog/2049092

1、web.xml中增加spring-shiro.xml配置

<context-param>    <param-name>contextConfigLocation</param-name>    <param-value>    classpath:spring-shiro.xml,    classpath:beans.xml    </param-value>  </context-param>

不多说，和别的spring配置文件都在启动时通过contextConfigLocation一块加载

2、spring-shiro.xml内容如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><!-- ========================================================= Shiro Core Components - Not Spring Specific ========================================================= --><!-- Shiro's main business-tier object for web-enabled applications (use DefaultSecurityManager instead when there is no web environment) --><!-- 1.配置securityManager --><bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"><property name="cacheManager" ref="cacheManager" /><!-- 单个realm的时候用下面的这个 --><!-- <property name="realm" ref="jdbcRealm" /> --><!-- 多个的时候用下面这个 --><property name="authenticator" ref="authenticator" /></bean><!-- Let's use some enterprise caching support for better performance.

第一个地方，本配置文件是引用多个realm的实例，就跟spring的filter和struts的过滤器一样，你可以校验多层，我觉得一般系统一层就够了，无非就是校验用户信息，角色权限信息；

第二个地方，一定要注释，不然启用shiro的注解springmvc的注解就不好用了，提示can not autowird......

第三个地方，anon是指可以匿名登录，就是不用认证就可以调用，authc必须认证通过，session中保存了你的登录信息后你才可以配置角色权限访问别的页面。

3、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>

hibernate也有缓存，因为用的是mybatis，shiro可以整合ehcache处理缓存的问题，提高工作效率，喜欢研究的可以测试下用缓存能够提高访问速度。红色的地方只有是false的时候，下面设置的缓存时间和缓存间隔时间才能生效。

4、编写页面，我采用的ajax异步提交，通过controller返回的信息在登录首页显示认证返回的信息，成功后才跳转到index.jsp页面

$.mpbAjax("/shiro/login",{type : "POST",async : false,data : {"_method"  : "POST","userName" : $("#userName").val(),"password" : $("#password").val()},success : function(data){if($.isNotBlank(data)){if(!data.success){do_notice(data.msg);}else{$.mpbJumpNotOpen("/index.jsp");}}}});

5、controller关键代码

UsernamePasswordToken token = new UsernamePasswordToken(user.getUserName(), user.getPassword());token.setRememberMe(true);// shiro登陆验证try {SecurityUtils.getSubject().login(token);} catch (UnknownAccountException ex) {return "用户不存在！";} catch (LockedAccountException ex) {return "用户锁定!";    } catch (IncorrectCredentialsException ex) {return "用户名/密码验证失败!";} catch (Exception ex) {ex.printStackTrace();return "内部异常!";}

6、调用.login方法时，自动进入注册的过滤器ShiroRealm.java

package com.neusoft.core.shiro;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.AuthenticationInfo;import org.apache.shiro.authc.AuthenticationToken;import org.apache.shiro.authc.LockedAccountException;import org.apache.shiro.authc.SimpleAuthenticationInfo;import org.apache.shiro.authc.UnknownAccountException;import org.apache.shiro.authc.UsernamePasswordToken;import org.apache.shiro.crypto.hash.SimpleHash;import org.apache.shiro.realm.AuthenticatingRealm;import org.apache.shiro.session.Session;import org.apache.shiro.util.ByteSource;import org.springframework.beans.factory.annotation.Autowired;import com.neusoft.demo.entity.OrgUser;import com.neusoft.demo.service.UserService;public class ShiroRealm extends AuthenticatingRealm {@Autowiredprivate UserService userService;public static final String SESSION_USER_KEY = "gray";@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {UsernamePasswordToken upToken = (UsernamePasswordToken) token;String username = upToken.getUsername();// 验证用户是否可以登录          OrgUser ui = userService.selectUsers(username);if (ui == null) {throw new UnknownAccountException("用户不存在");} else if ("1".equals(ui.getDeleteFlag())) {throw new LockedAccountException("用户被锁定");}// 设置session          Session session = SecurityUtils.getSubject().getSession();          session.setAttribute(ShiroRealm.SESSION_USER_KEY, ui); // 以下信息从数据库中获取// 1 principal : 认证的实体信息，可以是username,也可以是数据表对应的实体对象。Object principal = username;// 3 realmName : 当前realm 对象的name ， 调用父类的 getName() 方法即可String realmName = getName();// 4.盐值ByteSource credentialsSalt = ByteSource.Util.bytes(username);// 这个是不加盐的 new SimpleAuthenticationInfo(principal, credentials,// realmName);SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(principal,ui.getPassword(), credentialsSalt, realmName);return info;}public UserService getUserService() {return userService;}public void setUserService(UserService userService) {this.userService = userService;}public static void main(String[] args) {String algorithmName = "MD5";Object credential = "123";Object salt = ByteSource.Util.bytes("admin");int hashIterations = 1024;Object result = new SimpleHash(algorithmName, credential, salt,hashIterations);System.out.println(result);}}

只写了个校验用户信息，还有个重写的方法校验权限和角色的，自行补脑

一定要注意，shiro过滤器在springmvc之前过滤，autowired不起作用，需要你增加get set方法注入，抛出的异常在controller捕获返回到前台；

框架搭建好了，后期增加验证码之类的就好加了
