Spring mvc+shiro+ehcache整合

Spring mvc+shiro+ehcache整合(详细配置)

发现最近写博客写的少了，正好有时间，把shiro的配置步骤搞上来

本项目是spring mvc整合shiro,用了md5加密，各种配置文件都是从官方例子中拷贝来，注释比较多，

此项目目前只涉及简单的登陆验证。

1.没用maven，直接贴jar包地址：http://download.csdn.net/detail/java__han/9903446

2.web.xml配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">  <display-name>shiro1</display-name>  <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>login.jsp</welcome-file>    <welcome-file>default.html</welcome-file>    <welcome-file>default.htm</welcome-file>    <welcome-file>default.jsp</welcome-file>  </welcome-file-list>    <!-- needed for ContextLoaderListener --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><!-- Bootstraps the root web application context before servlet initialization --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- The front controller of this Spring Web application, responsible for handling all application requests --><servlet><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><!-- Map all requests to the DispatcherServlet for handling --><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>/</url-pattern></servlet-mapping>  <!--   1.配置shiro拦截器 2.DelegatingFilterProxy实际上是Filterde 的一个代理对象。默认情况下Spring 会在IOC 容器中查找<filter-name>对应的filter bean.也可以通过targetBeanName的初始化参数来配置filter bean的id  -->  <!-- ==================================================================         Filters         ================================================================== -->    <!-- Shiro Filter is defined in the spring application context: -->    <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>     </web-app>

3.配置的spring-servlet.xml：

<?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:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"><context:component-scan base-package="com.hc.shiro.ce"></context:component-scan><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/"></property><property name="suffix" value=".jsp"></property></bean><mvc:annotation-driven></mvc:annotation-driven><mvc:default-servlet-handler/></beans>

4.applicationContext.xml：实现了md5加密，如果不需要，请自行去掉

<?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"/>        <property name="realm" ref="jdbcRealm"/>    </bean>    <!-- Let's use some enterprise caching support for better performance.

5.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.

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. 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.

6.ShiroRealm.java：注意package的路径

package com.hc.shiro.ce.realms;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.authc.credential.CredentialsMatcher;import org.apache.shiro.authc.credential.HashedCredentialsMatcher;import org.apache.shiro.crypto.hash.SimpleHash;import org.apache.shiro.realm.AuthenticatingRealm;import org.apache.shiro.util.ByteSource;public class ShiroRealm extends  AuthenticatingRealm {@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("进入"+token);//1.把AuthenticationToken转换为UsernamePasswordTokenUsernamePasswordToken uptoken = (UsernamePasswordToken) token;//2.从UsernamePasswordToken获取usernameString username= uptoken.getUsername();//3.调用数据库的方法，获取数据库中的username对应的用户记录System.out.println("从数据库查询数据username:"+username+"对应的信息");//4.若用户不存在，则可以抛出异常UnknownAccountExceptionif("unname".equals(username)){throw new UnknownAccountException("用户不存在");}//5.根据用户信息，决定是否需要抛出其他u异常if("dahuang".equals(username)){throw new LockedAccountException("用户被锁定");}//6.根据用户的情况构建AuthenticationInfo对象并返回，通常使用//以下信息是从数据库获取的//1.principal:认证的实体信息。可以是username,也可以是数据库对应的用户实体对象Object principal= username;//2.credentials：密码Object credentials="fc1709d0a95a6be30bc5926fdb7f22f4";//realmName:当前realm对象的name,调用父类的getName()方法即可String realmName= getName();SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(principal, credentials, realmName);return info;}public static void main(String[] args) {String hashAlgorithmName = "MD5";Object credentials = "123456";Object salt = ByteSource.Util.bytes("user");int hashIterations = 1024;Object result = new SimpleHash(hashAlgorithmName, credentials, null, hashIterations);System.out.println(result);}}

7.写个登陆的控制器UserAction.java

package com.hc.shiro.ce.action;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;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.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller@RequestMapping("/shiro")public class UserAction {private Log log = LogFactory.getLog(UserAction.class);@RequestMapping("/login")public String login(String name,String password){   Subject currentUser = SecurityUtils.getSubject();   // Do some stuff with a Session (no need for a web or EJB container!!!)        //测试使用session        //获取session 调用Subject.getSession()         /*Session session = currentUser.getSession();        session.setAttribute("someKey", "aValue");        String value = (String) session.getAttribute("someKey");        if (value.equals("aValue")) {            log.info("--》Retrieved the correct value! [" + value + "]");        }*/        // let's login the current user so we can check against roles and permissions:        //测试当前的用户是否已经被认证，既是否已经登录        //调用Subject 的isAuthenticated        if (!currentUser.isAuthenticated()) {        //吧用户名和密码封装成UsernamePasswordToken            UsernamePasswordToken token = new UsernamePasswordToken(name, password);            //RememberMe            token.setRememberMe(true);            try {            //执行登录                currentUser.login(token);            }           /* //若没有指定的账户，shiro会抛出UnknownAccountException            catch (UnknownAccountException uae) {                log.info("There is no user with username of " + token.getPrincipal());            }             //密码不对，shiro会抛出IncorrectCredentialsException            catch (IncorrectCredentialsException ice) {                log.info("Password for account " + token.getPrincipal() + " was incorrect!");            }             //用户被锁定异常            catch (LockedAccountException lae) {                log.info("The account for username " + token.getPrincipal() + " is locked.  " +                        "Please contact your administrator to unlock it.");            }*/            // ... catch more exceptions here (maybe custom ones specific to your application?            //所有认证异常的父类            catch (AuthenticationException e) {               System.out.println("登录失败:  "+e.getMessage());            }        }return "redirect:/list.jsp";}}

8.登陆页面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=ISO-8859-1"><title>Insert title here</title></head><body><h1>登陆页面</h1><form action="shiro/login" method="post">username:<input type="text" name="name"><br>password:<input type="text" name="password"><br><input type="submit" value="提交"></form></body></html>

9.登陆成功的页面list.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=ISO-8859-1"><title>Insert title here</title></head><body><h1>登陆成功页面</h1><a href="shiro/logout">logout</a></body></html>
