Shiro入门学习六

Spring集成

spring整合所需的jar包：

（1）web.xml配置如下：

 <!-- ==================================================================         spring配置     ================================================================== -->  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:applicationContext.xml</param-value>       </context-param>  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <!-- ==================================================================         springmvc配置         ================================================================== -->  <servlet>    <servlet-name>springmvc</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <load-on-startup>1</load-on-startup>    <init-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:springmvc.xml</param-value>    </init-param>  </servlet>  <servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>/*</url-pattern>  </servlet-mapping>   <!-- ==================================================================       shiro Filter 配置         ================================================================== -->    <!-- 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>    <!--不配置默认为shiroFilter-->    <init-param>        <param-name>targetBeanName</param-name>        <param-value>shiroFilter</param-value>          </init-param>  </filter>  <filter-mapping>    <filter-name>shiroFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>

DelegatingFilterProxy作用是自动到Spring容器查找名字为shiroFilter（filter-name）的bean并把所有的Filter的操作委托给它。

（2）springmvc配置 springmvc.xml（src目录下）:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    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-4.3.xsd        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-4.3.xsd">    <context:component-scan base-package="com.shiro.controller" />    <mvc:annotation-driven></mvc:annotation-driven>    <mvc:default-servlet-handler/>    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/"></property>        <property name="suffix" value=".jsp"></property>     </bean></beans>

（3）spring配置 applicationContext.xml（src目录下）:

<?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">    <!-- 数据库连接池 -->    <bean id="dataSource"

           <value>                /index.jsp = anon                /unauthorized.jsp = anon                /login.jsp = authc                /logout = logout                /** = user            </value>        </property>    </bean>    <!-- Shiro生命周期处理器-->    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/></beans>

（4）ehcache配置ehcache.xml(src目录下，暂时不用管它具体配置):

<ehcache name="shirocache">    <diskStore path="java.io.tmpdir"/>    <cache name="authorizationCache"           maxEntriesLocalHeap="2000"           eternal="false"           timeToIdleSeconds="3600"           timeToLiveSeconds="0"           overflowToDisk="false"           statistics="true">    </cache>    <cache name="authenticationCache"           maxEntriesLocalHeap="2000"           eternal="false"           timeToIdleSeconds="3600"           timeToLiveSeconds="0"           overflowToDisk="false"           statistics="true">    </cache>    <cache name="shiro-activeSessionCache"           maxEntriesLocalHeap="2000"           eternal="false"           timeToIdleSeconds="3600"           timeToLiveSeconds="0"           overflowToDisk="false"           statistics="true">    </cache></ehcache>

（5）配置文件基本完成，认证思路分析：

1.获取当前Subject
2.测试当前用户是否已经被认证
3.若没有被认证，则把用户名和密码封装为UsernamePasswordToken对象
1）.创建一个表单
2）.把请求提交到SpringMVC的handler
3）.获取用户名和密码
4.执行登录，调用Subject的login方法，委托给SecurityManager的login方法
5.自定义Realm的方法，从数据库获取用户名和密码，返回给shiro
1）.继承org.apache.shiro.realm.AuthenticationRealm
2）.实现doGetAuthenticationInfo

（6）创建login.jsp、index.jsp、unauthorized.jsp用于测试：

<h1>Login Page</h1>    <form action="shiro/login" method="post">        username:<input type="text" name="username"/><br/><br/>        password:<input type="password" name="password"/><br/><br/>        <input type="submit"/>      </form>

<h1>Index Page</h1><a href="shiro/logout">logout</a>

（7）Handler页面：

package com.shiro.controller;@Controller@RequestMapping("/shiro")public class ShiroHandler {    private Logger log = LoggerFactory.getLogger(ShiroHandler.class);    @RequestMapping("/login")    public String login(@RequestParam("username") String username,@RequestParam("password") String password){        Subject subject = SecurityUtils.getSubject();        if(!subject.isAuthenticated()){            UsernamePasswordToken token = new UsernamePasswordToken(username,password);            token.setRememberMe(true);            try{                subject.login(token);            }catch(AuthenticationException ae){                System.out.println("登录失败："+ae.getMessage());            }        }        return "redirect:/list.jsp";    }}

（8）编写ShiroRealm类，继承AuthorizingRealm不仅提供认证的方法，也提供授权

package com.shiro.realm;

Shiro 权限注解

Shiro 提供了相应的注解用于权限控制，如果使用这些注解就需要使用 AOP 的功能来进行判断，如 Spring AOP；Shiro 提供了 Spring AOP 集成用于权限注解的解析和验证。
在 spring-mvc.xml 配置文件添加 Shiro Spring AOP 权限注解的支持：

<aop:config proxy-target-class="true"></aop:config><bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">    <property name="securityManager" ref="securityManager"/></bean>

如上配置用于开启 Shiro Spring AOP 权限注解的支持； 表示代理类。

权限注解

@RequiresAuthentication

表示当前 Subject 已经通过 login 进行了身份验证；即 Subject.isAuthenticated() 返回 true。

@RequiresUser

表示当前 Subject 已经身份验证或者通过记住我登录的。

@RequiresGuest

表示当前 Subject 没有身份验证或通过记住我登录过，即是游客身份。

@RequiresRoles(value={“admin”, “user”}, logical= Logical.AND)

表示当前 Subject 需要角色 admin 和 user。

@RequiresPermissions (value={“user:a”, “user:b”}, logical= Logical.OR)

表示当前 Subject 需要权限 user：a 或 user：b。

SSL

对于SSL的支持，Shiro只是判断当前url是否需要SSL登录，如果需要自动重定向到 https 进行访问。

首先生成数字证书，生成证书到D:/localhost.keystore
使用JDK的keytool命令，生成证书（包含证书/公钥/私钥）到D:/localhost.keystore:

keytool -genkey -keystore "D:\localhost.keystore" -alias localhost -keyalg RSA

然后设置tomcat下的server.xml
此处使用了apache-tomcat-7.0.62版本，打开conf/server.xml，找到：

 <!--    <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"               clientAuth="false" sslProtocol="TLS" />    -->

替换为

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"               clientAuth="false" sslProtocol="TLS"                keystoreFile="D:\localhost.keystore" keystorePass="yt1994"/>               <!--keystorePass 就是生成 keystore 时设置的密码。-->

添加SSL到配置文件（spring-shiro.xml）

 <!-- SSL 默认端口是443,此处使用了8443-->    <bean id="sslFilter" class="org.apache.shiro.web.filter.authz.SslFilter">        <property name="port" value="8443"></property>    </bean>

Maven Jetty 插件，可以使用如下配置：

<plugin>   <groupId>org.mortbay.jetty</groupId>   <artifactId>jetty-maven-plugin</artifactId>   <version>8.1.8.v20121106</version>   <configuration>     <webAppConfig>       <contextPath>/${project.build.finalName}</contextPath>     </webAppConfig>     <connectors>     <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">       <port>8080</port>     </connector>     <connector implementation="org.eclipse.jetty.server.ssl.SslSocketConnector">       <port>8443</port>       <keystore>${project.basedir}/localhost.keystore</keystore>       <password>yt1994</password>       <keyPassword>yt1994</keyPassword>     </connector>     </connectors>   </configuration></plugin>
