以检验用户登录为例，进行shiro与spring、mybatis整合

1、创建mavenWeb项目

2、在pom.xml中增加所需要依赖的jar包

	</dependency>
	

  </dependencies>

3、配置web.xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>ShiroWeb</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
    <!-- shiro过滤器定义 -->
	<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>/*</url-pattern>  
	</filter-mapping>
	
	
    <!-- Spring配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	<!-- 编码过滤器 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<async-supported>true</async-supported>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<!-- Spring监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!-- 添加对springmvc的支持 -->
	<servlet>
		<servlet-name>springMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
		<async-supported>true</async-supported>
	</servlet>
	<servlet-mapping>
		<servlet-name>springMVC</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	
	
</web-app>

4、配置applicationContext.xml、log4j.properties、mybatis-config.xml、spring-mvc.xml等配置文件

applicationContext.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:aop="http://www.springframework.org/schema/aop"   
    xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:jee="http://www.springframework.org/schema/jee"  
    xmlns:tx="http://www.springframework.org/schema/tx"  
    xsi:schemaLocation="

		<!-- 自动扫描mappers.xml文件 -->
		<property name="mapperLocations" value="classpath:com/yang/mappers/*.xml"></property>
		<!-- mybatis配置文件 -->
		<property name="configLocation" value="classpath:mybatis-config.xml"></property>
	</bean>

	<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.yang.dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>

	<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
	
	<!-- 自定义Realm -->
	<bean id="myRealm" class="com.yang.realm.MyRealm"/>  
	
	<!-- 安全管理器 -->
	<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">

	        <value>  
	             /login=anon
				/admin*=authc

				/teacher=perms["user:create"]
	        </value>  
	    </property>
	</bean>  
	
	<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->  
	<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>  
	
	<!-- 开启Shiro注解 -->
	<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/>  
  		<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">  
  	  <property name="securityManager" ref="securityManager"/>  
    </bean>  
  
	<!-- 配置事务通知属性 -->  
    <tx:advice id="txAdvice" transaction-manager="transactionManager">  
        <!-- 定义事务传播属性 -->  
        <tx:attributes>  
            <tx:method name="insert*" propagation="REQUIRED" />  
            <tx:method name="update*" propagation="REQUIRED" />  
            <tx:method name="edit*" propagation="REQUIRED" />  
            <tx:method name="save*" propagation="REQUIRED" />  
            <tx:method name="add*" propagation="REQUIRED" />  
            <tx:method name="new*" propagation="REQUIRED" />  
            <tx:method name="set*" propagation="REQUIRED" />  
            <tx:method name="remove*" propagation="REQUIRED" />  
            <tx:method name="delete*" propagation="REQUIRED" />  
            <tx:method name="change*" propagation="REQUIRED" />  
            <tx:method name="check*" propagation="REQUIRED" />  
            <tx:method name="get*" propagation="REQUIRED" read-only="true" />  
            <tx:method name="find*" propagation="REQUIRED" read-only="true" />  
            <tx:method name="load*" propagation="REQUIRED" read-only="true" />  
            <tx:method name="*" propagation="REQUIRED" read-only="true" />  
        </tx:attributes>  
    </tx:advice>  
  
    <!-- 配置事务切面 -->  
    <aop:config>  
        <aop:pointcut id="serviceOperation"  
            expression="execution(* com.yang.service.*.*(..))" />  
        <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" />  
    </aop:config>  
    
   
</beans>

mybatis-config.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<!-- 别名 -->
	<typeAliases>
		<package name="com.yang.entity"/>
	</typeAliases>
</configuration>

spring-mvc.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:p="http://www.springframework.org/schema/p"  
    xmlns:aop="http://www.springframework.org/schema/aop"   
    xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:jee="http://www.springframework.org/schema/jee"  
    xmlns:tx="http://www.springframework.org/schema/tx"  
    xsi:schemaLocation="    
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd  
        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd  
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">    

	<!-- 使用注解的包，包括子集 -->
	<context:component-scan base-package="com.yang.controller" />

	<!-- 视图解析器 -->
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/" />
		<property name="suffix" value=".jsp"></property>
	</bean>

</beans>

5、编写entity，dao，mappers，service，controller，realm等代码：

其中主要realm部分代码与上节相同，其他部分代码为简单的用户登录的业务逻辑。其中Usercontroller.java代码如下：

@Controller
@RequestMapping("/user")
public class UserController {

	
	/**
	 * 用户登录
	 * @param user
	 * @param request
	 * @return
	 */
	@RequestMapping("/login")
	public String login(User user,HttpServletRequest request){
		Subject subject=SecurityUtils.getSubject();
		UsernamePasswordToken token=new UsernamePasswordToken(user.getUserName(), user.getPassword());
		try{
			subject.login(token);
			Session session=subject.getSession();
			System.out.println("sessionId:"+session.getId());
			System.out.println("sessionHost:"+session.getHost());
			System.out.println("sessionTimeout:"+session.getTimeout());
			session.setAttribute("info", "session的数据");
			return "redirect:/success.jsp";
		}catch(Exception e){
			e.printStackTrace();
			request.setAttribute("user", user);
			request.setAttribute("errorMsg", "用户名或密码错误！");
			return "index";
		}
	}
