spring ,springMVC,shiro 框架搭建。

1.  导入相关jar包。

2.完成spring的相关配置

 1） 在web.xml中完成spring的声明

　　contextLoaderListener的配置，如果是location，那么配置文件必须放到web项目的根目录中。

      如果是放到类路径下，需要改为classpath：applicationContext.xml

  2）新建spring的配置文件

      这个名称必须与web.xml中，配置的一致。如applicationContext.xml

3.完成springMVC的配置

    1）在web.xml中，配置dispatcherServlet，在location中，需要改为classpath类路径下，url改为/，

    2）新建一个springMVC的配置文件，建立在类路径下，导入相关的命名空间，如beans，mvc，context。

自动扫描，注解生效，默认处理机。至少配置这3个。<context  component-scan base-package="cn.taotao.*"/>必须写包名，不能是*，否则报bean无法初始化注解错误

<mvc:annotation-driven /><mvc:default-servlet-handler/>

      配置视图的解析器，internalResourceViewResolver,配置前缀，prefix, 和后缀名 .jsp

代码如下：

web.xml

    </servlet-mapping>
    
</web-app>

applicationContext.xml，开始的时候，不用做任何修改只要有这个文件即可。

<?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">


</beans>

spring-mvc.xml，扫描包的时候，不能用*，必须加包名，否则报bean注解无法初始化错误

<?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:context="http://www.springframework.org/schema/context"

shiro的搭建

在maven中，加入shiro-all.jar 后，maven自动加入8个jar，共9个

shiro-all.jar

shiro-guice.jar

shiro-core.jar

slf4j-api.jar

commons-beanutils.jar

guice.jar

javax.inject.jar

aopalliance.jar

guice-multibinding.jar

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-all</artifactId>
    <version>1.3.2</version>
</dependency>

在web.xml中加入shiro的代理，web.serlvet的版本应该为2.4或以上，必要时改web头文件声明

    <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>

在applicationContext.xml 中，全文件如下

<?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">

    <bean id="securityManager"
        class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="cacheManager" ref="cacheManager"></property>

        <property name="realm" ref="jdbcRealm"></property>
    </bean>

    <bean id="jdbcRealm" class="cn.taotao.bean.shiroRealm"></bean>  //实现接口org.apache.shiro.realm.Realm，自己定义这样的一个文件
    <bean id="cacheManager"
        class="org.apache.shiro.cache.ehcache.EhCacheManager">
        <property name="cacheManagerConfigFile"
            value="classpath:ehcache.xml"></property>
    </bean>

    <bean id="lifecycleBeanPostProcessor"
        class="org.apache.shiro.spring.LifecycleBeanPostProcessor"></bean>
    <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"></property>
    </bean>

    <bean id="secureRemoteInvocationExecutor"
        class="org.apache.shiro.spring.remoting.SecureRemoteInvocationExecutor">
        <property name="securityManager" ref="securityManager"></property>
    </bean>

    <bean id="shiroFilter"
        class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <property name="securityManager" ref="securityManager"></property>
        <property name="loginUrl" value="/login.jsp"></property>
        <property name="successUrl" value="/success.jsp"></property>
        <property name="unauthorizedUrl" value="/unauthorized.jsp"></property>

        <property name="filterChainDefinitions">
            <value>
                /login.jsp = anon
                /** = authc
            </value>
        </property>
    </bean>
</beans>

里面用到了jbbcrealm的一个引用类，在类路径下，建立文件cn.taotao.bean.shiroRealm，实现接口org.apache.shiro.realm.Realm。

测试，可以PASS
