Spring MVC 配置文件

一、web.xml

　　

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  
  <!-- 前端控制器 -->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>    
  <servlet-mapping>
      <servlet-name>springMVC</servlet-name>
      <url-pattern>/</url-pattern>
  </servlet-mapping>
  
  <!-- 中文乱码解决方案 -->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>utf-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

二、springMVC-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:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation=" 
           http://www.springframework.org/schema/beans 
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
           http://www.springframework.org/schema/context 
           http://www.springframework.org/schema/context/spring-context-3.0.xsd
           http://www.springframework.org/schema/mvc 
           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
           http://www.springframework.org/schema/aop 
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd" default-autowire="byName">
    <!--  传统映射支持做法 
     HandlerMapping 
    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
     HandlerAdapter   
    <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
    -->
    <!-- 默认的注解映射支持 不推荐 -->
    <!--  
    <mvc:annotation-driven/>
    -->
    <!-- 基于注解 映射类 -->
    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
        <!-- 拦截器  静态资源不会被拦截-->
        <property name="interceptors">       
            <list>       
                <bean class="com.mvc.demo.SysInteceptor"></bean>      
            </list>       
         </property> 
    </bean>
    <!-- 基于注解 映射方法 -->
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <!-- 转换器 -->
        <property name="messageConverters">
            <list>
                <!-- 配置一下对json数据的转换 -->
                <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean>
            </list>
        </property>
    </bean>
    <!-- 自动扫描的包名  -->
    <context:component-scan base-package="cn.javass.chapter2.web"></context:component-scan>
    
    
    
    <!-- 
    ③：对模型视图名称的解析，即在模型视图名称添加前后缀
    InternalResourceViewResolver默认的就是JstlView所以这里就不用配置viewClass了 
    -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>        
</beans>

三、<mvc:annotation-driven/>

　　

   <!-- 注解请求映射  -->  
   <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">          
    <property name="interceptors">  
        <list>    
            <ref bean="logNDCInteceptor"/>   <!-- 日志拦截器，这是你自定义的拦截器 -->  
            <ref bean="myRequestHelperInteceptor"/>   <!-- RequestHelper拦截器，这是你自定义的拦截器-->   
            <ref bean="myPermissionsInteceptor"/>  <!-- 权限拦截器，这是你自定义的拦截器-->   
            <ref bean="myUserInfoInteceptor"/>  <!-- 用户信息拦截器，这是你自定义的拦截器-->   
        </list>          
    </property>          
</bean>     
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  
    <property name="messageConverters">    
        <list>    
            <ref bean="byteArray_hmc" />    
            <ref bean="string_hmc" />    
            <ref bean="resource_hmc" />    
            <ref bean="source_hmc" />    
            <ref bean="xmlAwareForm_hmc" />    
            <ref bean="jaxb2RootElement_hmc" />    
            <ref bean="jackson_hmc" />    
        </list>    
    </property>    
</bean>    
<bean id="byteArray_hmc" class="org.springframework.http.converter.ByteArrayHttpMessageConverter" /><!-- 处理.. -->
