spring-mvc框架配置详解

1.引入必要的jar包

maven的pom文件引入以下：

<!-- Spring Web -->
<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-web</artifactId>
   <version>${spring.version}</version>
</dependency>
<!-- spring mvc-->
<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-webmvc</artifactId>
   <version>${spring.version}</version>
</dependency>
<!-- spring context-->
<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-context</artifactId>
   <version>${spring.version}</version>
</dependency>

2.web.xml 引入必要配置

a. applicationContext.xml 主要是我们需要注入的bean

b.监听器是必要的，ContextLoaderListener指定了IOC容器初始化的方法

c.DispatcherServlet则定义了mvc的相关内容，并配置拦截的url，如下面所示，所有.do结尾的请求，都会通过SpringMVC这个servlet进行处理,具体的相关mvc内容在spring-mvc.xml里面。

<!-- SpringMVC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>
<servlet>
   <servlet-name>spring-mvc</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>
</servlet>
<servlet-mapping>
   <servlet-name>spring-mvc</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>
<!-- End SpringMVC配置 -->

3.spring-mvc.xml 配置

<?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"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="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-4.1.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

    <!-- scan the package and the sub package -->
    <context:component-scan base-package="com.yhyw.erp.aftersales"/>

    <!-- don't handle the static resource -->
    <mvc:default-servlet-handler />

    <!-- if you use annotation you must configure following setting -->
    <mvc:annotation-driven />

    <!-- configure the InternalResourceViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          id="internalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/WEB-INF/jsp/" />
        <!-- 后缀 -->
        <property name="suffix" value=".jsp" />
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
    </bean>

    <!-- 对静态资源文件的访问-->
    <mvc:resources mapping="/images/**" location="/WEB-INF/images/" cache-period="31556926"/>
    <mvc:resources mapping="/js/**" location="/WEB-INF/js/" cache-period="31556926"/>
    <mvc:resources mapping="/css/**" location="/WEB-INF/css/" cache-period="31556926"/>

</beans>

4.applicationContext.xml 配置

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

</beans>
