spring mvc常用配置

一：新建web工程，spring001

忽略

二：添加springframework依赖jar包

三：修改web.xml

[html] view plaincopy

1. <servlet>  
2.     <servlet-name>springMVC</servlet-name>  
3.     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
4.     <init-param>  
5.         <param-name>contextConfigLocation</param-name>  
6.         <param-value>/WEB-INF/config/springMVC.xml</param-value>  
7.     </init-param>  
8.     <load-on-startup>1</load-on-startup>  
9. </servlet>  
10.   
11. <servlet-mapping>  
12.     <servlet-name>springMVC</servlet-name>  
13.     <url-pattern>/</url-pattern>  
14. </servlet-mapping>  

默认DispatcherServlet会加载WEB-INF/[DispatcherServlet的Servlet名字]-servlet.xml配置文件，

本示例为WEB-INF/springMVC-servlet.xml

默认路径为WEB-INF下,也可修改为如下配置

[html] view plaincopy

1. <init-param>  
2.     <param-name>contextConfigLocation</param-name>  
3.     <!-- <param-value>classpath:conf/springMVC.xml</param-value>  -->  
4.     <!-- <param-value>classpath:/conf/springMVC.xml</param-value> -->  
5.     <!-- <param-value>classpath*:/conf/springMVC.xml</param-value>  -->  
6.     <!-- 以上三种形式也可以 -->  
7.     <param-value>classpath:conf/springMVC.xml</param-value>  
8. </init-param>  

四：添加springMVC配置文件

[html] view plaincopy

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <beans xmlns="http://www.springframework.org/schema/beans"  
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"  
4.     xmlns:context="http://www.springframework.org/schema/context"  
5.     xmlns:mvc="http://www.springframework.org/schema/mvc"  
6.     default-lazy-init="true"  
7.     xsi:schemaLocation="    
8.     http://www.springframework.org/schema/beans     
9.     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd    
10.     http://www.springframework.org/schema/context    
11.     http://www.springframework.org/schema/context/spring-context-3.0.xsd    
12.     http://www.springframework.org/schema/mvc    
13.     http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd    
14.     ">  
15.   
16.     <!-- 默认扫描的包路径 -->  
17.     <context:component-scan base-package="com.itmyhome" />  
18.   
19.     <!-- 添加注解驱动 -->  
20.     <mvc:annotation-driven />  
21.   
22.     <!-- 定义跳转的文件的前后缀 -->  
23.     <bean id="viewResolver"  
24.         class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
25.         <property name="prefix" value="/" />  <!-- 默认放在WebRoot下 -->  
26.         <property name="suffix" value=".jsp" />   
27.     </bean>  
28. </beans>
