快速搭建spring mvc

1.导包

commons-logging-1.1.3.jar

spring-aop-4.1.1.RELEASE.jar

spring-beans-4.1.1.RELEASE.jar

spring-context-4.1.1.RELEASE.jar

spring-core-4.1.1.RELEASE.jar

spring-expression-4.1.1.RELEASE.jar

spring-web-4.1.1.RELEASE.jar

spring-webmvc-4.1.1.RELEASE.jar      

2.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
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_3_0.xsd"> <!-- spring mvc容器和servlet的定义 -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 这里的参数如果不配置，则默认查找web-inf下的{servlet-name}-servlet.xml文件 -->
<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>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

说明：<param-value>classpath:spring-mvc.xml</param-value>这段配置说明在容器启动后会加载src目录下spring-mvc.xml配置文件

3.配置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:context="http://www.springframework.org/schema/context"
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"> 
<context:component-scan base-package="com.ln.baseframe.*.controller"/>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>

</beans>

4.创建Controller，Controller需在spring-mvc.xml里所配置的com.ln.baseframe.*.controller包下

package com.ln.baseframe.common.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping(value="common/index")
public class IndexController {

@RequestMapping(value="index",method=RequestMethod.GET)
public String index(){
return "common/index";
}
}

说明：再WEB-INF下面创建views文件夹，views下创建common文件夹，common下创建index.jsp

最后，启动项目访问http://localhost:8080/项目名/common/index。
