Eclipse J2EE+Maven+Tomcat（Jetty）构建Spring MVC项目

一步一步的我们试着使用Eclipse J2EE+Maven+Tomcat（Jetty） 搭建留住的web开发平台 Spring MVC的方法。

工具：Eclipse J2EE，Maven，Tomcat

Eclipse J2EE+Maven+Tomcat（Jetty）：http://www.eclipse.org/downloads/

Maven 3.3.3：http://maven.apache.org/download.cgi

Tomcat 7.X：http://tomcat.apache.org/

1.安装基础环境：

没啥好说的，JDK，Eclipse，Maven，配置环境变量等。

2.打开Eclipse，做web开发，我们还需要安装一些插件。

Eclipse插件地址：Luna - http://download.eclipse.org/releases/luna  （安装Web,XML,Java EE and OSGI Enterprise Development）

3.将Maven和Eclipse关联起来。略

4.新建Maven web项目。

5.修改pom.xml文件，将编译级别，需要的jar等信息写入pom.xml文件。然后Alt+F5刷新项目。

6.补全源码文件夹信息 (目前只有src/main/resources)

7.设置部署集 删除无用的test文件夹。

8.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"><display-name></display-name><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><!-- Spring的log4j监听器 --><listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener><!-- 核心控制器 --><servlet><servlet-name>test</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet-mapping><servlet-name>test</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping></web-app>

9.配置Spring 的ApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 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/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"><mvc:annotation-driven /><context:component-scan base-package="com.*" /><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/" /><property name="suffix" value=".jsp" /></bean></beans>

10.编写controller类

import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller //该类是Controller@RequestMapping("/index.do") //映射页面上Action的路径     该路径+方法路径=页面路径public class IndexController {       @RequestMapping(params = "method=add") public String add() {System.out.println("success");return "success"; //跳转页面}}

11.编写页面

<html><body><form method="post"action="<%=request.getContextPath()%>/index.do?method=add">name:<input type="text" name="name" id="name"> age:<inputtype="text" name="age" id="age"> <input type="submit"value="Add"></form></body></html>

运行结果：
