SpringMvc&Maven初級篇(一)

開發工具：Eclipse IDE for Java EE Developers
目標：使用SpringMvc框架和Maven配置，開發HelloWorld項目
步驟：
1.新建--Maven Project

2.配置eclipse:
右鍵項目，選擇Project Facets，點擊Convert to faceted from

更改Dynamic Web Module的Version為2.5。(3.0為Java7的)。如果提示錯誤，可能需要在Java Compiler設置Compiler compliance level 為1.6。或者需要在此窗口的Java的Version改成1.6。

點擊Further configuration available…，彈出Modify Faceted Project窗口此處是設置web.xml文件的路徑，我們輸入src/main/webapp。Generate web.xml deployment descriptor自動生成web.xml文件，推薦勾選。
設置部署程序集(Web Deployment Assembly)：

Add -> Java Build Path Entries -> Maven Dependencies -> Finish

設置完成效果圖

3.配置pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<context:component-scan base-package="com.myapps.controllers" />

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/WEB-INF/views/"/>

<property name="suffix" value=".jsp"/>

</bean>

</beans>

在WEB-INF下新建文件夾：views
在views文件夾下新建

helloworldPage.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>helloworldPage.jsp</title>

</head>

<body>

Hello,world.Welcome ${name} here.

</body>

</html>

新建包：com.myapps.controllers

在上面的包內新建類：HelloWorldController.java

package com.myapps.controllers;

import
org.springframework.stereotype.Controller;

import
org.springframework.web.bind.annotation.RequestMapping;

import
org.springframework.web.servlet.ModelAndView;

@Controller

public class
HelloWorldController {

@RequestMapping(value="/helloworld")

public ModelAndView helloWord() {

return new
ModelAndView("helloworldPage", "name", "hdh");

}

}

接著在webapp下新建index.htm(注意后綴是htm,因為如果是html的話，會和web.xml的<url-pattern>*.html</url-pattern>攔截的后綴名沖突，當然也可以新建index.jsp文件)

<!DOCTYPE html
PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type"
content="text/html;
charset=UTF-8">

<title>index.htm</title>

</head>

<body>

<a href="helloworld.html">hello,world(htm)</a>

</body>

</html>

最后，部署項目，然后啟動tomcat服務器，輸入http://localhost:8080/helloworld/index.htm
,點擊鏈接進行測試。這樣簡單的Hello,world入門就完成了。

有不足的地方，請指正，有不明白的地方可以交流，謝謝。
