SpringMVC 项目框架的搭建（javaweb项目）

1、首先创建一个java的mavenweb项目，即选择war包。

2、由于刚创建的web工程缺少web.xml等相关的文件，所以会出现一系列的错误，可以用两种方法去改掉报错。

第一种：手动添加其他java web项目下的下图文件夹（需要包含web.xml文件）放到项目的webapp的文件夹下面

第二种：在项目上右键，最后一个Properties选项，选择Projects  Facets，如下图，在Dynamic Web Module选项上勾选Apply会出现下面的Futher Configuration available的链接，点进去

点进去之后会出现下面的弹出框，上面一个就是项目名不用改，下面一个改成src/main/webapp,然后确定，最后将Dynamic Web Module改成3.0在勾选上确定即会自动在webapp的目录下面创建方法一中的两个文件和其中的web.xml文件。

4、更改pom.xml文件，添加需要的依赖，这里我用的是一个总结版的pom直接放进去

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">

	</dependencies>
</project>

4、添加spring.xml和springmvc的文件
这里简单配置一下识别注解，没有很完善的功能

spring.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:aop="http://www.springframework.org/schema/aop"
	xmlns:context="http://www.springframework.org/schema/context"
	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-4.3.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">

	<context:component-scan base-package="com.iflytek">
		<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
	
</beans>

springmvc.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.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
	
	<context:component-scan base-package="com.iflytek">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
	
</beans>

5、在web.xml中做相应的配置，将以上Spring.xml和springmvc.xml文件加载到tomcat中，代码如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="WebApp_ID" version="3.0">

	<!-- spring配置文件的路径 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml</param-value>
	</context-param>
	
	<servlet>
		<servlet-name>dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

</web-app>

6、编写对应的Controller文件和jsp文件开始你的项目，这里只用了HomeCntroller.java文件和home.jsp文件

HomeController.java

package com.iflytek.controller;

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

@Controller
public class HomeController {

	@RequestMapping("/home")
	public String goHome() {
		return "/WEB-INF/jsp/home.jsp";
	}
}

home.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>Insert title here</title>
</head>
<body>
	<h1>这里是Home</h1>
</body>
</html>

最终在浏览器中的结果如下
