springMVC环境搭建

1.在myeclipse上建立web projectproject选择加入mavenproject add maven support

2.选择建立web.xml文件,名字随意

3.选择standard Maven JEEproject structure

4.点击取消两个环境依赖

5.之后形成例如以下文件夹（由于我这个文件夹是git文件夹所以有一些版本号控制信息）
会有报错信息是由于没有jsp和servlet的jar包

6.增加jsp和servlet的jar包

<span style="white-space:pre">	</span><!-- jstl begin-->
  	<dependency>
		<groupId>taglibs</groupId>
		<artifactId>standard</artifactId>
		<version>1.1.2</version>
		<type>jar</type>
	</dependency>
	<dependency>
		<groupId>javax.servlet</groupId>
		<artifactId>jstl</artifactId>
		<version>1.2</version>
		<type>jar</type>
	</dependency>
	<!-- jstl end-->
	
	<!-- servlet,jsp begin-->
	<dependency>
		<groupId>javax.servlet</groupId>
		<artifactId>servlet-api</artifactId>
		<version>2.5</version>
		<scope>provided</scope>
	</dependency>
	<dependency>
		<groupId>javax.servlet.jsp</groupId>
		<artifactId>jsp-api</artifactId>
		<version>2.1</version>
		<scope>provided</scope>
	</dependency>
	<dependency>
		<groupId>javax.servlet</groupId>
		<artifactId>javax.servlet-api</artifactId>
		<version>3.1.0</version>
		<scope>provided</scope>
	</dependency>
	<dependency>
		<groupId>javax.servlet.jsp</groupId>
		<artifactId>jsp-api</artifactId>
		<version>2.2</version>
		<scope>provided</scope>
	</dependency>
	<!-- servlet,jsp end-->

报错信息解决

7.添加springmvc的jar包和日志包

<!-- springmvc begin -->
	<dependency>

		<version>4.0.8.RELEASE</version>

	</dependency>
	<!-- LOGGING end -->

8.web.xml中添加springMVC的配置和监听

<?xml version="1.0" encoding="UTF-8"?>
