Eclipse中Maven+Spring3.2.8+SpringMVC HelloWorld项目

亲测可用

准备工作
确保你的eclipse已经整合M2E插件，即新建项目有Maven选项。不要用Eclipse自带的Maven，在设置中将本地Maven添加进去。
这里写图片描述

1.建立项目

在Eclipse中新建一个Maven项目，Select Archetype时选择maven-archetype-webapp。
修改pom.xml，最终结果如下：

<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/maven-v4_0_0.xsd">

                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                </configuration>
            </plugin>
        </plugins>
        <finalName>test</finalName>
    </build>
</project>

此时项目即设置为servlet3.0的web项目。

重启eclipse，更新项目（右键点项目-maven-update project）。

下面的部分是从网上复制的，不想打了。其中add source folder可以换成在build path的source选项卡中修改。

2.配置Maven项目

接下来就需要更改好多配置了。

2.1 添加Source文件夹
接下来需要添加src/main/java，src/test/java ，src/test/resources三个文件夹。右键项目根目录点击New -> Source Folder，
建出这三个文件夹。注意不是建普通的Folder，而是Source Folder。
这里写图片描述

2.2 更改class路径
右键项目，Java Build Path -> Source
下面应该有4个文件夹。src/main/java，src/main/resources，src/test/java ，src/test/resources。
双击每个文件夹的Output folder，选择路径。
src/main/java，src/main/resources，选择target/classes;
src/test/java ，src/test/resources, 选择target/test-classes;
选上Allow output folders for source folders.

——————————————–分割线—————————————————–
此时Maven Web项目基本骨架已经完成，下面要进行的就是开发部分了。
首先，要修改Web.xml文件（位于webapp/WEB-INF下），最终结果如下：

<?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">



  <display-name>Archetype Created Web Application</display-name>
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:spring-config.xml
        </param-value>
    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <!-- Spring配置文件结束 -->


    <filter>
        <filter-name>Encoding</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>Encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


    <!-- Spring MVC配置开始 -->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>
    <!-- Spring MVC配置结束-->
</web-app>

其中涉及的Spring和SpringMVC设置均为个人喜好，你可以根据自己的习惯更改。其中classpath:spring-config.xml 和classpath:spring-servlet.xml分表指向Spring配置文件和SrpingMVC配置文件的位置，本文中即为两者都在ClassPath下。如果想要跨模块引用，则需将classpath：xxx改为classpath*:XXX。
在src/main/resources下建立classpath:spring-config.xml 文件

<?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"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:p="http://www.springframework.org/schema/p"
    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
            http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
    <context:annotation-config />
    <context:component-scan base-package="com.zp.test" >
        <!-- <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> -->
    </context:component-scan>
</beans>

代码就不多解释了，不懂的再看看spring的基础配置。
在src/main/resources下建立classpath:spring-servlet.xml 文件

<?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:p="http://www.springframework.org/schema/p" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/util
        http://www.springframework.org/schema/util/spring-util-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" >

         <context:annotation-config />    
    <context:component-scan base-package="com.zp.test.controller">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

        <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:order="3">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="contentType" value="text/html"/>      
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

此时Spring和SpringMVC配置已经完成。
然后在src/main/java/YouPackage下建立controller，service，service.impl三个包。
在service包中添加HelloWorldService接口

package com.zp.test.service;
    public interface HelloWorldService {
         public String getNewName(String userName); 
}

service.impl中添加HelloWorldServiceImpl类

package com.zp.test.service.impl;

import org.springframework.stereotype.Service;

import com.zp.test.service.HelloWorldService;

@Service
public class HelloWorldServiceImpl implements HelloWorldService {

    @Override
    public String getNewName(String userName) {
        return "hello spring!"+userName;
    }

}

此服务的功能就是将传过来的参数前面加上Hello spring。
controller中添加HelloWorldController类

package com.zp.test.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import com.zp.test.service.HelloWorldService;

@Controller
public class HelloWorldController {
     @Autowired
     private HelloWorldService helloWorldService;


     @RequestMapping("helloworld")
     public String getNewName(@RequestParam("userName") String userName, HttpServletRequest request){

            String newUserName = helloWorldService.getNewName(userName);

            request.setAttribute("newUserName", newUserName);

            return "helloworld";

     }

}

控制器作用是将httprequest传过来的参数通过HelloWorldService加上hello spring后返回给helloworld.jsp，由其显示出来。
后台部分完成。
前台：
index.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>
<form action="helloworld.html" method="post">

请输入姓名：<input type="text" name="userName" />

<input type="submit" value="提交" />

<br />

</form>
</body>
</html>

helloworld.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><%=request.getAttribute("newUserName")%></h1>
</body>
</html>

两者都在webapp根目录下建立。
项目完成，run on service或者打包发布到本地tomcat即可运行。
