5.  右击项目->Maven->Update Project-OK，对项目生成项目结构
6.  双击项目下的pom.xml，将pom.xml内容改为如下：
    
        <?xml version="1.0" encoding="UTF-8"?>
         <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         </web-app>
8.  处理项目报错，右击项目->Properties->Java Build Path，在Source下添加项目的Resource文件夹，点击Add Folder，如下图所示
    
    ![3bvpwY5.png][]
    
    在search文件夹下，点击Create New Folder
    
    ![LrhJxDF.png][]
    
    在对话框输入/src/main/resources，点击Finish
    
    ![FPpOtcI.png][]
    
    点击OK完成文件夹创建
9.  修改JRE，选择Libraries，选择JRE System Library，点击Edit
    
    ![dOk5Oyk.png][]
10. 将JRE修改为系统默认JRE:
    
    ![6GxXOTT.png][]
11. 修改Dynamic Web Module版本，在项目是.settings文件夹下，双击`org.eclipse.wst.common.project.facet.core.xml`，将jst.web的version改为3.0
    
    ![w2VsXvl.png][]
12. 在resource下创建applicationContext.xml，文件内容如下：
    
        <?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"

        	<context:annotation-config />
        	
        	<context:component-scan base-package="com.elastic" />
          
        </beans>
13. 在resource下创建spring-mvc.xml，内容如下：
    
        <?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"

14. 在src/main/java创建包，然后对项目右击->Maven->Update Project
    
    ![fCp8Ctn.png][]
15. 对SpringMVC进行测试，在controller层创建类，具体代码如下：
    
        package com.elastic.controller;
        
        import org.springframework.stereotype.Controller;
        import org.springframework.web.bind.annotation.RequestMapping;
        
        @Controller
        @RequestMapping("/es")
        public class EsController {
        	
        	@RequestMapping("/elastic")
        	public void elastic(){
        		System.out.println("elastic");
        	}
        	
        }
16. 配置Tomcat，选择Window->Preferences->Server->Runtime Environments->Add，选择Tomcat路径和JRE
    
    ![XSFRLc6.png][]
17. 将项目添加到Tomcat，点击如下图处
    
    ![HUI016P.png][]
