SpringMVC框架是Java开发中最常用的开发框架了，网上关于其配置讲解也是数不胜数, 这次我也整理出来一个最初级的，引用jar包最少的纯净版SpringMVC框架（注: 无数据库配置,下次再加）;

新建 maven-web 项目并引入jar包 pom.xml： 

    	
     
      4.0.0
     	
     
      com.gy.spring
     	
     
      spring-mvc
     	
     
      war
     	
     
      0.0.1-SNAPSHOT
     	
     
      spring-mvc Maven Webapp
     	
     
      http://maven.apache.org
     	
     		
      
       2.6
      		
      
       4.3.13.RELEASE
      	
     	
     		
      			
       			
       				
        
         org.springframework
        				
        
         spring-framework-bom
        				
        
         ${spring.version}
        				
        
         pom
        				
        
         import
        			
       		
      	
     	
     		
      			
       
        junit
       			
       
        junit
       			
       
        4.12
       			
       
        test
       		
      		
      			
       
        org.springframework
       			
       
        spring-webmvc
       		
      		
      			
       
        org.springframework
       			
       
        spring-test
       		
      		
      		
      			
       
        log4j
       			
       
        log4j
       			
       
        1.2.17
       		
      		
      		
      		
      					
      		
      			
       
        javax.servlet
       			
       
        jstl
       			
       
        1.2
       		
      		
      		
      			
       
        com.fasterxml.jackson.core
       			
       
        jackson-databind
       			
       
        2.9.4
       		
      				
      		
      			
       
        commons-fileupload
       			
       
        commons-fileupload
       			
       
        1.3.3
       		
      	
     	
     		
      
       spring-mvc
      		
      		
      			
       				
        
         org.eclipse.jetty
        				
        
         jetty-maven-plugin
        				
        
         9.4.8.v20171121
        			
       		
      	
     
    

2, web.xml: （DispatcherServlet, HTTP请求入口配置）

    
    	
     	
     
      Spring MVC WEB
     		
     	
     		
      
       contextConfigLocation
      		
      
       classpath:spring-mybatis.xml
      	
     	
     		
      
       org.springframework.web.context.ContextLoaderListener
      	
     		
     	
     		
      
       springMVC
      		
      
       org.springframework.web.servlet.DispatcherServlet
      		
      		
      			
       
        contextConfigLocation
       			
       
        classpath:spring-mvc.xml
       		
      		
      
       1
      	
     	
     		
      
       springMVC
      		
      		
      
       /
      	
     
    

根据web.xml配置可以知道文件 spring-mvc.xml 来管理数据请求及视图输出；

3，配置 spring-mvc.xml :

到这视图controller部分已经可以启动使用了,不过继续把下面的写完再一块来看；

4, 根据 web.xml 配置 Spring业务(一般为数据库,其他需要整合的框架等)  spring-mybatis.xml (名字随便起，必须与web.xml中加载的一致)： 

5, 先来看看项目结构：

项目结构就是这样，现在再来写个简单的controller :

package com.gy.spring.mvc.controller;import java.text.SimpleDateFormat;import java.util.Date;import java.util.HashMap;import javax.servlet.http.HttpServletResponse;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.util.FileCopyUtils;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.multipart.MultipartFile;import com.gy.spring.mvc.service.HelloService;@Controller@RequestMapping("/hello")public class HelloController {	private static Log logger = LogFactory.getLog(HelloController.class);		@Autowired	private HelloService helloService;	@RequestMapping("")	public String index() {		return "index";	}		@ResponseBody	@RequestMapping("hello")	public Object hello() {		return helloService.hello();	}		@ResponseBody	@RequestMapping("hello/{id}")	public Object hello(@PathVariable("id")int id) {		SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");		HashMap
    
      map = new HashMap<>();		map.put("id", id);		map.put("author","geYang");		map.put("data",sf.format(new Date()));		logger.info(map);		return map;	}		@RequestMapping(value="upload",method=RequestMethod.POST)	public void upload(@RequestParam("file")MultipartFile file,HttpServletResponse response) throws Exception {		if(!file.isEmpty()) {			logger.info("file [name:"+file.getOriginalFilename()+", size:"+file.getSize()+", fileName:"+file.getName()+", type:"+file.getContentType()+"");			FileCopyUtils.copy(file.getInputStream(),response.getOutputStream());			//上传的两种方法://			FileUtils.copyInputStreamToFile(file.getInputStream(), new File("E:/notes/IMGS/image/xx.jpg"));//			file.transferTo(new File("E:/notes/IMGS/image/xxx.jpg"));		}	}}
    

service 接口:

package com.gy.spring.mvc.service;public interface HelloService {	String hello();}

service 实现:

package com.gy.spring.mvc.service.impl;import org.springframework.stereotype.Service;import com.gy.spring.mvc.service.HelloService;@Servicepublic class HelloServiceImpl implements HelloService {	@Override	public String hello() {		return "Hello World!";	}}

再来个jsp页面(该jsp再view目录下)：

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%>
    	
MVC的核心思想是业务数据的抽取和业务数据的呈现相分离
	
    
		
     		
     	
    

注意,要使用 @ResponseBoday 来返回JSON 一定要引用 pom.xml 中的:

    		
    			
     
      com.fasterxml.jackson.core
     			
     
      jackson-databind
     			
     
      2.9.4
     		
    

否则会报错的; 到这已经可以运行项目啦

现在配置就已经完成一部分啦，下来就看看日志输出： log4j.properties (注意引用上面的Jar包哦)

# set log levelslog4j.rootLogger = debug , stdout , D , E#输出到控制台log4j.appender.stdout = org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target = System.out#输出INFO级别以上的日志log4j.appender.stdout.Threshold = INFOlog4j.appender.stdout.layout = org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{1}:%L - %m%nlog4j.appender.D = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.D.File = E:/logs/log.loglog4j.appender.D.Append = true#输出DEBUG级别以上的日志log4j.appender.D.Threshold = DEBUGlog4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%nlog4j.appender.E = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.E.File = E:/logs/debug.loglog4j.appender.E.Append = true#输出ERROR级别以上的日志log4j.appender.E.Threshold = ERRORlog4j.appender.E.layout = org.apache.log4j.PatternLayoutlog4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%nlog4j.appender.E = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.E.File = E:/logs/debug.loglog4j.appender.E.Append = true

接下来就是最关键最重要的 jUint 与 spring 的整合啦(包不能忘)：

    			
     
      junit
     			
     
      junit
     			
     
      4.12
     			
     
      test
     		
    		
    			
     
      org.springframework
     			
     
      spring-webmvc
     		
    		
    			
     
      org.springframework
     			
     
      spring-test
     		
    

测试基类：

package com.gy.spring.mvc;import java.text.SimpleDateFormat;import java.util.Date;import org.junit.Before;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.context.web.WebAppConfiguration;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations={"classpath:spring-mvc.xml","classpath:spring-mybatis.xml"})@WebAppConfigurationpublic class SpringTest {	public static SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");	@Before	public void setUp() throws Exception {		System.out.println("测试时间: " + sf.format(new Date()));	}	}

其他测试类继承该类，进行测试：

package com.gy.spring.mvc.service;import org.junit.Test;import org.springframework.beans.factory.annotation.Autowired;import com.gy.spring.mvc.SpringTest;public class HelloServiceTest extends SpringTest {	@Autowired	private HelloService helloService;		@Test	public void testHello() {		System.out.println(helloService.hello());	}}

现在就可以进行开发啦， 简单的SpringMVC框架就已经搭建成功啦；

SSM集成已经完善，项目地址： 

后续还会有更多的框架集成配置；
