注意，该文是基于Spring4而不是Spring boot，因而非零配置文件。

1、Server端 整体架构

项目名对应容器(Tomcat)部署项目的名字，从而访问根URI为：http://localhost:8080/<your-application-name>

2、Lib

commons-logging可以在http://commons.apache.org/proper/commons-logging/download_logging.cgi 下载

3、配置

web.xml

通过servlet-name配置，调用<servlet-name>-servlet.xml。

   
     
    
     springPoC1
        
    	
     
      rest
     	
     
      		org.springframework.web.servlet.DispatcherServlet	
     	
     
      1
     	
    	
    		
     
      rest
     		
     
      /*
     	
        
        
     
      index.html
         
     
      index.htm
         
     
      index.jsp
         
     
      default.html
         
     
      default.htm
         
     
      default.jsp
       
    
   

rest-servlet.xml

通过component-scan配置，调用AppConfig。

AppConfig.java (需是代码，实为配置)

package com.test;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.EnableWebMvc;/* * http://www.tuicool.com/articles/rA7Bfu * http://blog.csdn.net/leecho571/article/details/6559758 * http://www.tuicool.com/articles/j6nIzu * http://www.yiibai.com/spring_mvc/spring-mvc-4-restful-web-services-crud-example-resttemplate.html */@Configuration@ComponentScan("com.test")@EnableWebMvcpublic class AppConfig {	private String test = "";	private String tes1 = test;}

4、代码

GreetingController.java

package com.test;import java.util.concurrent.atomic.AtomicLong;import org.springframework.http.MediaType;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestBody;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.RestController;import org.springframework.web.util.UriComponentsBuilder;@RestController@RequestMapping("/service")public class GreetingController {	private static final String template="Hello,%s";    private final AtomicLong counter = new AtomicLong();     @RequestMapping("/greeting")    public void greeting(@RequestParam(value="name",defaultValue="World") String name){        System.out.println(counter.getAndIncrement() + String.format(template, name));    }        @RequestMapping(value = "/user1", method = RequestMethod.POST)    public String postUser(@RequestBody String param, UriComponentsBuilder ucBuilder) {    	System.out.println("Creating User " + param);    	return param;    	    }        @RequestMapping(value = "/{name}", method = RequestMethod.GET)    public String getGreeting(@PathVariable String name) {    	String result="Hello "+name;      	return result;    }    }

5、Client端 Lib

6、Client端 代码

SpringRestTestClient.java

import java.net.URI;import org.springframework.web.client.RestClientException;import org.springframework.web.client.RestTemplate;public class SpringRestTestClient {	public static final String REST_SERVICE_URI = "http://localhost:8080/springPoC1/service";		private static void listAllUsers(){		RestTemplate restTemplate = new RestTemplate();		String jsonParam = "{\"name\":\"Aiya\"}";		try {			URI uri = restTemplate.postForLocation(REST_SERVICE_URI+"/user1", jsonParam, String.class);			if (null != uri){				System.out.println("Location : "+uri.toASCIIString());			} else {				System.out.println("uri is null~");			}			String jsonResult = restTemplate.postForObject(REST_SERVICE_URI+"/user1", jsonParam, String.class);			System.out.println("testUser~" + jsonResult);		} catch (RestClientException e) {			e.printStackTrace();		}	}		public static void main(String[] args) {		listAllUsers();	}}

 7、Postman测试

安装使用见另一博文《》
