rest full api使用方便能够很好的弱耦合，那么spring对rest full服务很好的支持。

依赖的jar：

    	
     
      org.springframework
     	
     
      spring-web
     	
     
      4.1.0.RELEASE
     
    
    	
     
      org.springframework
     	
     
      spring-webmvc
     	
     
      4.1.0.RELEASE
     
    

web.xml配置：

    	
     
      spring
     	
     
      org.springframework.web.servlet.DispatcherServlet
     	
     		
      
       contextConfigLocation
      		
      
       classpath:spring-mvc.xml
      	
     	
     
      1
     
    
    	
     
      spring
     	
     
      /
     
    
    	
     
      contextConfigLocation
     	
     
      classpath:spring-admin.xml
     
    
    	
     
      org.springframework.web.context.ContextLoaderListener
     
    
    	
     
      		org.springframework.web.util.IntrospectorCleanupListener
     
    

spring-mvc.xml：

rest api相关的控制层代码：

@RestController  @RequestMapping("/api")public class ApiController extends BaseController {	private Logger log = LoggerFactory.getLogger(ApiController.class);	@RequestMapping(value = "/{id}", method = RequestMethod.GET)	@ResponseBody	public Item get(@PathVariable String id, HttpServletRequest request) {		Item item = new Item();		item.setId(id);		item.setName("name");		return item;	}	@RequestMapping(method = RequestMethod.POST)	@ResponseBody	public void post(Item item, HttpServletRequest request) {		log.info("post item:{}", item.toString());	}	@RequestMapping(method = RequestMethod.PUT,consumes=MediaType.APPLICATION_JSON_VALUE,produces=MediaType.APPLICATION_JSON_VALUE)	@ResponseBody	public void put(@RequestBody Item item, HttpServletRequest request) {		log.info("put item:{}", item.toString());	}	@RequestMapping(value = "/{id}", method = RequestMethod.DELETE)	@ResponseBody	public void delete(@PathVariable String id, HttpServletRequest request) {		log.info("delete id:{}", id);	}}
