SpringMVC中Consumer与Produces学习笔记

1. 内容类型，客户端通过Content-Type设置,对应Controller的consumes配置

   @RestController
   public class ConsumersController {
       /**客户端发送json数据
        * {
        *   "firstName":"yi",
        *   "lastName":"cj"
        * }
        */
       // Content-Type为application/json，接收json类型的请求
       @GetMapping(value = "/myConsumes", consumes = MediaType.APPLICATION_JSON_VALUE)
       public String applicationJsonView(@RequestBody MyData myData){
           log.info("json ====> {}", myData);
           return "myFormAgreedJsonView" ;
       }
      /**客户端发送xml数据
       * 
       * 
       *     yi
       *     cj
       * 
       */
       // Content-Type为application/json，接收xml类型的请求
       @GetMapping(value = "/myConsumes", consumes = MediaType.APPLICATION_XML_VALUE)
       public String applicationXmlView(@RequestBody MyData myData){
           
           log.info("xml ====> {}", myData);
           return "myFormAgreedXmlView" ;
       }
   }
   

2. 可接收内容类型，客户端通过Accept设置，对应Controller的produces配置

   @RestController
   public class ProducesController {
       // Accept 为application/json的处理器，用于产生json类型的返回值
       @ResponseBody
       @GetMapping(value = "/myProduces", produces = MediaType.APPLICATION_JSON_VALUE)
       public MyData returnJsonValue(){
           return getMyData() ;
       }
       // Accept为application/xml的处理器，用于产生xml类型的返回值
       @GetMapping(value = "/myProduces", produces = MediaType.APPLICATION_XML_VALUE)
       public MyData returnXmlValue(){
           return getMyData() ;
       }
       // 测试Accept为*/*, 通过produces指定返回值类型为json
       @GetMapping(value = "/myAcceptAll", produces = MediaType.APPLICATION_JSON_VALUE)
       public MyData acceptAll(){
           return getMyData() ;
       }
       private MyData getMyData(){
           MyData myData = new MyData() ;
           myData.setFirstName("yi");
           myData.setLastName("cj");
           return myData ;
       }
   }
   

3. Model实体对象

   @Data
   @XmlRootElement
   public class MyData {
       private String firstName ;
       private String lastName ;
   }
