通數據阿賈克斯

Question

到Spring MVC的控制器如何我normaly阿賈克斯 數據傳遞到MVC控制器動作現在在我的JS文件

$.ajax({ 
    type: "POST", 
    url:url, 
    data:  { 
      start_date: scheduler.getEvent(id).start_date, 
      end_date: scheduler.getEvent(id).end_date, 
      text: scheduler.getEvent(id).text, 
      userId: userId 
    }, 
    success:function(result){ 
     if(combo.getActualValue() != null){ 
      getUserEvents(id); 
     } 
     else{ 
      $.ajax({ 
       url:"/WebElanceSh/events", 
       success:function(result){ 
        json = result; 
        scheduler.parse(json, "json"); 
       } 
      }); 
     } 
    } 
}); 

，並在我的控制器

@RequestMapping(value = "events/add/", method = RequestMethod.POST) 
public void addEvent(@RequestBody String start_date, 
        @RequestBody String end_date, 
        @RequestBody String text, 
        @RequestBody Integer userId){ 
    Event event = new Event(text,start_date,end_date); 

    if(userId == -1){ 
     TestData.getInstance().AddEvent(-1, event); 

    } 
    else { 
     TestData.getInstance().AddEvent(userId, event); 

    } 

} 

但是我有始終有 加載資源失敗：服務器響應的狀態爲415（不支持的介質類型）

模擬與ajax請求匹配的對象，然後使用它作爲請求參數：＃

public class MyCommandObject { 
    private Date start_date; 
    private Date end_date; 
    private String text; 
    private Integer userId; 

    /** Constructor wihtout parameter needed. */ 
    public MyCommandObject() {} 

    Getter and Setter 
} 


@RequestMapping(value = "events/add/", method = RequestMethod.POST) 
public void addEvent(@RequestBody MyCommandObject command){ ... }
