獲取「錯誤不支持的媒體類型」，同時綁定彈簧mvc控制器的JSON數據

Question

我使用基於Jquery的Jstree庫捕獲分層數據。數據是JSON格式，我想捕獲並將此數據綁定到我的bean類JstreeJson.java）。這裏是我到目前爲止已經試過..

Ajax調用：

function getJSON() {  
       var jstree = $('#jstree1').jstree(true).get_json('#', {flat:true}); 
       console.log(JSON.stringify(jstree)); 
       $.ajax({   
        type:"POST", 
        url:"createObjective", 
        data : { jstree: jstree },      
        dataType :"json", 
        success : function(result) { 
         console.log(jstree); 
        console.log(result); 
       }, 
       error: function(jqXHR, textStatus, errorThrown) { 
        console.log(jqXHR); 
        console.log(textStatus, errorThrown); 
       } 
      }); 

     } 

的console.log輸出：

[{"id":"j1_1","text":"Simple root node","icon":true,"li_attr":{"id":"j1_1"},"a_attr":{"href":"#","id":"j1_1_anchor"},"state":{"loaded":true,"opened":false,"selected":false,"disabled":false},"data":{},"parent":"#"}] 

控制器

@RequestMapping(value="/createObjective",method=RequestMethod.POST) 
public @ResponseBody String createObjective(@RequestBody JstreeJson jstree) 
{ 
    System.out.println(jstree); 
    return "done"; 
} 

Bean類

public class JstreeJson 
{ 
    private String id; 
    private String text; 
    private String parent; 
    // getters and setter 
} 

我曾嘗試加入消耗和接頭，但它沒有對我的輸出

@RequestMapping(value="/createObjective",method=RequestMethod.POST,consumes="application/json",headers = "content-type=application/x-www-form-urlencoded") 

Answer 1

任何影響試試這個@RequestMapping： -

@RequestMapping(value="/createObjective" method = RequestMethod.POST,consumes= {"application/json;charset=UTF-8"}, produces={"application/json;charset=UTF-8"}) 
public @ResponseBody String createObjective(@RequestBody JstreeJson jstree) 
{ 
    System.out.println(jstree); 
    return "done"; 
} 

或者你可以保持@RequestMapping簡單如下：

@RequestMapping(value="/createObjective") 

Spring會根據請求處理@RequestMapping屬性的其餘部分。
