傑克遜：與陣列無效JSON形式對象

Question

我有此代碼

彈簧的context.xml

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> 
<property name="messageConverters"> 
     <list> 
      <ref bean="jsonMessageConverter"/> 
     </list> 
    </property> 
</bean> 

<!-- Configure bean to convert JSON to POJO and vice versa --> 
<bean id="jsonMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> 
    <property name="prefixJson" value="false"/> 
    <property name="supportedMediaTypes" value="application/json"/> 
</bean> 

JsonResponse.java

/*

* To change this template file, choose Tools | Templates 
* and open the template in the editor. 
*/ 
package com.globe.egg.ggrocery.item.model; 

/** 
* 
* @author Farhan Sharief 
*/ 
public class JsonResponse { 
private int status; 
private Object body; 

public int getStatus() { 
    return status; 
} 

public void setStatus(int status) { 
    this.status = status; 
} 

public Object getBody() { 
    return body; 
} 

public void setBody(Object body) { 
    this.body = body; 
} 

public static JsonResponse createResponse(int status, Object body) { 
    JsonResponse response = new JsonResponse(); 
    response.setStatus(status); 
    response.setBody(body); 
    return response; 
} 
} 

和我的控制器

@RequestMapping(value = "/list", 
method = RequestMethod.GET) 
public @ResponseBody JsonResponse getCategories() { 
    return JsonResponse.createResponse(SUCCESS.getStatus(), categoryService.getCategories()); //returns a List<Category> 
} 

我在等待

{ 
"status": 200, 
"body": [ 
    { 
     "categoryId": 1, 
     "categoryName": "basket", 
     "subCategory": "NONE", 
     "version": 1 
    }, 
    { 
     "categoryId": 2, 
     "categoryName": "Cosmetics", 
     "subCategory": "NONE", 
     "version": 1 
    } 
] 
} 

，但我發現

{ 
    status: 200 
    body: [2] 
     0: { 
      categoryId: 1 
      categoryName: "basket" 
      subCategory: "NONE" 
      version: 1 
      } 
     1: { 
      categoryId: 2 
      categoryName: "Cosmetics" 
      subCategory: "NONE" 
      version: 1 
     } 

} 

我的問題是，JSON有沒有雙引號和身體結構是無效的。它有[2]。

原來，這是因爲我的高級休息客戶端的看法。
