java - 按照预期从 Java Restful API 获取 JSON 格式的数据

Question

现在的输出是:

{
 "Product_Type":
    "[{\"active\":true,\"description\":\"ALL IN ONES\",\"id\":2},     
      {\"active\":true,\"description\":\"ACCESSORIES\",\"id\":1}]",
 "Product_Brand":
    "[{\"active\":false,\"brand\":\"101 DALMATIANS\",\"id\":1}]"
}

预期是:

{
 "Product_Type":
    [{"active":true,"description":"ALL IN ONES","id":2},     
      {"active":true,"description":"ACCESSORIES","id":1}],
 "Product_Brand":
    [{"active":false,"brand":"101 DALMATIANS","id":1}]"
}

我有下面的restful api 代码，它返回json 数据。

Code:
@GET
@Produces(MediaType.APPLICATION_JSON)
@Path("brand")
public String getProductBrand() {       
    return attributeMasterService.getProductBrand() + 
            attributeMasterService.getProductType();        
}   

输出:

[{"active":false,"brand":"101 DALMATIANS","id":1}]      
[{"active":true,"description":"ACCESSORIES","id":1},     
{"active":true,"description":"ALL IN ONES","id":2}]

我需要帮助来获取下面提到的格式的数据。

基本上我需要将文档名称附加到数组中。

[
Product_Brand:
[    {"active":false,"brand":"101 DALMATIANS","id":1}],
Product_Type:
[    {"active":true,"description":"ALL IN ONES","id":2},     
     {"active":true,"description":"ACCESSORIES","id":1}]
]  

您能帮我构建上述结果吗？

谢谢

我建议您使用 JSON API 并使用它传递 DTO 对象。您需要定义一个 DTO 类，例如:

    public class A { 
        List<ProductBrand> brands; 
        List<ProductType> types; 

        //getter and setter methods
    }

然后创建该实例并设置其字段。将此类转换为 JSON 并返回它可以解决您的问题。
