Spring Boot REST API 以格式显示响应结果

Question

我想以以下格式显示响应结果：

[
"author":"Author",
"status_code":"200"
"message":"GET",
"description":"Description..."
"data":{
    "id":"123",
    "name":""My Name",
    ...   : ...
}
]

但是我只显示每条数据结果如下：

[
  {
    "id":"123",
    "name":""My Name",
    ...   : ...
  }
]

这是显示响应结果的代码片段

控制器

 @GetMapping(value = "categorie")
    fun getAllFoodCategories(@Param(value = "key") key:String): ResponseEntity<List<Category>> {

        if (key==AppUtils.APY_KEY){
            var foodCategories: List<Category> = foodCategoryRespository.findAll()
            return if(!foodCategories.isEmpty()){
                foodCategories.forEach { v ->
                    run {
                        logger.info(v.toString())
                    }
                }
                ResponseEntity(foodCategories, HttpStatus.OK)
            }else{
                ResponseEntity(HttpStatus.NO_CONTENT)
            }

        }else{
            return ResponseEntity(HttpStatus.UNAUTHORIZED)
        }
        
    }

型号class

@Entity(name = "categories")
data class Category(
        @Id
        @Column(name = "id")
        val id: Int,
        @get: NotBlank
        @Column(name = "name")
        val name: String
)

谁能帮我解答一下，谢谢。

你不能return不同的元素作为一个列表，但是你可以return作为一个对象，它包含一个类别的列表。像这样：

{
"author":"Author",
"status_code":"200"
"message":"GET",
"description":"Description..."
"data":[
    {
        "id":"123",
        "name":""My Name",
        ...   : ...
    }
 ]
}

为此，创建如下模型：

data class MyResponse(
   val author: String,
   val statusCode: String,
   val message: String,
   val description: String,
   val data: List<Category>
)

然后 return 与：

fun getAllFoodCategories(@Param(value = "key") key:String): ResponseEntity<MyResponse> {...}
