在 Swagger API 响应中设置对象列表

Question

我想在使用 Swagger 的 API 响应中发送对象列表。

@ApiResponse(code = 200, message = ApiResponseMessages.ITEM_FETCHED, 
response = "")

我有一堂课——

class Item{
   int id;
   String item_name;
}

我想要这样的回应 -

{
    {
       "id" : 0,
       "item_name" : ""
    }
    {
       "id" : 0,
       "item_name" : ""
    }
    {
       "id" : 0,
       "item_name" : ""
    }
}

我怎样才能做到这一点。任何帮助，将不胜感激。

Answer 1

您还可以像这样设置ApiReponse：

@ApiResponse(code = 200, message = ApiResponseMessages.ITEM_FETCHED,
             response = Item.class, responseContainer = "List"
            )

它会返回：

[
    {
       "id" : 0,
       "item_name" : ""
    },
    {
       "id" : 0,
       "item_name" : ""
    },
    {
       "id" : 0,
       "item_name" : ""
    }
]

对于新包：io.swagger.v3.oas.annotations.responses.ApiResponse

你需要这样做（带@ArraySchema注释）：

@ApiResponse(responseCode = "200", description = "",
            content = {@Content(
                mediaType = "application/json",
                array = @ArraySchema(schema = @Schema(implementation = Bar.class))
            )}
)

Answer 3

您可以使用responseContainer = "List"如下：

@ApiOperation(value = "retrieve items", response = Item.class, responseContainer = "List")
