springdoc-openapi 如何显示字符串数组作为响应

Question

网络上没有很好的示例说明如何使用 springdocs-openapi 库 (1.5.7) 获得以下输出。我希望获得以下输出：

[
  "A", "B", "C"
]

这是基于所提供示例的代码。

@Operation(summary = "")
    @ApiResponses(value = {
            @ApiResponse(responseCode = "200", description = "OK",
                    content = {@Content(mediaType = "application/json",
                            array = @ArraySchema(schema = @Schema(implementation = String.class)),
                            examples = {@ExampleObject("A"), @ExampleObject("B"), @ExampleObject("C")}
                    )})

这会导致以下输出

[
  "string"
]

上面列出的 ["A","B","C"] 输出如何通过 springdocs-openapi 库实现？

Answer 1

您使用的 @ExampleObject 不正确。 value 属性（如果您未指定任何内容，也是默认属性）采用示例有效负载的 JSON 序列化对象。

因此要得到["A", "B"]，你不需要多个@ExampleObject，而是你需要一个例子一个注释。

因此更新如下所示的代码应该会有帮助

@Operation(summary = "Some method")
@ApiResponses(value = {
    @ApiResponse(responseCode = "200", description = "OK", content = {
        @Content(
            mediaType = MediaType.APPLICATION_JSON_VALUE,
            array = @ArraySchema(schema = @Schema(implementation = String.class)),
            examples = {
                @ExampleObject("[\"A\", \"B\"]")
            }
        )
    })
})

下面显示的是上面代码的输出

要指定多个示例，应该有多个示例对象如下所示

@Operation(summary = "Some method")
@ApiResponses(value = {
    @ApiResponse(responseCode = "200", description = "OK", content = {
        @Content(
            mediaType = MediaType.APPLICATION_JSON_VALUE,
            array = @ArraySchema(schema = @Schema(implementation = String.class)),
            examples = {
                @ExampleObject(name = "Example 1", summary = "Summary 1", description = "Some desc", value = "[\"A\", \"B\"]"),
                @ExampleObject(name = "Example 2", summary = "Summary 2", description = "Some desc", value = "[\"C\", \"D\"]")
            }
        )
    })
})

注意：@ExampleObject 的name 属性用于在规范文件内部标识示例。

"responses": {
  "200": {
    "description": "OK",
    "content": {
      "application/json": {
        "schema": {
          "type": "array",
          "items": {
            "type": "string"
          }
        },
        "examples": {
          "Example 1": {
            "summary": "Summary 1",
            "description": "Some desc",
            "value": [
              "A",
              "B"
            ]
          },
          "Example 2": {
            "summary": "Summary 2",
            "description": "Some desc",
            "value": [
              "C",
              "D"
            ]
          }
        }
      }
    }
  }
}
