java - 如何在 Kotlin 中使用 Swagger @ApiResponses 注解？

Question

如何将以下 Swagger 注解从 Java 转换为 Kotlin？

 @ApiResponses(value = { @ApiResponse(code = 200, message = "Given admin user found"),
            @ApiResponse(code = 404, message = "..."),
            @ApiResponse(code = 500, message = "..."),
            @ApiResponse(code = 400, message = "..."),
            @ApiResponse(code = 412, message = "...") })

这不起作用:

@ApiResponses(value = listOf( 
        ApiResponse(code = 200, message = "..."),
        ApiResponse(code = 404, message = "..."),
        ApiResponse(code = 500, message = "..."),
        ApiResponse(code = 400, message = "..."),
        ApiResponse(code = 412, message = "...") ))

错误是:

Type inference failed. Expected type mismatch: inferred type is List but ApiResponse was expected

当我只使用一个 @ApiResponse 而不是 listOf() 时它可以工作，但我必须定义更多 @ApiResponse(s) .

我使用 Swagger 2.5.0

如 the Kotlin Language Reference 中所述:

If the value argument [of an Annotation] in Java has an array type, it becomes a vararg parameter in Kotlin

所以，为了让你的例子工作，你需要这样说:

@ApiResponses(
    ApiResponse(code = 200, message = "..."),
    ApiResponse(code = 404, message = "..."),
    ApiResponse(code = 500, message = "..."),
    ApiResponse(code = 400, message = "..."),
    ApiResponse(code = 412, message = "...")
)
