将Swagger UI和ApiResponses批注与Java Spring端点一起使用时，如何干燥?

问题描述

我喜欢Swagger，因为它使您的api非常用户友好.我使用Swagger注释，例如

I like Swagger because it makes your apis very user friendly. I use Swagger annotations like

• @ApiParam
• @ApiResponse | @ApiResponses
• @ApiOperation
• 其他

在端点上，查询参数，请求参数，请求正文等.

On endpoints, query params, request params, request body and so on.

我喜欢保持我的POJO类整洁，总的来说，我会尽力遵循DRY规则，但是当我大摇大摆时，我发现自己不断重复重复如下图所示

I like to keep my POJO classes clean and in general I try my best to follow DRY rule however, when it comes to swagger I noticed that I keep repeating myself over and over as shown below

@ApiOperation(value = "Retrieve object by id")
@ApiResponses(value = {
    @ApiResponse(code = 200, message = "OK"),
    @ApiResponse(code = 404, message = "Not Found"),
    @ApiResponse(code = 400, message = "Bad Request"),
    @ApiResponse(code = 500, message = "ISE")
})
public Response retrieveById(@ApiParam(value = "Some id") @PathParam("sid") int id) {
}

@ApiOperation(value = "Create object")
@ApiResponses(value = {
    @ApiResponse(code = 201, message = "Created"),
    @ApiResponse(code = 404, message = "Not Found"),
    @ApiResponse(code = 400, message = "Bad Request"),
    @ApiResponse(code = 500, message = "ISE")
})
public Response create(@ApiParam(value = "Request body") RequestBody body) {
}

如何避免使用Swagger annotations重演?

推荐答案

我在Google周围进行了一些搜索，并发现了 github问题和其他一些，似乎都没有一个可行的解决方案.

I did some Googling around and came across this github issue and some other SO questions that are not directly related to ApiResponses annotations and none of them seem to present a working solution.

使用Swagger UI 2.0我想让我们尝试一下，所以我做了以下

Using Swagger UI 2.0 I thought let's give it a try, so I did the following

1. 我创建了一个自定义注释GroupedApiResponses..
2. 我用一组Swagger注释对GroupedApiResponses..进行了注释
3. 我在端点顶部使用了GroupedApiResponses..批注
4. 像以前一样工作

1. I created a custom annotations GroupedApiResponses..
2. I annotated GroupedApiResponses.. with a group of Swagger annotations
3. I used the GroupedApiResponses.. annotations on top of endpoints
4. Works just like before

请参见下文

package com.raf.annotation;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

import io.swagger.annotations.ApiResponse;
import io.swagger.annotations.ApiResponses;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@ApiResponses(value = {
        @ApiResponse(code = 200, message = "Ok"),
        @ApiResponse(code = 404, message = "Not Found"),
        @ApiResponse(code = 400, message = "Bad Request"),
        @ApiResponse(code = 500, message = "ISE")
})
public @interface GroupedApiResponsesAvecOk {
}

类似地(根据端点的结构和它返回的响应消息，您可以根据需要将注释分组到一个或多个自定义注释中)

Similarly (you can group annotations as you want in one or more than one custom annotation depending on structure of your endpoints and the response messages it return)

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@ApiResponses(value = {
        @ApiResponse(code = 201, message = "Created"),
        @ApiResponse(code = 404, message = "Not Found"),
        @ApiResponse(code = 400, message = "Bad Request"),
        @ApiResponse(code = 500, message = "ISE")
})
public @interface GroupedApiResponsesAvecCreated {
}

然后我在retrieveById端点上的retrieveById和create端点上使用了上面的@GroupedApiResponsesAvecOk来代替@ApiResponses，并像以前一样工作.

And then I used the above @GroupedApiResponsesAvecOk on retrieveById and @GroupedApiResponsesAvecCreated on create endpoint in place of @ApiResponses and worked it just like before.

如上所示，与400, 404, 500有关的ApiResponse注释现在可以在其他端点之间重用.

As shown above, the ApiResponse annotations relating to 400, 404, 500 can now be reused across other endpoints.
