如何为JAX-RS提供@PATCH注释？ [英] How to have a @PATCH annotation for JAX-RS?

问题描述

JAX-RS有HTTP动词的注释，例如 GET （ @GET ）和 POST （ @POST ）但没有 @PATCH 注释。如何为 PATCH HTTP动词添加注释？

JAX-RS has annotations for HTTP verbs such as GET (@GET) and POST (@POST) but there is no @PATCH annotation. How can I have an annotation for the PATCH HTTP verb?

如下所示：

@PATCH
public Response someCode() {
    // Code to handle the request
}

推荐答案

我得到答案在其他地方。

一个只需要定义一个自定义补丁注释，这意味着您必须使用以下代码编写 PATCH.java 文件：

One will just have to define a custom Patch annotation, what that means is that you will have to write a PATCH.java file with following code:

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@HttpMethod("PATCH")
public @interface PATCH {
}

导入包含PATCH的包。 java ，然后就像其他HTTP方法注释一样使用它：

Import the package containing PATCH.java and then you can use it like other HTTP method annotations:

@PATCH
@Path("/data/{keyspace}")
@Produces({ "application/json" })
public void patchRow(@PathParam("keyspace") String keyspace, String body) 
throws Exception

我用这个@PATCH将一些JSON发送到我的REST服务。

I used this @PATCH to send some JSON to my REST service.
