java - 有没有办法在Wildfly中禁用自动JSON PATCH应用程序

在Wildfly上的JAX-RS中使用HTTP-PATCH资源时（经过14和18测试），会发生一些自动魔术，使用GET调用相同的资源路径，应用JSON-PATCH中的更改并使用结果调用实际方法。

$ curl localhost:8080/so/auto/Bob -H 'Content-Type: application/json-patch+json' -X PATCH -d '[{"op":"replace","path":"/age","value":24}]' -v
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 8080 (#0)
> PATCH /so/auto/Bob HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.64.1
> Accept: */*
> Content-Type: application/json-patch+json
> Content-Length: 43
>
* upload completely sent off: 43 out of 43 bytes
< HTTP/1.1 200 OK
< Connection: keep-alive
< Transfer-Encoding: chunked
< Content-Type: application/json
< Date: Tue, 26 Nov 2019 12:45:51 GMT
<
* Connection #0 to host localhost left intact
{"age":24,"name":"Bob"}

有没有办法禁用此行为（使#patchManual工作）？

$ curl localhost:8080/so/manual/Bob -H 'Content-Type: application/json-patch+json' -X PATCH -d '[{"op":"replace","path":"/age","value":24}]' -v
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 8080 (#0)
> PATCH /so/manual/Bob HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.64.1
> Accept: */*
> Content-Type: application/json-patch+json
> Content-Length: 43
>
* upload completely sent off: 43 out of 43 bytes
< HTTP/1.1 400 Bad Request
< Connection: keep-alive
< Content-Type: text/plain;charset=UTF-8
< Content-Length: 41
< Date: Tue, 26 Nov 2019 12:42:58 GMT

* Connection #0 to host localhost left intact
not a json patch: {"name":"Bob","age":24}

                .add( "name", name )
                .add( "age", 42 )
                .build();
    }

最佳答案

当按下readManual()端点时，您正在此行JsonObject original = readManual( name );上调用patchManual()
