在我的开发过程中，我不得不使用 PATCH 方法调用一个 API，所以我编写了以下接口：
import javax.enterprise.context.Dependent;
import javax.ws.rs.Consumes;
import javax.ws.rs.PATCH;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;
@Dependent
@RegisterRestClient
@Produces(MediaType.APPLICATION_JSON)
public interface SimpleServiceMicroprofileApi {
@PATCH
@Path("api/sample/greet")
@Consumes(MediaType.APPLICATION_JSON)
public PojoEntity recallGreet(PojoEntity patch);
}
当我尝试调用recallGreet 方法时，会抛出一个javax.ws.rs.ProcessingException: java.net.ProtocolException: Invalid HTTP method: PATCH（下面的日志）。
经过一番调查，问题似乎是由HttpsURLConnection 实现引起的，并且存在一些不能解决我的问题的解决方法。我不得不使用 apache 客户端来调用这个 API……这个方法有什么技巧吗？
我创建了一个有这个问题的示例项目，只需部署它并调用http://localhost:8080/micro-sample/api/micro/recallGreet。
还在微配置文件存储库上打开了此行为的问题。
