java - 尝试使用 Jersey Client API 执行 POST 请求时出现“已连接”异常

Question

我正在使用 arquillian 为部署在 Tomcat 8 上的 JAX-RS/Jersey Web 服务创建集成测试。

我正在尝试执行这样的 POST 请求:

E dummy = dummyFactory.manufacturePojo(getSubClassType());
dummy.setId(null);

Client client = ClientBuilder.newClient();
WebTarget target = client.target(BASE_URI).path("bandeira");

Response response = target.request(MediaType.APPLICATION_JSON)
            .header(HttpHeaders.AUTHORIZATION, CHAVE_TESTE)
            .header(HttpHeaders.CONTENT_TYPE, "application/json")
            .post(Entity.entity(dummy, MediaType.APPLICATION_JSON));

当我这样做时，我得到了这个异常:

我可以使用一些启发式方法，因为我仍在学习 arquillian 和 Jersey 客户端 API :) 谢谢

可能是 java.lang.IllegalStateException: Already connected 只屏蔽了 SSLHandshakeException。请看issue #3000 (以前称为 JERSEY-2728 错误)。
