尝试使用Jersey Client API执行POST请求的"已连接"异常

Question

我正在使用arquillian为Tomcat 8上部署的JAX-RS/Jersey Webservice创建集成测试.

我正在尝试这样的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,我得到这个例外:

我可以使用一些启发式,因为我还在学习arquillian和Jersey客户端API :)谢谢

它可能java.lang.IllegalStateException: Already connected只是掩盖了SSLHandshakeException.请查看问题#3000(以前称为JERSEY-2728错误).

Answer 2

这可能是由于网络连接问题。由于VPN断开连接，我遇到了这个问题。Already connected在杰克逊序列化邮件正文期间报告了带有“ ”的异常。（我导入了Jersey和jackson-jaxrs-base的源代码进行调试）。删除邮件正文后，出现了新的异常，错误为“ Unknown hostname”。

登录我的VPN后，一切正常。

我对“泽西岛客户例外"Already connected” 感到非常不满，该例外只给我带来混乱。
