Question

我正在使用arquillian为Tomcat 8上部署的JAX-RS / Jersey Web服务创建集成测试。

我正在尝试执行类似的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

Answer 1

可能java.lang.IllegalStateException: Already connected仅屏蔽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。我遇到了这个问题，因为我的VPN丢失了连接。＆＃34; Already connected＆＃34;的例外情况在杰克逊序列化邮件正文期间报道。（我导入了Jersey和jackson-jaxrs-base的源代码进行调试）。删除邮件正文后，出现了错误的新异常＆＃34; Unknown hostname＆＃34 ;.

登录VPN后，一切正常。

我对泽西客户异常"Already connected＆＃34;非常不满意。这给了我什么，只有混乱。

问题可能在于SSL协商。尝试添加＆＃34; trustall＆＃34;客户初始化逻辑。

SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(null, new TrustManager[] { new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}

@Override
public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}

@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}

} }, new java.security.SecureRandom());

Client client = ClientBuilder.newBuilder().sslContext(sslcontext).hostnameVerifier((s1, s2) -> true)
.register(MultiPartFeature.class)
.register(new EncodingFeature("gzip", GZipEncoder.class))
.build();

调用connection.connect（）;

后，您可能在http连接上设置了header属性

尝试使用Jersey Client API执行POST请求的“已连接”异常
