我在使用＆＃34; javax.ws.rs.client.Client（Jersey client 2.25.1）＆＃34;时遇到了问题。在多线程上下文中发送https请求。
1）首先，我创建一个如下客户端：
Client client = ClientBuilder.newBuilder().sslContext(createSSLContext()).build();
private static SSLContext createSSLContext() throws Exception {
SSLContext sslcontext = SSLContext.getInstance(TLS);
KeyManagerFactory kmf =
KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
try (InputStream keyStoreSteam = new FileInputStream(keystoreFile)) {
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(keyStoreSteam, keystorePwd.toCharArray());
kmf.init(ks, keystorePwd.toCharArray());
}
try (InputStream trustStoreSteam = new FileInputStream(trustStoreFile)) {
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(trustStoreSteam, trustStorePwd.toCharArray());
tmf.init(trustStore);
sslcontext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), new java.security.SecureRandom());
}
return sslcontext;
}
2）我正在使用＆＃34;客户端＆＃34;发送https请求如下：
for(int i = 0; i < 3; i++){
public void run(){
while(true){
Builder request = client.target(url).request(theString);
Request request = request.get();
// other stuffs ...
Thread.current.sleep(5000);
}
}
}).start();
3）在request.get()中抛出异常。请注意，request.get()有3个调用线程，但只有一个线程成功获得响应，其他2个线程获得如下异常：

似乎3个线程在通过https发送请求时尝试加载认证，但只有1个线程成功，其他2个线程找不到有效的认证路径。 但是一个请求成功发送后，在休眠后的下一个循环中，所有3个线程都可以成功发送请求。因此，异常仅发生在多线程上下文中的第一个发送请求中。
这是泽西岛客户端的一个错误，还是我错误地使用了它？
答案 0 :(得分：0)
这似乎是泽西岛的一个错误 - 特别是所有最新版本（直到26-b09）。 请参阅 - https://github.com/jersey/jersey/issues/3293
降级到版本2.21.1为我解决了这个问题..
