我在日志中看到以下异常(-Djavax.net.debug = all)：
main,handling exception: java.net.socketException: Connection reset main,SEND TLSv1.2 ALERT: fatal,description = unexpected_message main,WRITE: TLSv1.2 Alert,length = 2 main,Exception sending alert: java.net.socketException: Connection reset by peer: socket write error
经过depeer分析后,我观察到问题是由于使用Java 8而不是发送服务器名称(SNI),而是使用Java 7发送该问题,并且Web服务调用成功工作.
Java 8 log(-Djavax.net.debug = all)：缺少“Extension server_name”

观察到使用Java 7,扩展名server_name,server_name：[host_name：testeo.hostname.es]被设置,然后Web服务调用成功工作.
Java 7为什么没有将server_name设置为Java 7？是Java配置问题吗？
解决方法
https://bugs.openjdk.java.net/browse/JDK-8144566
我们的解决方法：
测试后,我们发现将连接的SSLSocketFactory设置为与默认值相似的任何内容似乎可以解决问题.
这不行：
HttpsURLConnection.setSSLSocketFactory((SSLSocketFactory)SSLSocketFactory.getDefault());
这样做有效：
HttpsURLConnection.setSSLSocketFactory(new SSLSocketFactoryFacade());
所以,要修复一个JAX-WS客户端,你可以这样做：
bindProvider.getRequestContext().put(“com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory”,新的SSLSocketFactoryFacade());
我们的SSLSocketFactory门面:(注意它真的没有做任何事情)
public class SSLSocketFactoryFacade extends SSLSocketFactory {
SSLSocketFactory sslsf;
public SSLSocketFactoryFacade() {
sslsf = (SSLSocketFactory) SSLSocketFactory.getDefault();;
}
@Override
public String[] getDefaultCipherSuites() {
return sslsf.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return sslsf.getSupportedCipherSuites();
}
@Override
public Socket createSocket(Socket socket,String s,int i,boolean b) throws IOException {
return sslsf.createSocket(socket,s,i,b);
}
@Override
public Socket createSocket(String s,int i) throws IOException,UnkNownHostException {
return sslsf.createSocket(s,i);
}
@Override
public Socket createSocket(String s,InetAddress inetAddress,int i1) throws IOException,inetAddress,i1);
}
@Override
public Socket createSocket(InetAddress inetAddress,int i) throws IOException {
