我正在将 Java jdk/jre6 与 Eclipse 一起使用，并且正在努力解决将我的应用程序客户端 SSLSocket 连接到 SSL 服务器的问题。
我非常感谢任何帮助处理这个问题，因为我被困住了。
我使用密钥工具创建了一个自签名 jks 并设置了系统属性并创建了一个 SSL 套接字
System.setProperty("javax.net.ssl.keyStore", "C:/.../mystore.jks");
System.setProperty("javax.net.ssl.keyStorePassword","thepassword");
System.setProperty("javax.net.ssl.trustStore", "C:/.../mystore.jks");
System.setProperty("javax.net.ssl.trustStorePassword","thepassword");
SSLSocket sslsocket= (SSLSocket) SSLSocketFactory.getDefault().createSocket(ip,port);
但是，当我尝试我的第一个套接字写入时，我抛出了一个异常。
socket.getOutputStream().write(message.getBytes(),0,message.length());
