在尝试使用jdbc连接到sql server时，我遇到了以下连接异常。
有人能帮忙解决这个问题吗？
我正在使用sqljdbc4.jar文件连接到sql server
代码如下

String dbURL = "jdbc:sqlserver://10.156.54.123;encrypt=false;DatabaseName=PRA;sslProtocol=TLSv1;";
 String user = "username";
 String pass = "password";
 conn = DriverManager.getConnection(dbURL, user, pass);

这是个例外。
