我尝试通过jdbc将eclipse与sql server连接时，一直收到这两个错误信息。请问有人可以帮助我解决这个问题或者解释一下为什么会出现这种情况吗？
1. The TCP/IP connection to the host localhost, port 1433 has failed.
2. The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption.
谢谢。
String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
Class.forName(driver).newInstance();
String connString ="jdbc:sqlserver://localhost:1433/databaseName=Engg_Street;instance=SQLSERVER;encrypt=true; trustServerCertificate=true";
String username = "Vijayalakshmi";
String password = "";
conn = DriverManager.getConnection(connString,username,password);
