搞了一天了，还是没有解决
由于需要用到SQLServer，数据库登录方式是Sqlserver和Windows混合登录，在Microsoft SQL Server Management Studio中可以用sa账户登录，但是在Java代码中登录不了，这是为什么？求大牛指点：
[code="java"]import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBtest {
public static void main(String[] args){
String URL="jdbc:sqlserver://192.168.88.201:1433;databaseName=master";
String USERNAME="sa";
String PASSWORD="123";
String DRIVER="com.microsoft.sqlserver.jdbc.SQLServerDriver";
Connection conn = null;
try {
Class.forName(DRIVER);
conn = DriverManager.getConnection(URL,USERNAME,PASSWORD);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
System.out.println(conn);
}
}
[/code]
代码没有问题，也能用Microsoft SQL Server Management Studio中可以用sa账户登录，就是用Java连不上/抛异常是：
