java JDBC关于登录数据库
public static void main(String[] args) {
    Connection conn=null;
           try {                               

conn=DriverManager.getConnection("jdbc:sqlserver://localhost:1433;DatabaseName=master","sa","sa");
System.out.println("建立连接成功");
} catch (SQLException e) {
e.printStackTrace();
}

数据库登录名,密码没错,并且可以登录
localhost也没错!
但是java控制台的错误是:
com.microsoft.sqlserver.jdbc.SQLServerException: 用户 'sa' 登录失败。
