无法从 Eclipse 和 JDBC 连接到 SQL Server express 2012

Question

我尝试连接到安装在我自己机器上的 SQL Server express 2012。 在 Ms SQL name 的属性中是：BGHFVUI535V2\SQLEXPRESS

在 Java 中我有：

try
{
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

    databaseName = "dblfa1;integratedSecurity=true";
    String url = "jdbc:sqlserver://BGHFVUI535V2\SQLEXPRESS;user=mysa;password=mypsw;databaseName=dbmy";
    Connection con = DriverManager.getConnection(url);

}
catch (Exception e)
{
    e.printStackTrace();
}

我得到了这个例外：

com.microsoft.sqlserver.jdbc.SQLServerException: The connection to the host BGHFVUI535V2, named instance sqlexpress failed. Error: "java.net.SocketTimeoutException: Receive timed out". Verify the server and instance names and check that no firewall is blocking UDP traffic to port 1434.  For SQL Server 2005 or later, verify that the SQL Server Browser Service is running on the host.

    at ClassStart.main(ClassStart.java:34)

在 c# 中我有连接字符串：

string connectionString = "Server=BGHFVUI535V2\\SQLEXPRESS;Database=dbmy;User Id=mysa;Password=mypsw;"; 

它有效。

试试这个

String url = "jdbc:sqlserver://localhost;user=MyUserName;password=*****;";
