Question

我正在使用以下方式检查与eclipse和sql的连接，我正在使用带有Windows身份验证的默认数据库

import java.sql.*;
public class TestConnection {

    static final String dbUrl = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=master";
//master is the name of default database of sql server
    public static void main(String[] args) {

        try {
            Connection conn = DriverManager.getConnection(dbUrl);
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            System.out.println(e.getMessage());
        }
        // TODO Auto-generated method stub

        System.out.println("Done.");

    }

}

我使用的是sql server 2008 R2 我收到错误“连接链接失败”

错误

com.microsoft.sqlserver.jdbc.SQLServerException：与主机MYPC的连接，命名实例sqlexpress失败。错误：“java.net.UnknownHostException：MYPC”。验证服务器和实例名称，并检查没有防火墙阻止到端口1434的UDP流量。对于SQL Server 2005或更高版本，请验证SQL Server Browser服务是否正在host.Done上运行
