我们试图将数据库连接到用Java自定义的大厅/工作人员管理程序。这是一个多模块项目,我们的数据库团队决定使用SQL Server作为管理的基础。
不幸的是,这证明存在问题,导致大量错误,我们完全不确定如何修复。在搜索堆栈之后,出现了类似的问题,但要么没有解决,只是单独“开始工作”或者通过远离SQL Server而“修复”,我们也无法做到。
没有进一步的麻烦,这就是问题本身。该程序适当地对所有数据进行操作,因为它是在'testmode'中调试的,其中值直接馈送到代码中而不使用外部数据库。当试图把两个和两个放在一起时,出现了真正的问题。
首先,localhost的连接端口证明是有问题的。使用端口1433,我们甚至无法建立连接,甚至解锁端口也没有任何改变。移至1434后,我们设法建立了各种连接。
如果有必要,这是关于端口1433的错误块:
The TCP/IP connection to the host localhost, port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

将端口更改为1434后,我们遇到了另一个问题。出于某种原因,SQL Server使用Prelogin Handshake问题响应我们的连接,我们完全不知道如何修复。错误如下:

最后,我们遇到了一个排版问题,即文件和数据库中列的名称不匹配。不幸的是,纠正了更多错误。为了增加对伤害的侮辱,有时它甚至不会发现错配错误,所以我们在这里完全不知所措。
这是我们用于挂钩数据库的代码:
package database;
import java.sql.SQLException;
import POJO.Administrator;
import POJO.Equipment;
import POJO.Event;
import POJO.Guest;
import POJO.Personnel;
import POJO.Room;
import com.j256.ormlite.dao.Dao;
import com.j256.ormlite.dao.DaoManager;
import com.j256.ormlite.jdbc.JdbcConnectionSource;
import com.j256.ormlite.support.ConnectionSource;
public class DbManager {
// Proper db address should be placed here.
private final String DATABASE_URL = "jdbc:sqlserver://localhost:1434;databaseName=IO;integratedSecurity=true;";
private ConnectionSource connectionSource;
public Dao<Administrator,Integer> administratorDao;
public Dao<Equipment,Integer> equipmentDao;
public Dao<Event,Integer> eventDao;
public Dao<Guest,Integer> guestDao;
public Dao<Personnel,Integer> personnelDao;
public Dao<Room,Integer> roomDao;
public DbManager() throws SQLException
{
connectionSource = new JdbcConnectionSource(DATABASE_URL);
administratorDao = DaoManager.createDao(connectionSource, Administrator.class);
equipmentDao = DaoManager.createDao(connectionSource, Equipment.class);
eventDao = DaoManager.createDao(connectionSource, Event.class);
guestDao = DaoManager.createDao(connectionSource, Guest.class);
personnelDao = DaoManager.createDao(connectionSource, Personnel.class);
roomDao = DaoManager.createDao(connectionSource, Room.class);
}
@Override
protected void finalize() throws Throwable
{
connectionSource.close();
super.finalize();
}
}
我们完全没有想法,实际上,任何与将数据库从SQL Server完全重写为其他内容无关的任何内容都会有所帮助。提前谢谢!
答案 0 :(得分:4)
SQL Server Browser使用端口1434.验证SQL Server上是否启用了TCP / IP并再次尝试默认端口(1433)。
请参阅this post。
