我們試圖從本質上將數據庫連接到用Java構建的大廳/員工管理程序。這是一個多模塊項目，我們的數據庫團隊決定使用SQL Server作爲管理基礎。SQL Server數據庫連接錯誤
不幸的是，這證明有問題導致大量的錯誤，我們完全不知道如何解決。在搜索Stack之後，出現了類似的問題，但是這些問題或者沒有解決，並且通過從SQL Server中移出，而我們無法做到，只是自己開始工作或者「開始工作」。
毫不猶豫，這是問題本身。該程序正確運行所有數據，因爲它是在'testmode'中調試的，其中值不經外部數據庫直接輸入到代碼中。試圖將兩者結合在一起時出現了真正的問題。
首先，localhost的連接端口證明有問題。使用端口1433，我們甚至沒有建立連接，甚至解鎖端口也沒有任何改變。在移至1434後，我們設法建立了各種連接。
下面是關於1433端口錯誤塊，如果有必要：
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.".

在改變端口1434，我們用另一個問題打招呼。出於某種原因，SQL Server響應我們的連接，併發出Prelogin Handshake問題，我們完全不知道如何解決。這些錯誤如下：

最後，我們所遇到的地方在文件和數據庫中列名不匹配是一個排版問題。不幸的是，糾正這個問題導致了更多的錯誤出現。爲了增加對傷害的侮辱，有時它甚至沒有檢測到不匹配錯誤，所以我們在這裏完全處於損失狀態。
這裏是用來勾數據庫保持我們的代碼：
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
{

administratorDao = DaoManager.createDao(connectionSource, Administrator.class);
equipmentDao = DaoManager.createDao(connectionSource, Equipment.class);

}
@Override

{

}
我們是完全脫離的想法，真的，任何不關注或者完全從SQL Server數據庫改寫別的東西將是援助。先謝謝你！
請告訴我們您正在嘗試使用的實際Microsoft SQL Server版本（2012,2008,2005，...）和版本（Express Edition，Standard Edition，...）。 –
當然！我們使用帶有Service Pack 1的Microsoft SQL Server 2012開發人員。 – Dennet
要驗證SQL Server正在偵聽的端口，請參閱[此處]的說明（http://stackoverflow.com/a/12297597/2144390）。本文檔可能也有幫助：[如何配置SQL Server以偵聽特定端口]（http://support.microsoft.com/kb/823938）。 –
