到主机本地主机，端口1433的TCP / IP连接失败

问题描述

当我尝试通过 jdbc 连接eclipse与 sql server 时，我重复得到这2个错误。有没有人可以帮我这个或解释为什么我得到这个？

  1。到主机本地主机，端口1433的TCP / IP连接失败。 
 2.驱动程序无法使用安全套接字层（SSL）加密建立与SQL Server的安全连接。 
  

谢谢。

  String driver =com.microsoft.sqlserver.jdbc.SQLServerDriver; 
 Class.forName（driver）.newInstance（）; 
 String connString =jdbc：sqlserver：// localhost：1433 / databaseName = Engg_Street; instance = SQLSERVER; encrypt = true; trustServerCertificate = true; 
 String username =Vijayalakshmi; 
 String password =; 
 conn = DriverManager.getConnection（connString，username，password）; 
  

解决方案

 开始> Microsoft SQL Server>配置工具> SQL Server配置管理器
  

打开时转到

  SQL Server配置管理器> SQL Server网络配置> SQLExpress的协议
  

在哪里可以找到协议TCP / IP，如果禁用，启用它点击TCP / IP，您将找到其属性。

在此属性中删除所有TCP动态端口并将1433的值添加到所有TCP端口
并重新启动SQL Server服务> SQL Server

其完成...

I'm getting this 2 errors repeatedly when I'm trying to connect eclipse with sql server through jdbc. Could anyone help me with this or explain why am I getting this?

1. The TCP/IP connection to the host localhost, port 1433 has failed.
2. The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption.

Thank you.

String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
Class.forName(driver).newInstance();
String connString      ="jdbc:sqlserver://localhost:1433/databaseName=Engg_Street;instance=SQLSERVER;encrypt=true;     trustServerCertificate=true";
String username = "Vijayalakshmi";
String password = "";
conn = DriverManager.getConnection(connString,username,password);

解决方案

You need to Go to Start > Microsoft SQL Server > Configuration Tools > SQL Server Configuration Manager

When it opens Go to

SQL Server Configuration Manager > SQL Server Network Configuration > Protocols for SQLExpress

Where you'll find the Protocol TCP/IP, if disabled then Enable it Click on TCP/IP, You'll find its properties.

In this properties Remove All the TCP Dynamic Ports and Add value of 1433 to all TCP Portand restart your SQL Server Services > SQL Server

And Its Done...
