JSP项目中的JDBC SQL Server连接错误

问题描述 投票:1回答:1

我正在尝试连接到SQL Server。

从代码连接到服务器时,它给我一个错误:

javax.servlet.ServletException: java.sql.SQLException: Network error IOException: Connection refused: connect

下面给出代码:

<%@page import="java.sql.DriverManager"%>
<%@page import="java.sql.ResultSet"%>
<%@page import="java.sql.Statement"%>
<%@page import="java.sql.Connection"%>
<%@page import="java.sql.SQLException"%>


<%
    Class.forName("net.sourceforge.jtds.jdbc.Driver");
    Connection cn = DriverManager
            .getConnection("jdbc:jtds:sqlserver://MSI;DatabaseName=LeadManagement;user=sa;password=123456");

    Statement stmt = cn.createStatement();
    ResultSet rs = stmt.executeQuery("select * from userDetail");
%>

屏幕快照-SQL Server连接实例

为什么会出现此错误?

java sql-server jsp jdbc

尝试使用此更新的代码段:

<%@page import="java.sql.DriverManager"%>
<%@page import="java.sql.ResultSet"%>
<%@page import="java.sql.Statement"%>
<%@page import="java.sql.Connection"%>
<%@page import="java.sql.SQLException"%>


<%
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    String url = "jdbc:sqlserver://MSI;databaseName=LeadManagement;user=sa;password=123456;";
    Connection connection = DriverManager.getConnection(url);   
    Statement stmt = connection.createStatement();
    ResultSet rs = stmt.executeQuery("select * from userDetail");
%>

注意:从here下载Microsoft JDBC驱动程序jar。

要注意的另一点-请验证网址。它必须遵循以下语法-jdbc:sqlserver://<server>:<port>
