我在这里有我的示例代码：
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%
/* Create string of connection url within specified format with machine name, port number and database name. Here machine name id localhost and database name is usermaster. */
String connectionURL = "jdbc:mysql://localhost/ekoh";
// declare a connection by using Connection interface
Connection connection = null;
// Load JBBC driver "com.mysql.jdbc.Driver"
Class.forName("com.mysql.jdbc.Driver").newInstance();
/* Create a connection by using getConnection() method that takes parameters of string type connection url, user name and password to connect to database. */
connection = DriverManager.getConnection(connectionURL, "root", "");
// check weather connection is established or not by isClosed() method
if(!connection.isClosed())
%>
<font size="+3" color="green"></b>
<%
out.println("Successfully connected to " + "MySQL server using TCP/IP...");
connection.close();
}
catch(Exception ex){
%>
</font>
<font size="+3" color="red"></b>
<%
out.println("Unable to connect to database.");
}
%>
我的数据库名称是“ekoh”，我使用了没有密码的 root 帐户。我仍然不知道为什么它到现在还不能工作。你能给我一些替代代码来运行吗？:) nb 我在 XAMPP 中使用 tomcat 和 MySql 编写 JSP。
