一、相关软件
这个不用说了吧
1. mysql
2. mysql-connector-java-5.1.22.jar
地址：http://dev.mysql.com/downloads/connector/j/
3. tomcat
二、连接要点
只需要将 mysql-connector-java-5.1.22.jar 放在 tomcat的lib目录下，即可。
如本人的：D:\ProgramFiles\WEB\apache-tomcat\lib\mysql-connector-java-5.1.22.jar
三、参考代码
<%@page contentType="text/html;charset=utf-8" %>
<%@page import="java.sql.*" %>
<html>
<body>
<%
Connection con;
Statement sql;
ResultSet rs;
try{
Class.forName("org.gjt.mm.mysql.Driver");//load database Driver
out.println("Driver loading success<br>");
}catch(ClassNotFoundException e){
out.println("Driver loading fail<br>");
}
String url="jdbc:mysql://localhost:3306/YourDatabase";
String userName = "YourUserName";
String passWord = "YourPassword";
try {
con = DriverManager.getConnection(url, userName, passWord);
if (con != null) {
out.println("Succeed connecting to the database<br>");
sql = con.createStatement();
rs = sql.executeQuery("select * from YourTable");
while(rs.next()){
out.println("Output Demo: "+rs.getString(2));
}
}
}catch(SQLException e){
out.println(e.getMessage());
}
%>
</body>
