Struts+Ajax
首先看下页面strutsAjax.jsp
再看下Myjsp.jsp
下面是Action
连接数据库的类
操作数据库的类
最后是StrutsConfig

再看下Myjsp.jsp

下面是Action

}
}
连接数据库的类
package com.StrutsAjaxTest.DBConnect;
import java.sql.Connection;
import java.sql.DriverManager;
public class DBConnect {
private static Connection con = null;
private DBConnect(){}
public static DBConnect getDBConnect(){
return new DBConnect();
}
public Connection getConnection(){
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection("jdbc:odbc:MQIS","sa","sa");
}catch(Exception e){
e.printStackTrace();
System.out.println("创建数据库连接出错!");
}
return con;
}
/*public static void main(String args[]){
System.out.println(DBConnect.getConnection());
}*/
}
操作数据库的类
package com.StrutsAjaxTest.DBConnect.Query;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Vector;
import com.StrutsAjaxTest.DBConnect.DBConnect;

}
