structs1.x的配置及一个简单的登陆例子

登陆和增删改查的全部代码例子：http://download.youkuaiyun.com/detail/asdfzjs/6269881

 

1，首先通过用myeclipse，new一个web project，如下图：

2，点击finsh,然后右键点击我的项目project,选择Myeclipse，再选择add struts，如下图：

3，可以直接点击finish。这样配置就可以算结束了。

4，下面是包的搭建(仅供参考);

5,util包里面的操作数据库的：

package com.sims.util;


import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
/**
*
* @title HelperClass
* @description 系统帮助类

*
*/
public class HelperClass {
/**
*
* @title getConn
* @description 连接驱动
* @author zjs
* @create_date May 9, 2013
* @return
*/
public static final Connection getConnection() {
Connection conn = null;
try {
Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/sims??useUnicode=true&characterEncoding=utf-8&autoReconnect=true", "root", "123456");
} catch (ClassNotFoundException e) {
System.out.println("异常信息为:"+e.getMessage()+"OK");
e.printStackTrace();
} catch (SQLException e) {
System.out.println("异常信息为:"+e.getMessage()+"OK");
e.printStackTrace();
}
return conn;
}
/**
*
* @title close
* @description 关闭链接
* @author tanqi
* @create_date May 9, 2013
* @param conn 连接对象
* @param s 事务处理
* @param rs 结果集
*/
public static final void close(Connection connection, Statement statement, ResultSet resultSet) {
try {
if (connection!= null) {
connection.close();
}
if (statement!= null) {
statement.close();
}
if (resultSet!= null) {
resultSet.close();
}
} catch (SQLException e) {
System.out.println("异常信息为:"+e.getMessage()+"OK");
e.printStackTrace();
}
}
}

6，action包里的UserForm

package com.sims.userManager.action.from;

7,service层
