1.新建一个Dynamic Web Project项目，里面加入要用到的jar包，整体的框架如图所示：

2.新建一个数据库，里面新建一张表，表结构如图所示：

3.用易邮邮件服务器新建几个账号，整体框架如图所示：

4.用foxmail新建几个邮箱，整体框架如下所示：

5.UserDao.java代码：

package dao;

import java.sql.SQLException;

import domain.User;

public interface UserDao {

	void regist(User user) throws SQLException;

	User findByCode(String code) throws SQLException;

	void update(User user) throws SQLException;

}

6.UserDaoImpl.java代码：

package dao;

import java.sql.SQLException;

import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanHandler;

import utils.JdbcUtils;
import domain.User;

public class UserDaoImpl implements UserDao {

	@Override
	public void regist(User user) throws SQLException {
		QueryRunner queryRunner = new QueryRunner(JdbcUtils.getDataSource());
		String sql = "insert into user values (?,?,?,?,?,?,?)";
		Object[] params = { user.getUid(), user.getUsername(),
				user.getPassword(), user.getNickname(), user.getEmail(),
				user.getState(), user.getCode() };
		queryRunner.update(sql, params);
	}

	@Override
	public User findByCode(String code) throws SQLException {
		QueryRunner queryRunner = new QueryRunner(JdbcUtils.getDataSource());
		String sql = "select * from user where code = ?";
		User user = queryRunner.query(sql, new BeanHandler<User>(User.class),
				code);
		return user;
	}

	@Override
	public void update(User user) throws SQLException {
		QueryRunner queryRunner = new QueryRunner(JdbcUtils.getDataSource());
		String sql = "update user set username=?,password=?,nickname=?,email=?,state=?,code=? where uid=?";
		Object[] param = { user.getUsername(), user.getPassword(),
				user.getNickname(), user.getEmail(), user.getState(),
				user.getCode(), user.getUid() };
		queryRunner.update(sql, param);
	}

}

	private Integer uid;
	private String username;
	private String password;
	private String nickname;

	public Integer getUid() {
		return uid;
	}

	public void setUid(Integer uid) {
		this.uid = uid;
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

		this.password = password;
	}

	public String getNickname() {
		return nickname;
	}

	public void setNickname(String nickname) {
		this.nickname = nickname;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

19.在浏览器里面输入http://localhost:8080/regist/regist.jsp运行，输入user01和user02的信息，其中user01只是注册，不按照提示去邮件激活，而user02则根据提示去邮件激活，然后看看数据库里面的code和state的状态，比较一下两者的不同：
