JavaEE账号注册模拟网站邮箱激活

本项目是javaWeb和email结合的项目，模拟网站必须要激活邮箱账号才可以使用，

创建数据库

create table user(
id varchar(32) primary key,
name varchar(30),
pwd varchar(20),
email varchar(20),
active char(1),
acode varchar(32)
)

User.java值对象

package cn.hncu.reg.domain;

import javax.persistence.Table;

public class User {
  private String id;
  private String name;
  private String pwd;
  private String acode;
  private String active;
  private String email;

    return id;
  }
  public void setId(String id) {
    this.id = id;
  }
  public String getName() {
    return name;
  }
  public void setName(String name) {
    this.name = name;
  }
  public String getPwd() {

  }
  public void setPwd(String pwd) {
    this.pwd = pwd;
  }
  public String getAcode() {
    return acode;
  }
  public void setAcode(String acode) {
    this.acode = acode;
  }
  public String getActive() {
    return active;
  }
  public void setActive(String active) {
    this.active = active;
  }
  public String getEmail() {
    return email;
  }
  public void setEmail(String email) {
    this.email = email;
  }
  @Override
  public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + ((id == null) ? 0 : id.hashCode());
    return result;
  }
  @Override
