最近在做一个项目，需要发送邮件到注册邮箱，并且点击链接之后方可完成注册。直接上代码：
发送邮件的类：
[java] view plaincopy
package com.guang.utils;

import java.io.PrintWriter;
import java.util.Properties;

import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.servlet.http.HttpServlet;

public class SendEmail {

 public void send(String to){




 String subject="东京网上商城邮箱验证提醒";
 String content="感谢您于"+timeutil.getnowdate()+"在东京商城注册，复制以下链接，即可完成安全验证："
 +"http://10.5.116.117/e_shop/registbyEmail.action?checkemail="+to

 +"为保障您的帐号安全，请在24小时内点击该链接，您也可以将链接复制到浏览器地址栏访问。"+
"若您没有申请过验证邮箱，请您忽略此邮件，由此给您带来的不便请谅解。";


 String host = "smtp.163.com"; //发件人使用发邮件的电子信箱服务器

 String from = "kobe_guang@163.com"; //发邮件的出发地（发件人的信箱）

 Properties props = System.getProperties();
 // 设置邮件服务器
 props.put("mail.smtp.host", host);
 // 取得session
 props.put("mail.smtp.auth", "true"); //这样才能通过验证
 MyAuthenticator myauth = new MyAuthenticator("kobe_guang@163.com", "4515079");
 Session session = Session.getDefaultInstance(props, myauth);
 // session.setDebug(true);
 // 定义message
 MimeMessage message = new MimeMessage(session);
 try{

 // 设定发送邮件的地址
 message.setFrom(new InternetAddress(from));
 // 设定接受邮件的地址
 message.addRecipient(Message.RecipientType.TO,
 new InternetAddress(to));
 // 设定邮件主题
 message.setSubject(subject);
 // 设定邮件内容
 BodyPart mdp=new MimeBodyPart();//新建一个存放信件内容的BodyPart对象
 mdp.setContent(content,"text/html;charset=gbk");//给BodyPart对象设置内容和格式/编码方式
 Multipart mm=new MimeMultipart();//新建一个MimeMultipart对象用来存放BodyPart对
 //象(事实上可以存放多个)
 mm.addBodyPart(mdp);//将BodyPart加入到MimeMultipart对象中(可以加入多个BodyPart)
 message.setContent(mm);//把mm作为消息对象的内容
 // message.setText(content);
 message.saveChanges();
 Transport.send(message);
 }catch(Exception e){

 e.printStackTrace();
 }

 }


}

class MyAuthenticator extends javax.mail.Authenticator {
 private String strUser;
 private String strPwd;
 public MyAuthenticator(String user, String password) {
 this.strUser = user;
 this.strPwd = password;
 }

 protected PasswordAuthentication getPasswordAuthentication() {
 return new PasswordAuthentication(strUser, strPwd);
 }
}



第一个action：用于在点击链接之后修改用户的状态。
[java] view plaincopy
package com.guang.action;

import com.guang.model.User;
import com.guang.service.UserService;
import com.guang.utils.UserStatus;
import com.opensymphony.xwork2.ActionSupport;

public class FinishregisterAction extends ActionSupport {

 /**
 *
 */
 private static final long serialVersionUID = 1L;
 private String checkemail;


 public String getCheckemail() {
 return checkemail;
 }

 public void setCheckemail(String checkemail) {
 this.checkemail = checkemail;
 }

 UserService userService;

 public UserService getUserService() {
 return userService;
 }


 public void setUserService(UserService userService) {
 this.userService = userService;
 }


 @Override
 public String execute() throws Exception {

 System.out.println("checkemail="+checkemail);

 User user=userService.getUniqueResult(checkemail);

 user.setStatus(UserStatus.YES);

 this.userService.modify(user);


 return SUCCESS;

 }

}

注册的action：

[java] view plaincopy
package com.guang.action;

import java.io.PrintWriter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.components.FieldError;

import com.guang.model.ShoppingCart;
import com.guang.model.User;
import com.guang.service.UserService;
import com.guang.service.impl.UserServiceImpl;
import com.guang.utils.UserStatus;
import com.guang.utils.timeutil;
import com.opensymphony.xwork2.ActionSupport;

public class RegisterAction extends ActionSupport {

 private String repassword;

 private User user;

 UserService userService;

 @Override
 public String execute() throws Exception {

 //注册时间
 user.setRegisterdate(timeutil.getnowdate());

 //初始时，没有邮箱验证，所以设为NO
 user.setStatus(UserStatus.NO);


 ShoppingCart scart=new ShoppingCart();

 scart.setCartitemid(3);
 scart.setUser(user);
 user.setShoopingcart(scart);
 userService.addShoppingCart(scart);
 userService.addUser(user);

 return SUCCESS;
 }

 public String getRepassword() {
 return repassword;
 }


 public User getUser() {
 return user;
 }

 public UserService getUserService() {
 return userService;
 }

 public void setRepassword(String repassword) {
 this.repassword = repassword;
 }



 public void setUser(User user) {
 this.user = user;
 }

 public void setUserService(UserService userService) {
 this.userService = userService;
 }

 @Override
 public void validate() {

 if(this.user.getPassword().equals(this.repassword)){

 }else{

 addFieldError("reg_error", "两次密码输入不一致，请重新输入!");
 }
 }




}


对应方法调用不列出了。
struts.xml里面的配置：
[html] view plaincopy
<action name="register" class="RegisterAction">
 <result name="success" type="redirect">/qiantai/go_check.jsp</result>
 <result name="input">/qiantai/register.jsp</result>
 </action>

 <action name="listAllUsers" class="ListAllUsers">
 <result name="success">/list.jsp</result>
 </action>

 <action name="imageCode" class="com.guang.action.ImageCodeAction">
 <result name="success" type="stream">
 <param name="inputName">imageStream</param>
 <param name="bufferSize">2048</param>
 </result>
 </action>

 <action name="checkcode" class="com.guang.action.ImageCodeAction" method="checkCode">
 <result></result>
 </action>


 <action name="checkemail" class="checkemail" >
 <result></result>
 </action>

 <action name="login" class="login_">
 <result name="success">/qiantai/goodslist.jsp</result>
 <result name="input">/qiantai/login.jsp</result>
 </action>

 <action name="go_register" class="com.guang.action.MiddleAction">
 <result name="success">/qiantai/register.jsp</result>
 </action>

 <action name="go_login" class="com.guang.action.MiddleAction" method="login">
 <result name="login">/qiantai/login.jsp</result>
 </action>


 <action name="registbyEmail" class="finishregister">
 <result name="success" type="redirect" >/qiantai/registerbyEmail.jsp</result>
 </action>



spring的配置文件（部分）：
[html] view plaincopy
<bean id="userservice" class="com.guang.service.impl.UserServiceImpl">
 <property name="userdao" ref="userdao"></property>
 <property name="sendemails" ref="sendmail"></property>
</bean>

<bean id="RegisterAction" class="com.guang.action.RegisterAction" scope="prototype">
 <property name="userService" ref="userservice"></property>
</bean>

<bean id="ListAllUsers" class="com.guang.action.UserAction" scope="prototype">
 <property name="userService" ref="userservice"></property>
</bean>

<bean id="checkemail" class="com.guang.action.checkEmailAction" scope="prototype">
 <property name="userService" ref="userservice"></property>
</bean>

<bean id="login_" class="com.guang.action.LoginAction" scope="prototype">
 <property name="userService" ref="userservice"></property>
</bean>

<bean id="finishregister" class="com.guang.action.FinishregisterAction" scope="prototype">
 <property name="userService" ref="userservice"></property>
</bean>

基本完成了。
希望对你有帮助。
