ssh+jmail实现，注册完发送邮件，点击链接之后完成注册。

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：

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 = "[e-mail]";     //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("[e-mail]", "password");       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。

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;}@Overridepublic 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：

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;@Overridepublic 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NOuser.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;}@Overridepublic 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：

<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）：

<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。
