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：

<span style="color: #333333;">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); } } </span><span style="color: #ff6666;"> </span>
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; } @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：

<span style="color: #333333;">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!"); } } } </span>
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。
