1.制作一个邮件发送类（SendMail.java）代码如下：
package cn.ssh.struts.util;
import org.springframework.mail.MailException;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
public class SendMail {
private MailSender mailSender;
private SimpleMailMessage mailMessage;
public SendMail() {
}
public SimpleMailMessage getMailMessage() {
return mailMessage;
}
public void setMailMessage(SimpleMailMessage mailMessage) {
this.mailMessage = mailMessage;
}
public MailSender getMailSender() {
return mailSender;
}
public void setMailSender(MailSender mailSender) {
this.mailSender = mailSender;
}
public void sendMail() {
SimpleMailMessage message = new SimpleMailMessage(mailMessage);
//设置email内容,
message.setText("Hello 我是杨占辉.这是一个用Spring发送的测试邮件.");
try {
mailSender.send(message);
} catch (MailException e) {
// TODO Auto-generated catch block
System.out.println("O . 发送Email失败了.");
e.printStackTrace();
}
}
}
2.在applicationContext.xml中进行相应的如下配置：
<!-- ******************************** 以下为邮件自动发送示例的配置 ********************************** -->
<!-- mailSender -->
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host">
<value>smtp.163.com</value>
</property>
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop><!-- 如果要使用用户名和密码验证,这一步需要 -->
<prop key="mail.smtp.timeout">25000</prop>
</props>
</property>
<property name="username">
<value>yangzhanhui</value>
</property>
<property name="password">
<value>yangzhanhui</value>
</property>
</bean>
<!-- 简单的message -->
<bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage">
<property name="to">
<value>yangzhanhui@neusoft.com</value>
</property>
<property name="from">
<value>yangzhanhui@163.com</value>
</property>
<property name="subject"> <!-- Email 标题 -->
<value>你好，朋友．</value>
</property>
</bean>
<!-- sendMail -->
<bean id="sendMail" class="cn.ssh.struts.util.SendMail">
<property name="mailMessage">
<ref bean="mailMessage"/>
</property>
<property name="mailSender">
<ref bean="mailSender"/>
</property>
</bean>
3.在Action中调用邮件自动发送业务，代码如下：
public class UserAction extends Action {
/*
* Generated Methods
*/
private User user;
private UserService userService;
private SendMail sendMail;
/**
* @return the sendMail
*/
public SendMail getSendMail() {
return sendMail;
}
/**
* @param sendMail the sendMail to set
*/
public void setSendMail(SendMail sendMail) {
this.sendMail = sendMail;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
/**
* Method execute
*
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
UserForm userForm = (UserForm) form;
user.setUsername(userForm.getUsername());
user.setPassword(userForm.getPassword());
if (userService.login(user)) {
sendMail.sendMail();
return mapping.findForward("success");
} else {
return mapping.findForward("fail");
}
}
}
补充说明：
我在进行完以上所有工作以后，直接启动Tomcat进行测试，但是出现了下面的错误信息：
ERROR ContextLoader:211 - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Error registering bean with name 'javaMailSender' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Class that bean class [org.springframework.mail.javamail.JavaMailSenderImpl] depends on not found; nested exception is java.lang.NoClassDefFoundError: javax/mail/MessagingException
java.lang.NoClassDefFoundError: javax/mail/MessagingException
经过调查，解决方法如下：
把j2ee中的activation.jar,和mail.jar包复制到Tomcat中的common/lib目录下,重新发布就成功了.
以下转载于其它网络资源：
搞了很久都不明白是什么回事,因为在测试时都没有问题,而且提示中的包在项目里都有.最后通过网上搜索把问题解决了，原来在使用Spring这样的框架的一些丰富功能时，都要在完整的J2EE容器下运行，因为Spring只不过提供J2EE容器功能的又一种调用方式罢了，所以把j2ee中的activation.jar,和mail.jar包复制到Tomcat中的common/lib目录下就发布成功了．
