tomcat 启动和停止时发送邮件

1.使用maven下载jar

2.编写发送邮件代码：

package com.boce.server.tools;

import java.util.Properties;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;

/**

*/
public boolean SpringSendMailText(MailInfo mailInfo) {
if(!emailValidate(mailInfo)){
return false;
}
simpleMailMessage.setSubject(mailInfo.getSubject());
simpleMailMessage.setText(mailInfo.getText());

javaMailSender.send(simpleMailMessage);
logger.info("发送邮件成功");

return true;
}

/**

*/
public boolean SpringSendMailHtml(MailInfo mailInfo) {
// 建立邮件消息,发送简单邮件和html邮件的区别

logger.info(sb.toString(), e);

return false;
}

logger.info("发送邮件成功");

return true;
}

/**

*/
private boolean emailValidate(MailInfo mailInfo){
if (null == mailInfo) {

return false;

return true;

3.实现ServletContextListener 接口
package com.boce.server.listener;

import java.util.Enumeration;
import java.util.Properties;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.boce.server.tools.MailInfo;
import com.boce.server.tools.SendMailTools;
/**
* @author gjp
*
*/
public class ServerStopListener implements ServletContextListener{

static Logger log = LoggerFactory.getLogger(ServerStopListener.class);
@Override
public void contextDestroyed(ServletContextEvent event) {
log.info("====================================stop.............");
Enumeration<String> e = event.getServletContext().getAttributeNames();
while(e.hasMoreElements()){
System.out.println("name:"+e.nextElement());
}

MailInfo mailInfo = init();
mailInfo.setSubject("tomcat 关闭发送邮件");
mailInfo.setText("tomcat停止发送通知邮件邮件 ----stop.....");

sendMail(mailInfo);

}

@Override
public void contextInitialized(ServletContextEvent event) {
log.info("############################start#######################");

MailInfo mailInfo = init();
mailInfo.setSubject("tomcat 启动发送邮件");
mailInfo.setText("<html><header>test</header><body><a href='http://www.baidu.com'>baidu</a></body></html>");


sendMail(mailInfo);
}

//初始化邮件配置
private MailInfo init(){
MailInfo mailInfo = new MailInfo();
mailInfo.setHost("smtp.sina.com");
mailInfo.setMailfrom("[e-mail]");
mailInfo.setMailto("[e-mail]");
mailInfo.setUserName("gjp");
mailInfo.setPassword("g");

mailInfo.setSubject("tomcat 启动发送邮件");
mailInfo.setText("tomcat启动发送邮件 ----start......");

return mailInfo;
}


//发送邮件
public void sendMail(MailInfo mailInfo){
SendMailTools tools = new SendMailTools();
tools.sendEmailHtml(mailInfo);
}

}
