最近实现一个邮件推送功能，整理如下:
1 编写线程类实现runnable接口:（其中JavaMailUtil为封装的发送邮件工具类）
import lombok.Data;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
/**
* @author an-ping
* @date 2019/3/31
*/
@Data
public class MailThread implements Runnable {
String to;
String subject;
String name;
String company;
String photo;
int jid;
public MailThread( String to, String subject, String name, String company, String photo, int jid) {
this.to = to;
this.subject = subject;
this.name = name;
this.company = company;
this.photo = photo;
this.jid = jid;
}
JavaMailUtil javaMailUtil=(JavaMailUtil) ApplicationContextProvider.getBean("javaMailUtil");
@Override
public void run() {
javaMailUtil.sendTemplateMail(to,subject,name,company,photo,jid);
}
}2 JavaMailUtil为发送邮件工具类:
import org.apache.catalina.webresources.FileResource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;
import org.thymeleaf.IEngineConfiguration;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;
import org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver;
import org.thymeleaf.templatemode.TemplateMode;
import org.thymeleaf.templateresolver.ITemplateResolver;
import org.thymeleaf.templateresolver.ServletContextTemplateResolver;
import org.thymeleaf.templateresolver.TemplateResolution;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
import java.util.Map;
/**

@Component
public class JavaMailUtil {
@Autowired
JavaMailSender MailSender;
public JavaMailSender getMailSender() {
return MailSender;
}
public void setMailSender(JavaMailSender mailSender) {
MailSender = mailSender;
}
public TemplateEngine getTemplateEngine() {
return templateEngine;
}
public void setTemplateEngine(TemplateEngine templateEngine) {
this.templateEngine = templateEngine;
}
@Value("${mail.fromMail.addr}")
private String from="[email protected]";
//发送简单消息
public int sendSimpleMail(String to,String text,String subject){
SimpleMailMessage simpleMailMessage=new SimpleMailMessage();
simpleMailMessage.setFrom(from);
simpleMailMessage.setTo(to);
simpleMailMessage.setSubject(subject);
simpleMailMessage.setText(text);
try {
System.out.println(simpleMailMessage);
System.out.println(MailSender);
MailSender.send(simpleMailMessage);
return 1;//发送成功
} catch (MailException e) {
e.printStackTrace();
return 0;//发送失败
}
}
//发送html格式文本
public int sendHtmlMail(String to,String subject,String text){
MimeMessage mimeMessage=MailSender.createMimeMessage();
try {
MimeMessageHelper mimeMessageHelper=new MimeMessageHelper(mimeMessage,true);
mimeMessageHelper.setFrom(from);
mimeMessageHelper.setTo(to);
mimeMessageHelper.setSubject(subject);
mimeMessageHelper.setText(text,true);//html格式为true
MailSender.send(mimeMessage);
return 1;
} catch (MessagingException e) {
e.printStackTrace();
return 0;
}
}
public int sendAttachMail(String to,String text,String subject,String path){
MimeMessage mimeMessage=MailSender.createMimeMessage();
try {
MimeMessageHelper mimeMessageHelper=new MimeMessageHelper(mimeMessage,true,"utf-8");
mimeMessageHelper.setFrom(from);
mimeMessageHelper.setText(text,true);
mimeMessageHelper.setSubject(subject);
mimeMessageHelper.setTo(to);
FileSystemResource fileSystemResource=new FileSystemResource(new File(path));
String fileName=path.substring(path.lastIndexOf(File.separator));
mimeMessageHelper.addAttachment(fileName,fileSystemResource);
MailSender.send(mimeMessage);
return 1;
} catch (MessagingException e) {
e.printStackTrace();
return 0;
}
}
public int sendPicMail(String to,String text,String subject,String path,String id){
MimeMessage mimeMessage=MailSender.createMimeMessage();
try {
MimeMessageHelper mimeMessageHelper=new MimeMessageHelper(mimeMessage,true);
mimeMessageHelper.setTo(to);
mimeMessageHelper.setFrom(from);
mimeMessageHelper.setText(text,true);
mimeMessageHelper.setSubject(subject);
FileSystemResource fileSystemResource=new FileSystemResource(new File(path));
mimeMessageHelper.addInline(id,fileSystemResource);
MailSender.send(mimeMessage);
return 1;
} catch (MessagingException e) {
e.printStackTrace();
return 0;
}
}
@Autowired
TemplateEngine templateEngine;
public int sendTemplateMail(String to,String subject,String name,String company,String photo,int jid){
//创建邮件正文
Context context = new Context();
context.setVariable("name", name);
context.setVariable("company", company);
context.setVariable("url", "http://www.tap2019.top:2019/front/jobpage.action?"+jid);
context.setVariable("photo","http://www.tap2019.top:2019/"+photo);
System.out.println(templateEngine+"模板引擎");
String emailContent = templateEngine.process("j", context);
int result=sendHtmlMail(to,subject,emailContent);
return result;
}
}
3 控制层:
@RequestMapping(value="/tuiJobs.action",method = RequestMethod.POST)
@ResponseBody
public JsonMode tuiSend(String company,String photo,int jid){
JsonMode jsonMode=new JsonMode();
TempPage<People> list= peopleService.findEmailAndName(new People());
List peoplelist=list.getRows();
People people=null;
ExecutorService executorService=new ThreadPoolExecutor(2,4,30, TimeUnit.SECONDS,new LinkedBlockingDeque<>(),new ThreadPoolExecutor.CallerRunsPolicy());
try {
for(int i=0;i<peoplelist.size();i++){
people=(People)peoplelist.get(i);
executorService.execute(new MailThread(people.getEmail(),"jobguru-职位推荐",people.getName(),company,photo,jid));
jsonMode.setCode(Common.Request_success);
}
} catch (Exception e) {
jsonMode.setCode(Common.Request_fail);
e.printStackTrace();
}
return jsonMode;
}
}
