SpringBoot定時發送郵件


前提: 

1.Springboot項目

2.引入maven 依賴

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>

以下代碼中涉及到的maven依賴有日志依賴,但是springboot都有集成,不用重新引入依賴

Application(程序入口)

package com.springbootemaildemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
/**
 * 引入了一個注解@EnableSwagger2來啟動swagger注解。(啟動該注解使得用在controller中的swagger注解生效, 覆蓋的范圍由@ComponentScan的配置來指定,
 * 這里默認指定為根路徑”com.springboot”下的所有controller)
 * 也可以單獨寫衣swaggerConfigura
 */
@EnableScheduling //啟動定時任務
@EnableSwagger2  //啟動swagger注解
@SpringBootApplication
public class MailApplication {
    public static void main(String[] args) {
        SpringApplication.run(MailApplication.class, args);
    }
}

 MailJob(定時任務類)

package com.springbootemaildemo.job;

import com.springbootemaildemo.send.SendMail; import com.springbootemaildemo.send.TenSenvenMail; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; import javax.annotation.Resource; @Component @EnableScheduling public class MailJob { private static final Logger logger = LoggerFactory.getLogger(MailJob.class); @Resource SendMail sendMail; @Resource TenSenvenMail tenSenvenMail; //@Scheduled(cron = "0/5 * * * * ?") //或直接指定時間間隔,例如:100秒 // @Scheduled(fixedRate=100000) //早晨7點 @Scheduled(cron = "0 0 7 * * ?") public void sendJob() { String bodyTen = "早安哇,太陽出來啦,記得開心喲"; String bodyWen = "記得開心喲"; logger.info("定時任務開始.........................."); sendMail.sendWen(bodyWen); tenSenvenMail.sendTen(bodyTen); logger.info("定時任務結束.........................."); } }

@EnableScheduling 這個注解是 開啟定時任務。

發送郵件代碼:

發送普通的郵件(發送郵件類):

package com.springbootemaildemo.send;

import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Component; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import java.util.Date; import java.util.Properties; @Component public class SendMail { private static final Logger logger = LoggerFactory.getLogger(SendMail.class); public void sendWen(String body) { logger.info("開始發送.................."); String from = "212212@qq.com"; String to = "5456456@qq.com"; String subject = "HAPPY"; String smtpHost = "smtp.qq.com"; Properties props = new Properties(); props.setProperty("mail.transport.protocol", "smtp"); // 使用的協議(JavaMail規范要求) props.setProperty("mail.smtp.host", smtpHost); // 發件人的郵箱的 SMTP服務器地址 props.setProperty("mail.smtp.auth", "true"); // 請求認證,參數名稱與具體實現有關 // 創建Session實例對象 Session session = Session.getDefaultInstance(props); // 創建MimeMessage實例對象 MimeMessage message = new MimeMessage(session); // 設置發件人 try { message.setFrom(new InternetAddress(from)); // 設置收件人  message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to)); // 設置發送日期 message.setSentDate(new Date()); // 設置郵件主題  message.setSubject(subject); // 設置純文本內容的郵件正文  message.setText(body); // 保存並生成最終的郵件內容  message.saveChanges(); // 設置為debug模式, 可以查看詳細的發送 log session.setDebug(true); // 獲取Transport對象 Transport transport = session.getTransport("smtp"); // 第2個參數需要填寫的是QQ郵箱的SMTP的授權碼,什么是授權碼,它又是如何設置? transport.connect(from, "ipeiquufachheefg"); // 發送,message.getAllRecipients() 獲取到的是在創建郵件對象時添加的所有收件人, 抄送人, 密送人  transport.sendMessage(message, message.getAllRecipients()); logger.info("發送完成"); transport.close(); } catch (MessagingException e) { e.printStackTrace(); } } }
