SpringBooot + Spring mail 發送郵件demo

• 一、建立springboot項目 導入mail與boot整合依賴
• 二、配置檔案application.properties
• 三、代碼實作
• 四、定時發送郵件

一、建立springboot項目 導入mail與boot整合依賴

pom檔案引入

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

二、配置檔案application.properties

server.port=8081
spring.mail.host=smtp.163.com
spring.mail.port=
#發件方賬戶
[email protected]
#密碼
spring.mail.password=password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
           

三、代碼實作

1、目錄

2、MailService

/**
 * @Author sgh
 * Description: 
 */
public interface MailService {
    boolean send(String to, String title, String content);
    boolean sendToSome(String[] to, String title, String content);
}

           

3、MailServiceImpl

import com.sgh.demofortest.mail.service.MailService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.mail.MailProperties;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;


/**
 * @Author SUGUANHAN
 * Description:
 */
@Service
@Slf4j
public class MailConServiceImpl implements MailService {

    private MailProperties mailProperties;
    private JavaMailSender javaMailSender;

    @Autowired
    public MailConServiceImpl(MailProperties mailProperties, JavaMailSender javaMailSender) {
        this.mailProperties = mailProperties;
        this.javaMailSender = javaMailSender;
    }

    /**
      * @Description :  單發郵件
      * @author sgh
      * @param to        郵件接受者郵箱
      * @param title     郵件标題
      * @param content   郵件内容
      * @return boolean
      */
    @Override
    public boolean send(String to, String title, String content) {
        log.info("send mail.. to {},title {},content {}",to,title,content);
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        //郵件發送者
        simpleMailMessage.setFrom(mailProperties.getUsername());
        //郵件接受者
        simpleMailMessage.setTo(to);
        //郵件标題
        simpleMailMessage.setSubject(title);
        //郵件内容
        simpleMailMessage.setText(content);
        try {
            log.info("begin to send mail...");
            javaMailSender.send(simpleMailMessage);
        } catch (MailException e) {
            log.info("sorry! there is something wrong...  {}",e.getMessage());
            return false;
        }
        return true;
    }

    /**
      * @Description :  群發郵件
      * @author sgh
      * @param to
      * @param title
      * @param content
      * @return boolean
      */
    @Override
    public boolean sendToSome(String[] to, String title, String content) {
        for (String receiver : to) {
            try {
                this.send(receiver,title,content);
            } catch (Exception e) {
                log.error("something wrong! {}",e.getMessage());
                return false;
            }
        }
        return true;
    }
}
           

4、測試

import com.sgh.demofortest.mail.service.MailService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemofortestApplicationTests {

    @Autowired
    private MailService mailService;


    @Test
    public void contextLoads() {
        String to = "[email protected]";
        String title = "a mail for java test";
        String content = "外面的人聽着  被包圍了我們";
        mailService.send(to,title,content);
    }

    @Test
    public void sendToSomeTest(){
        String [] receivers = {"[email protected]","[email protected]"};
        mailService.sendToSome(receivers,"測試","測試一下而已");
    }

}

           

四、定時發送郵件

休息一下
