SpringBoot快速实现邮件发送功能-百测百灵

2018年11月10日星期六
随笔 笔记
springboot集成邮件发送
一、导入依赖包

 
    	org.springframework.boot
    	spring-boot-starter-mail
    

二、开启服务(一个即可)

三、发送短信:配置邮件客户端到1069…获取密码(每个人不一样)
四、配置文件application.yml 等同于application.properties
#发送邮件 层次yml规范

mail:
    password: pcchjrrbgifldegb  //发送短信到1069...获取的密码
    default-encoding: UTF-8
    host: smtp.qq.com    //smtp.163.com........
    properties:
      mail:
        smtp:
          starttls:
            enable: true
            required: true
          auth: true
    username:[email protected] //收件人地址邮件
  application:
    name: spirng-boot-mail
mail:
  fromMail:
addr:[email protected]  //发件人邮件地址(可不写)
#我的日志 
logging:
   level: 
     com:
       yyg: DEBUG

五、抽取后的代码

发送邮件附带文件/简单发送邮件
MailService
/**
 * 邮件服务接口
 * Date 2018/11/10
 * @Auther 阳彦刚
 */
public interface MailService {
    /**
     * 发送带附件的邮件和发送简单邮件 两个接口
     * @param to 接受者
     * @param subject 标题
     * @param content 发送内容
     * @param filePath 发送附件
     */
    void sendAttachmentsMail(String resiveUser,String subject,String content,String filePath);
    void  sendMail(String resiveUser,String subject,String content);
}

MailServiceImpl

 */
@Service //交给spring创建bean
public class MailServiceImpl implements MailService {
	/**

     */
	@Autowired
	EmailSendUtils emailSendUtils;
	@Override
	public void sendAttachmentsMail(String resiveUser, String subject, String content, String filePath) {
		emailSendUtils.sendAttachmentsMail(resiveUser, subject, content, filePath);
	}
	@Override
	public void sendMail(String resiveUser, String subject, String content) {
		emailSendUtils.sendMail(resiveUser, subject, content);
	}
}

工具类EmailUtils

/**

    package com.yyg.utils;
    import java.io.File;

    import org.springframework.scheduling.annotation.Async;
    import org.springframework.stereotype.Component;
    import org.springframework.stereotype.Service;
    @Component  //交给spring创建bean
    public class EmailSendUtils {
    	@Autowired
    	private JavaMailSender mailSender; //导入Mail.jar包自带的类,不用管
    	// 获取application.yml的值
    	@Value("${mail.fromMail.addr}")
    	private String form; //发件人邮箱地址
    	// 发送邮件 附带文件
    	@Async
    	public void sendAttachmentsMail(String resiveUser, String subject, String content, String filePath) {
    		//创建微型邮件对象
    		MimeMessage message = mailSender.createMimeMessage();
    		try {
    			MimeMessageHelper helper = new MimeMessageHelper(message, true);
    			helper.setFrom(form); //发件人邮件地址
    			helper.setTo(resiveUser); //收件人邮箱地址
    			helper.setSubject(subject); //邮箱标题
    			helper.setText(content);//邮件内容
    			//获取本地文件从文件输入流
    			FileSystemResource file = new FileSystemResource(new File(filePath));
    			String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
    			// 添加多个附件可以使用多条
    			helper.addAttachment(fileName, file);
    			mailSender.send(message);
    			System.out.println("带附件的邮件发送成功");
    		} catch (Exception e) {
    			e.printStackTrace();
    			System.out.println("发送带附件的邮件失败");
    		}
    	}

//简单发送邮件 接上

@Async //可用不管 用于集成Dubbo 消费优化的注解
	public void sendMail(String to, String subject, String content) {
		SimpleMailMessage mailMessage = new SimpleMailMessage();
		mailMessage.setFrom(form);// 发起者
		mailMessage.setTo(to);// 接受者

			System.out.println("发送简单邮件");
		} catch (Exception e) {
			System.out.println("发送简单邮件失败" + e.getMessage());

}

六、测试

package com.yyg.test;
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.SpringJUnit4ClassRunner;
import com.yyg.EmailRunApp;
import com.yyg.api.MailService;
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes=EmailRunApp.class)
public class testEmailSend {
	@Autowired
	MailService mailService;
//附带文件发送邮件测试
	@Test
	public void testSend()throws Exception{
		String filePath="D:\\谷歌下载\\a.jpg";
		mailService.sendAttachmentsMail("[email protected]", "附录邮件", "昔年残存终不负，化作巨龙腾飞",filePath);
	}
//简单发送邮件测试
	@Test
	public void testSend02()throws Exception{
		mailService.sendMail("[email protected]", "普通发送邮件", "昔年残存终不负，化作巨龙腾飞");
	}
}
