SpringBoot学习－（二十三）SpringBoot发送邮件

基本步骤：

• 添加pom文件依赖
• 配置邮件相关
• 书写代码
• 测试

添加pom文件依赖

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

配置邮件相关

配置application.yml相关

spring:
  mail:
    host: smtp.aliyun.com
    username: xxxxxx@aliyun.com
    password: xxxxxx
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: false
            required: false

书写代码

实体类

package com.ahut.email;

import java.io.Serializable;
import java.util.HashMap;

public class Email implements Serializable
    /**
     * 序列化
     */
    private static final long serialVersionUID = 1L;
    // 必填参数
    private String email;// 接收方邮件
    private String subject;// 主题
    private String content;// 邮件内容
    // 选填
    private String template;// 模板
    private HashMap<String, String> kvMap;// 自定义参数

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getSubject() {
        return subject;
    }

    public void setSubject(String subject) {
        this.subject = subject;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getTemplate() {
        return template;
    }

    public void setTemplate(String template) {
        this.template = template;
    }

    public HashMap<String, String> getKvMap() {
        return kvMap;
    }

    public void setKvMap(HashMap<String, String> kvMap) {
        this.kvMap = kvMap;
    }

}

工具类

package com.ahut.email;

import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.atomic.AtomicInteger;

import javax.mail.internet.MimeMessage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

public class MailUtil
    private Logger logger = LoggerFactory.getLogger(MailUtil.class);

    private ScheduledExecutorService service = Executors.newScheduledThreadPool(6);

    private final AtomicInteger count = new AtomicInteger(1);

    public void start(final JavaMailSender mailSender, final SimpleMailMessage message) {
        service.execute(new Runnable() {
            @Override
            public void run() {
                try {
                    if (count.get() == 2) {
                        service.shutdown();
                        logger.info("the task is down");
                    }
                    logger.info("start send email and the index is " + count);
                    mailSender.send(message);
                    logger.info("send email success");
                } catch (Exception e) {
                    logger.error("send email fail", e);
                }

            }
        });
    }

    public void startHtml(final JavaMailSender mailSender, final MimeMessage message) {
        service.execute(new Runnable() {
            @Override
            public void run() {
                try {
                    if (count.get() == 2) {
                        service.shutdown();
                        logger.info("the task is down");
                    }
                    logger.info("start send email and the index is " + count);
                    mailSender.send(message);
                    logger.info("send email success");
                } catch (Exception e) {
                    logger.error("send email fail", e);
                }

            }
        });
    }

}

发送类

package com.ahut.email;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;

import com.ahut.action.LoginAction;

/**
 * 
 * @ClassName: MailService
 * @Description: 发送邮件
 * @author cheng
 * @date
@Service
public class MailService

    private Logger log = LoggerFactory.getLogger(LoginAction.class);

    @Autowired
    private JavaMailSender mailSender;// 执行者

    @Value("${spring.mail.username}")
    public String USER_NAME;// 发送者

    public void send(Email mail) throws Exception {
        log.info("发送邮件");
        MailUtil mailUtil = new MailUtil();
        SimpleMailMessage message = new

测试

package mail;

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;

import com.ahut.AhutApplication;
import com.ahut.email.Email;
import com.ahut.email.MailService;

@SpringBootTest(classes = AhutApplication.class)
@RunWith(SpringRunner.class)
public class MailTest {

    @Autowired
    private MailService mailService;

    @Test
    public void testSend() throws Exception {
        Email mail = new Email();
        mail.setEmail("xxxxx@163.com");
        mail.setSubject("注册验证");
        mail.setContent("多发一封应该没事");
        mailService.send(mail);
