1.导入Maven包。
[sourcecode language=”xml” title=”pom.xml”]
<!– 邮件发送 –>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
[/sourcecode]
2.配置属性文件。
[sourcecode language=”xml” title=”application.properties”]
#这个配置可以为空，后面我们可以自定义从数据库
#或者从文件拿到对应的参数实现动态的配置邮件
#邮件发送配置
spring.mail.host=
spring.mail.username=
spring.mail.password=
spring.mail.port= 465
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8
spring.mail.properties.smtp.auth=true
spring.mail.properties.smtp.starttls.enable=true
spring.mail.properties.smtp.starttls.required=true
spring.mail.properties.mail.smtp.ssl.enable=true
[/sourcecode]
3.编写邮件实体类。
[sourcecode language=”java” title=”Email.java”]
package com.liuliu.com.domain;

import lombok.Data;

//我这里用了lombok插件，所有不用写get/set方法
@Data
public class Email {
private Integer emailId;
private String emailHost;
private Integer emailPort;
private String emailUsername;
private String emailPassword;
private String emailCall;
private Integer emailPower;
}
[/sourcecode]
4.设置邮件发送的接口类。
[sourcecode language=”java” title=”EmailService.java”]
package com.liuliu.com.service;

import com.liuliu.com.domain.Email;

public interface EmailService {
public void emailText(Email email, String to, String subject, String text);
}
[/sourcecode]
5.实现邮件发送的方法。
[sourcecode language=”java” title=”EmailServiceImpl.java”]
package com.liuliu.com.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.liuliu.com.domain.Email;
import com.liuliu.com.service.EmailService;

@Service("EmailServiceImpl")
public class EmailServiceImpl implements EmailService{
@Autowired
private JavaMailSenderImpl mailSender;

public void emailText(Email email, String to, String subject, String text) {
// 发送邮件
//email发送属性的配置
//to收信人
//subject发送的标题
//text发送的内容
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
mailSender.setUsername(email.getEmailUsername());
mailSender.setHost(email.getEmailHost());
mailSender.setPassword(email.getEmailPassword());
mailSender.setPort(email.getEmailPort());
simpleMailMessage.setTo(to);
simpleMailMessage.setFrom(email.getEmailCall());
simpleMailMessage.setSubject(subject);
simpleMailMessage.setText(text);
mailSender.send(simpleMailMessage);
}
}
[/sourcecode]
