本文实例为大家分享了SpringBoot JavaMailSender发送邮件的具体代码，供大家参考，具体内容如下
引入Maven依赖包
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
163邮箱
application.properties
#####163邮箱######## spring.mail.host=smtp.163.com spring.mail.username=*****@163.com #163邮箱密码 spring.mail.password=!@#$%^&* spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.starttls.enable=true spring.mail.properties.mail.smtp.starttls.required=true
运行类：
import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.test.context.junit4.SpringRunner; @RunWith(SpringRunner.class) @SpringBootTest(classes=Application.class) public class My163MailTest { @Autowired private JavaMailSender javaMailSender; @Value("${spring.mail.username}") private String username; @Test public void testSendSimple() { SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(username); message.setTo("*******@qq.com"); message.setSubject("标题：测试标题"); message.setText("测试内容部份"); javaMailSender.send(message); } } QQ邮箱和163邮箱的区别是需要设置授权码而不是密码，具体操作参考： 地址
application.properties
######qq邮箱######## spring.mail.host=smtp.qq.com spring.mail.username=******@qq.com #QQ邮箱授权码 spring.mail.password=xuojxtkdojvzbhjj spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.starttls.enable=true spring.mail.properties.mail.smtp.starttls.required=true
运行类：
import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.test.context.junit4.SpringRunner; @RunWith(SpringRunner.class) @SpringBootTest(classes=Application.class) public class MyQQMailTest { @Autowired private JavaMailSender javaMailSender; @Value("${spring.mail.username}") private String username; @Test public void testSendSimple() { SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(username); message.setTo("******@qq.com"); message.setSubject("标题：测试标题"); message.setText("测试内容部份"); javaMailSender.send(message); } } 以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持亿速云。
