开发环境:Maven + IDE + SpringBoot + 微软邮箱
引入SpringBoot的邮件依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
在 application.properties 配置文件中添加邮件的相关配置
#SMTP 服务器地址 如何是其他邮箱 请自行搜索
spring.mail.host=smtp.live.com
#邮箱地址
spring.mail.username=yahocen@hotmail.com
#邮箱密码 如何开启了授权码 就填写授权码
spring.mail.password=xxxxx
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

测试类 SendMailTest.java
import java.io.File;
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 SendMailTest {
@Autowired
private SendMail sendMail;
@Test
public void sendSimpleMail() {
sendMail.sendSimpleMail("543754816@qq.com", "这是纯文本邮件标题", "纯文字内容");
}
@Test
public void sendHtmlMail() {
String html = "<a href='http://yahocen.xyz'>这是一个连接</a>";
sendMail.sendHtmlMail("543754816@qq.com", "这是html邮件标题", html);
}
@Test
public void sendAttachmentsMail() {
String html = "<a href='http://yahocen.xyz'>这是一个连接</a>";
sendMail.sendAttachmentsMail("543754816@qq.com", "这是html邮件标题", html, true, "附件名称", new File("C:\\Users\\yahoc\\Desktop\\照片.jpg"));
}
}
在SendMail.java中为什么还需要引入from属性,难道配置文件中已经包含了吗?我测试过,如果去掉setFrom会导致错误。我猜想可以在配置文件中配置多个邮箱参数,然后指定from属性进行发送。大家可以自行测试,以上提到的单邮箱已经满足了大多数功能需求。
