最近做的一个项目中有个邮件发送功能,发送邮件默认是25端口,但是公司用的服务器是阿里云的,会屏蔽25端口,所以部署到服务器后连接不上邮件服务器,需要使用SSL协议(使用465端口)。
需要注意的是Spring Boot 的版本问题,低版本只支持使用默认的25端口进行发送,或者使用SSL协议时的配置有所区别,我的Spring Boot 的版本信息最开始是1.3.0.RELEASE,在开发完成后测试的时候发现使用465端口死活连不上邮件服务器,只能通过25端口发送,对比了以前我做的项目,发现只有boot的版本不一样,于是我修改了一下版本信息,修改后如下所示:
- <parent>
-
<groupId>org.springframework.boot</groupId>
-
<artifactId>spring-boot-starter-parent</artifactId>
-
<version>1.4.7.RELEASE</version>
-
</parent>
代码实现细节如下
一、添加maven依赖
-
<dependency>
-
<groupId>org.springframework.boot</groupId>
-
<artifactId>spring-boot-starter-mail</artifactId>
-
</dependency>
二、添加配置信息
-
#邮件配置
-
spring.mail.host=邮件服务器地址
-
spring.mail.username=用户名
-
spring.mail.password=密码
-
spring.mail.default-encoding=UTF-8
-
#登录服务器是否需要认证
-
spring.mail.properties.mail.smtp.auth=true
-
#SSL证书Socket工厂
-
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
-
#使用SMTPS协议465端口
-
spring.mail.properties.mail.smtp.socketFactory.port=465
-
-
#显示在收件人邮箱里面的发件人名称
-
spring.mail.self.username=用户名
三、Java代码
-
import java.io.File;
-
import java.util.List;
-
-
import javax.mail.MessagingException;
-
import javax.mail.internet.InternetAddress;
-
import javax.mail.internet.MimeMessage;
