springboot傳送郵件的實現例子
阿新 • • 發佈：2018-12-03
springboot是集大成者，對於傳送郵件的功能也不例外。而且往往是原來的功能實現更簡單，方便。更符合Facade Pattern。
下面就是springboot傳送郵件的實現例子，程式碼已封裝好，按照提示的步驟配置好就可以直接用了。當然如果你是新搭的專案，需要引入springboot的mail包
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency> 引入後它會自動下載javax.mail包 上程式碼： package com.yy.common.utils; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.javamail.JavaMailSenderImpl; import org.springframework.mail.javamail.MimeMessageHelper; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import java.io.File; import java.util.Properties; /** * * @description: 傳送郵箱：可以傳送文字,可以附加html、圖片、附件，支援同時傳送多個郵箱 * 使用： * 第一步：在的專案的配置檔案(application.properties)中加入郵件配置 * spring.mail.host=smtp.163.com * spring.mail.username=***@163.com * spring.mail.password=*** * spring.mail.port=465 * spring.mail.default-encoding=UTF-8 * spring.mail.protocol=smtp * spring.mail.properties.mail.debug=true * spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory * spring.mail.properties.mail.smtp.auth=true * spring.mail.properties.mail.smtp.timeout=25000 * 第二步： * 在你呼叫此工具的類中，加入如下：此處利用springboot的feature * @Resource * private JavaMailSenderImpl mailSender;
