SpringBoot 傳送郵件

1、引入依賴
<!--郵件-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
2、配置地址
spring: mail: # 配置 SMTP 伺服器地址 host: mail.xxxx.com # 傳送者郵箱 username: [email protected] # 配置密碼，注意不是真正的密碼，而是剛剛申請到的授權碼 password: xxxxxxx # 埠號465或587 port:25 # 預設的郵件編碼為UTF-8 default-encoding: UTF-8 # 配置SSL 加密工廠 properties: mail: smtp: socketFactoryClass: javax.net.ssl.SSLSocketFactory #表示開啟 DEBUG 模式，這樣，郵件傳送過程的日誌會在控制檯打印出來，方便排查錯誤 debug: true
3、編寫郵件類
package com.hiscene.has.sys.mail.service.impl; import com.hiscene.has.sys.mail.service.MailService; import com.hiscene.util.ThreadPoolUtil; import freemarker.template.Configuration; import freemarker.template.Template; import lombok.SneakyThrows; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.ResourceLoader; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service; import javax.mail.internet.MimeMessage; import java.util.HashMap; import java.util.concurrent.ThreadPoolExecutor; @Service @Slf4j public class MailServiceImpl implements MailService { @Autowired private JavaMailSender javaMailSender; @Autowired ResourceLoader resourceLoader; @Value("${spring.mail.username}") private String sender; @SneakyThrows @Override public Boolean sendSimpleMail(String receiver, String subject, String username, String pwd) { try { //建立message MimeMessage message = javaMailSender.createMimeMessage(); MimeMessageHelper helper= new MimeMessageHelper(message, true); // //發件人 helper.setFrom( "發郵件中文名稱"+" <"+sender+">"); //收件人 helper.setTo(receiver); //標題 helper.setSubject(subject); HashMap map = new HashMap(); map.put("username", username); //解析模板並替換動態資料，最終username將替換模板檔案中的${username}標籤。 String contents = "<html><body>"+username+"<br>"+ pwd + "</body></html>"; helper.setText(contents, true); //傳送郵件 javaMailSender.send(message); return true; } catch (Exception e) { return false; } } }
