Question

我在构建项目时遇到以下错误。

City\controller\MyMailHelper.java:59: cannot access javax.mail.internet.MimeMessage
class file for javax.mail.internet.MimeMessage not found

在应用程序代码中，我指的是以下导入。

import org.springframework.mail.javamail.MimeMailMessage;
import org.springframework.mail.javamail.MimeMessageHelper;

从我项目的maven依赖树中获取的Spring依赖关系如下。有人可以帮我确定哪个依赖关系正在解决这个问题。

您似乎缺少对javax.mail的依赖。

尝试将此添加到Maven依赖项中。

<dependency>
   <groupId>javax.mail</groupId>
   <artifactId>mail</artifactId>
   <version>1.4.7</version>
</dependency>

从repo下载工件似乎存在一些问题。昨天。今天当我运行mvn clean install时，它下载了一些昨天没有发生的文件。今天看到没有错误让我感到震惊。今天从repo下载了这些工件。这些罐子带来了javax.mail：mail：jar：1.4.1

当我使用SpringBoot的启动程序邮件时遇到了这个异常，该启动程序邮件为Spring的JavaMailSender接口提供了自动配置和启动程序模块。我未能在正确的gradle子项目中提供依赖项。

要修复该异常，请确保提供了“ libraries.springBootStarterMail”依赖项。

找不到javax.mail.internet.MimeMessage的类文件
