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

Question

构建项目时出现以下错误。

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;

下面给出了从我的项目的 maven 依赖树中获取的 Spring 依赖。有人可以帮我确定哪个依赖项导致了这个问题。

Answer 1

您似乎缺少对 javax.mail 的依赖。

尝试将其添加到您的 Maven 依赖项中。

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