另外，在我实现邮件生成逻辑的java文件中，为该java文件生成了两个类文件。 Javafile name:EmailUtil.java 类文件生成EmailUtil.Class和EmailUtil$1.Class

请任何人帮助解决此问题

删除：

<dependency>
        <groupId>javax.mail</groupId>
        <artifactId>javax.mail-api</artifactId>
        <version>1.5.1</version>

    </dependency>

javax.mail
javax.mail-api
1.5.1
com.sun.mail
javax.mail
1.5.3
javax.mail
邮件
1.4.5

并保持：

   <dependency>
                <groupId>javax.mail</groupId>
                <artifactId>mail</artifactId>
                <version>1.4.5</version>
        </dependency>

javax.mail

尝试了此操作，但问题仍然存在
