#Java邮件发件人-java.lang.NoClassDefFoundError： javax/激活/FileTypeMap

Question

我在Spring Configure Java类中创建Bean，如下所示:

@Bean
public JavaMailSender configureJavaMailSender() {
JavaMailSenderImpl sender = new JavaMailSenderImpl();
        sender.setHost("smtp.gmail.com");
        sender.setPort(587);
        sender.setUsername("[e-mail]");
        sender.setPassword("Goop@9790");

        Properties properties = new Properties();
        properties.put("mail.smtp.starttls.enable", true);
        properties.put("mail.smtp.ssl.trust", "smtp.gmail.com");
        
        sender.setJavaMailProperties(properties);
        return sender;
    }

我收到错误：

Java . lang . classnotfoundexception:javax . activation . file type map

Answer 1

JavaMailSenderImpl依赖于Javax Activation

<dependency>
    <groupId>com.sun.activation</groupId>
    <artifactId>javax.activation</artifactId>
    <version>1.2.0</version>
</dependency>
