Java 使用Eclipse时多次注册AttributeConverter类

我有一个应用程序，使用STS和maven命令行可以很好地工作。 在代码中添加了新的AttributeConverter之后，它就不再工作了。我仍然能够使用maven命令行构建和运行它，但它不能在eclipse上运行。它不断提出同样的错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.AssertionFailure: AttributeConverter class [class com.mycompany.communication.model.EncryptionConverter] registered multiple times
