使用Eclipse

我有一个应用程序，以前使用STS和maven命令行工作正常。 在代码更改后，添加了新的AttributeConverter，它不再起作用了。我仍然可以使用maven命令行构建和运行它，但它不会在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

新的AtrributeConverter（EncryptionConverter）仅在一个类中使用。有人知道这里有什么问题吗？ 为什么它使用命令行（mvn spring-boot：run），但不使用eclipse？

1 个答案:

答案 0 :(得分：0)

我遇到了同样的问题，在我的情况下，这是由于我对包含Converter的同一个模块进行了两次引用。

转到“项目结构”（⌘;）/模块/依赖关系，并确保没有两个完全相同的依赖关系。就我而言，我有：

  • 对包含转换器的模块的直接IntelliJ引用
  • 和另一个到同一模块的Jar。
