java - Spring Boot war 在 Elastic Beanstalk 中启动时失败，但在本地运行时正确启动

Question

在本地运行没有问题的同一 war 文件失败，并出现以下循环错误:

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webSecurityConfig': Unsatisfied dependency expressed through field 'customSuccessHandler': Error creating bean with name 'customSuccessHandler': Unsatisfied dependency expressed through field 'engineerService': Error creating bean with name 'engineerServiceImpl': Unsatisfied dependency expressed through field 'engineerRepository': Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'engineerServiceImpl': Unsatisfied dependency expressed through field 'engineerRepository': Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customSuccessHandler': Unsatisfied dependency expressed through field 'engineerService': Error creating bean with name 'engineerServiceImpl': Unsatisfied dependency expressed through field 'engineerRepository': Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'engineerServiceImpl': Unsatisfied dependency expressed through field 'engineerRepository': Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'engineerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class mvc.domain.Engineer

看起来像我们的 CustomSuccessHandler -> Autowiring @Service -> 它又连接由 JPA 实体组成的存储库。它似乎不喜欢 JPA 实体。我遇到的问题是，在本地运行时，相同的 war 文件将加载而不会出现错误。

过去我已经能够在 pom 中切换依赖项版本，它将解决该问题。这非常不稳定，我似乎找不到可重复的模式

我能够使用以下方法一致地重现这一点:

$ eb 部署

但是，如果我转到 GUI Web 控制台并从应用程序版本重新部署相同的 war，我就可以毫无问题地加载相同的 war 文件。

我猜测这是通过 python eb cli 工具部署 war 时 Elastic Beanstalk 代理出现的某种错误。

Elastic Beanstalk 版本:

运行 Tomcat 8 Java 8 的 64 位 Amazon Linux 2017.03 v2.6.1

eb cli 版本:

EB CLI 3.10.1 (Python 3.6.0)

当我部署时，我将通过网络 GUI 继续摇动 handle ，并认为这个问题已经解决。但是，如果其他人遇到过这个问题并且有更好的解决方法，我很想听听。
