无法在测试中修复“ EntityManagerFactory已关闭”

如何解决无法在测试中修复“ EntityManagerFactory已关闭”

我正在开发一个用Scala 2.11编写的项目，我们还使用Spring Boot 2.0和maven进行构建（这是一个多模块项目）。这也不是Web应用程序。

为了解决以下问题，我已经坚持了数周，这只有在使用maven对特定模块运行完整的测试集时才会发生：（mvn clean install -pl：workflow）

在运行单个测试甚至在隔离的程序包中进行多个测试时，都不会发生这种情况。

任何和所有与EntityManager相关的bean都由Spring处理。

我们已经为使用数据库客户端的所有测试添加了@Transactional批注；还添加了@DirtiesContext，没有任何更改。

我将非常感谢您提供有关调试/修复此问题的帮助或指示。
