Java 模块化Spring Boot 2应用程序导致集成测试失败

我有一个更大的Spring Boot应用程序（Nr.1），它由几个模块组成，大约20+（多模块设置）

在里面，我有另一个Spring Boot应用程序（Nr.2），它包含几个服务等

app-1
  +...
module-jpa
  +-- pom.xml
  +-- src/main/java/jpa/ (JPA Classes; Entities etc.)
module-repos
  +-- pom.xml
  +-- src/main/java/repos/ JPA Repositories; XYZ extends CrudRepository<..>.
module-app
  +-- pom.xml (dependency on module-jpa and module-repos)
  +-- src
       +-- main
             +-- java
                   +-- xyz
                        +-- application
                                +-- SpringBootApp.java
                   +-- services
                        +-- Service1.java
                        +-- Service2.java
  +-- src
       +-- test
             +-- java
                   +-- services
                        +-- Service1IT.java
                        +-- Service2IT.java
             +-- resources
                   +-- application.properties

但是现在

Service1IT.java

等的集成测试不再有效，出现以下异常：

xyzTest(xyz.abcIT)  Time elapsed: 0.141 s  <<< ERROR!
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'firstService': 
Unsatisfied dependency expressed through field 'secondService'; 
nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: 
Error creating bean with name '.........'repos.ABCRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

---

因此，在深入分析之后，我发现测试缺少

@EnableAutoConfiguration

注释，该注释解决了问题（其他注释除外），但这是最重要的注释
