没有 @PostConstruct 注释的 Spring Boot 初始化

Question

我开发了一个 Spring Boot 应用程序，目前可以很好地与 @PostConstruct 初始化。

现在，有了另一个要求，我在 Service 类中添加了另一个 initApp()，我发现该服务被初始化了两次 - 当使用 initApp() 从集成应用程序调用时以及默认情况下使用 postconstruct 注释方法时。

我只想用initApp() 进行初始化，所以我删除了postconstruct 带注释的方法。这样做，服务不会独立初始化（部署在 Web 服务器上），而是与集成应用程序一起正常工作。

有人可以帮助我如何在没有postconstrct 注释的情况下初始化服务，该注释在服务器上部署（作为战争文件）时有效？

这里是 pom.xml http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

我自己想出了一种方法来解决这个问题，方法是使用 @Postcontruct 注释在控制器类中初始化服务。
