我目前正在使用 Spring Boot 开发 REST API。

我是 Maven 新手，刚开始使用 IDEA 进行编码(还不太了解这个 IDE)，但我遇到了一个问题...

这是我的项目结构:

• parent
  • pom.xml
  • 主模块
    • Controller
    • 域
    • App.java(Spring Boot 主类)
    • pom.xml
  • 子模块(需要主模块作为依赖)
    • Controller
    • 域
    • pom.xml

所以当我在 Intellij 中运行项目时，它会启动，并且我可以访问主模块 Controller 中定义的所有 URL。但不是子模块 Controller 中的那些......看起来只加载了主模块。

这是我的父 pom.xml :

我认为这是正确的，但不确定... 我在 Intellij 中使用带有配置的 Maven 运行项目:

• 工作目录是根目录(不是子模块)
• 命令行mvn spring-boot:run -Drun.arguments=--spring.profiles.active=dev -e -pl main
• 带有 parent.main.App 的属性开始类

需要您的帮助来配置所有这些东西以运行 Spring Boot 并在 IDE 中加载所有子模块以用于开发目的......因为我真的不知道我的配置有什么问题!

谢谢!

最佳答案

你需要告诉 SpringBoot 在哪里寻找你的 Controller 。默认情况下，这只发生在您的 @SpringBootApplication 类的子包中(可能不包括您的子模块)。

为了改变这一点，你可以使用 @ComponentScan("path.to.package") 来改变默认包。

此外，您可以使用 @EntityScan 对可能在您的子模块中的 @Entity 类执行相同的操作。
