Maven 配置与 Spring Boot &多模块 - 在 Intellij 中运行应用程序 [英] Maven configuration with Spring Boot & multi modules - run application in Intellij

问题描述

我目前正在使用 Spring Boot 开发 REST API.

I'm currently working on a REST API with Spring Boot.

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

I'm new to Maven and have just started coding with IDEA (don't know well this IDE yet), and I have a problem...

这是我的项目结构:

• 父母
  • pom.xml
  • 主模块
    • 控制器
    • 域
    • App.java(Spring Boot 主类)
    • pom.xml
    • 控制器
    • 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控制器中定义的所有 URL.但不是子模块控制器中的那些......看起来只加载了主模块.

    So when I run the project in Intellij, it starts, and I can access all URLs defined in the main module controller. But not the ones in the sub module controller... It looks like only the main module was loaded.

    这是我的父 pom.xml :

    Here is my parent pom.xml :

    我认为这是正确的，但不确定...我在 Intellij 中使用 Maven 和 config 运行项目:

    I think that's correct, but not sure... I run the project in Intellij with Maven with config :

    • 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
    • property start-class with parent.main.App

    需要您的帮助来配置所有这些东西以运行 Spring Boot，并将所有子模块加载到 IDE 中以用于开发目的...因为我不知道我的配置有什么问题！

    Need your help to configure all that stuff to run Spring Boot with all sub-modules loaded in the IDE for dev purpose... because I readlly don't know what is wrong in my config !

    谢谢！

    推荐答案

    你需要告诉 SpringBoot 去哪里寻找你的控制器.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).

    You need to tell SpringBoot where to look for your controllers. Per default that only happens in sub-packages of your @SpringBootApplication class (which will probably not include your sub module).

    为了改变你可以使用 @ComponentScan("path.to.package") 来改变默认包.

    In order to change that you can use @ComponentScan("path.to.package") to change the default package.

    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.

    Additionally, you can use @EntityScan to do the same for @Entity classes that might be in your sub-module.
