Maven configuration with Spring Boot & multi modul

问题:

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

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

Here is my project structure :

  • parent
    • pom.xml
    • main module
      • controller
      • domain
      • App.java (Spring Boot main class)
      • pom.xml
    • sub module (need main module as dependency)
      • controllers
      • domain
      • pom.xml

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.

Here is my parent pom.xml :

<project>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.1.RELEASE</version>

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

  • working directory is root (not sub-module)
  • command line mvn spring-boot:run -Drun.arguments=--spring.profiles.active=dev -e -pl main
  • property start-class with parent.main.App

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 !

Thx !

回答1:

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).

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

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



回答2:

Your project structured as:

  • parent
    • pom.xml
    • main module
      • controller
      • domain
      • App.java (Spring Boot main class)
      • pom.xml (add sub moudle to main module as dependency)
    • sub module
      • controllers
      • domain
      • pom.xm

if your App.java in a package: com.xxxx.pro,then set the sub module's package is com.xxx.pro,such as your sub module's controller is TestController.java, and the code is:

package com.xx.pro.web;
@RestController
public class TestController{

}

so, this sub moudle's TestController will be sanned by App.java.Try it on, good luck.



回答3:

also note that in case of JPA Entities and repositories are not in sub packages of Application.java's package then @Entityscan and @EnableJpaRepositories MUST be declared in the Application class, e.g:

@Configuration
@ComponentScan(basePackages="com.my.pack")
@EnableAutoConfiguration
@EnableJpaRepositories(basePackages="com.my.pack")
@EntityScan(basePackages="com.my.pack")
public class Application{

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
