我目前正在使用Spring Boot开发REST API。
我是Maven的新手,刚刚开始使用IDEA编写代码(还不熟悉这个IDE),我有一个问题......
这是我的项目结构:
因此,当我在Intellij中运行项目时,它会启动,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......看起来只有主模块被加载了。
这是我的父pom.xml:

我认为这是正确的,但不确定...... 我在带有配置的Maven的Intellij中运行项目:
mvn spring-boot:run -Drun.arguments=--spring.profiles.active=dev -e -pl main
需要你的帮助来配置运行Spring Boot的所有东西,并在IDE中加载所有子模块以用于开发目的......因为我不知道我的配置有什么问题!
Thx!
答案 0 :(得分:14)
您需要告诉SpringBoot在哪里寻找您的控制器。默认情况下,只发生在@SpringBootApplication
类的子包中(可能不包含子模块)。
为了更改它,您可以使用@ComponentScan("path.to.package")
更改默认包。
此外,您可以使用@EntityScan
对可能位于子模块中的@Entity
类执行相同的操作。
答案 1 :(得分:1)
您的项目结构如下:
如果您的App.java在一个包中: com.xxxx.pro ,那么设置子模块的包是 com.xxx.pro ,例如因为您的子模块的控制器是TestController.java,代码是:
package com.xx.pro.web;
@RestController
public class TestController{
}
所以,这个sub moudle的TestController将由App.java进行修复。试试吧,祝你好运。
答案 2 :(得分:0)
还要注意,如果JPA实体和存储库不在Application.java包的子包中,那么@Entityscan和@EnableJpaRepositories必须在Application类中声明,例如:
@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);
}
}
