Spring Boot多模块包扫描问题

1.@SpringBootApplication

@SpringBootApplication(scanBasePackages = "cn.mypackage1","cn.mypackage1")
public class Application {

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

}

使用@SpringBootApplication的scanBasePackages属性，配置scanBasePackages扫描多个包及子包内的bean

注意

@SpringBootApplicationscan的BasePackages属性不配置的话会默认扫描本类包内及子类包内的bean，如果配置了BasePackages则不会扫描本类包内及子类包内的bean

2.@ComponentScan

@ComponentScan(basePackages = "cn.mypackage1","cn.mypackage1")
public class Application {

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

}

这个注解的使用方法和SpringBootApplication基本一致

3.@Import

@Import(LogAspect.class)
public class Application {

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

}

如果希望引入包里的某一个bean，而不想引入该包下的全部bean，可以使用@Import注解

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Import({SchedulingConfiguration.class})
@Documented
public @interface EnableScheduling {
}

例如，springboot启动定时器也是使用了Import注解
