使用自定义注释的组件扫描 [英] Component scan using custom annotation
本文介绍了使用自定义注释的组件扫描的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在使用 maven 依赖项在另一个 spring boot 应用程序中将 spring boot 项目作为 jar 使用.仅当我启用来自微服务的自定义注释时,我才想对 jar 进行组件扫描.
I am consuming a spring boot project as jar inside another spring boot application using the maven dependency. I want to do the component scan of jar only if I enable a custom annotation from microservice.
@SpringBootApplication
//@ComponentScan({"com.jwt.security.*"}) To be removed by custom annotation
@MyCustomAnnotation //If I provide this annotation then the security configuration of the jar should be enabled.
public class MicroserviceApplication1 {
public static void main(String[] args) throws Exception {
SpringApplication.run(MicroserviceApplication1.class, args);
}
}
请提出一些想法.
推荐答案
在你的图书馆:
@Configuration
@ComponentScan(basePackages = { "com.jwt.security" })
public class MyCustomLibConfig{
}
@Retention(RUNTIME)
@Target(TYPE)
@Import(MyCustomLibConfig.class)
public @interface MyCustomAnnotation{
@AliasFor(annotation = Import.class, attribute = "value")
Class<?>[] value() default { MyCustomLibConfig.class };
}
因此,在您的应用程序中,您可以使用注释
So, in your application you can use the annotation
@SpringBootApplication
@MyCustomAnnotation //If I provide this annotation then the security configuration
of the jar should be enabled.
public class MicroserviceApplication1 {
public static void main(String[] args) throws Exception {
SpringApplication.run(MicroserviceApplication1.class, args);
}
}
