使用@Enable注解4个

使用@import（）将Javabean导入Spring容器中

@SpringBootApplication

@ComponentScan

@Async//异步处理。bean 类之上

//@EnableAsync使异步处理生效

//@Import({User.class,Role.class,MyConfiguration.class})//可以导入一个类，或者多个类

@Import({MyImportSelector.class})//使用importSelector的实现类进行设置，引入实现类对bean进行装配

importSelector的返回值必须是一个类的全程，该类会被Spring容器所托管

public class App {

public static void main(String[] args) {

ConfigurableApplicationContext context=SpringApplication.run(App.class, args);

System.out.println(context.getBean(User.class));

System.out.println(context.getBean(Role.class));

//System.out.println(context.getBeansOfType(Runnable.class));

context.close();

}

}

public class MyImportSelector  implements ImportSelector{

@Override

public String[] selectImports(AnnotationMetadata importingClassMetadata) {

// TODO Auto-generated method stub

return new String[] {

"com.lsq.springboot.User",

"com.lsq.springboot.Role"

};

}

}
