1、自定义注解@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Import({InitSpringListener.class})
public @interface EnableTest {
}2、spring boot加上自定义的注解
@Slf4j
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableTest
public class TestApplication {public static void main(String[] args) {SpringApplication app = new SpringApplication(TestApplication.class);ApplicationContext ctx = app.run(args);}
}启动所调用的类
@Slf4j
public class InitSpringListener implements ApplicationListener<ApplicationReadyEvent> {@SneakyThrows@Overridepublic void onApplicationEvent(ApplicationReadyEvent event) {ApplicationContext applicationContext = event.getApplicationContext();Map<String, Object> serviceMap = applicationContext.getBeansWithAnnotation(Service.class);for (Map.Entry<String, Object> entry : serviceMap.entrySet()) {Object obj = entry.getValue();// 从spring容器取出来的，被包了一层代理，此刻需要进行解析if (AopUtils.isAopProxy(obj)) {if (AopUtils.isJdkDynamicProxy(obj)) {Field h = obj.getClass().getSuperclass().getDeclaredField("h");h.setAccessible(true);AopProxy aopProxy = (AopProxy) h.get(obj);Field advised = aopProxy.getClass().getDeclaredField("advised");advised.setAccessible(true);obj = ((AdvisedSupport) advised.get(aopProxy)).getTargetSource().getTarget();} else {// 属性为 CGLIB$CALLBACK_0 即是生成的 dynamicAdvisedInterceptor 对象Field h = obj.getClass().getDeclaredField("CGLIB$CALLBACK_0");h.setAccessible(true);Object dynamicAdvisedInterceptor = h.get(obj);// dynamicAdvisedInterceptor 中属性为 advised 则是最终被代理的对象Field advised = dynamicAdvisedInterceptor.getClass().getDeclaredField("advised");advised.setAccessible(true);obj = ((AdvisedSupport) advised.get(dynamicAdvisedInterceptor)).getTargetSource().getTarget();}}assert obj != null;Class<?> clazz = obj.getClass();final Method[] methods = ReflectionUtils.getUniqueDeclaredMethods(clazz);for (Method method : methods) {System.out.println(method.getName());}}}}
