Java 自定义注解简单使用
Java 自定义注解简单使用 第一步：在 pom.xml 下引入反射框架 <dependency> <groupId>org.reflections</groupId> <artifactId >reflections</artifactId> <version>0.10.2</version> </dependency> 第二步：自定义注解 package com.zibo.api.annotation 第四步：写个工具类扫描被注解的类（核心） package com.zibo.api.utils; import com.zibo.api.annotation.MyConfig; import org.reflections.Reflections new LinkedHashMap<>(); // 要扫描的包 String packageName = "com.zibo.api.entity"; Reflections f = new Reflections(packageName); // 获取扫描到的标记注解的集合 Set<Class<?

Java动态获取某个接口下所有的实现类对象集合
开始想着用反射自己写一个工具类，后面懒得去折腾，就直接用第三方工具包了 ， 这里我用的是org.reflections . maven配置： <dependency> <groupId>org.reflections </groupId> <artifactId>reflections-spring</artifactId> <version>${reflections.version}</version> 另外就是代码引用了，以DelayedBaseMonitor接口为例： List<DelayedBaseMonitor> monitorLists = new ArrayList<>(); Reflections reflections = new Reflections(delayedFindPackageName); Set<Class<? extends DelayedBaseMonitor>> monitorClasses = reflections.getSubTypesOf(DelayedBaseMonitor.class);

2018 MCM Problem A notes
(from one point on the earth’s surface to another distant point on the earth’s surface) by multiple reflections In this problem, the focus is particularly on reflections off the ocean surface. It has been found empirically that reflections off a turbulent ocean are attenuated more than reflections If additional reflections (2 through n) take place off calm oceans, what is the maximum number of hops (mss1) Part II: How do your findings from Part I compare with HF reflections off mountainous or rugged
