没有限定名称的Java反射

首先，使用Reflections库获取所有类

 Reflections reflections = new Reflections(); Set<Class<?>> allClasses = reflections.getSubTypesOf(Object.class);

接下来，建立一个查找映射。

// Doesn't handle collisions (you might want to use a multimap such as http://docs.guava-libraries.googlepre.com/git/javadoc/com/google/common/collect/Multimap.html instead)Map<String, Class<?>> classBySimpleName = new HashMap<>();for(Class<?> c : allClasses) {    classBySimpleName.put(c.getSimpleName(), c);         }

当您需要查找课程时，您可以执行以下操作：

Class<?> clazz = classBySimpleName.get(className);
