获取泛型类对应的class类型
自己写来备忘的,如有错误,请指正!
public class Demo<T> {
private Class<T> clazz;
public Demo() {
ParameterizedType parametclass = (ParameterizedType) this.getClass().getGenericSuperclass();
Type[] actualTypeArguments = parametclass.getActualTypeArguments();
clazz = (Class<T>) actualTypeArguments[0];
}
}
