Java获取泛型实际类型

@Service
public class ImformationModelEsServiceImpl extends BaseEsService<ImformationModuleEsEntity{
}

问：如何获取ImformationModelEsServiceImpl类中的泛型ImformationModuleEsEntity?

答:

Type genericSuperclass = this.getClass().getGenericSuperclass();
if (genericSuperclass instanceof ParameterizedType){
  ParameterizedType parameterizedType = (ParameterizedType) genericSuperclass;
  Type[] actualTypeArguments = parameterizedType.getActualTypeArguments();
  for (Type actualTypeArgument : actualTypeArguments) {
    System.out.println(actualTypeArgument);
  }
}
