如何从Spring boot中的泛型参数(与任何类无关)中获取值

import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;

public class GenericParameterDemo<T> {

    public Class<?> getGenericType() {
        Type type = getClass().getGenericSuperclass();
        ParameterizedType parameterizedType = (ParameterizedType) type;
        Type[] typeArguments = parameterizedType.getActualTypeArguments();
        
        if (typeArguments.length > 0) {
            return (Class<?>) typeArguments[0];
        }
        
        return null;
    }

    public static void main(String[] args) {
        GenericParameterDemo<String> demo = new GenericParameterDemo<>();
        Class<?> genericType = demo.getGenericType();
        
        if (genericType != null) {
            System.out.println("Generic type: " + genericType.getName());
        } else {
            System.out.println("No generic type found.");
        }
    }
}
