如何在类中获取类型参数的擦除类型

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

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

public class MyClass<T> {
    private Class<T> type;

    public MyClass(Class<T> type) {
        this.type = type;
    }

    public Class<T> getType() {
        return type;
    }
}
