repository-pattern | Repository 模式範例碼

I try to follow this tutorial : https://www.thinktocode.com/2018/03/05/repository-pattern-symfony/.

It's suppose to help structure your Repository.

But when i get to this point :

I inherited a project, and asked to implemented Paging across all our Repositories (500+ methods), to show only segments of data on web front end.

Current Repository is below as following. They return Task Lists, IEnumerables etc .

How would we go through, and implement paging for the following Repositories examples?

If I implement following Paged List answer, the repos return IList, not IQueryable. So the answer, would still Retrieve All the Data first (causing performance issue), and then filter it.

Repository:

I have a repository class in my Flutter app with the following method that returns a Stream:

I'm having an issue with deserializing a collection from MongoDB. It seems fine for a single object but fails for a collection of objects. The collection is a GeoJSON object in Mongo with coordinates. That seems to be the problem. Perhaps I'm not representing that right in my C# class. Though it seems to work fine for a single object.

I created a generic collection repo according to this post: Generic Mongo Repository pattern implemented in .NET Core

Given my class:

I followed a tutorial on Generic Repository Pattern with ASP.NET core with EF CORE, here for example

I have a Dao class which returns List of Car objects as flow.

I have a Symfony and Spring background, this is my first project with Laravel and as far as I understood Laravel doesn't have a build-in support for repositories. I found several tutorials; some of them try to offer architecture like Spring or Symfony.

As an example this blog suggests an folder structure like this:

I am trying to find a way I can implement the repository pattern using spring boot with Generic types. So far I looked into this article:

https://thoughts-on-java.org/implementing-the-repository-pattern-with-jpa-and-hibernate/

and tried implementing this solution using generic types based on the solution to this question:

Using generics and jpa EntityManager methods

I attempted to do so using JPA and Hibernate but for me, an error appears when I try returning the class of the entity on the specified type parameter.

the following is my User model using JPA and Hibernate:

I currently am building a rest API with asp net core. I was following this tutorial from Medium, which is a tutorial about Repository pattern implementations. Here is the Link.

I have 2 superclasses, each one has a subclass. I have Superclass TController and TService and the subclasses UserController and UserService. I want to call from UserController a method of UserService. The method is defined in UserService but not in the superclass of TService.

So my question is: How can you execute a method set in UserController, when you are calling it from UserController?

Here is the controller:
