Understand the basics of the ABP framework

What is the ABP framework, specific code examples are required

ABP (Application Boilerplate Platform) is an open source application framework designed to simplify and accelerate enterprise-level applications Program development process. It includes a set of best practices, tools and standard patterns, allowing developers to focus more on the implementation of business logic without having to spend too much time and energy on infrastructure and repetitive work.

The ABP framework uses ASP.NET Core as its foundation, and combines domain-driven design (DDD), dependency injection, aspect-oriented programming, modularization and other design concepts. Through the combination of these concepts, the ABP framework provides an efficient, scalable, and maintainable architecture, providing developers with a better development experience.

In the ABP framework, applications are organized into one or more modules, and each module can be independently developed, tested, and deployed. Each module can contain its own domain model, application services, warehousing, Web API and other components, and has good modular characteristics.

Let’s look at a specific code example to show the application of the ABP framework.

First, we create a new ABP solution using the ABP CLI tool or Visual Studio template. Here we take Visual Studio as an example.

In Visual Studio, choose to create a new project, select "ABP Application Template", define the solution name and location, and click "OK" to create the solution.

In the solution, we can see that a main project and a shared module have been created.

Next, we create a domain model in the shared module. In the domain model, a simple entity class is defined:

public class Book : Entity<Guid>
{
    public string Title { get; set; }
    public string Author { get; set; }
    public decimal Price { get; set; }

    public Book(Guid id, string title, string author, decimal price)
        : base(id)
    {
        Title = title;
        Author = author;
        Price = price;
    }
}

Then, we create an application service in this module for adding, deleting, modifying and checking books:

public class BookAppService : ApplicationService
{
    private readonly IRepository<Book, Guid> _bookRepository;

    public BookAppService(IRepository<Book, Guid> bookRepository)
    {
        _bookRepository = bookRepository;
    }

    public async Task CreateBook(CreateBookInput input)
    {
        var book = new Book(Guid.NewGuid(), input.Title, input.Author, input.Price);
        await _bookRepository.InsertAsync(book);
    }

    public async Task<List<Book>> GetAllBooks()
    {
        return await _bookRepository.GetAllListAsync();
    }

    // 其他操作方法...
}

Finally , create a Web API controller in the main project to accept front-end requests and call application services:

public class BookController : AbpController
{
    private readonly BookAppService _bookAppService;

    public BookController(BookAppService bookAppService)
    {
        _bookAppService = bookAppService;
    }

    [HttpPost]
    public async Task<IActionResult> Create(CreateBookInput input)
    {
        await _bookAppService.CreateBook(input);
        return Ok();
    }

    [HttpGet]
    public async Task<IActionResult> GetAll()
    {
        var books = await _bookAppService.GetAllBooks();
        return Ok(books);
    }

    // 其他接口方法...
}

Through the above code examples, we can see the basic application process of the ABP framework. In the ABP framework, we organize applications in a modular manner, use domain-driven design to define domain models, implement business logic operations through application services, and finally interact with the front-end through Web API controllers.

The ABP framework provides a wealth of features and tools, such as authentication and authorization, multi-tenant support, localization, logging, etc., allowing developers to more easily build powerful and highly reliable enterprise-level applications. program.

In short, the ABP framework makes the development of enterprise-level applications more efficient and maintainable by providing a set of best practices, tools, and standard patterns. Using the ABP framework, developers can focus more on the implementation of business logic without having to spend too much time and energy on infrastructure and repetitive work.
