ABP framework

ABP Framework Basics

ABP Is an open source and document friendly application framework .ABP It's not just a framework , It also provides a practical Domain Driven Design (DDD) The architecture model of , Can support .net framework and .net core Two technical schools .

ABP Frame features

• Dependency injection , This part uses Castle windsor （ Dependency injection container ） To implement dependency injection , This is also what we often use IOC To deal with the way ;
• Repository Storage mode , Has been realized. Entity Framework、NHibernate、MangoDB、 Memory database, etc , The storage mode can realize the call of data interface quickly ;
• Authentication and authorization management , You can use the declaration feature to log in to the user or not , Or verify the permission of the interface , In a very fine-grained way , Set the call permission of each interface ;
• Data validation ,ABP Automatically judge the input parameter object of the interface , And the validity of the attribute can be verified according to the application information of the attribute ;
• Audit logs , That is to record our call records for each interface , And the creation of records 、 modify 、 Delete personnel for records and other processing ;
• Unit Of Work Work unit mode , Automatically implement database transactions for application layer and storage layer methods , Default interface of all application service layers , They all work in units of work , Even if they call different storage objects to handle , They are all in the logic of a transaction ;
• exception handling ,ABP The framework provides a complete set of process processing operations , It is very convenient to record and pass exceptions ;
• logging , We can use Log4Net Do regular logging , It's convenient for us to track the program processing information and error information ;
• Multilingual / Localization support ,ABP The framework is also friendly to multi language processing , Provide for the right to XML、JSON Language information configuration processing ;
• Auto Mapping Automatic mapping , This is ABP An important concept of object isolation , By using AutoMaper To implement domain objects and DTO Property mapping of objects , Can isolate the logical relationship between the two , But it can easily realize the assignment of attribute information ;
• dynamic Web API layer , Take advantage of this dynamic processing , You can put Application Service Direct release as Web API layer , There is no need to manually create one for each business object Web API The controller , Very convenient ;
• dynamic JavaScript Of AJax Agent processing , Can automatically create Javascript The agent layer is more convenient to use Web Api, This is in Web Layer using .

ABP Special features of the framework

• Multi tenant support （ Each tenant's data is automatically isolated , Business module developers do not need to write code when saving and querying data ;
• Soft delete support （ Inherit the corresponding base class or implement the corresponding interface , Soft deletion will be realized automatically ）
• System settings access management （ The system level 、 Tenant level 、 User level , Scope of action automatic management ）
• EventBus Implement domain events (Domain Events)
• Modules and module dependencies to achieve plug-in module processing and so on

ABP Framework hierarchical architecture diagram

The idea of separation between the front and the back , Not only can it be applied to Web Of B/S Development , Apply to both C/S Development

• front end Web The end can use Ant-Design(React)、IView（VUE）、Angular And so on different front-end technology to carry the interface presentation layer
• front end Client The desktop side can use MaterialDesign design code , according to Prism perhaps MVMMLight Of MVMVM Framework combined with application

WEB API Priority Architecture

ABP The core of the framework is mainly .NET The back-end technology stack is the main line , although ASP.NET CORE MVC and Web API It's divided into two parts , But his dynamic release is Web API Limited architecture provides better convenience .

In today's popular presentation layer , More and more independent of the back-end technology implementation , And focus on Web API Standardized docking , be based on JSON Interactive processing of data . No matter what it is Ant-Design(React)、IView（VUE）、Angular And so on Web front end , We can see that these architectures are easy to implement Web API Standard interface docking , In my earlier offer of Winform Inside the hybrid frame , Also with Web API Priority strategy for Cloud Application Deployment

ABP The project structure of the framework

ABP The framework consists of two parts , A basic ABP frame , One ABP Extended applications based on the basic framework . It provides personnel 、 role 、 jurisdiction 、 conversation 、 Authentication 、 multi-tenancy 、 Logging and so on , We generally mean ABP Framework application is to expand its business project on this basis . This part , We can configure certain options according to the official website , Then download and use .

The template style of extension application is as follows , You need to download it from the official website

download .net core After the project , The project view of the back-end part is as follows

We can see from this project , It is mainly divided into the following several project layers .

• Application application layer ： The application layer provides some application services （Application Services） Method is called by the presentation layer . An application service method receives a DTO( Data transmission object ) As input parameter , Use this input parameter to perform specific domain level operations , And return to another... As needed DTO.

• Core Domain core layer , The domain layer is the business layer , Is the core of a project , All business rules should be implemented at the domain level . In this project , In addition to defining the required domain entity classes , In fact, we can define our own custom warehousing objects （ similar DAL/IDAL）, And define your own business logic layer （ similar BLL/IBLL）, And based on AutoMapper Mapping rules and so on .

• EntityFrameworkCore The core layer of Entity Framework , This project doesn't need to change much , Only need DbContext The storage object of the corresponding domain object can be added .

• Migrator Data migration layer , This is a console program project created by assistant , If based on DB First, We can use it to create our project's initialization database .

• Web.Core Web Core layer , be based on Web perhaps Web API The core layer of , Provides the basic processing of authentication login , Nothing else .

• Web.Core.Host Web API The host layer of , It's also a dynamic release Web API The core content , In addition to Web API It's integrated Swagger, Make it convenient for us to Web API Debug the interface of .

• Tests Unit test layer , This provides some simulation tests of application layer objects , The database tested uses Entity Framework Memory database of , Does not affect the actual database content .
