WPF实战学习笔记09-创建工作单元
创建工作单元
添加包
-
Microsoft.EntityFrameworkCore.AutoHistory
A plugin for Microsoft.EntityFrameworkCore to support automatically recording data changes history.
-
Microsoft.EntityFrameworkCore.UnitOfWork
A plugin for Microsoft.EntityFrameworkCore to support repository, unit of work patterns, and multiple database with distributed transaction supported.
依赖注入
添加命名空间using Arch.EntityFrameworkCore.UnitOfWork;
添加仓储段
添加文件
- webapi工程
./Repository/MemoRepository.cs
./Repository/ToDoRepository.cs
./Repository/UserRepository.cs
实现仓储段接口
注意要继承Repository, IRepository两个以及接口

添加测试数据
1. 数据库添加测试数据
2. 编写测试程序
-
WeatherForecastController（覆盖到对应的类中）
private readonly IUnitOfWork uow; public WeatherForecastController(ILoggerlogger,IUnitOfWork unitOfWork) { _logger = logger; this.uow = unitOfWork; } public IEnumerable Get() { //获取用户表 var service= uow.GetRepository (); var res = service.GetAll(); var rng = new Random(); }
