ABP.IO WEB應用程式框架屬性注入

2023-05-12

筆記下 ABP 中使用屬性注入

結論

TestAppService

public class TestAppService : TestDiAppService
{
    private readonly ITestManager _testManager { get; set; }
    
    public TestAppService(ITestManager TestManager)
    {
        _testManager = TestManager;
    }

    public Task<string> GetAsync()
    {
        return _testManager.GetAsync();
    }
}

一般使用建構式注入方式，由建構式參數傳入 ITestManager TestManager

屬性注入則不由建構式參數傳入 ITestManager TestManager

將 TestAppService(ITestManager TestManager) 改為 TestAppService()

並將欄位改成屬性 public ITestManager TestManager { get; set; }

TestAppService

public class TestAppService : TestDiAppService
{
    public ITestManager TestManager { get; set; }
    
    public TestAppService()
    {
        TestManager = new NullManager();
    }

    public Task<string> GetAsync()
    {
        return TestManager.GetAsync();
    }
}

ITestManager

public interface ITestManager : IDomainService
{
    Task<string> GetAsync();
}

NullManager

public class NullManager:ITestManager
{
    public Task<string> GetAsync()
    {
        return Task.FromResult("Null");
    }
}

TestManager

public class TestManager : DomainService, ITestManager
{
    public Task<string> GetAsync()
    {
        return Task.FromResult("Hello World");
    }
}
