如何强制安装程序执行的顺序

Ada*_*art 8 dependency-injection castle-windsor inversion-of-control c#-4.0

我一直在构建一个新的.NET解决方案,而Castle正在执行我的DI.

它现在处于我想控制我的安装程序运行顺序的阶段.我已经构建了单独的类来实现IWindsorInstaller来处理我的核心类型 - 例如IRepository,IMapper和IService等等.

我看到它建议我在这个类中实现我自己的InstallerFactory(猜测我只是覆盖Select).

然后在我的电话中使用这个新工厂:

FromAssembly.InDirectory(new AssemblyFilter("bin loca­tion"));

我的问题 - 覆盖保存方法时 - 强制安装程序顺序的最佳方法是什么.

我知道它已经解决但我找不到任何关于如何实际实现InstallerFactory的例子,所以这里是一个解决方案,如果有人在谷歌上搜索它.

如何使用:

[InstallerPriority(0)]
    public class ImportantInstallerToRunFirst : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, Castle.MicroKernel.SubSystems.Configuration.IConfigurationStore store)
        {
            // do registrations
        }
    }

只需将InstallerPriority具有优先级的属性添加到"安装顺序敏感"类中.安装程序将按升序排序.没有优先权的安装程序将默认为100.

如何实施:

public class WindsorBootstrap : InstallerFactory
    {

        public override IEnumerable<Type> Select(IEnumerable<Type> installerTypes)
        {
            var retval =  installerTypes.OrderBy(x => this.GetPriority(x));
            return retval;
        }

        private int GetPriority(Type type)
        {
            var attribute = type.GetCustomAttributes(typeof(InstallerPriorityAttribute), false).FirstOrDefault() as InstallerPriorityAttribute;
            return attribute != null ? attribute.Priority : InstallerPriorityAttribute.DefaultPriority;
        }

    }


[AttributeUsage(AttributeTargets.Class)]
    public sealed class InstallerPriorityAttribute : Attribute
    {
        public const int DefaultPriority = 100;

        public int Priority { get; private set; }
        public InstallerPriorityAttribute(int priority)
        {
            this.Priority = priority;
        }
    }
