ravendb源代码学习一：服务启动

本质似乎就是一个asp.net core的httpapi

namespace Raven.Server
{
    public sealed class RavenServerStartup
    {
        private RequestRouter _router;
       //部分代码
        public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
        {
          _router = app.ApplicationServices.GetService<RequestRouter>();
          app.Use(_ => RequestHandler);
       }
    
        private async Task RequestHandler(HttpContext context)
        {  //...
                sp = Stopwatch.StartNew();
                await _router.HandlePath(requestHandlerContext).ConfigureAwait(false);
                sp.Stop();            
        }
    }
}

RequestRouter 的初始化在

namespace Raven.Server
{
    public sealed class RavenServer : IDisposable
    {
       public void Initialize()
       {
          Router = new RequestRouter(RouteScanner.AllRoutes, this);
          //...
          var webHostBuilder = new WebHostBuilder()
                   .UseStartup<RavenServerStartup>()                    
                    .ConfigureServices(services =>
                    {
                        //...
                        services.AddSingleton(Router);
                     }      

RouteScanner.AllRoutes的类一般都在Raven.Server.Documents.Handlers名字空间下

namespace Raven.Server.Documents.Handlers
{
    public sealed class DocumentHandler : DatabaseRequestHandler
    {
        //....
        [RavenAction("/databases/*/docs", "GET", AuthorizationStatus.ValidUser, EndpointType.Read)]
        public async Task Get()
        {
            using (var processor = new DocumentHandlerProcessorForGet(HttpMethod.Get, this))
            {
                await processor.ExecuteAsync().ConfigureAwait(false);
            }
        }

这就是我们使用RavenDb.Client中Load<T>的实际处理的入口
