【问题描述】:
我正在使用 Topshelf 运行我的 wcf 服务和 Windsor castle 进行依赖注入。当我直接运行主机程序时出现问题,它作为控制台主机运行良好,但同一程序在尝试将其作为 Windows 服务启动时出现此错误。
Topshelf.Hosts.StartHost Error: 0 : The service failed to start., System.Invalid
OperationException: Cannot start service MyService on computer '.'. ---> Sy
stem.ComponentModel.Win32Exception: The service did not respond to the start or
control request in a timely fashion
--- End of inner exception stack trace ---
at System.ServiceProcess.ServiceController.Start(String[] args)
at System.ServiceProcess.ServiceController.Start()
at Topshelf.Runtime.Windows.WindowsHostEnvironment.StartService(String servic
eName, TimeSpan startTimeOut)
at Topshelf.Hosts.StartHost.Run()
下面是我的实现:-
class Program{
static void Main(string[] args)
{
var boot = new ServiceInstaller();
HostFactory.Run(x =>
{
x.Service<Program>(s =>
{
s.ConstructUsing(name => new Program());
s.WhenStarted(p => p.Start());
s.WhenStopped(p => p.Stop());
});
x.DependsOnMsSql();
x.StartAutomatically();
x.SetDisplayName("My Service");
x.SetServiceName("MyService");
});
}
public void Start()
{
try
{
_serviceProvider = typeof(IMyService).AssemblyQualifiedName;
LogMessage(LogLevel.INFO, _serviceProvider, null);
if (_serviceProvider == null)
{
throw new ArgumentNullException(string.Format(CultureInfo.InvariantCulture, "Failed to start service: {0}", _serviceProvider));
}
_serviceHost = new DefaultServiceHostFactory().CreateServiceHost(_serviceProvider, new Uri[0]);
_serviceHost.Open();
}
catch (Exception ex)
{
LogMessage(LogLevel.ERROR, "Error occurred while starting My Service", ex);
throw;
}
}
public void Stop()
{
try
{
_serviceHost.Close();
_serviceHost = null;
}
catch (Exception ex)
{
LogMessage(LogLevel.ERROR, "Error occurred while stopping My service ", ex);
throw;
}
}
}
public Class ServiceInstaller{
public static IWindsorContainer Container { get; private set; }
public ServiceInstaller()
{
try
{
Container = new WindsorContainer();
Container.Register(Component.For<IWindsorContainer>().Instance(Container));
Container.AddFacility<WcfFacility>().Register
(
Component.For<IDependency>().ImplementedBy<Dependency>().LifestyleTransient(),
Component.For<IMyService>().ImplementedBy<MyService>().LifestyleTransient()
);
}
catch (Exception ex)
{
throw;
}
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if (disposing)
{
if (Container != null)
{
Container.Dispose();
Container = null;
}
}
}
}
【问题讨论】:
-
可能 Start 中的代码在作为服务运行时会抛出异常。尝试在每条语句之后和第一条语句之前添加一条日志消息,以查看抛出了哪一行。
-
这可能是真的,但为什么它在通过 Visual Studio 调试或只是在 bin 文件夹中运行时运行良好。
-
您是否检查过 Windows 事件日志以查看那里是否记录了异常?
-
是的,这是记录到 Windows 事件日志中的异常 应用程序:MyServiceHost.exe 框架版本:v4.0.30319 描述:进程因未处理的异常而终止。异常信息:Castle.MicroKernel.ComponentActivator.ComponentActivatorException 堆栈:在 MyServiceHost.Program.Main(System.String[])
-
你能发布你的 Dependency 和 MyService 类吗?我怀疑问题出在他们身上。
