我写了一篇类似的帖子(Castle Windsor won't inject Logger in a property!),但没有人能提供解决方案,所以我在这里准备了一个简单的完整代码示例:
using Castle.Core.Logging;
using Castle.Facilities.Logging;
using Castle.MicroKernel.Registration;
using Castle.MicroKernel.SubSystems.Configuration;
using Castle.Windsor;
namespace IocTest
{
public class LoggerInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.AddFacility("logger", new LoggingFacility(LoggerImplementation.Log4net, "log4net.config"));
}
}
public class LogicInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(AllTypes.FromThisAssembly()
.Pick()
.If(t => t.Name.StartsWith("Logic"))
.Configure((c => c.LifeStyle.Transient)));
}
}
class Program
{
static void Main(string[] args)
{
IWindsorContainer container = new WindsorContainer();
container.Install(
new LoggerInstaller(),
new LogicInstaller()
);
LogicClass1 logic1 = container.Resolve<LogicClass1>();
LogicClass2 logic2 = container.Resolve<LogicClass2>();
}
}
public class LogicClass1
{
private ILogger logger = NullLogger.Instance;
public ILogger Logger
{
get { return logger; }
set { logger = value; }
}
public LogicClass1()
{
logger.Debug("Here logger is NullLogger!");
}
}
public class LogicClass2
{
public LogicClass2(ILogger logger)
{
logger.Debug("Here logger is properly injected!");
}
}
}
出了什么问题?
