我目前正在使用 Castle DynamicProxy 实现拦截器。我需要拦截器在我的服务层方法上获取一些自定义属性,但 invocation.Method.GetCustomAttributes 什么也不返回。有什么我可能做错了吗?
截取方法:
[Transaction()]
[SecurityRole(AuthenticationRequired = false, Role = SystemRole.Unauthorised)]
public virtual void LoginUser(out SystemUser userToLogin, string username)
{
...
}
拦截器:
// Checks that a security attribute has been defined
foreach (SecurityRoleAttribute role in invocation.Method.GetCustomAttributes(typeof(SecurityRoleAttribute), true))
{
if (!securityAttributeDefined)
securityAttributeDefined = true;
}
我也试过:
Attribute.GetCustomAttribute(invocation.Method, typeof(SecurityRoleAttribute), true);
更新:
可能是配置问题。配置代码如下:
拦截器安装程序:
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(
Component.For<LoggingInterceptor>()
.Named("LoggingInterceptor"));
container.Register(
Component.For<SecurityInterceptor>()
.Named("SecurityInterceptor"));
container.Register(
Component.For<ValidationInterceptor>()
.Named("ValidationInterceptor"));
}
服务安装程序:
public void Install(IWindsorContainer container, IConfigurationStore store)
{
string[] interceptors = {"LoggingInterceptor", "SecurityInterceptor"};
container.Register(AllTypes.FromAssemblyContaining<BaseService>().Pick()
.If(Component.IsInSameNamespaceAs<LoginService>())
.Configure(c => c
.LifeStyle.Transient
.Interceptors(interceptors))
.WithService.DefaultInterface());
}
我正在使用 Castle 2.5.2/.Net 3.5。
谢谢,
