PM> Install-Package ExpressAOP### Test case You can define a fillter like this:
public class MyFilter : AOPFilterAttribute
{
private readonly string _key;
public MyFilter(String key)
{
_key = key;
}
protected override void Executing(IProcesser processer)
{
Setting.List.Add("Executing-" + _key);
}
protected override void Executed(IProcesser processer)
{
Setting.List.Add("Executed-" + _key);
}
}eg: You have a class like following:
class MyClass {
public void Foo1()
{
}
}And you want the filter is working on the Method. You have 2 methods to use the filter;
[AOPProxy]// Use the AOP
class MyModel2 : ContextBoundObject// baseclass
{
[MyFilter(":filter")]//AFilter
public void Foo1()
{
Setting.List.Add("method");
}
}I write a test case for this way:
[TestMethod]
public void ClassContextBoundObject()
{
var o = new MyModel2();
o.Foo1();
Assert.AreEqual(new[]
{
"Executing-:filter",
"method",
"Executed-:filter"
}.GetStr(), Setting.List.GetStr());
}It'll be working well.
You must impl a interface for your class
public interface IMyModel
{
void Foo(int i);
}
public class MyModel : IMyModel
{
private readonly string _key;
public MyModel(string key)
{
_key = key;
}
[MyFilter("method:filter")]
public void Foo(int i)
{
Setting.List.Add("method-foo-" + _key);
}
}And use this code:
var proxy = new AOPProxy<IMyModel>(new MyModel("1"));
var obj = proxy.GetObject();
obj.Foo(1);It'll be running.
You can use Filter like this:
[MyFilter("I:filter")]
public interface IMyModel
{
[MyFilter("I-Method1:filter")]
[MyFilter("I-Method2:filter")]
void Foo(int i);
string MyProperty
{
[MyFilter("I-prop-get:filter")]
get;
}
}
[MyFilter("class:filter")]
public class MyModel : IMyModel
{
private readonly string _key;
public MyModel(string key)
{
_key = key;
}
[MyFilter("method:filter")]
public void Foo(int i)
{
Setting.List.Add("method-foo-" + _key);
}
public string MyProperty
{
[MyFilter("prop-get:filter")]
get
{
Setting.List.Add("prop-ins-" + _key);
return _key;
}
}
}Execute Order is
| Order | Description |
|---|---|
| 1 | The Filter on Interface |
| 2 | The Filter on Class |
| 3 | The Filter on Interface's Method or Property |
| 4 | The Filter on Class 's Method or Property |
| 5 | Method or Property |
