问题
I'm writing a custom library that uses ServiceStack.Text internally. Other libraries that consume mine may also use ServiceStack.Text.
I want to change some JsConfig options (specifically date handling), but, like any good citizen, I don't want my modifications of those values to cause side effects for my consumer.
Unfortunately JsConfig is a static class, so its settings are static, and would bleed to other consumers of ServiceStack in the same AppDomain I believe. That's an undesired behavior.
Is there some way to scope my configuration changes to just my calls to the JsonSerializer?
Update
I do realize there is the JsConfig.Reset method, unfortunately if the caller has customized it already, that would be lost.
I could save values and restore them, but I would have to synchronize access to the serializer, which also kind of defeats the purpose.
Hopefully there is something simple I'm missing?
回答1:
This functionality was missing in ServiceStack.Text so I added a pull request for it.
Basically now if you wanted to scope your config settings you can use the following syntax:
using(var config = JsConfig.With(new Config { DateHandler = ... }))
{
}
And the values will no longer be set once the using block goes out of scope, its ThreadStatic as well so won't affect other threads.
回答2:
One possibility I've though of is just using a custom type internal to my library as the root object to serialize, and then specifying the JsConfig values specifically for that.
internal class MyInternalObject { }
JsConfig<MyInternalObject>.DateHandler = ...
I'm not sure if the root configuration values propagate down to child objects in the serialization, but easy enough to test.
