## Examples
In some cases, we need to choose the right provider while the arguments of the 
method is setted.
The condition rule is like
> arguments[1].str!=b  => host = 1.1.1.1
While the str property of the second argument is equal to b, the providers 
whose host is equal to 1.1.1.1 is to be choosed。
We could use this feature to route requests according to business params.
