Camel: getting current route's exchange without specfying exchange as parameter

When I work with Camel almost every method I write has Exchange as a parameter, in order to get the current exchange by automatic binding.

Something like that:

class MyClass
{
    void doSomething(Exchange exchange, ........)
    {
        exchange.getIn().....

        .......
    }
}

Is there a way to get the current exchange without specifying it as a parameter?

Maybe something like this....?

class MyClass
{
    @ExchangeAware
    Exchange exchange;

    void doSomething(........)
    {
        exchange.getIn().....

        .......
    }
}
