Spring Add support for custom expression parsing in CachedExpressionEvaluator

When I use CachedExpressionEvaluator, i need parseContext to influence an expression, so add ParseContext param

Thanks for the PR. Rather than making an extra method, I am wondering if we couldn't add a protected method that does the parsing of the expression instead. Would that work if you would override that method with the parser context?

the class ExpressionKey is protected and the createKey method is default. override not work. I think add a method is more More appropriate.

Thanks but I am not talking about that. More about a protected method where you could control how parsing is done, something like:

protected Expression parseExpression(String expression)

that you could override to provide the additional context.
