Allow SpEl expressions to be evaluated from JSPs [SPR-6827] #11493
Description
Keith Donald opened SPR-6827 and commented
As a user, I would like to be able to evaluate SpEL expressions from my JSPs to take advantage of all that SpEL has to offer, such as the ability to invoke methods on Java objects. The EvaluationContext should expose access to the same variables standard EL expressions have access to, such as page scope and request scope.
We should look at a dedicated spring:eval tag for this, as well as opportunities to directly hook into the JSP engine itself so standard ${exp} syntax can be used for evaluating SpEL expressions.
Affects: 3.0 GA
