Description
Dave Syer opened BATCH-1686 and commented
Spring Integration and has some useful utility classes that are used to interpret SpEL expressions. Spring MVC also provides some inspiration (though not using SpEL) in the adaptable method signatures for controllers. Spring Batch listeners and one-line declarative helpers could be implemented uniformly using SpEL as a building block for parsing and evaluation.

Research direction
Start by reading the two referenced commits, then examine the Spring Integration utility classes for SpEL interpretation and the Spring MVC adaptable method-signature approach mentioned in the issue. The work is done when Spring Batch listeners and one-line declarative helpers use a uniform SpEL-based mechanism for parsing and evaluation.
