Refactor InternalResourceView to expose getRequestDispatcher for overriding [SPR-7118]

[spring-projects-issues]

Kenny MacLeod opened SPR-7118 and commented

InternalResourceView obtains the RequestDispatcher within the renderMergedOutputModel. Please refactor this so that this logic to done by a protected getRequestDispatcher method, allowing subclasses to override the means by which the RequestDispatcher is located.

Use case: getting the RequestDispatcher from a different ServletContext.

Affects: 3.0.2

Good idea. I've factored out a protected getRequestDispatcher template method for 3.0.3.
