Spring MVC DispatcherServlet initialization parameter contextClass in documentation should implement ConfigurableWebApplicationContext not WebApplicationContext [SPR-17414] #21947
Description
Sun Tao opened SPR-17414 and commented
In section 22.2.3 table 22.2, the explanation for contextClass Paramter is "Class that implements WebApplicationContext ..."
But when I see the source code of FrameworkServlet, the method createWebApplicationContext will throw exception if ConfigurableWebApplicationContext is not a super class of contextClass. So is it better to say contextClass should implement ConfigurableWebApplicationContext?
Thank you.
Affects: 4.3.18

Indeed, with the default context loading algorithm in
FrameworkServlet/DispatcherServlet, the context class needs to implementConfigurableWebApplicationContext. Only with a custom subclass ofDispatcherServlet, other kinds ofWebApplicationContextcould be used.
