Various Spring MVC RequestMapping configuration questions

[balteo]

Hi,

I have several (albeit related) questions about Spring MVC RequestMapping configuration:

1. Say I have a type-level RequestMapping annotation as follows:

    @RequestMapping("/root/")

   What is the difference between adding this method-level RequestMapping:

   @RequestMapping(value="leaf")

   and that one?

   @RequestMapping(value="/leaf")

   Notice the leading slash in second method-level mapping.
   
   
2. What is the difference between having this type-level RequestMapping:

   @RequestMapping("/root/")

   and that one ?

   @RequestMapping("/root/*")

   Notice the star in second mapping.
   
   
3. Say I already have a type-level RequestMapping annotation. How do I override the type-level mapping at the method-level so that the type-level mapping is ignored (for a given controller)?

Regards,

Julien.

1. There should be no difference as they are combined.
2. It depends on your configuration, by default /root/ is mapped to /root/ and /root/*. /root/ matches only the index /root/* matches everything after /root/
3. No you cannot... They are always combined, class level is coarse grained and method level is finer grained.
