[Geoserver-devel] GWC and Spring 3.0.5

GeoServer GeoServer Developer
1

At the moment I try to migrate geoserver trunk to Spring 3.0.5 and Spring Security 3.0.5. Until now, the Spring migration is the easy part, Spring Security is much harder.

A mvn clean install runs all tests except some gwc tests.

Looking at

https://github.com/GeoWebCache/geowebcache/blob/master/geowebcache/pom.xml

I see that gwc uses Spring 2.5.5. How to continue ?

Cheers
Christian

Uh, that might be problematic, GWC should also do the switch to 3.0.5 I guess?
But it's up to the GWC developers to decide whether they want to switch, in what
time (afaik there are other modifications going) and who can look into it.

If I remember properly GWC makes a relatively lightweight usage of Spring, so
it may be that migrating it it's not that hard? Proposing a patch to switch GWC
to Spring 3.0.5 might be a good step forward (though, let's hear from Gabriel
about this).

Hi Christian,

migrating gwc to Spring 3 sounds good to me. If you feel like providing
a patch that'd be great, cause I'm not sure when I'll be able to do that
myself. For sure not before next week, though next week I think I could.

We use github:https://github.com/GeoWebCache/geowebcache
Or, to make things easier, you just need to migrate the context files in
the geoserver's gwc module, under src/main/resources, as gwc doesn't
come with them embedded in the jars (except for the gwc web module that
we don't depend on)

Cheers,
Gabriel

Solved, I had to modify

src/main/resources/geowebcache-geoserver-context.xml

and changed

<bean id="gwcFacade" class="org.geoserver.gwc.GWC">

to
<bean id="gwcFacade" class="org.geoserver.gwc.GWC" depends-on="gwowebCacheExtensions">

Now all tests pass.

At the moment I have an successful

mvn clean install -P allExtensions.

I will make some additional tests, open a JIRA issue and attach a patch.

Cheers
Christian
