REST service actions and "normal" actions in the same web application (patch)
-----------------------------------------------------------------------------
Key: WW-3590
URL: https://issues.apache.org/jira/browse/WW-3590
Project: Struts 2
Issue Type: Improvement
Components: Plugin - REST
Affects Versions: 2.2.1.1
Environment: N/A
Reporter: Raigedas
Priority: Minor
Fix For: 2.2.2
Attachments: rest namespace patch.txt
Problem.
i would like to expand my existing webapp by adding RESTful ws. i do not want
to create a separate webapp which would serve solely as web service.
but as soon as i add REST plugin to th classpath of my struts2 based webapp,
all actions (which worked correctly before) stop working and i get errors:
java.lang.NoSuchMethodException <...> MyActionName.index().
i thought that it could be solved by reconfiguring "ActionMapper"s. i
configured that in this way:
<constant name="struts.mapper.class"
value="org.apache.struts2.dispatcher.mapper.PrefixBasedActionMapper"/>
<constant name="struts.mapper.prefixMapping" value="/ws/rest:rest,:struts"/>
but this does not solves the proble. "normal" actions throw "Cannot handle
CGLIB enhanced proxies with multiple callbacks"..
Solution.
i suggest to implement conditional enabling of the REST plugin. this can be
done by changing RestActionProxyFactory class a little bit. my solution (see
the patch) adds a "namespace" property (with setter only). that property has
default value or can have injected a config value named
"struts.rest.namespace". the default value is "/" which means that after update
the functionality of the plugin will remain the same unless one adds a config
like:
<constant name="struts.rest.namespace" value="/rest" />
