A bit of an update (if anybody is even following this!). I've pushed some more changes to my fork ( https://github.com/Orkie/spring-framework/tree/SPR-11530).
I've added the attribute 'immutable-properties' which tells the dynamic language post processor to intercept/resolve the properties and pass them into the factory code before the script is executed. These are then bound to a map which you reference with *spring-bindings*. I'm a lot happier with this approach from a Clojure point of view, but I'm not sure how elegant it is in terms of how the Spring code is written: there is essentially one large, hand-written DOM parser, and it wasn't designed to be extended like this. To add a new tag which behaves broadly the same way as property (which is what I want) would be a huge amount of work, and I'm also having to fiddle with the bean factory slightly to allow it to resolve properties-like objects without doing all the other property stuff (setting internal spring state, calling setters etc.). I'm going to try and get some feedback from one of the Spring guys to see what they think. As it stands, you would now to something like this.. Spring XML context: <lang:clojure id="calculator" immutable-properties="true"> <lang:inline-script> (reify org.springframework.scripting.Calculator (add [this x y] (+ x y))) </lang:inline-script> </lang:clojure> <lang:clojure id="messenger" script-source="classpath:org/springframework/scripting/clojure/Messenger.clj" immutable-properties="true"> <lang:property name="message" value="Hello World!"/> <lang:property name="thecalc" ref="calculator" /> </lang:clojure> classpath:org/springframework/scripting/clojure/Messenger.clj: (ns Messenger) (def my-calculator (get *spring-bindings* "thecalc")) (def the-message (get *spring-bindings* "message")) (reify org.springframework.scripting.Messenger (getMessage [this] (str the-message (.add my-calculator 4 9)))) On Saturday, 8 March 2014 16:10:56 UTC, Adan Scotney wrote: > > Hi, > > I have a Java project which uses Spring to wire together various services, > and the only way I've managed to find to integrate Clojure services > (without using gen-class) is to have something resembling the > MethodInvokingFactoryBean, or to manually write a wrapper which calls out > to Clojure.
