java - How to get DI working with Guice and Webapps? -

how di work in webapp? far i've done following:

1) annotate setter method @inject

2) extend abstractmodule binds interface class implementation class attribute setter annotated in step 1

3) extend guicecontextservletlistener , overrode getinjector returns guice.createinjector(new extendedabstractmodule())

4) registered extended guicecontextservletlistener in web.xml listener

i've verified extended guicecontextservletlistener.getinjector() method called when webapp started. attribute setter annotated not being injected , remains null.

i went ahead , created servletmodule serves servlet instantiates object @inject setter. after instantiating object injector servletcontext , call injectmembers method passing instantiated object.
