By default, when serializing objects, Jackson will auto-detect all public no-argument non-static getter methods and include them as properties in the final result (JSON string). I wanted Jackson to use only annotated methods and ignore rest of the methods of my object. To accomplish this we need to turn off the AUTO_DETECT_GETTERS feature in SerializationConfig object by configuring our ObjectMapper which holds an instance of SerializationConfig. I couldn't manage to inject a preconfigured SerializationConfig or ObjectMapper object. Then I found out that we need create an ObjectMapper provider class that implements ContextResolver, and annotate it with @Provider. This provider should then return an instance of ObjectMapper. This is where we will configure the object.

This happens because Jersey cannot or doesn't know how to find Resource classes. Jersey has to be told the package name in which Resource classes are located. The most obvious way is to add an init-param to the web.xml file. But since I'm using Guice servlets, I wanted to do it in Guice-way.
