Struts 2 Interview Questions


Struts 1.x vs Struts 2.x Main Differences



 In struts 1  front controller is ActionServlet
        In 2.x front controller is FilterDispatcher

    In struts 1.x we have RequestProcessor class
        In 2.x we have Interceptors instead RequestProcessor will see about this concept later just remember as of now

    In struts 1.x we have multiple tag libraries like, html, logic, bean..etc
        In 2.x we do not have multiple libraries, instead we have single library which includes all tags

    In struts 1.x the configuration fine name can be [any name].xml and we used to place in web-inf folder
        In 2.x the configuration file must be struts.xml only and this must be in classes folder

    In struts 1.x we have form beans and Action classes separately
        In 2.x form bean, Action classes are combinedly given as Action class only, of course we can take separately if we want ;)

    In struts 1.x properties file must be configured in struts-config.xml
        But in 2.x we need to configure our resource bundle(s) in struts.properties file

    In struts 1.x we have programmatic and declarative validations only
        In 2.x we have annotations support too along with programmatic and declarative validations
