Class ServletDeployer


  • public class ServletDeployer
extends Object

    Context listener that automatically registers Vaadin servlets. The servlets registered are:

    • Vaadin application servlet, mapped to '/*'
      The servlet won't be registered, if any VaadinServlet is registered already or if there are no classes annotated with Route annotation.
    • Static files servlet, mapped to '/VAADIN/static' responsible to resolve files placed in the '[webcontext]/VAADIN/static' folder or in the '[classpath]/META-INF/static' location. It prevents sensible files like 'stats.json' and 'flow-build-info.json' to be served. It manages cache headers based on the '.cache.' and '.nocache.' fragment in the file name.
    In addition to the rules above, a servlet won't be registered, if any servlet had been mapped to the same path already or if Constants.DISABLE_AUTOMATIC_SERVLET_REGISTRATION system property is set to true.
