Update: Now building a war archive containing a webapp directory.

spring-boot-example-wicket

This project builds and runs a minimal wicket web application.

Implemented:

fat war starting a tomcat server
wicket web application as spring boot starting point
using ServletContextInitializer instead of web.xml
spring wiring into wicket web pages
SpringBootServletInitializer used for optional deployment on application server

Notable classes

WicketWebApplication

The Wicket Web Application class is a spring bean triggering the spring boot configuration and start up by using the @EnableAutoConfiguration annotation and providing the main class.

WebInitializer

This class replaces the web.xml by using spring boot's ServletContextInitializer that is found and executed automatically on startup.

It's code is equivalent to the following web.xml part:

<filter>
  <filter-name>wicket-filter</filter-name>
    <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
    <init-param>
        <param-name>applicationFactoryClassName</param-name>
        <param-value>org.apache.wicket.spring.SpringWebApplicationFactory</param-value>
    </init-param>
    <init-param>
        <param-name>applicationBean</param-name>
        <param-value>wicketWebApplication</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>wicket-filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

WarInitializer

This class is used when being deployed on an application server. In this scontext it has the functionality of the Application's main method.

Running / Deployment

Building the project provides two war archives. One is a fully featured spring boot runnable war, the other having the suffix original is a standard war archive ans can be deployed directly on an application server.
