Wicket + Spring Boot + .war file deployment - wicket

Question

Building on the example here: https://github.com/Pentadrago/spring-boot-example-wicket
And taking into account the jar-to-war guide here: https://spring.io/guides/gs/convert-jar-to-war/
I'd like to convert my existing Wicket + Spring (using data-jpa and security) to Spring Boot. It's been fairly easy to get the fat-jar setup to work, but it has so far proved impossible for me to convert this setup into a .war file to deploy in Tomcat.
The issue stems from the conflicting instructions to:
on the one hand extends org.springframework.boot.context.web.SpringBootServletInitializer from a non-#Configuration class for the jar-to-war conversion guide,
while on the other implements org.springframework.boot.context.embedded.ServletContextInitializer for a #Configuration marked class for the fat-jar Wicket example.
I've not been able to align the two such that I get a working application both when debugging with the embedded container, and when deployed as .war in Tomcat.
Can anyone tell me how I can setup a spring-boot enabled wicket application that I can deploy as a .war file?

Answer 1

What I did and got the application to work was the following:
I checked out the example project https://github.com/Pentadrago/spring-boot-example-wicket that you posted.
Then following the code on the https://spring.io/guides/gs/convert-jar-to-war/ guide all I did was to make the following changes:
Change build.gradle to:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.0.2.RELEASE")
}
}
apply plugin: 'java'
apply plugin: 'spring-boot'
apply plugin: 'war'
jar {
version = '0.0.1'
}
repositories {
mavenCentral()
}
configurations {
providedRuntime
}
dependencies {
compile(
"org.springframework.boot:spring-boot-starter",
"org.springframework.boot:spring-boot-starter-logging",
"org.springframework:spring-web:4.0.3.RELEASE",
"org.apache.wicket:wicket-spring:6.15.0",
)
testCompile(
"org.springframework.boot:spring-boot-starter-test",
)
providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
}
Add the following class:
HelloWebXml.java
package spring.boot.example.wicket;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
public class HelloWebXml extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(WicketWebApplication.class);
}
}
Those where the only changes I made and deployed to Tomcat 7 without any problems.
Here is the excerpt from the log that shows that wicked got started
2014-08-27 20:57:41.396 INFO 2708 --- [on(3)-127.0.0.1] org.apache.wicket.Application : [wicket-filter] init: Wicket core library initializer
I am not sure what your source of confusion is but you have to understand that SpringBootServletInitializer and ServletContextInitializer serve different purposes.
