How to externalise .properties files when deploying a Spring Boot WAR in Wildfly Server? - spring

Question

I am developing a web application using Spring Boot, and want to generate war instead of jar.
It works fine using the conversion from jar to war described here : http://spring.io/guides/gs/convert-jar-to-war/
But I want to externalize the application.properties from the war, because I want to be able to modify it without opening the war archive.
I already defined the spring-boot-maven plugin.
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<classifier>spring-boot</classifier>
<mainClass>
com.application.Application
</mainClass>
</configuration>
</execution>
</executions>
</plugin>
I think I need to add Dependency: config to my manifest file.
So, I've done it like that :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<archive>
<manifestEntries>
<Dependencies>config</Dependencies>
</manifestEntries>
</archive>
</configuration>
</plugin>
But when I launch the Application.war on Wildfly 8.4, I've got this
{"JBAS014671: Failed services" => {"jboss.module.service.\"deployment.Application.war\".main" => "org.jboss.msc.service.StartException in service jboss.module.service.\"deployment.screening.war\".main: JBAS018759: Failed to load module: deployment.Application.war:main
Caused by: org.jboss.modules.ModuleNotFoundException: config:main"}}
I would like that my application start with my custom MANIFEST.MF (with Dependency: config) so that I can externalize my application.properties file.
Thank you.

The problem was on the server side !
When you specify a package, you need to add a module.xml file with a Wildfly server.
So in modules/config/main/, I've added my application.properties and a module.xml file that contains :
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="config">
<resources>
<resource-root path="."/>
</resources>
</module>
Thank you for your response #NielsNet.
