Trying to build Spring Boot to deploy in Wildfly

Question

I can create a simple Hello World, but what is interesting is that if I use Spring Boot 1.5.10.RELEASE, or 2.0. I get an exception. 1.2.7 starts fine.

Here is the serve.log from the 2.0.0 run. It seems to start with the failure to inherit from final class? Is there some sort of versions mismatch? Something with the httpPutFormContentFilter class?

Answer 1

This seems to be related to this GitHub issue: https://github.com/spring-projects/spring-boot/issues/9391. Your stack is very similar to the mentioned stack there. It looks like the classloader is failing during Jackson module registration due to a conflict with Wildfly's included (potentially older) version of Jackson.

Do you have jackson-datatype-jdk8 on your classpath? You may need to modify your Wildfly configuration to prevent deploying its own version of jackson as in this Spring Boot example: https://github.com/spring-projects/spring-boot/commit/f8a5e3d0b79e367612bb8396f05120361b81a886. Even if you haven't manually added jackson-datatype-jdk8 to your classpath, these Wildfly exclusions may still be necessary if Spring Boot includes it in one of its packages.

The Wildfly example adds the following file:

<!-- WEB-INF/jboss-deployment-structure.xml -->

<?xml version='1.0' encoding='UTF-8'?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
    <deployment>
        <exclusions>
            <module name="com.fasterxml.jackson.core.jackson-annotations" />
            <module name="com.fasterxml.jackson.core.jackson-core" />
            <module name="com.fasterxml.jackson.core.jackson-databind" />
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

For a complete example of Spring Boot on Wildfly, see the tests in the official Spring Boot GitHub repository here: https://github.com/spring-projects/spring-boot/tree/f47d60e7d47f9c91fc453c9c40248ef1d36acaad/spring-boot-tests/spring-boot-deployment-tests/spring-boot-deployment-test-wildfly
