Deploying Spring Boot WAR on WildFly

Question

I have followed the steps mentioned here Create a Deployable War File Things are working fine when I run (mvn spring-boot:run) and when I package using (mvn clean package) But the created WAR is never deployed to WildFly 8 and I receive the below exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'halObjectMapper' defined in class path resource [org/springframework/data/rest/webmvc/config/RepositoryRestMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.fasterxml.jackson.databind.ObjectMapper]: Factory method 'halObjectMapper' threw exception; nested exception is java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.ser.ContainerSerializer: method <init>(Lcom/fasterxml/jackson/databind/JavaType;)V not found

Any clue about what I'm missing?

Answer 1

Wildfly includes it own version of Jackson that leaks into the class space for your application. These Jackson classes are overwriting those that are packaged in your war. You can avoid this pollution by excluding some modules in a WEB-INF/jboss-deployment-structure.xml file in your war. Its contents should be something like the following:

<?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.datatype.jackson-datatype-jdk8"/>
            <module name="com.fasterxml.jackson.datatype.jackson-datatype-jsr310"/>
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

The above is a slightly modified version of the configuration that's used in Spring Boot's Wildfly deployment test.
