java.lang.ClassNotFoundException: org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

Question

I am using spring-integration in my project. When I deploy my app in the jetty container, I am getting the following exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'integrationRequestMappingHandlerMapping': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'inboundhttpJobRequestGateway': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.integration.http.inbound.HttpRequestHandlingMessagingGateway]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/http/converter/json/MappingJackson2HttpMessageConverter

I have both the jars jackson-core-asl-1.8.3 and jackson-core-2.3.1 in the class path. Still I am getting the error. How to resolve the problem?

Normally, the class MappingJackson2HttpMessageConverter exists in spring-web.jar (or spring-web-x.y.z-RELEASE.jar), you should add it to your classpath, or if using maven add following dependency :

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>x.y.z.RELEASE</version>
</dependency>

Edit per Artem Bilan comment :

Normally, if you use maven, it should be present as a dependency of spring-integration-http, provided you have this one.

`spring-web` is a required transitive dependency of `spring-integration-http`. And if you use correctly dependency managemet tool it should be there anyway. – Artem Bilan Oct 01 '14 at 13:06
@ArtemBilan : you are right, but the error message suggests it is not there ;-) But I change last part of my answer that is irrelevant. – Serge Ballesta Oct 01 '14 at 13:14
Thanks, it saved my time – Neo Ravi Apr 07 '18 at 15:25

I had this weird error, too. I did a search in my jars in the web server's (tomcat) webapps/myapp/WEB-INF/lib and the class was there -- and only once.

It went away when I looked at another project at my job and used the same jackson jars.

Originally, I had the following:

jackson-core-2.4.3.jar
jackson-databind-2.4.3.jar

I removed these and added the following (packaged into my WEB-INF/lib):

jackson-mapper-asl-1.9.13.jar
jackson-datatype-jsr310-2.5.0.jar
jackson-datatype-joda-2.5.0.jar
jackson-databind-2.5.0.jar
jackson-core-2.5.0.jar
jackson-annotations-2.5.0.jar

I'm running this on Tomcat 7 on windows; using Java 1.6 (for compiling and runtime in Tomcat)

servlet.xml:

<beans:bean id="jacksonMessageConverter"  
    class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" >
</beans:bean>

    <beans:bean  class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <beans:property name="messageConverters">
            <beans:list>
                <beans:ref bean="jacksonMessageConverter" />
            </beans:list>
        </beans:property>
    </beans:bean>

In case it helps, I run the following shell from cygwin for searching for jats

JAR="C:/java/Java/jdk1.7.0_71/bin/jar.exe"
srchdir="c:/appservers/apache-tomcat-7.0.57/webapps/my-web/WEB-INF/lib"

echo "SEARCH FOLDER: $srchdir"
find  $srchdir -print | grep '\.jar$' | while read f
do
    $JAR tf $f | grep 'MappingJackson2HttpMessageConverter\.class' >/dev/null 2>&1
    [ $? -eq 0 ] && echo "==> $f" && $JAR tf $f | grep MappingJackson2HttpMessageConverter\.class
done

It's interesting what is com.dsths.common.container.ContainerClassLoader...

Looks like spring-integration-http is loaded by this ClassLoader, but MappingJackson2HttpMessageConverter and all others spring-web classes with another ClassLoader.

Would be great, if you place all spring jars within the same class loader.

The app is not able to find MappingJackson2HttpMessageConverter in the class path. The problem is one class loader is picking one version and another class loader is picking another version.

I have `jackson-databind-2.3.1.jar` in the class path.Do I need to have `jackson-core-asl-2` in the class path too? – Ashok.N Oct 01 '14 at 12:28
Forget that. I've changed my answer. Sorry: hadn't looked to your StackTrace properly – Artem Bilan Oct 01 '14 at 12:30
Thanks for quick response. I am using custom jetty container. `com.dsths.common.container.ContainerClassLoader` is part of the custom container. is having conflicting versions of jars lead to the above problem? – Ashok.N Oct 01 '14 at 12:38
No-no. There is no version conflicts. All spring jar should be at the same place, because, as we see, different classloader don't see all classes – Artem Bilan Oct 01 '14 at 12:44
Artem Bilan, how to place all spring jars within the sama class loader? Could you please elaborate more? Actually, my container has a `lib/container` folder where all jars are placed. The class loader will load all those jars.Still wondering how two class loaders are involved in this?because only one class loader should be there I guess. – Ashok.N Oct 01 '14 at 12:59
Actually they should be placed in the `WEB-INF/lib`, because you say that you use custom classloader. – Artem Bilan Oct 01 '14 at 13:07
Sorry for my late reply. I was on vacation for all these days.Yes, you are almost correct. The problem here is I have Spring 3.1.1.RELEASE JARS under my WEB-INF/lib, and my container has 3.2.4.RELEASE version. So, due to this conflict, my app is unable to find MappingJackson2HttpMessageConverter. When I upgraded spring jar versions to 3.2.4.RELEASE from 3.1.1.RELEASE, the problem is solved. – Ashok.N Oct 10 '14 at 06:29
Artem Bilan, +1 for your continuous support. – Ashok.N Oct 10 '14 at 06:30

Basically, it's a jar package problem. You can't find this method in the jar package you imported. You should replace it with another jar package
