如何在JAX-RS应用程序中更改Jackson版本（WebSphere Liberty）(How to change Jackson version in JAX-RS app (WebSphere Liberty))

 我将一个JAX-RS应用程序从WebSphere 8.0迁移到WebSphere Liberty 8.5.5。 
 
 在WebSphere 8.0中，Jackson由WebSphere提供。 我可以在jackson-core-asl-1.9.12.jar找到jackson-core-asl-1.9.12.jar ， jackson-jaxrs-1.9.12.jar ， jackson-mapper-asl-1.9.12.jar和jackson-xc-1.9.12.jar文件AppServer\plugins\目录。 
 
 在新的应用程序服务器（WebSphere Liberty）中，出现以下异常： org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "myPropertyName" 。 我认为发生这种异常是因为序列化类中的注释@JsonIgnoreProperties(ignoreUnknown = true)不起作用。 我的猜测是，它发生是因为WebSphere Liberty 8.5.5提供了一个老版本的Jackson。 
 
 我试图用我的应用程序部署我需要的Jackson版本，但它没有帮助（我仍然有例外）。 我如何让WebSphere Liberty使用我需要的Jackson版本？ 

I am migrating a JAX-RS application from WebSphere 8.0 to WebSphere Liberty 8.5.5.
 
In WebSphere 8.0, Jackson was provided by WebSphere. I can find jackson-core-asl-1.9.12.jar, jackson-jaxrs-1.9.12.jar, jackson-mapper-asl-1.9.12.jar and jackson-xc-1.9.12.jar files in the AppServer\plugins\ directory.
 
In the new application server (WebSphere Liberty), I get the following exception: org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "myPropertyName". I think that this exception happens because the annotation @JsonIgnoreProperties(ignoreUnknown = true) on the serialized classes does not work. My guess is that it happens because WebSphere Liberty 8.5.5 provides an older version of Jackson.
 
I tried to deploy the version of Jackson which I need with my application, but it did not help (I still have exceptions). How can I make WebSphere Liberty use the version of Jackson that I need?
