Wildfly 9 - 如何排除杰克逊 [英] Wildfly 9 - How do I exclude Jackson

问题描述

我遇到了地图中带有空值的杰克逊序列化问题。显然，这是Wildfly 9使用的Jackson版本中的已知错误（

我知道如何让它工作吗？

解决方案

我刚刚遇到了这个问题。

在我的应用程序中升级库之后，我收到了以下错误请求：

 对/ path的异常处理请求：java.lang.NoSuchMethodError：com.fasterxml.jackson.core.JsonParser。 hasToken（Lcom / fasterxml / jackson / core / JsonToken;）
  

这就是我解决的问题它：

我显然不得不排除 jackson-core-2.5.1 那个wildfly-9提供。

我列出了依赖于'jackson-core'的所有模块 / opt / wildfly / module s＃grep -R'jackson-core'

然后我创建了一个 jboss-deployment-structure.xml 在我的 WEB-INF 文件夹中：

  < JBoss的部署-结构> 
< deployment> 
< exclusions> 
< 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> 
  

I'm running into a Jackson serialization issue with null values in maps. Apparently this is a known bug in the Jackson version used by Wildfly 9 (https://issues.jboss.org/browse/WFLY-4906). I'd like to use the current version of Jackson; however, I'm having trouble excluding the version used by Wildfly. I tried excluding the module in jboss-deployment-structure.xml but the exclusion is not working.

Any idea how I can get this to work?

解决方案

I just ran into this issue myself.

After upgrading a library in my application, I received the following error on a request:

Exception handling request to /path: java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonParser.hasToken(Lcom/fasterxml/jackson/core/JsonToken;)

Here is how I solved it:

I obviously had to exclude jackson-core-2.5.1 that wildfly-9 provides.

I listed all modules that depend on 'jackson-core' with /opt/wildfly/modules# grep -R 'jackson-core'

Then I created a jboss-deployment-structure.xml in my WEB-INF folder:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <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>
