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

问题描述

我遇到了一个 Jackson 序列化问题，地图中有空值.显然，这是 Wildfly 9 (

知道如何让它发挥作用吗?

解决方案

我自己刚刚遇到了这个问题.

在我的应用程序中升级库后，我收到了以下请求错误:

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

我是这样解决的:

我显然不得不排除wildfly-9提供的jackson-core-2.5.1.

我用 /opt/wildfly/modules# grep -R 'jackson-core'

列出了所有依赖于 'jackson-core' 的模块

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

<部署><排除事项><模块名称="com.fasterxml.jackson.core.jackson-core"/><模块名称="com.fasterxml.jackson.core.jackson-databind"/><模块名称="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider"/><模块名称="org.jboss.resteasy.resteasy-jackson2-provider"/></排除项></部署></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>
