jboss - Wildfly 和 jackson : LinkageError

Question

我正在尝试将 jboss wildfly 8 配置为将 Jackson 用于 JSON。所以我加了

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson-provider</artifactId>
    <version>3.0.6.Final</version>
    <type>jar</type>
</dependency>

到我的耳朵项目。但是在部署时出现以下错误:

Caused by: java.lang.LinkageError: loader constraint violation: when resolving overridden method "org.jboss.resteasy.plugins.providers.jackson.ResteasyJacksonProvider$Proxy$_$$WeldClientProxy.disable(Lorg/codehaus/jackson/map/Des erializationConfig$Feature;Z)Lorg/codehaus/jackson/jaxrs/JacksonJsonProvider;" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, org/jboss/resteasy/plugins/providers/jackson/ResteasyJacksonPr ovider$Proxy$$$WeldClientProxy, and its superclass loader (instance of org/jboss/modules/ModuleClassLoader), have different Class objects for the type sy.plugins.providers.jackson.ResteasyJacksonProvider$Proxy$$$_WeldClientProx y.disable(Lorg/codehaus/jackson/map/DeserializationConfig$Feature;Z)Lorg/codehaus/jackson/jaxrs/JacksonJsonProvider; used in the signature

3.0.6 版本与 Wildfly 不兼容吗？我怎么知道哪个版本有效？我也尝试了 2.3.7 和 1.1，但总是出现同样的错误。

编辑:

我有一个带有 pojos 的 ejb 模块。这里我有依赖:

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.2.3</version>
        <scope>provided</scope>
        <type>jar</type>
    </dependency>

所以这对我来说很像 jackson 2。

在我耳边，我有以下依赖:

<dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson-provider</artifactId>
        <version>3.0.6.Final</version>
        <type>jar</type>
        <scope>provided</scope>
</dependency>

我现在需要 resteasy-jackson2-provider 吗？我现在需要 jboss-deployment-structure.xml 吗？

Answer 1

WildFly 8 已经包含了 Jackson。用 <scope>provided</scope> 标记依赖关系.然后您需要添加 jboss-deployment-structure.xml 根据 documentation 将以下内容添加到您的部署中.

<jboss-deployment-structure>
    <deployment>
        <exclusions>
           <module name="org.jboss.resteasy.resteasy-jackson-provider"/>
        </exclusions>
        <dependencies>
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>
