从JBoss 7 EAP中排除提供的杰克逊版本 [英] Exclude provided jackson version from JBoss 7 EAP

问题描述

随着JBoss 7 EAP的发布，我正在尝试使用较新版本的Jackson.为了解决我的问题，我创建了一个 jboss-deployment-structure.xml 文件，该文件包含在我的战争部署中.

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <deployment>
        <exclusions>
            <!--<module name="com.fasterxml.jackson.core.jackson-core" slot="main" />-->
            <!--<module name="com.fasterxml.jackson.core.jackson-annotations" slot="main" />-->
            <module name="com.fasterxml.jackson.core.jackson-databind" slot="main" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

但是似乎JBoss使用交付的模块而不是提供的依赖项.

ModuleClassLoader的模块 本地模块中的"com.fasterxml.jackson.core.jackson-databind:main" 加载程序@ 134593bf(查找器:本地模块查找器@ 4bb4de6a(根: ... \ jboss-eap-7.0 \ modules，... \ jboss-eap-7.0 \ modules \ system \ layers \ base))

我发现了一个类似的问题 JBoss 7 Classloader-排除模块实现，但是对我没有帮助. /p>

我想念什么?

解决方案

我遇到了与Jackson完全相同的问题，并使用jboss-deployment-structure.xml使其在我的EAP 7中正常工作:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="com.fasterxml.jackson.core.jackson-core" />
            <module name="com.fasterxml.jackson.core.jackson-annotations" />
            <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" />
            <module name="org.jboss.resteasy.resteasy-jackson-provider" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

似乎只要任何 other 模块都将jackson列出为它们在各自module.xml中的依赖关系，就不会被排除，并且EAP甚至都不会抛出警告.

编辑2018-02-19::从EAP 7.0.0升级到7.1.0时，由于更新了Jackson罐子，事情再次崩溃.

这是stacktrace的关键部分:

Caused by: javax.ejb.EJBException: WFLYEJB0442: Unexpected Error
    at org.jboss.as.ejb3.tx.CMTTxInterceptor.handleExceptionInOurTx(CMTTxInterceptor.java:185)
[...]
    at org.jboss.as.ee.component.BasicComponent.constructComponentInstance(BasicComponent.java:161) [wildfly-ee-7.1.0.GA-redhat-11.jar:7.1.0.GA-redhat-11]
    ... 11 more
Caused by: java.lang.VerifyError: Bad type on operand stack
Exception Details:
  Location:

  Reason:
    Type 'com/fasterxml/jackson/datatype/jdk8/Jdk8Module' (current frame, stack[1]) is not assignable to 'com/fasterxml/jackson/databind/Module'

所以我们也排除了这些:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="com.fasterxml.jackson.core.jackson-core" />
            <module name="com.fasterxml.jackson.core.jackson-annotations" />
            <module name="com.fasterxml.jackson.core.jackson-databind" />
            <module name="com.fasterxml.jackson.datatype.jackson-datatype-jdk8" />
            <module name="com.fasterxml.jackson.datatype.jackson-datatype-jsr310" />
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson-provider" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

I am trying to use a newer version of Jackson as JBoss 7 EAP delivers. To solve my issue I have created a jboss-deployment-structure.xml file which is contained in my war deployment.

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <deployment>
        <exclusions>
            <!--<module name="com.fasterxml.jackson.core.jackson-core" slot="main" />-->
            <!--<module name="com.fasterxml.jackson.core.jackson-annotations" slot="main" />-->
            <module name="com.fasterxml.jackson.core.jackson-databind" slot="main" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

But it seems that JBoss uses the delivered module instead of the provided dependency.

ModuleClassLoader for Module "com.fasterxml.jackson.core.jackson-databind:main" from local module loader @134593bf (finder: local module finder @4bb4de6a (roots: ...\jboss-eap-7.0\modules,...\jboss-eap-7.0\modules\system\layers\base))

I have found a similar question JBoss 7 Classloader -- Exclude Module Implementation but it didn't help me.

What did I miss?

解决方案

I ran into the exact same problem with Jackson, and I got it to work in my EAP 7 using this jboss-deployment-structure.xml :

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="com.fasterxml.jackson.core.jackson-core" />
            <module name="com.fasterxml.jackson.core.jackson-annotations" />
            <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" />
            <module name="org.jboss.resteasy.resteasy-jackson-provider" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

It appears like as long as any other modules list jackson as their dependency in their respective module.xml, it just simply doesn't get excluded, and EAP can't be arsed to even throw a warning about it.

Edit 2018-02-19: When upgrading from EAP 7.0.0 to 7.1.0, things broke again, owing to updated Jackson jars.

This is the crucial part of the stacktrace:

Caused by: javax.ejb.EJBException: WFLYEJB0442: Unexpected Error
    at org.jboss.as.ejb3.tx.CMTTxInterceptor.handleExceptionInOurTx(CMTTxInterceptor.java:185)
[...]
    at org.jboss.as.ee.component.BasicComponent.constructComponentInstance(BasicComponent.java:161) [wildfly-ee-7.1.0.GA-redhat-11.jar:7.1.0.GA-redhat-11]
    ... 11 more
Caused by: java.lang.VerifyError: Bad type on operand stack
Exception Details:
  Location:
    [...]()Lcom/fasterxml/jackson/databind/ObjectMapper; @89: invokevirtual
  Reason:
    Type 'com/fasterxml/jackson/datatype/jdk8/Jdk8Module' (current frame, stack[1]) is not assignable to 'com/fasterxml/jackson/databind/Module'

So we exclude those as well:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="com.fasterxml.jackson.core.jackson-core" />
            <module name="com.fasterxml.jackson.core.jackson-annotations" />
            <module name="com.fasterxml.jackson.core.jackson-databind" />
            <module name="com.fasterxml.jackson.datatype.jackson-datatype-jdk8" />
            <module name="com.fasterxml.jackson.datatype.jackson-datatype-jsr310" />
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson-provider" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>
