java - 类型 'com/fasterxml/jackson/datatype/jdk8/Jdk8Module'(当前帧，堆栈 [2])不可分配给 'com/fasterxml/jackson/databind/Module'

Question

我将 jackson 库从 2.5.4 升级到 2.10.1，如下所示，我收到以下错误:

"WFLYCTL0080: Failed services" => {
        "jboss.deployment.subunit.\"m2m-rt.ear\".\"app.jar\".POST_MODULE" => "org.jboss.msc.service.StartException in service jboss.deployment.subunit.\"app.ear\".\"app.jar\".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of subdeployment \"app.jar\" of deployment \"app.ear\"
    Caused by: java.lang.RuntimeException: WFLYSRV0177: Error getting reflective information for class Class with ClassLoader ModuleClassLoader for Module \"deployment.app.jar:main\" from Service Module Loader
    Caused by: java.lang.VerifyError: Bad type on operand stack
Exception Details:

  Reason:
    Type 'com/fasterxml/jackson/datatype/jdk8/Jdk8Module' (current frame, stack[2]) is not assignable to 'com/fasterxml/jackson/databind/Module'

通过我自己的研究，我发现在我的 jboss-deployment-structure.xml 中排除 jackson 库应该相当简单:

<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <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>
        <dependencies>
            <module name="org.picketbox"/>
            <module name="org.wildfly.clustering.singleton"/>
            <module name="org.jboss.ws.cxf.jbossws-cxf-client" services="import"/>
            <module name="org.apache.cxf.impl" export="true">
                <imports>
                    <include path="META-INF" />
                    <include path="META-INF/cxf" />
                    <include path="META-INF/services" />
                </imports>
            </module>
        </dependencies>
    </deployment>
    <sub-deployment name="other.jar">
        <dependencies>
            <module name="org.infinispan" slot="5.2"/>
        </dependencies>
    </sub-deployment>
</jboss-deployment-structure>

我还尝试将其包含在我的 jboss 部署结构中，而不是在根级别进行排除:

<sub-deployment name="firstJar.jar">
        <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>
    </sub-deployment>

这是我在我的 gradle 构建脚本中定义我的 jackson 库的方式。这些库是一个 jar 的一部分，它与其他几个 jar 一起部署，并引发了一场 war 。其他四个 jar 模块依赖于包含 jackson 库的 jar

我的第一个 jar 的一部分:

compile 'com.fasterxml.jackson.core:jackson-core:2.10.1'
compile 'com.fasterxml.jackson.datatype:jackson-datatype-jdk8:2.10.1'
compile 'com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.10.1'
compile 'com.fasterxml.jackson.module:jackson-module-parameter-names:2.10.1'

另一个依赖于上述 jar 的 gradle 构建脚本:

dependencies {
   compile project(':components:firstJar')
}

使用 JBoss EAP 7.0.5

当我运行 gradle 依赖项扫描时，我注意到的一件事是使用 2.5.4 版本的 jackson 库，我的扫描看起来像这样:

    +--- com.fasterxml.jackson.core:jackson-core:2.5.4
|    +--- com.fasterxml.jackson.datatype:jackson-datatype-jdk8:2.5.4
|    |    +--- com.fasterxml.jackson.core:jackson-core:2.5.4
|    |    \--- com.fasterxml.jackson.core:jackson-databind:2.5.4
|    |         +--- com.fasterxml.jackson.core:jackson-annotations:2.5.0
|    |         \--- com.fasterxml.jackson.core:jackson-core:2.5.4
|    +--- com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.5.4
|    |    +--- com.fasterxml.jackson.core:jackson-core:2.5.4
|    |    \--- com.fasterxml.jackson.core:jackson-databind:2.5.4 (*)
|    \--- com.fasterxml.jackson.module:jackson-module-parameter-names:2.5.4
|         +--- com.fasterxml.jackson.core:jackson-core:2.5.4
|         \--- com.fasterxml.jackson.core:jackson-databind:2.5.4 (*)

当我为 2.10.1 运行它时，它看起来像这样:

|    +--- com.fasterxml.jackson.core:jackson-core:2.5.4 -> 2.10.1
|    +--- com.fasterxml.jackson.datatype:jackson-datatype-jdk8:2.10.1
|    |    +--- com.fasterxml.jackson.core:jackson-core:2.10.1
|    |    \--- com.fasterxml.jackson.core:jackson-databind:2.10.1
|    |         +--- com.fasterxml.jackson.core:jackson-annotations:2.10.1
|    |         \--- com.fasterxml.jackson.core:jackson-core:2.10.1
|    +--- com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.10.1
|    |    +--- com.fasterxml.jackson.core:jackson-annotations:2.10.1
|    |    +--- com.fasterxml.jackson.core:jackson-core:2.10.1
|    |    \--- com.fasterxml.jackson.core:jackson-databind:2.10.1 (*)
|    \--- com.fasterxml.jackson.module:jackson-module-parameter-names:2.10.1
|         +--- com.fasterxml.jackson.core:jackson-core:2.10.1
|         \--- com.fasterxml.jackson.core:jackson-databind:2.10.1 (*)

我注意到有一个额外的 jackson-annotations 2.10.1 的依赖项。所以我尝试添加 exclude group: 'com.fasterxml.jackson.core', module: 'jackson-annotations'对于 jackson-datatype-jsr310我的 gradle 脚本中的库，它确实将其从依赖项扫描中删除。但我仍然有同样的错误。我也想知道为什么在 2.10.1 的依赖项扫描的第一行中，它说 2.5.4 -> 2.10.1 .

Answer 1

我最终需要排除 jackson和 resteasy多个模块 (jar) 中的库以及我的 jboss-deployment-structure.xml 中的根级别的库.我指定排除库的模块使用导入库的模块(即在我的问题中我声明 A gradle build script of another jar that depends on the one above: 的位置)。

<?xml version="1.0"?>

            <module name="org.jboss.resteasy.resteasy-jackson-provider" />
        </exclusions>
    </sub-deployment>
</jboss-deployment-structure>

我不明白的一件事是为什么我不需要为使用导入库的模块的其他 jar 排除库。
因此，我对其他有此问题的人的建议是尝试使用您从哪些 jar 中排除库以使其正常工作。
