wildfly 10：java.lang.ClassCastException：org.dom4j.DocumentFactory无法强制转换为org.dom4j.DocumentFactory

标签： maven wildfly-10

我有一个maven应用程序，可以在wildfly 8.2中正常工作，但是当它在wildfly 10中使用它时，会发生以下错误：

[2016-02-21 11:22:08,411] Artifact SaramadIssueTracking:war exploded: Error during artifact deployment. See server log for details.
[2016-02-21 11:22:08,411] Artifact SaramadIssueTracking:war exploded: java.lang.Exception: {"WFLYCTL0080: Failed services" =>

    Caused by: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory"}}

我读了this并且没有其他dom4j库。我也读了this并做了，但删除dom4j后，我收到了这个错误：

    [2016-02-21 01:46:38,384] Artifact SaramadIssueTracking:war exploded: Error during artifact deployment. See server log for details.

我刚刚提供了所有hibernate依赖项，并且解决了范围和问题！

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>5.1.0.Final</version>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-validator</artifactId>
            <version>5.2.4.Final</version>
            <scope>provided</scope>
        </dependency>

        <!-- for JPA, use hibernate-entitymanager instead of hibernate-core -->
        <dependency>
            <groupId>org.hibernate</groupId>

答案 1 :(得分：13)

将依赖dom4j添加到pom并提供范围

<dependency>
   <groupId>dom4j</groupId>
   <artifactId>dom4j</artifactId>
   <version>1.6.1</version>
   <scope>provided</scope>
</dependency>

答案 2 :(得分：9)

我最近遇到了与dom4j库和Wildfly 10相同的问题。我找到了this post（用葡萄牙语）并用Wildven下载的dom4j库替换了从Maven Central下载的那个库，这解决了问题

jar位于$JBOSS_HOME/modules/system/layers/base/org/dom4j/main，您只需将其替换为下载的文件，在我的情况下，文件为dom4j-1.6.1.jar。我想如果你改变版本（在这篇文章的时候这是最后一个版本）你也应该修改同一文件夹中的module.xml文件，但我没试过。

以前我也试过h.f的自我答案，但没有解决我的问题。

希望这有助于遇到同样问题的人。最好的问候

答案 3 :(得分：9)

如果您使用hibernate-core作为依赖项，则应确保提供范围。通过将<scope>更改为provided来解决冲突，hibernate工件将dom4j的版本作为依赖项。

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.3.1.Final</version>
        <type>jar</type>
        <scope>provided</scope>
    </dependency>

我希望这能让你微笑:)

答案 4 :(得分：3)

我遇到了同样的问题，但最后我做的是从pom中删除（冗余）Hibernate库。

由于Wildfly已经将Hibernate用作JPA提供程序（https://docs.jboss.org/author/display/WFLY10/JPA+Reference+Guide#JPAReferenceGuide-Introduction），因此您根本不需要提供此类（除非您直接使用Hibernate类）。

所以最小配置工作正常：

<project>
  <dependencies>
    <dependency>
      <groupId>javax</groupId>
      <artifactId>javaee-api</artifactId>
      <version>7.0</version>
      <scope>provided</scope>
    </dependency>
  </dependencies>
</project>

和persistence.xml 

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
         version="2.0">
<persistence-unit name="mysql_hbm" transaction-type="JTA">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>java:/jdbc/MySqlDS</jta-data-source>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
        <property name="hibernate.show_sql" value="true"/>
    </properties>
</persistence-unit>

在Wildfly 10上测试。

答案 5 :(得分：3)

此处的其他建议要么对我不起作用，要么不适用于我的项目。我在this blog找到了一个可能的解决方案。基本上它会将Dependencies: org.dom4j export添加到{your war}/META-INF/MANIFEST.MF。我正在运行Wildfly 10并在我的耳朵和ejb项目中这样做似乎已经有效。

答案 6 :(得分：2)

从hibernate中排除依赖dom4j。

检查结果acme.war / WEB-INF / lib没有dom ***。jar 

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.3.8.Final</version>
    <exclusions>
        <exclusion>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>

            <artifactId>dom4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>

答案 7 :(得分：2)

在我的ear文件的META-INF下的'jboss-deployment-structure.xml'中添加以下解决了这个问题并在weblogic＆amp; wildfly 

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.dom4j" export="true"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

答案 8 :(得分：1)

有同样的问题，但我使用hibernate5官方快速启动解决了它https://github.com/wildfly/quickstart/tree/11.x/hibernate5

尝试hibernate5快速启动，它应该可以工作。

看一下pom.xml，它包含

<!-- Import the JPA API, we use provided scope as the API is included in WildFly -->
    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.1-api</artifactId>
        <scope>provided</scope>
    </dependency>

    <!-- Bean Validation Implementation -->
    <!-- Provides portable constraints such as @Email -->
    <!-- Hibernate Validator is shipped in WildFly -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <scope>provided</scope>
        <exclusions>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <!--Import dependencies to hibernate packages(eg. hibernate-core)
        depending on features you want to use like Hibernate Session used in the
        quickstart -->
    <!--please note that scope is provided as these jars are shipped
        with as7 -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <scope>provided</scope>
    </dependency>

包括它，它会起作用。我不得不取消部署我的应用程序并重新启动wildfly。

如果您需要使用另一个Hibernate版本而不是Wildfly中提供的版本，请按照官方procedure to update the Hibernate version in Wildly，部分替换当前使用较新版本的Hibernate 5.x jar 。

答案 9 :(得分：0)

我正在使用Eclipse Neon.3（4.6.3）和Wildfly 10.1.0。

对我有用的是从standalone.xml目录中恢复较旧的<wildfly>\standalone\configuration\standalone_xml_history文件。我关闭服务器，然后用旧备份替换当前配置文件。

我不知道配置中发生了什么变化（我没有手动改变它），但似乎错误信息也可能是由standalone.xml中的变化引起的。

如果其他解决方案都不适合您，也许这些信息会有所帮助。

答案 10 :(得分：0)

您的EAR可能包含重复的spring jpa配置文件，请检查并删除重复的文件

答案 11 :(得分：0)

有两种方法。

1 您在webapp文件夹中创建一个META-INF文件夹。稍后在META-INF文件夹中创建jboss-deployment-structure.xml。

  

jboss-deployment-structure.xml 

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.dom4j"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

或

2 如果您在pom xml中添加了hibernate-core，则可以对其进行编辑。

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.3.1.Final</version>
        <type>jar</type>
        <scope>provided</scope>
    </dependency>

答案 12 :(得分：0)

就我而言，这有助于从/ data和/ tmp中删除文件

答案 13 :(得分：-1)

我遇到了同样的问题。我按照这个指示操作了。 http://blog.triona.de/development/java/org-dom4j-documentfactory-classcastexception-on-hudson.html

根据这篇文章https://issues.jboss.org/browse/WFLY-5549，我们需要创建一个名为boss-deployment-structure.xml的文件，内容为

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.dom4j"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

然后将其放入../wildfly/modules/system/layers/base/org/jboss/as/product/wildfly-full/dir/META-INF

我希望这会有所帮助。
