wildfly 10: java.lang.ClassCastException: org.dom4j.DocumentFactory 无法转换为 org.dom4j.DocumentFactory

wildfly 10: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory

我有一个在 wildfly 8.2 中运行良好的 Maven 应用程序,但是当我在 wildfly 10 中部署它时,出现了这个错误:

[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"}}

我阅读 this and there was no other dom4j library. I also read this 并做到了,但是在删除 dom4j 之后,我得到了这个错误:

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

将依赖项 dom4j 添加到具有提供范围的 pom

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

我刚刚制作了所有提供范围和问题的休眠依赖项!

        <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>
            <artifactId>hibernate-entitymanager</artifactId>
            <version>5.1.0.Final</version>
            <scope>provided</scope>
        </dependency>

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

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

由于 Wildfly 已经使用 Hibernate 作为 JPA 提供程序 (https://docs.jboss.org/author/display/WFLY10/JPA+Reference+Guide#JPAReferenceGuide-Introduction),您根本不需要提供这样的 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。

我最近遇到了与 dom4j 库和 Wildfly 10 相同的问题。我找到 this post(葡萄牙语)并将 Wildfly 附带的 dom4j 库替换为从 Maven Central 下载的库,然后解决了问题。

jar 位于 $JBOSS_HOME/modules/system/layers/base/org/dom4j/main,您只需用下载的文件替换它,在我的例子中,文件是 dom4j-1.6.1.jar。我想如果你改变版本(在这个时候 post 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,但我没有试过。

之前我也尝试过h.f的自答,但没有解决我的问题。

希望这对遇到同样问题的人有所帮助。最好的问候

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 中找到了可能的解决方案。基本上它说要将 Dependencies: org.dom4j export 添加到 {your war}/META-INF/MANIFEST.MF。我是 运行 Wildfly 10,在我的耳朵和 ejb 项目中这样做似乎都有效。

如果您使用 hibernate-core 作为依赖项,您应该确保提供范围。 hibernate 工件有一个 dom4j 版本作为依赖项,通过将 <scope> 更改为 provided 来解决冲突。

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

我希望这会让你微笑 :)

从休眠依赖项中排除依赖项 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>
    <version>4.3.8.Final</version>
    <exclusions>
        <exclusion>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>

有同样的问题,但我使用这里提供的 hibernate5 官方快速入门解决了它 https://github.com/wildfly/quickstart/tree/11.x/hibernate5

试试 hibernate5 快速启动,应该可以。

看看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,它将起作用。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 Wildfly 中提供的版本以外的其他 Hibernate 版本,请按照官方 procedure to update the Hibernate version in Wildly部分用更新版本替换当前的 Hibernate 5.x jar.

在我的 ear 文件 META-INF 下的 'jboss-deployment-structure.xml' 中添加以下内容解决了问题并在 weblogic 和 wildfly 中工作

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

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

对我有用的是 <wildfly>\standalone\configuration\standalone_xml_history 目录中恢复一个较旧的 standalone.xml 文件。我关闭了服务器,然后用旧的备份替换了当前的配置文件。

我不知道配置中发生了什么变化(我没有手动更改它),但似乎错误消息也可能是由 standalone.xml 中的更改引起的。

如果 none 其他解决方案适合您,此信息可能会有所帮助。

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

我遇到了同样的问题。我按照此说明进行操作并且有效。 http://blog.triona.de/development/java/org-dom4j-documentfactory-classcastexception-on-hudson.html

根据这个 post 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>

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

希望对您有所帮助。

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>

2 如果你在 pom 中添加了 hibernate-core xml 然后你编辑它。

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

在我的案例中,帮助删除了 /data 和 /tmp 中的文件
