hibernate - 将Hibernate应用程序部署到Wildfly 10-org.dom4j.DocumentFactory ClassCastException

Question

更新:oxt_rstrong现在，我实际上知道了问题所在，可以开始解决它了。

我目前正在评估WildFly 10中Hibernate支持的JPA。但是，在尝试部署我的测试 war (由gradle构建)时，会产生看似无关的错误。以下是控制台日志中的行:

11:11:06,200 ERROR [org.jboss.as.controller.management-operation] (management task-8) WFLYCTL0013: Operation ("add") failed - address: ([("deployment" => "TestWar.war")]) - failure description: {"WFLYCTL0080: Failed services" => {"jboss.persistenceunit.\"TestWar.war#com.myapp.testwar.jpa\"" => "org.jboss.msc.service.StartException in service jboss.persistenceunit.\"TestWar.war#com.myapp.testwar.jpa\": java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory

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

从我的org.hibernate.MappingException:

group 'com.myapp'
name 'TestWar'
version '0.0.0-dev'

apply plugin: 'java'
apply plugin: 'war'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

configurations {
    provided
}

sourceSets {
    main {
        compileClasspath += configurations.provided
    }
}

dependencies {
    provided group: 'dom4j', name: 'dom4j', version: '1.6.1'
    provided group: 'javax.enterprise', name: 'cdi-api', version: '1.2'
    provided group: 'javax.inject', name: 'javax.inject', version: '1'
    provided group: 'org.hibernate', name: 'hibernate-core', version: '5.0.7.Final'
    provided group: 'org.hibernate', name: 'hibernate-entitymanager', version: '5.0.7.Final'
    provided group: 'org.hibernate', name: 'hibernate-envers', version: '5.0.7.Final'
    provided group: 'org.hibernate', name: 'hibernate-java8', version: '5.0.7.Final'
    provided group: 'org.hibernate.javax.persistence', name: 'hibernate-jpa-2.1-api', version: '1.0.0.Final'
    provided group: 'org.jboss.spec.javax.annotation', name: 'jboss-annotations-api_1.2_spec', version: '1.0.0.Final'
    provided group: 'org.jboss.spec.javax.ejb', name: 'jboss-ejb-api_3.2_spec', version: '1.0.0.Final'
    provided group: 'org.jboss.spec.javax.sql', name: 'jboss-javax-sql-api_7.0_spec', version: '2.0.0.Final'
    provided group: 'org.jboss.spec.javax.ws.rs', name: 'jboss-jaxrs-api_2.0_spec', version: '1.0.0.Final'
    provided group: 'org.postgresql', name: 'postgresql', version: '9.4.1209'
}

我从类似的帖子中尝试了以下解决方案:

Making all dependencies provided

Adding build.gradle to my dependencies(似乎不必要，因为dom4j将其显示为多个休眠库的子代)

Ensure there is only one gradle dependencies jar in the classpath(我的 war 中根本没有图书馆)

以及其他来源的这些:

Adding dom4j to MANIFEST.MF

Adding Dependencies: org.dom4j with the following content:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
  <deployment>
    <dependencies>
      <module name="org.dom4j"/>
    </dependencies>
    <local-last value="true"/>
  </deployment>
</jboss-deployment-structure>

有人有其他建议吗，还是我做过一些愚蠢的事情？

编辑:显然，此错误可能是由任何数据源配置问题引起的(请参阅here)。作为引用，通过管理控制台对我的数据源的连接测试成功，并且据我所知所有连接详细信息都是正确的。

之所以会发生此错误，是因为您在依赖项列表中包含了EntityManager。删除它。正常操作不需要它。
