我目前正在开发一个依赖JavaEE7的原型。Maven用于依赖关系管理，插件Maven ear插件用于最终ear构建。后者随后部署在wildfly 10.0应用服务器上

项目结构如下（简化）：

  • 控制器api
  • 控制器植入
  • 模型api
  • 模型impl
  • 系统父级（maven父级包）
  • 系统ear（生成ear）
  • 查看webapp
EAR由两个ejb3模块“ControllerImpl”和“ModelImpl”以及web应用程序“ViewWebApp”组成。maven ear插件的配置如下：

<plugin>  
    <groupId>org.apache.maven.plugins</groupId>  
    <artifactId>maven-ear-plugin</artifactId>  
    <configuration>  
        <defaultLibBundleDir>lib</defaultLibBundleDir>  
        <generatedDescriptorLocation>META-INF</generatedDescriptorLocation>  
        <modules>  
            <ejbModule>  
                <groupId>com.domain.abc</groupId>  
                <artifactId>model-impl</artifactId>  
            </ejbModule>  
            <ejbModule>  
                <groupId>com.domain.abc</groupId>  
                <artifactId>controler-impl</artifactId>  
            </ejbModule>  
             <webModule>  
                <groupId>com.domain.abc</groupId>  
                <artifactId>view-webapp</artifactId>  
                <contextRoot>/myapp</contextRoot>  
            </webModule>  
        </modules>  
    </configuration>  
</plugin>
似乎提供的的问题结果取决于您对控制器impl模块的依赖性

按照提供的依赖关系，您没有将其绑定到JAR的类路径，即使它被提取并放入EAR/lib文件夹中

您需要从EAR pom.xml文件中删除依赖项，并从controler impl模块的反射依赖项中删除提供的关键字

为此，需要Maven将依赖项绑定到JAR的类路径，并通过传递性，将其放在EAR/lib文件夹中。

您可以发布application.xml和stacktrace吗？您介意使用使用您的reflections-0.9.10.jar的模块的pom.xml文件更新您的问题吗？问题似乎可能是由Controller impl模块的reflections依赖项引起的。您是否也在EAR中声明了反射依赖项？问题可能是您试图从彼此访问EJB JAR。我认为这在默认情况下是不可能的。配置您的standalone.xml:false根据以下指南：@aribeiro反射依赖项在EAR中定义，库成功包含在EAR中
