【中文标题】JBoss EAP 7 exclude webservices 子系统给出 NoClassDefFoundError: Failed to link EndpointDefinitionParser$SpringEndpointImpl【英文标题】：JBoss EAP 7 exclude webservices subsystem gives NoClassDefFoundError: Failed to link EndpointDefinitionParser$SpringEndpointImpl 【发布时间】：2017-10-17 10:56:43 【问题描述】：在 Jboss EAP7 中，我在 pom.xml 中添加了 cxf maven 依赖项，并在 jboss-deployment-structure.xml 中排除了 webservices 子系统，因为我想使用我自己在 pom.xml 中定义的 cxf 版本。但是在服务器启动期间出现以下异常-

【问题讨论】：
【参考方案1】：您的应用程序正在使用 spring，因此，您确定您已经在 EAP 7 中安装了 spring 自定义模块并且在 jboss-deployment-struture.xml 文件中包含了一个依赖项？以便找到所需的类定义？
作为参考，你可以参考这个链接， Spring module in JBoss 7
另外，请确保 jboss-deployment-structure.xml 对该模块有如下依赖关系。
<module name="org.apache.cxf.impl" export="true">
<imports>
<include path="META-INF**"/>
<include path="META-INF/cxf**"/>
</imports>
<exports>
<include path="META-INF"/>
<include path="META-INF/cxf"/>
</exports>
</module>
【讨论】：
我在 pom.xml 中包含 spring 依赖项。有什么办法可以避免 jboss 中的配置更改（安装 spring 自定义模块）并指示 jboss 使用类路径中的 spring？ 病毒，我已经在 jboss 中安装了 spring 模块并更新了 jboss-deployment-structure.xml 但仍然看到 org/springframework/context/ApplicationListener 的 NoClassDefFoundError。用 stacktrace 更新了帖子。 另外，如果我添加了你提到的 org.apache.cxf 和 org.apache.cxf.impl 的模块依赖项，我不会使用 JBoss CXF jars 吗？【参考方案2】：对于面临上述问题的其他人。这是解决方案。在 pom/classpath 中添加以下依赖项-
<dependency>
<groupId>javax.xml.ws</groupId>
<artifactId>jaxws-api</artifactId>
<version>2.2.9</version>
</dependency>
javax.xml.ws.Endpoint 在 JBoss 模块 jar 中可用。在部署期间出现冲突，因为它位于不同的模块中，并且您已删除 webservices 依赖项，因此 webapp 类加载器看不到它（我假设类加载器查找层次结构是这里的另一个问题，因为此类可作为 JDK 的一部分，最好是 JBoss应该尊重 JDK 类路径）。
【讨论】：
【参考方案3】：jboss-deployment-struture.xml应该如下
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<exclude-subsystems>
<subsystem name="logging"/>
</exclude-subsystems>
<exclusions>
<module name="org.antlr"/>
<module name="org.hibernate"/>
</exclusions>
</deployment>
</jboss-deployment-structure>
