Java-JBoss EAP 7排除Web服务子系统给NoClassDefFoundError：无法链接EndpointDefinitionParser $SpringEndpointImpl

2023-08-24 23:09:10

在Jboss EAP7中,我想在pom.xml中添加cxf maven依赖项,并在jboss-deployment-structure.xml中排除了webservices子系统,因为要使用在pom.xml中定义的我自己的cxf版本.但是在服务器启动过程中遇到以下异常-

Caused by: org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.apache.cxf.jaxws.spring.NamespaceHandler] for namespace [http://cxf.apache.org/jaxws]: problem with handler class file or dependent class; nested exception is java.lang.NoClassDefFoundError: Failed to link org/apache/cxf/jaxws/spring/EndpointDefinitionParser$SpringEndpointImpl (Module "deployment.SomeApplication.war:main" from Service Module Loader): Failed to link org/apache/cxf/jaxws/EndpointImpl (Module "deployment.SomeApplication.war:main" from Service Module Loader): javax/xml/ws/Endpoint

        <subsystem name="webservices" />
        <subsystem name="logging" />

更新：
在JBoss中安装了Spring模块,并更新了jboss-deployment-structure.xml

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <!-- Picket link configuration -->
            <module name="org.picketlink" services="import"/>
            <module name="org.springframework.spring" export="true" meta-inf="export"/>
            <module name="org.apache.cxf" export="true" />  
            <module name="org.apache.cxf.impl" export="true" />  
        </dependencies>

            <subsystem name="weld" />
        </exclude-subsystems>
    </deployment>
</jboss-deployment-structure>

现在看到下面的错误-

解决方法:

对于其他面临上述问题的人.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>

JBoss模块jar中提供了javax.xml.ws.Endpoint.在部署期间会发生冲突,因为它位于不同的模块中,并且您已删除了webservices依赖关系,因此webapp classloader看不到它(我假设classloader查找层次结构是这里的另一个问题,因为此类可作为JDK的一部分使用,理想情况下为JBoss应该尊重JDK类路径).
