weblogic服务器中的CXF Webservice问题

Question

我正在尝试从我的 web 应用程序调用 web 服务，该应用程序在 Apache Tomcat 或 JBoss 等服务器上运行良好，但在 Weblogic 服务器中失败并出现以下异常。

有什么解决办法吗？

Answer 1

在您的 weblogic-application.xml 中，您必须将您的 JAXB 提供者定义为来自 cxf 而不是 sun 参考实现 (com.sun.xml...) 的提供者。

将以下内容添加到提到的文件中

 <prefer-web-inf-classes>true</prefer-web-inf-classes>

这会导致类加载过程的逆向。所以你为你的战争提供的类在来自 weblogic 的类之前加载。

编辑：

提供者的文档说：

用于定位要使用的提供程序子类的算法包括 以下步骤：

• 如果名称为 META-INF/services/javax.xml.ws.spi.Provider 的资源存在，那么它的第一个
  行（如果存在）用作
  的 UTF-8 编码名称 实现类。
• 如果 $java.home/lib/jaxws.properties 文件存在并且它可以被 java.util.Properties.load(InputStream) 方法读取并且它
  包含一个键为 javax.xml.ws.spi.Provider 的条目，然后
  该条目的值用作实现类的名称。
• 如果定义了名为 javax.xml.ws.spi.Provider 的系统属性，则其值将用作实现的名称
  类。
• 最后，使用了一个默认的实现类名。

所以，如果更改类加载还不够，请添加以下内容

 <prefer-application-resources>  
   <resource-name>META-INF/services/javax.xml.ws.spi.Provider</resource-name>  
 </prefer-application-resources>
