java - weblogic 服务器中的 CXF Web 服务问题

Question

我正在尝试从我的 Web 应用程序调用 Web 服务，该服务与 Apache Tomcat 或 JBoss 等服务器配合良好，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 weblogic-application.xml 中，您必须将 JAXB 提供程序定义为来自 cxf 的提供程序，而不是来自 sun 引用实现 (com.sun.xml...)。

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发生逆转。因此，您在 war 中提供的类会先于 weblogic 中的类加载。

编辑:

提供商的文档说:

The algorithm used to locate the provider subclass to use consists of the following steps:

• If a resource with the name of META-INF/services/javax.xml.ws.spi.Provider exists, then its first
  line, if present, is used as the UTF-8 encoded name of the
  implementation class.
• If the $java.home/lib/jaxws.properties file exists and it is readable by the java.util.Properties.load(InputStream) method and it
  contains an entry whose key is javax.xml.ws.spi.Provider, then the
  value of that entry is used as the name of the implementation class.
• If a system property with the name javax.xml.ws.spi.Provider is defined, then its value is used as the name of the implementation
  class.
• Finally, a default implementation class name is used.

因此，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>

到 weblogic-application.xml
