骆驼CXF:一种方式方案是访问用户主体，导致NULL指针异常

Question

找到了WebSphere Liberty个人资料17.0.0.4的此问题。当我发出单程请求时，这将导致无效指针。它可以与请求响应服务一起工作。

我是一个春季启动应用程序。该代码可作为具有嵌入式tomcat容器的独立Springboot应用程序正常运行。

当在WebSphere Liberty配置文件中运行时，错误发生。我已禁用WLP中的嵌入式容器

部署

Answer 1

我通过覆盖defaultcxfbinding。CFX JMSCONFIG可以通过将"创建"为false创建creteSecurityContext来完成此操作。甚至HTTP传输也应该具有此功能

@Overridepublic void populateExchangeFromcxfRequest（Exchange cxfexchange，org.apache.camel.camel.exchange camelexchange）{

Message cxfMessage = cxfExchange.getInMessage();    
cxfMessage.put(SecurityContext.class, null);        
super.populateExchangeFromCxfRequest(cxfExchange, camelExchange);

}
