java - 将 CXF 自顶向下 Web 服务部署到 Weblogic 12.2.1 时出错

Question

这是一个使用 cxf-codegen-plugin 创建的简单的自上而下的 CXF Web 服务，但在将 war/ear 文件部署到 Weblogic 12.2.1 服务器时出现以下错误:

cxf-rt-transports-http Version 3.1.4
cxf-xjc-runtime Version 3.0.5

Answer 1

neethi.jar 和 cxf-rt-ws-policy.jar 存在一些冲突，当我从 war 文件中删除 cxf jar 时，这些冲突得到了解决。
