使用wsimport工具（使用jaxws-maven-plugin:wsimport目标）为JAX-WS Web服务创建客户端API。生成的API工作得很好。现在，当引入安全性并且在更新的WSDL文件上再次运行wsimport时，我收到了一个错误：
[INFO] jaxws:wsimport args: [-s, C:\projects\EDMS2.0.0\docmgmt\docmgmt-client\src\main\java, -d, C:\projects\EDMS2.0.0\docmgmt\docmgmt-client\target\classes, -verbose, -p, com.abc.technology.retrieve.document.client.v1, C:\projects\EDMS\docmgmt\docmgmt-client\src\wsdl\RetrieveDocument\Technology-RetrieveDocument.wsdl]

我做了一些研究并尝试在wsimport中启用extension开关。在此之后，API成功生成。但在我认为wsimport之后，此身份验证部分被忽略了。
请说明在需要Web Service安全性时正确生成客户端API的正确步骤是什么？
