Spring Boot 2.7.0集成JAX-WS 1.9启动Tomcat失败求助

在Spring Boot 2.7.0环境中集成JAX-WS 1.9时出现启动异常，使用的依赖版本为jaxws-spring v1.9、spring-boot-starter-parent v2.7.0，未配置web.xml，服务类已添加@WebService与@SOAPBinding注解。

启动时抛出org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat错误，提示运行时描述符"/WEB-INF/sun-jaxws.xml"缺失，但该文件已放置在/src/main/resource/WEB-INF/目录下。

仅在使用自定义的JaxWsListener（封装WSServletContextListener）时会触发此问题，移除该监听器后Spring Boot可正常启动。同时已实现自定义JaxWsServlet（继承WSServlet），并通过/WEB-INF/soap-jaxws.xml配置定义端点，而WSServletContextListener会硬编码解析该文件。
