Ingress子路径无法路由至Spring后端服务问题咨询

现象 #

访问根路径/可正常跳转至项目UI，但其他子路径无法正确路由，返回404错误。

相关配置与测试信息 #

测试命令及结果 #

# 子路径请求返回404
curl http://xx.xxx.xxx.xx/api/general/detail -H "Host: project.k8s.com"
{"timestamp":"2022-11-27T14:29:31.899+00:00","status":404,"error":"Not Found","path":"/api/general/detail"}

# 根路径可正常访问UI
curl http://xx.xxx.xxx.xx/ -H "Host: project.k8s.com"

Spring后端日志 #

Tomcat started on port(s): 8080 (http) with context path '/api'

疑问 #

1. 后端服务集群外测试通过，控制器使用@RequestMapping("api/general/detail/")，Ingress日志也能看到请求记录，判断后端服务运行正常是否正确？
2. 除查看日志、检查Ingress配置、执行kubectl get all外，还有哪些排查方向？
