原因:集成spring-security了。把websocket请求拦截了,且不输出日志(因为一般spring相关日志级别是warn。debug模式下日志太多了
然后可以修改undertow日志级别看日志
bash
# 日志配置
logging:
level:
com.cas.wict: debug
org.springframework: warn
org.springframework.web: debug
io.undertow: debug
关键日志输出
bash
2024-07-11 10:15:43.292 [XNIO-1 task-1] DEBUG io.undertow.request.security
- Attempting to authenticate /ws, authentication required: false
2024-07-11 10:15:43.293 [XNIO-1 task-1] DEBUG io.undertow.request.security
- Authentication outcome was NOT_ATTEMPTED with method io.undertow.security.impl.CachedAuthenticatedSessionMechanism@7fedbc60 for /ws
2024-07-11 10:15:43.293 [XNIO-1 task-1] DEBUG io.undertow.request.security
- Authentication result was ATTEMPTED for /ws
发现可能是security对ws请求路径进行了拦截(为什么会拦截,猜测虽然写的是ws,但是发起的时候还是http,由后台升级成websocket)
解决办法:放开验证,单独写过滤器验证ws的请求
为什么以前用netty-websocket可以连接,那是因为netty没走spring-security的过滤器链
