idea部署，web前端访问404错误

看了说明文档，解决办法说设置工程启动类的目录，idea...怎么设置启动类目录啊

网关使用kt问题

open idea部署，网关用的是kt，网关启动好没报错。但是网关页面访问直接404

希望部署文档再详细一些，遇到一些问题

No SecurityManager accessible to the calling code？找不到SecurityUtils这个类，是Shiro过滤器的启动顺序问题吗？

博主您好，我看到您提到由于Shiro兼容性问题以及个人精力有限已移除前端JSP页面、登录注册以及后台管理功能。我在启动Web服务访问login登录页面时出现错误：No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton.查阅相关资料后还是未能解决，请问这个是您所提到的兼容性问题吗？还是说我在某些地方没有配置好环境所导致的错误，百思不得其解。如果您有时间的话，能否给予我一个回复，万分感激不尽。
最后想咨询一下博主，可否为该项目建一个交流讨论群呢? 我认为这个项目非常具有学习价值，一定会有很多小伙伴加入！

能不能做个开发文档

新手看这个有点懵

请问分布式事务是如何解决的呢？

明面上说是dubbo 其实里面全是open feign

goodskill-seata里的依赖有一个拿不到

org.graalvm.buildtools
native-maven-plugin
build下的依赖找不到,需要加个版本号

收藏了，过一段时间拉下来

http://www.goodskill.com:8080/goodskill/web/login

{"timestamp":1653650764805,"status":404,"error":"Not Found","path":"/goodskill/web/login"}
会是哪里出了问题呢

compile error

error info

有相对完整的部署文档说明吗

有点卡壳了,先部署哪个？再部署哪个？一共部署几个应用能完成一个完整的场景演练。

无法打印sql语句

gradle分支依赖配置有问题，解决中。。

启动不了诶

快速开始启动SampleWebJspApplication失败

拉的master分支代码，启动web服务报错同时gooskill服务也报错，Caused by: java.lang.NoSuchMethodError: 'org.apache.dubbo.rpc.RpcContext org.apache.dubbo.rpc.RpcContext.getServerContext()'，看错误信息应该是seata里没有这个方法

SpringBoot分支GoodsKillRpcServiceApplication启动报错

### Welcome!

Welcome!

• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you expect to see?

Hi,
First of all - I really appreciate the work you've all done on Traefik - I think it's a great project. I've started using it not a long time ago and I love it.

I have a problem with access log - I cannot find any solution, to log real IP when the requests are proxied through CloudFlare. In access logs I can only see the CloudFlare loadbalancers IPs.

I know there are middlewares which rewrite CloudFlare headers for services, but I couldn't find a plugin which would put the real IP in access log.

I know that I can also use JSON format for access log and include headers, like X-Forwarded-For, but I really want to stick with the common format and see the real IPs there.

I've tried configuring ProxyProtocol, but it doesn't seem to help.

I don't have much experience with Go, and Traefik is a pretty big project, but from what I can tell, in pkg/middlewares/accesslog/logger.go on line 227, req.RemoteAddr is used:

...
core[ClientAddr] = req.RemoteAddr
...

I imagine that this is the part, where the source IP for a request is determined for access log.

Can you point me to a valid solution or determine whether that's a feature that could be implemented directly in Traefik?
