zookeeper'Dubbo path has come out many strange nodes

[Liubey]

black is start with com.* in addition，we use "GenericService mode" to invoke the real services

[Liubey]

many many nodes, cause we can‘t connect zk to list these paths in cli.

这个 2525 是 ／ 多次 encode 出来的

[chickenlj]

I have encountered this problem before, you must have wrote ZK from other systems. Please check your program. @DocEcho suggest one possibility.

不止一次遇到这个问题了，请教一下各位大神，非常感谢！

1. 对 / 的多次编码造成，但是为什么会出现 / 并且 多次编码？
2. chickenlj 提到 other systems，是指 zookeeper 从 windows 链接 unix？
3. 有哪些情况会出现问题？
4. 根本原因是什么？如何规避？

[Jukewu]

同样遇到过这个问题，没找到原因

[Liubey]

为什么要close，还没解决问题呢 @chickenlj ，再讨论讨论呗

Hi, Eason

This is very likely to be a env-related problems, do you have other systems writing data to ZK registry except for dubbo framework? I mean systems like dubbo-admin, which will write data to registry. Please remove the mosaic on the picture, so we can see this data was created by which part/feature.

Please send more details of this issue to dev@dubbo.apache.org for further discussion. We tend to discuss questions like this there.

interface命名中含有特殊符号，然后多次转义的情况下会这样。　 转义是在什么情况下执行的？什么情况下会再次转义？　 我们有接口使用的是子类用到了$　出现了多个252524。 zk节点下面都有[consumers, routers, providers, configurators] 且下级内容均为空，很大可能性是由dubbo写入的。
