默认命名空间public能不能把名称和id都定为public，这样可以和nacos的客户端保持一致

[zzutligang]

如题

[heqingpan]

nacos的默认命名空间id有历史包袱，不同的版本有不同的默认值。
老版本是空串，新的版本是public。

请求时r-nacos对两者做了兼容，但返回值只能返回一种。
目前是和老版本保持一致，配置中心返回的是空串；客户端监听时如果不兼容，就要设置准确的值，之前的客户端空串与public两个命名空间可以分别试一下应该会有一个可以用。
（也可以考虑不用默认命令空间，这样可能规避这类问题）

你现在用的客户端是什么版本？

为了兼容老版本客户端，r-nacos不好直接改成public。不过后续可以考虑支持通过配置指定返回的默认命名空间id为public。

我也有相同的需求,从nacos迁移过来时都是默认的public命名空间.

但我在代码命名空间public时可以连接上r-nacos配置中心为空白字符串的命名空间id.

r-nacos似乎自动的在命名空间中注册了一个public/public的命名空间.
如图

@zzutligang 新发的v0.7.4版本已经在输出加了适配，nacos新sdk(使用grpc协议的sdk)。默认命令空间统一使用public即可。

上面的命令空间是自动根据注册配置中心的内容自动创建的，在控制台中这两个使用哪个效果都一样。
SDK的使用时，之前输入已经会自动转化。输出在最新的v0.7.4版本中也做转化（统一转化为public)。

目前使用理论上应该不会有问题，你们可以抽空验证确认一下。

好的👌感谢
我昨天将几个服务迁移在开发环境时在命名空间上没有遇到问题
注册中心和配置中心都能正常使用并启动
但是遇到了一个新问题是我有一个项目的nacos client java sdk的jar包是2.2.3，在启动时连接nacos会提示一个NPE，印象里提示connet error client status starting，将maven版本回退到了1.4.1就可以了，在文档中也看到了http client是1.4.x
不知道是不是还没支持2.x 3.x的jar包？不过我觉得这个1.4.1也够我用了
目前不在电脑旁，如果需要更多报错信息我可以回家后贴出来

@Mzlalal 你用的r-nacos是什么版本？

2.2.3版本如果是连java的nacos没有问题，连r-nacos有问题的话，可以把对应日志提供一下；也可以换成2.x较新的版本试试(比如2.4.3或2.5.1）。

如果确认是兼容问题，我这边会尽量兼容。

[Mzlalal]

我r nacos目前用的release下载的最新的r nacos版本

项目使用2.2.3的maven java sdk连接java官方nacos 2.2.3版本没有问题
我晚上回去贴一下日志
