Dear Community:
When reviewing PR[1], I found that for `motan` and `tars`client, their `rpcExt` in `metaData` is redundant. In fact, we only need one piece of data at the method level. I submitted PR[2] to optimize them. In order to be compatible with the old version, I didn't change the reading logic of `org.apache.shenyu.plugin.motan.cache.ApplicationConfigCache#build` and `org.apache.shenyu.plugin.tars.cache.ApplicationConfigCache#buildClassDefinition`. If you are free, please see the PR[2] and help PR[2] to optimize them better. Looking forward to your reply. dragon-zhang [1] https://github.com/apache/incubator-shenyu/pull/3408 [2] https://github.com/apache/incubator-shenyu/pull/3417
