@changfubai 帮你看了一下，应该是这个问题。你可以去guide上找一个code style，然后本地代码格式化一下试试哈 https://github.com/apache/dubbo/blob/master/codestyle/dubbo_codestyle_for_idea.xml。

Fix the bug of the 2.7 branch (that is master) first, and then check whether this problem also exists in the 3.0 branch. After this fix, also check whether the 2.6.x version also has this problem.
