Hi everyone: For the situation of Doris Fe of lacking `format style`, I'm trying to fix this thing. I made a draft `checkstyle` in the PR link <https://github.com/apache/incubator-doris/pull/9089>. I format the stable directory of FE with this style for reviewing. PR link <https://github.com/apache/incubator-doris/pull/9113>.
Influence Scope: Using the IDEA checkstyle plugin, this checkstyle will influence `5080 items in 890 files`. If you have any suggestions please reply or add it in this PR or ISSUE.
