問題描述：Idea平時好好的，突然就打開后掃描完畢后自動退出。網上說修改idea.exe.vmoptions文件的Xmx,還是不行。
1.進入當前用戶的根目錄(比如我本地是:C:\Users\admin,一般是打開Cmd窗口顯示的默認目錄)，查看日志文件java_error_in_idea_XXXX.log(比如我本地文件為:java_error_in_idea_3532.log),一般情況下，日志文件一開始會有“A fatal error”的提示信息，如下:
1 # 2 # A fatal error has been detected by the Java Runtime Environment: 3 # 4 # EXCEPTION_ILLEGAL_INSTRUCTION (0xc000001d) at pc=0x00007ffe54a146fa, pid=3532, tid=0x000000000000220c

2.根據提示，發現提示信息中有"Problematic frame.......mybatisplugin....."的信息，說明是mybatis plugin的問題導致的
3.刪除該plugin tmp文件,進入根目錄下的.IntelliJIdeaXXX文件夾下的如下目錄(我本地為:C:\Users\admin\.IntelliJIdea2019.1\config\plugins),刪除mybatis的文件夾，然后再啟動idea,問題消失
