 *1、打开idea安装目录的bin目录下的idea.exe.vmoption和idea64.exe.vmoption，在最后加上 -Dfile.encoding=utf-8
2、设置idea file编码。在菜单栏找到”File->settings->搜索File Encodeing，然后在IDE Encoding ，Project Encoding和Default encoding for properties files都设置为utf-8
3、设置idea server编码。在菜单栏找到”run->editconfigration” 找到”server”选项卡 设置 vm option为 -Dfile.encoding=utf-8
4、HELP->Edit Custom VM OPtions中加 -Dfile.encoding=utf-8 重启idea
