二、IntelliJ idea错误：找不到包或符号
最近，在使用idea时，突然出现了找不到包装或符号的情况。在确认你自己的参考存在之后，你可以尝试以下方法来解决它。以下是解决开发过程中遇到的相同问题的几种方法。我也在这张唱片里和大家分享，希望能对大家有所帮助。
关于MVN安装，可以使用idea的可视化插件界面或命令行模式。关于这个陌生的词，你可以自己做。
在idea安装目录的bin目录中找到如下图所示的两个文件，用编辑器add-dfile打开它们。Encoding=UTF-8在文件末尾，重新启动idea，然后打开流程图，发现中文可以正常显示。
最后，所有配置都正常，但输出仍然是乱码。此时，只有一种解释：idea在字体编码中犯了一个错误，但错误在哪里呢。经过多次的调查和寻找，终于有了一个。创意文件夹中的项目目录，并有一个编码。此文件夹中的XML文件
它记录了与您的一些文件相对应的特殊代码。为什么会有这样的代码？因为我之前不小心点击了右下角的代码，修改了它，然后被idea记录在encodings.xml中。当您再次访问它时，它将使用该代码。我说，你只认识你妈妈吗？只需删除encodings.xml中除UTF-8之外的所有内容（我所有的字体都是UTF-8）！
