The problem of java classes that cannot be compiled normally in idea

    I encountered a problem recently. Because the code in a class in the project is automatically generated, and the number of lines in this class is large, the idea editing tool cannot load the file normally, and other classes that reference this class report errors.

    Solution: Open idea.properties in the bin file in the installation directory of your idea, and then modify the value in the configuration file: idea.max.intellisense.filesize. Say your class has 100,000 rows. Then you just need to modify the value of this to be larger than 100000, and then restart the idea.
