My Maven Project Structure is Like Below.I want To Load Css In mainMenu.jsp File.
<link rel="stylesheet" href="../Main.css">
Above Line Is Not Working.So How Can I Load Main.css in mainMenu?
Don't confuse your WEB-INF layout with what the browser sees. Move your Main.css to "webapp" (or, more commonly "webapp/style"), and then reference it as "Main.css" (if in webapp) or "style/Main.css" (if in webapp/style).
Under WEB-INF, you typically only want files which are processed server-side, eg. JSP (when using a ViewRenderer) or web.xml.
Spring Boot automatically adds static resources located within any of the following directories as mentioned here:
/META-INF/resources/
/resources/
/static/
/public/
Hence, the mistake you are making is by placing static content in wrong directory.
