public Message<Object> uploadImgsFile(HttpServletRequest request) { //1 String
realPath =
request.getSession().getServletContext().getRealPath(File.separator);
System.out.println(realPath); //2 String realPath2 =
request.getServletContext().getRealPath(File.separator);
System.out.println(realPath2); return null; }
If you want to get the absolute path of the current project , And it's not here controller, At the same time, I don't want to pass it on request Parameters to service layer , You can do this
// code snippet // Now get the current path WebApplicationContext webApplicationContext =
ContextLoader.getCurrentWebApplicationContext(); ServletContext servletContext
