###【404】The origin server did not find a current representation for the target resource or is not willing to disclose that one exists

The server started successfully , But the default page can't be accessed , I checked some solutions online, but they are not applicable , Later, I saw a big man mention the project web.xml Configuration of , modify url Address , So we found the cause of the problem .
Before restarting the server is difficult , I changed the module name and directory name of the module , Find the corresponding module .iml file , Sure enough, a line of code in it has not been changed .
Here's the picture ： Change the code to the current corresponding module name , Problem solved successfully .
