Servletconfig.getservletcontex The T method obtains the ServletContext object.
You can also use the This.getservletcontext method
Example:
//Get ServletContext in two ways:
Method One: Obtain by ServletConfig
ServletContext SC1 = this. Getservletconfig (). Getservletcontext ();
Method Two: Get directly through the servlet class
ServletContext SC2 = this. Getservletcontext ();

2. The client is more clean and tidy. You can also "slightly" Avoid using game resources by others.
3. Avoid reading files that fail due to inconsistent file names
