Company.com has decided to use the FUBAR Application Server to host their web application. Unfortunately, the FUBAR Application Server uses the server machine’s file system for its JNDI namespace. Every JNDI lookup performed in the web application is translated into a file 1/0 operation, which results in very poor performance. Which J2EE pattern can help with this performance issue?()A、 Transfer ObjectB、 Service LocatorC、 Intercepting FilterD、 Model-View-Controller
