Why respond to programming?The traditional servlet model came to an end.Traditional Java server programming follows the servlet specification of the EE, a threading-based model: Each HTTP request is handled by a single thread.The disadvantage of the threading model is that each thread has to handle the read and write operations of the socket itself. For most requ
need to occupy CPU and only with resources such as I/o,oembios, so that other threads that need to occupy CPU resources have access to CPU resources. Fundamentally, this is the ultimate goal of multithreaded programming. [The first question to be clarified] As with the difference between programs and processes, to master multithreaded programming, the first thing to understand is the difference between t
In "The dynamics of Java programming, part 1th," I introduce you to Java programming classes and class loading. This article describes some of the Java binary class format related information. This month I'll explain the basics of using the
Security | programming | server Overview and Overflow I. Overview Writing secure Internet applications is not an easy thing to do: just look at each professional bulletin board to find a continuous security vulnerability report. How do you make sure your Internet applications are not as full of vulnerabilities as other people's applications? How do you make sure your name does not appear in an embarrassing major security incident report? If you use th

form a real progress bar (instead of the indeterminate version I use). This ability will give you a good reason to refactor a method at run time, because the overhead of tracking any independent method can be very obvious. You can add "Debug" mode to the progress bar, regardless of whether the method call contains @status annotations and report all method calls that occur during the sampling process. This is invaluable to any developer who wants to debug deadlocks or performance problems. In f
