Among them, one of the more common attacks is CC attack. It simply and roughly sends a large number of normal requests, exceeding the maximum capacity of the server and causing downtime. What I encountered was a CC attack. At most, about 20 IP addresses around the world sent requests in turn, with the number of requests per address ranging from 200 to 300 times per second. When I read the log, I felt that those requests poured in like a flood. In the blink of an eye, there were a lot of requests. In a few minutes, the volume of the log file increased by 100MB. To tell the truth, this is only a small attack, but my personal website has no protection, and the server is still shared with others. This kind of traffic immediately goes offline.One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.第六季确定为最终季。但其实，还是没有看破一切。所以想要救张良，还是得自己想办法。System.out.println ("after decorator!
