Just contact J2EE, found that J2EE entry is relatively easy, but full of design patterns, frameworks, functional packages, etc., is very annoying. If only one frame is often used, there is IDE support, it is used to the development efficiency and very high. But I want to be self-study or I want to be something, I really pick the eyes, that is, too much choice is equal to the meaning of the choice, the forum is relatively bad to argue on the framework, but it is still a good sentence. These patterns, frames, all program habits, or you are used to thinking about solving problems is a good frame.
The current framework is still simple, there is no in-depth use, just feel. It has been integrated with many functions, and the improvement of work is affirmative, but the cost of learning cannot be too low, at least for me, there is basically no design pattern, there is no such class when I go to school, I also have a variety of java The pattern is full of flying, it turns out to use M $, there is nothing choice, it is to do it according to what it says, and it will save things.
I really don't understand that J2EE is so complicated. Migrant manufacturers have desperately designed a variety of simplified workloads, improve the efficiency of all kinds of tools, let everyone learn, and more and more things, it is endless. It is not conducive to programmers to improve proficiency, productivity, I feel that the upper part will go, and I can reveal M $ thing. I often say that the technical content is not high, and the structure is not elegant cloud. Originally, as long as you make something, it is good. Some situations are in the efficiency, and who look at the code, now there is a post-maintenance and 2 demand for 2 times, but it is not possible to avoid this problem.
At present, how to deeply learn J2EE is more confused, technical day and new month, feels no way.
I have written a bunch of words, I don't know what to say ...
