Java 3 years, the recent interview in Tianjin and Beijing some experience, simple zookeeper Dubbo Spring build (Basic recommended)

Recently changed jobs, interviewed a branch, with a little bit of income, as I said in my previous article, Beijing is now using a lot of technology, the company is not many companies in Tianjin, always feel that learning needs to have a simple plan, rather than a mind smashed into, see a desperate look, technology this thing, It still needs some skill to learn.

First, give yourself a clear orientation, 3 years of technical staff, what the company needs, what you can do, do not rule out certain cases, in a company, if you can stay for 3 years, large companies, generally will not have the opportunity to sit in the position of the project manager, at most is a good technical developer, Responsible for the development of a module, the small company's words are not clear, business is not so much worry, do not consider the impact of various aspects. So most will say 3 years is a threshold, from this time, you have been able to independently responsible for the development of a module, independent analysis of requirements, understand what customers want, to make a program without too many bugs.

Thank you very much for this opportunity, if I have been staying in the company now, I really do not know in two years, it should be unemployed, now I find work is not too easy, there is a special kind project manager, although some of the insult, but still give me some advice, I have no face on the simple reason is that the technology is too single , this is the key, if you need to be alone in charge of the development of a module, first of all, your technology does not require much depth, at least all aspects of the technology you need to have a certain understanding, that is, the breadth of technology, this is the basic threshold, if even this threshold can not reach, will not have the interviewer specifically asked you, what HashMap basic principles , or concurrent hashmap is how to achieve the locking mechanism, I spent a lot of time in the early study of clear collection data structure and additions and deletions to check the mechanism of the implementation mechanism, found that there is no use, no interviewer asked you so thin, There were two times even I wanted to say, the result is cruel interruption, understand the company's project is very important, but not particularly important, introduced to have a certain logic, specific technology to talk about a part, you understand that part on the line, after all, the interviewer does not understand your project, you can think how to say, pay attention to justify.

The purpose of the company recruiting more than 3 years of experience for developers is not to let you structure a project alone, but to work. Work. Work. The important thing to say three times, the depth of the technology needs, but these are added sub-item, the basic thing is breadth, a few companies just understand, ready to spend a few days to the Internet technology to understand some of the market, at least when the interviewer asked you the relevant technology, your answer is not to know, or did not use. I can set up a simple structure, understand the basic work mechanism and ideas, details can be later work to study again, to the interviewer's feeling is, to be able to work, but still need to improve, so as to continue to chat, instead of this use useless, the use of nothing, generally such, two words, no, And some of the problems that you encounter when building a framework, and how you overcome them, can also be used to say that making your conversations seem more real and giving people the feeling that the child has really done it.

Yesterday reference some articles, set up a Dubbo Zookeeper Spring Integration Framework, feel quite simple, the only disadvantage is Ali's Dubbo admin With the 2.5.8 jar package, but did not upload to the warehouse, on the internet to find a lot, did not find that the whole of my project build has been unsuccessful, malicious very heart, spent 13 C currency down a war package, deployed up later found an error, enough pit. Fortunately the admin function is limited, may not, in the message processing aspect influence is not very big, up zookeeper after, Service,provider,consumer three projects, completes the information transmission.

Specific links are as follows: http://blog.csdn.net/zgsdzczh/article/details/78664561

This is built with idea, and there are some differences between the references to the Maven jar package and Eclipse, where in the real world it is necessary to import the related SPRING,ZOOKEEPER,DUBBO packages separately in provider and consumer, which is just to achieve the basic functionality, Other jar packs are not required. Today is ready to look at the original rational things, casually looked at, or too simple, or too complex to understand, have the opportunity to share.

In addition to this part of the knowledge, NoSQL this piece, redis,mongodb,memcache these three more mainstream, concrete has not begun to see. MQ this piece is also involved.

Front end this piece, JS and jquery are the base, jquery components Easyui This is something that someone asked me.

Come here and get here today.
