With this document, you can get a salary increase of 10K
Last year, in 2019, have a friend, bugging me all day to interview questions to me, this guy, belong to the Buddha life, patience is extremely high (impending nuptials), is it really for me so there is no way, just to find an interview document from the Internet, and then I was ready to give him, unexpectedly, a few months later, the outbreak has just get better, He suddenly want to please me to dinner, but also personally cooking, I went to a face of meng, and then he said to me, he is in addition to its own technology, the interview, a lot of knowledge to ask is in the document I gave him, and he just goes well into the company, pay close to 10 k, successful reversal homers, so please me to dinner.
Success of a promotion and pay increase, 10 k may say that is not a small increase, in addition to happy for him at the same time, also in wonder, with a copy of the document, actually helped him so much, of course, have to say, in the programmer, technology is the absolute principle, technology, and document that the cow force, also is just a hollow, really during the interview, flawed, so, Learning is still very important. It’s never too old to learn
But learning, there are skills, I summed up the following points
1. Have your own plan and set a learning time for yourself to finish what you learn at what time. You can take job-hopping as the learning goal and practice to test the learning results.
2. There is a corresponding learning structure. Nowadays, many people feel that they are learning, but the knowledge they learn is relatively small or close to being eliminated in the market, which is basically a waste of time
3, greed is not bad, it is best to have accurate learning, at this time, there is an old master to take you, his experience will help you save a lot of time, but also can help you take many detours
4, perseverance, really, because Java is an old programming language, although python such a sudden rise of the language, but in a short period of time, Java power is still quite large, but this also leads to, want to enter Java or have a better development, the test for you will also increase, so, in learning, Need to learn a lot of things, so that you will be persistent, has been learning, every day a little accumulation, over a long period of time, there will be a very significant effect
Well, said so much, next, I put that help a friend raise salary 10K document contribution and share with you

Second, the Spring principle
It is a comprehensive, enterprise application development station solution that runs through the presentation layer, business layer, and persistence layer. But Spring can still be seamlessly integrated with other frameworks

The database
Database storage engine is the bottom software organization of database. Database management system (DBMS) uses data engine to create, query, update and delete data.
