Preface

    This is not a technical article to share , But this letter is from the heart 、 I'd like to share with you some of my experiences along the way . I have been working for two years before I know it , Growing up all the way . One is work experience , On the one hand, I am still exploring the unknown ocean of knowledge in every break time . During the process, I was forced to , Maybe a simple question will make you grope for a few nights , I even doubt whether I am doing useless work , But thinking about Kung Fu pays off 、 Practice makes perfect , Or I kept walking the same way . It's like going round and round , I love it .

My university

    I still remember when I was in college , It's easier , The pain is just a rush to hand in your homework . It has to be said that this period of university really needs to lay a good foundation , Don't waste it . However, there is a problem that many children's shoes have no direction , I don't know how to try , This is really fatal . Including myself , I didn't make good use of the precious time of University . I just feel OK , I still have a little understanding of some key points , Lay the groundwork for the future .

    My university is not very big , There are not many places for entertainment , There's not much to do , I walked into the library when I was idle , In fact, I have another purpose . I have to make fun of my college , There is no good library , The new library will not be built until our class goes out , There is no such blessing . Although there are few resources , I still found oneortwo good books . One is older , But it's very interesting ; One is new , Like Martian , I just feel that it is very good . At that time, there was not much pocket money , I worked part-time at school and saved some money , No matter how you feel, you just put them I bought it . In fact, you should not always worry about the cost of knowledge , You still have to spend what you should spend .

Approaching design patterns

      It seems that I found it in my sophomore year -- The old one , About Design patterns Of . I have to admire the author's humorous writing style , And in reason . Although I read it quite well at that time Laborious , But the author's writing is full of fun , So every time I read it, I feel more exciting . Only then discovered the encapsulation On the tall , But at that time, I still didn't have much understanding of encapsulation . Almost every time a person goes to the library , I would turn that book a few times , Slowly digest the knowledge , Although just The tip of the iceberg . Also don't say , None of my classmates seem to have learned much , Because they don't think it's a programmer's business , I can only say that they are really wrong . It turns out that , We college students should read design patterns . The first one to give you feedback is the soft test ,2019 In the intermediate examination for software designers , There is a big soft test question about design patterns , At that time, I did it smoothly , With one . I got full marks on that question that year , Also the highest score . This certificate is in the process of looking for a job , Give me a hand . But I have to tell you the truth , It is not design patterns that are difficult , But how to use design patterns in combination with requirements 、 Design your own pattern ( The principle is the same ) Is a little difficult . So you must read books and articles about design patterns well in college , Start doing experiments and so on . Tens of millions of others , And wasted the precious time to lay the foundation . And you can pick a more common pattern to learn , Of course, those with strong ability will learn all .

Approach the source code

    The second book I remember was about to leave school Bought , Because it's like the spark text , Just put it aside for comfort . But after coming out of school and entering the society , I still open it occasionally . I am busy after I work , Work on one side , You also need to rest , Therefore, the time spent on reading books every day is very little . And it's hard for you to understand the whole content , Boring , You will lose interest when you look at it , All the calories burned out . For all that , I still believe that one day , Prove that you can . So I always carry a few books , Are reluctant to throw away . I don't know if I've seen too many , The field of vision widened , The ability to comprehend has made a qualitative leap one day . You will find that the key point is still in a few knowledge , And it is something that we have learned but don't care about . Let me put it this way , The context of things , You have to know the fundamentals 、 The basic principle , To grasp the thread . And the foundation must be solid , Of course, it is difficult to be comprehensive , However, some key points that are weak can be supplemented .

    There is also the university is best to read the source code , Because there is a golden house in the source code . Although I missed , Because we don't recognize the correct way to open the source code , What elder martial brothers and sisters often advise . Later, he came out of the society , To make up for it , It's just that you should concentrate on your precious time . I am now specializing in MyBatis Source code , There have been many achievements . By the way ,HashMap The source code must also be read , In many companies, I like to ask questions during the interview . cram for HashMap After the source , In an interview , I hanged the trial officer for a while . The path of source code was difficult at the beginning , Many people don't know how to open it , So the capital was abandoned halfway , disqualified . So the best way for programmers is to have a guide , This can save time and energy , Quickly enter some areas of the industry . What others spend years or even ten years to understand , You can do it in less than a year .

    One's wisdom is always limited , We should learn to learn from and learn from excellent technical cows , have great experience .CSDN There are a lot of blog posts in the blog Very Good Of , Numerous good articles are shared by bloggers through experimental evidence , In particular, some have experimental conclusions . Of course , Also have your own judgment , Have their own evidence again . Another is the cost of time , This has to be taken care of by yourself , Make full use of network resources , In limited time , Gradually grow into a technical bull . What to read , Buy what you should , Youth leaves no regrets . Ask more why , Keep looking for answers , One day , The truth will come out .
