What level of Java can you go out to find a job! Get these techniques!
1.JavaSE content
Environment construction, basic grammar, object-oriented, array, collection, common API, IO stream, reflection mechanism, multithreading, network programmingClaim:
Use these basic knowledge to write a socket chat room and typing game; the foundation is not strong, the cave is shaken.
2. Database
MySQLClaim: After
learning Mysql, you must practice SQL yourself, especially select. If you don't practice, you will be abolished.
3. Front end
Three major technologies: HTML, CSS, JavaScript, learning two frameworks (JQuery and Bootstrap)
Claim:
Handwriting a static page (imitating a page), if you don't practice, it is easy to forget the code later.
4. Backend
XML, MVC architecture mode, Servlet, Filter, JSP, EL, JSTL, AJAX, proxy mode, factory mode, database connection pool
Claim：
- Deep understanding of MVC architecture pattern
- Practicing an MVC model project (servlet+Ajax+Mysql+JQuery+JDBC)
[such as: OA management system, supermarket order management system, purchase order management system]
aims to change MVC thinking
. The more you practice, the better, the more you practice The easier it is to learn the framework later.
5. Project Management
Maven, Git
Claim:
Nothing is required, just do it by yourself.
6.Frame
Spring, SpringMVC, MyBaits must learn
Struts2, and Hibernate. If you
don't have a teacher, you can learn it by yourself. It is estimated that no one month will be endless. If the previous MVC architecture pattern is not well studied, I will give up here. . .
Claim：
- Build your own framework environment (make a backup, 100% useful for entry)
- Upgrade the project of the MVC architecture pattern that I practiced before
[1.
Change Servlet to SpringMVC] [2. Change JDBC to MyBaits]
[3. Join Spring decoupling MVC] - Practice two projects
such as: ssm customer relationship management system and other projects
7. Market demand
Learn SpringBoot
and practice more than 2 projects with SpringBoot
note: It’s
hard to learn Springboot, just go back and learn Spring again.
At this step, you can interview
8. Add Root Ham
Dubbo, Zookeeper, SpringCloud, MQ, Nginx, Redis, Linx, Vue, multithreading, design patterns, JVM optimization, algorithms
Add ham to the lunch
Feelings:
1. Experience:
It has been two and a half months since the Ganzhou project ended on September 25.When I first came back, I thought I had done a project and just had a direct interview.
1. Debriefing + Internship + Resume: One week
2. Looking at other people's summary notes: One week
3. Continuous interview: Two weeks
4. Self-doubt, one week off
5. Two weeks of review, Mysql, redis, concurrent programming, Spring
6. Interview For two weeks, when I thought there was no problem, the result was not as smooth as I
expected. 7. In the past few days, I was a little anxious and worried that going to the interview again would waste the interview opportunity. I don't want to go very much, sad. Sometimes I cry and I don’t want to disappoint others.
8. It seems that many questions about interviews are also reflecting on themselves.
2. Question:
1. Think back to your two previous failures. In fact, it failed because it didn't invest in what should have been invested, and it was just fruitful.2. In fact, everyone's experience is different, starting time zone and ending point are different, everyone just walks in their own time zone, neither fast nor slow.
3. Still very afraid of letting others down. Although I have been working hard, my actions are as good as possible.
4. Believe in single things and people too much, like a frog in the bottom of a well. I thought I saw the world.
5. To be realistic, life is not for anything, you have exhausted everything if you can live.
