The most common development languages for back-end services are Java and C/C++.

The most common development languages for big data are Java and Python.

It can be said that Java is the research and development language with the widest coverage among Chinese Internet companies at the present stage. If you master the Java technology system, you can have a foothold in large mature companies, fast-growing companies or start-up companies.

A Java engineer needs to master a wide range of technologies, there are many technical people asked, in addition to master Java syntax, but also to systematically learn Java related technologies, today to share a: Java technology learning roadmap. I hope the following learning routes are helpful to you

1. Performance optimization

  • Understanding performance optimization

  • Mysql tuning

  • The JVM tuning

  • Tomact tuning

2. Microservices Architecture

  • Ramble on microservices architecture

  • Docker virtualization

  • Micro framework

  • Spring cloud

3. Source code analysis

  • Common Design patterns

  • Spring5

  • MyBatis

4. Architect toolkit

  • Maven

  • Jenkins

  • Sonar

  • Git

5. Multithreading concurrency

  • Java memory model

  • The lock

  • Development tool class

  • Atomic operation

  • The thread pool

  • Synchronized

  • Volatile

  • Concurrent basis

  • Concurrent collections

  • Del

  • Reference types

  • other

The first stage, Java foundation

JavaEE learning content from the Introduction to Java development, for you to start programming language literacy, what is a program, how to configure the Java development environment, Java programming process is what, Java has what features, how to run the program, these you can get the answer here. Next, we will introduce the basic syntax of Java programming, divided into 10 knowledge points, we will learn variables, basic data types, base, escape characters, operators, branch statements and loop statements, etc., in order to achieve the purpose of training basic syntax and logic ability. There are arrays, object orientation, exception handling, etc.

The second stage, JavaWeb learning

Web front-end development foundation and framework, Servlet and JSP in the Web backend application, Web backend development related topics, MVC and layered architecture, project development process and the use of CASE tools.

The third stage, Java framework

Frameworks are another way to store data in programs, which are more flexible than using arrays directly, and are widely used in projects. At the same time, framework integration development (SSH/SSS), RESTful architecture and mobile terminal interface design, third-party interface and online payment function, website Security and Spring Security application combat, complex user interaction processing and Spring Web Flow application, MyBatis application and SSM integration, We will deeply study the data structure and algorithm involved, which has a qualitative improvement to the technical depth of students.

The fourth stage, Java+ cloud data

Advanced Java tutorials, such as hundred-million-level concurrent architecture evolution, Linux foundation, Setting up tomcat environment and big data development cloud computing, are the high-end knowledge of Java technology. Among them, the project is interlaced with actual combat drill, and the real project of the enterprise is applied for students to learn, and the “secondary learning” of the knowledge system is carried out.

It’s all sorted out by itself! I’ll give it to someone who needs it! Incidentally for a wave of attention. We are serious about learning, and the offer from the big factory is likely to be won.
