new learning roadmap java

I know a lot about hobbies Java How difficult it is for people to learn , Specially organized the new version of the learning roadmap , No matter you don't know computer , Or has entered the development of cattle , This routine must not be missed ! Chuanzhi education's black horse programmers share free video tutorials for up to 12 More than 10000 hours , Tens of millions of people have benefited .2021 We don't forget our original intention , Move on . The purpose of the roadmap is to share , major , facilitate , Let's love Java People who , Can study equally . From today on, no more excuses , Don't say you want to learn Java But there are no resources , Get moving ,Java Waiting for you to explore , You are only one step short of a high salary !

2021Java The latest learning roadmap is fresh

The first stage :Java From language introduction to mastery

Pre school guidance :

Learn any programming language , The first thing to learn is basic grammar , Turn on Java The first step in learning , Of course, it is to have a deep understanding of the fundamentals of computers 、 Basic programming syntax , object-oriented , aggregate 、IO flow 、 Threads 、 Concurrent 、 Exception and network programming , These are what we call JavaSE Basics . When you've got it , You can do things like : The thunderbolt download software installed on the computer 、QQ Chat client 、 Attendance management system and other desktop applications .

The second stage :JavaWeb The core technology

Pre school guidance :

Master the front-end technology can only do static website , But its page data remains unchanged , The dynamic website can display different contents according to the changed data in the database , More widely used , So programmers have to learn how to do dynamic websites . Use Java Do dynamic website , We need to learn Servlet、Filter、Session、Cookie、JSP、EL expression 、JSTL Do dynamic website complete knowledge system , After learning, you can develop OA System 、 Content sites 、BBS etc. .

The third stage : Programming enhancements

Pre school guidance :

I learned from the front JavaSE Basics , But it's not very efficient in enterprise applications 、 Poor expansion , Programming enhancement is for JavaSE Strengthening the foundation , Will be targeted to improve the program processing business execution efficiency 、 Enhance program extensibility . Programming reinforcement will enhance advanced multi-threaded learning , Involving thread memory 、 Thread communication and other technologies . After learning , Can increase the knowledge of an intermediate programmer , Whether in the interview process or in the future, lay a good foundation for the in-depth technology .

The fourth stage : Project management tools

Pre school guidance :

Company development is team collaborative development , In order to better grasp the actual development , We also need to learn about common project management platforms 、 Version controller 、 Project building tools and automated deployment tools . Project development must have version upgrade , Managing the project schedule and release needs Git、Maven、Sonar Such a system platform . After learning software project management , Will master the actual development process of the whole project and the collaborative development tools used in the whole project development process .

The fifth stage : Popular framework technology

Pre school guidance :

Javaweb After mastering , Already have the ability to develop actual projects in the enterprise , But it's inefficient , A lot of code , Long development cycle 、 High development cost . Some excellent framework technologies are widely used in enterprises to solve the above problems , So we also need to learn framework technology , The mainstream of project development is Java Framework technology has SpringMVC、Spring、MyBatis、MyBatis Plus、SpringData etc. . These framework technologies are necessary skills for a good programmer .

Phase 6 : Distributed architecture

Pre school guidance :

Technologies that need to use distributed microservices . After studying this stage of the course , Can have a large SOA Architecture and microservice architecture capabilities , Be able to master the necessary technology and practical experience of large micro service projects . In the process of enterprise development , The number of business and users is increasing gradually , In order to ensure the availability of the system , The more complex the system is , More R & D personnel , It's hard to maintain a complex system together , Often modify part of the content , It leads to pulling a hair and moving the whole body , So we need to upgrade the system architecture ,

The seventh stage : Server technology

Pre school guidance :

Whether it's native Javaweb Development , Or use a framework for development , Finally, the project needs to be released to the public to be accessible to people all over the world , The server board can solve this problem , So server is a necessary technology for project release . This section includes virtualization and web Application server learning , It mainly includes the following modules :Vmware, Virtual machine software ;Linux, A system dedicated to servers ;Nginx, Reverse proxy server in cluster deployment ;Tomcat, The main server used for project release . After studying this plate , We can publish the developed project to the server , And then your partner can access it remotely , Super cool !

The eighth stage : Business solutions

Pre school guidance : Some common business scenarios will be encountered in enterprise development , Such as : Search engine 、 cache 、 Timing task 、 workflow 、 Report export 、 Log management 、 System monitoring, etc , Well, these common solutions also have excellent free open source middleware out of the box , available . Such as :ElasticSearch、Lucene、Solr、redis、MongoDB、slf4J、ECharts、Quartz、POI etc. . Business solutions and technical difficulties of business solutions course , Solve the problem of enterprise development 90% The above pain points and difficulties .
