1. git
Git is one of the basic tools Java developers need to master. Every Java practitioner should learn to use it. Git uses a version control system to manage various project collections. This is a completely free open source system, focusing on nonlinear workflow, integrity and speed. Distributed Extensions: Repositories can be used to create copies of development history. Link method: Git has a toolbox-based design and can provide well-defined models.
Basic toolbox design: Toolbox-based design can reduce the number of composite components.

2. Selenium
Selenium Web driver in Java is one of the important technologies that Java developers should know in 202 1.
Selenium provides a set of tools for testing Web applications using test frameworks. Selenium Web driver provides an open source API. It includes the automation features of some Web applications. The main elements of selenium include:
integrated development environment
Remote control/Se 1.0
Web controller/Selenium 2.0/3.0
Selenium grid
3. Jenkins
Jenkins is a technology derived from JAVA programming. Its continuous delivery and integration of open source automation can automate the software development process and support various version control tools.
Jenkins plug-ins can be integrated with code written in another language. Here are three reasons why you should choose Jenkins: it provides better quality than other software; Its automation system can manage integration; Jenkins developed faster.
4. User-friendly network services
The full name of REST is the concrete translation of state, which represents an architectural style and is the knowledge that Java developers must master. It improves the performance of Web services and defines scalability and performance constraints. This is one of the best choices for Java developers in 2022.
Its reconfigurable API is used for communication requirements in Web service development. If you know HTML, CSS, etc. , you will benefit greatly from RESTfulWeb services. The following are the characteristics of RESTful service:
The backbone client-server architecture provides features of server management, deployment and hosting, and can also help users use services and resources. It is essentially a shared computing model with shared resources.
Step 5 be safe in spring
Its main function is application authentication. Its J2EE servlet specification and EJB specification are two key security features commonly used by JAVA developers.
Spring Security supports various authentication models and integrates technologies such as HTTP, Kerberos, JOSSO, CAS and LDAP. Spring Security has a deep relationship with Java, and Java developers are strongly recommended to learn it.
6. Boot jumping 2
Spring Boot released a new version called Spring Boot 2. Among them, Spring framework is responsible for control, and Spring Boot is responsible for generating independent solutions with general configuration.
It mainly relies on JAVA baseline, BOM materials and cradle plug-ins, and its automatic configuration can provide security and responsiveness. It also provides technical support and improves the development experience. It is one of the basic tools that JAVA programmers should know, and its key features include:
Deploy undercurrents, jetties or male cats directly.
Reduce build configurations and provide dependencies
Create a stand-alone application in Spring
7. Angle or response JS
ReactJS is a JavaScript library dedicated to UI development, while Angular is a framework. JAVA developers should be familiar with these two key technologies. Wechat search readdot, reply to programming resources after attention, and get all kinds of classic learning materials.
Angular 2 is an open source We application framework. The main features of Angular include instructions, scopes, templates, comments, advanced dependency injection and sub-routers: ReactJS is used to develop mobile applications. The main features of ReactJS include free open source communication with the server.
8. Apache Park and Kafka
Apache Spark and Kafka are two technologies that Java developers 202 1 must master. They have released a stable version at the end of 20 18. Apache Spark is an open source framework for cluster computing.
Spark provides an application program interface for performing basic tasks such as 1/0, scheduling and dispatching, and also provides an equally open source stream processing platform. Especially Apache Kafka code is written in Java and Scala.
Kafka can use some basic APIs, such as Producer APIConsumer APl, Connector API and Stream APl.
