Writing in the front

Everyone knows that Github is a programmer’s paradise, with all sorts of cool open source frameworks, software, and tutorials. These things are great for learning and improving, so I came up with the idea of putting together some of the great Java open source projects on Github. If you feel good, welcome friends to star wave.

Many people have no idea what to learn about open source projects, and this article is sure to help you out.

Whether you want to see open source projects in the direction of Java tutorials, Java field projects, SpringBoot tutorials or microservices, distributed related open source projects, you can find the resources you need here!

The entire catalog of the project is as follows, which can be very detailed and perfect!

Part of the actual combat project is introduced

Most of the projects below are related to Spring Boot, since there is no reason to do SSM/SSH these days.

Mall system a total of 6 actual combat projects (PDF can be directly click to jump to Github)

Most of the mall systems below are more complex, such as mall. If you have no Java foundation and SpringBoot are not familiar with it, it is not recommended to over-study the following projects.

  • 1. Mall: Mall project is a set of e-commerce system, including the front mall system and background management system, based on SpringBoot + MyBatis.
  • 2. mall- swarm : Mall swarm is a system of micro-service malls, Spring Cloud Greenwich, Spring Boot 2, MyBatis, Docker, Elasticsearch and other core technologies are adopted. Meanwhile, Vue based management background is provided for convenient and quick construction system.
  • 3. Onemall: Mall, based on the idea of micro services, is a project combat under the B2C electric shopping mall landscape. The core technology stack is Spring Boot + Dubbo. In the future, Spring Cloud Alibaba will be reconstructed.
  • 4. Litemall: Another small mall. Litemall = Spring Boot back end + Vue administrator front end + wechat small program user front end + Vue user mobile end

Guns is fully functional, developed with the mainstream framework Spring Boot2.0+ and supports Spring Cloud Alibaba microservices). It is suitable for the rapid development scenario of enterprise background management website, and supports both monomer and micro services.
  • 3. SpringBlade : SpringBlade is a comprehensive project with the coexistence of SpringCloud distributed microservice architecture and SpringBoot single microservice architecture, which is upgraded and optimized by the business-level project. It uses Java8API to reconstruct the business code and completely follows the Coding specifications of Alibaba.

  • 5. COLA: From what I’ve seen, many companies develop their projects based on COLA. Compared to other rapid development scaffolding, COLA doesn’t provide much functionality that is already developed. Generate a good web backend project skeleton with a single – line command.

Well, I’ll just cover the tutorial and field project sections here, other open source projects would be too long to cover.
