Introduction

Java chassis is an open-source microservice development framework managed by the Apache Software Foundation. It was first donated by CSE. Till now, hundreds of developers have contributed to the project. Compared with Spring Cloud, Java chassis provides the following functions:

• Flexible and high-performance RPC implementation. Based on open APIs, Java chassis provides unified description of different RPC development modes, standardizing microservice API management and retaining flexible usage habits of developers. Based on reactive, Java chassis implements efficient communication protocols such as REST and Highway, and is compatible with traditional communication protocols such as Servlet.
• Rich service governance capabilities and unified governance responsibility chain. Common microservice governance capabilities, such as load balancing, rate limiting, and fault isolation, can be used out of the box. In addition, a unified governance responsibility chain is provided to simplify the development of new governance functions.

Like Spring Cloud, Java chassis can also use Spring and Spring Boot as basic components for application development. However, Java chassis provides independent RPC implementation. Therefore, functional components that depend on Spring MVC are restricted, for example, Spring Security.
