Method for micro service of monolithic application

Abstract

The invention discloses a method for micro service of monolithic application. The method mainly comprises the steps of a call analysis stage, a module resolution stage and a framework adaptation stage, wherein a method call relationship among classes in application codes is obtained by analyzing byte codes in a package file, and thereby a call chain in the application is analyzed and a call graphis generated; for the call graph, all codes of which in-degree is zero are taken as entries, the entries are taken as starting points in turn to conduct breadth first search on a digraph to find all lower nodes, the starting point and the search result are taken as a to-be-split out micro service module together, according to the rule, an integrated item is divided into a plurality of independentmicro service modules, each module can be separately conducted with development and deployment, and the monolithic application also achieves quick micro service. The method for micro service of the monolithic application has the advantages that the input of the process for a monolithic framework to be converted into a micro service framework is reduced, the learning cost of the development is reduced, and the method can help the item be smoothly transferred into the micro service framework.

Description

technical field [0001] The present invention provides a simple and fast micro-service method, which mainly involves micro-service and micro-service transformation of single application, and can help non-micro-service single projects to be micro-serviced quickly and smoothly. Background technique [0002] The traditional code framework packs all functions (such as product display, product order, product payment, etc. of an e-commerce system) in a WAR package, basically without external dependencies, and deployed in a J2EE container (Tomcat, JBoss, WebLogic) contains all logic such as DO / DAO, Service, UI, etc. With the expansion of business scale, the software system implemented by this single-block architecture becomes more and more difficult to select technology, the maintenance cost increases sharply, and the scalability and continuous delivery capabilities become worse. The failure of any module may lead to The overall collapse of the system and the overload of any module...

Problems solved by technology

[0005] (2) Bounded: related functions will be integrated into a separate business unit and implemented in the form of a service

[0010] Although microservices bring huge benefits, it is not easy to transition from a traditional monolithic architecture to a microservices architecture
