A restart-free operation and maintenance upgrade method, system, device and medium

Abstract

The invention discloses a restart-free operation and maintenance upgrade system, method, device and medium, comprising: a request receiving module for receiving access requests; a file acquisition module for searching and obtaining business logic files corresponding to the access requests; running cache The module is used to store the first executable code corresponding to the access request; the update judgment module is used to judge whether the business logic file corresponding to the access request needs to be used to update the first executable code; the compilation module is used to use the corresponding The business logic file updates the first executable code, compiles the business logic file, generates the second executable code, and updates the first executable code to the second executable code. The effect of the invention: the web project can be updated and upgraded without stopping the service.

Description

A restart-free operation and maintenance upgrade method, system, device and medium technical field The present invention relates to the field of website operation and maintenance, in particular to a restart-free operation and maintenance upgrade method, system, device and medium quality. Background technique In traditional JAVA development process, generally adopt the mode of static compilation to carry out, specifically, first use The JAVA compiler compiles the java source code to generate bytecode, which is specific to the file, that is, the corresponding Class file. file, and then the JAVA virtual machine generates the corresponding binary executable code according to the content of the CLASS file to execute it. [0003] But in the process of Web development, because in the running process, the Class file must be started at the same time, also That is, the bytecode is loaded into the memory, so when upgrading, the server must be stopped to achieve the code upgrade...

AI Technical Summary

Problems solved by technology

[0003] However, in the process of Web development, because the Class file, that is, the bytecode, must be loaded into the memory at the same time as the running process, when upgrading, the server must be stopped to realize the code upgrade. New code can be injected into memory for use only after restarting
