Method and system for rapidly deploying and loading java applications in cloud environment

Abstract

The embodiment of the present invention discloses a method and system for rapidly deploying and loading Java applications in a cloud environment, wherein the method includes: the application deployment client device determines the shared JAR library of the cloud platform according to the local Java application shared class library JAR directory Incremental shared JAR files that do not exist, package the incremental shared JAR files, private JAR files, and shared JAR file identification files into a Java application deployment package, and send the Java application deployment package to the cloud application deployer; the cloud application deployer starts from Java Extract the incremental shared JAR file from the application deployment package, store the incremental shared JAR file in the shared JAR library, remove the incremental shared JAR file in the Java application deployment package and send it to the application container; The deployment package loads the Java application. The embodiments of the present invention can improve Java application deployment efficiency and reduce memory consumption of application containers.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a method and system for rapidly deploying and loading Java applications in a cloud environment. Background technique [0002] Java is an object-oriented programming language that can write cross-platform application software. To deploy a Java application in a cloud environment, all the resources and classes of the Java application in the local environment need to be packaged into an application deployment package, which is uploaded to the application container on the cloud platform through the Internet to run. [0003] Java applications generally use a large number of third-party class libraries or frameworks (such as Struts, Spring, Hibernate), and the class library (Java Archive, JAR) files required by the application must be packaged into the application deployment package, resulting in the size of the application deployment package as high as Tens of megabytes or even hundreds...

AI Technical Summary

Problems solved by technology

[0006] 1. The cost of Java application cloud migration is high

When a Java application needs to be migrated and deployed to the cloud platform, it is necessary to ensure that the class library version of the Java application is consistent with the application container. If the Java application uses a class library version inconsistent with the application container, the Java application must be modified and restarted. Compilation, which increases the migration cost of Java applications;

[0007] 2. It is difficult to upgrade and maintain the class library

[0008] 3. The Java application deployment package is still huge

[0011] 2. The application instance of each Java application deployed to the application container needs to be fully loaded, and the class library that the Java application depends on will also be loaded into the memory. Repeatedly loading the same class library for different application instances increases the memory and memory capacity of the application container. Input / Output (I / O) Overhead
