Modularized JAVA application software online updating system and method

Abstract

The invention discloses a modularized JAVA application software online updating system. The system comprises a software resource information mining sub-system and a software dynamic updating sub-system, wherein the software resource information mining sub-system comprises a system file monitor, a source code loading analyzer, a system class analyzer, a class dependence relationship generator, a tree or directed graph dependence relationship generator and a module division generator; the software dynamic updating sub-system comprises an interface, a general agent unit, a module agent unit and a management platform; the general agent unit comprises a plant module, a time chop stamp module and a registration center; the module agent unit comprises an object manager, a class loader and a module describer. The system can realize service loading without restarting the service system. The invention also discloses a modularized JAVA application software online updating method. By adopting thesystem and the method, service loading is realized under a condition of not restarting the system.

Description

technical field [0001] The invention relates to an online update system and method for modular JAVA application software. Background technique [0002] With the continuous development of the information society, it has become very common for a software system to be continuously updated with changes in requirements. Therefore, software update has become very important for a software system. Only continuous software update Updates can adapt to the ever-changing user needs of users. [0003] In order to adapt to the ease of software update, excellent design patterns are constantly being invested in software design, providing great support for software update design, and new technologies and architectures are constantly emerging to realize the ease of use of software update. For example, aspect-oriented programming and service-oriented architecture, these design patterns, technologies, and architectures can achieve code independence and easy scalability, so as to achieve the pu...

Problems solved by technology

[0003] In order to adapt to the ease of software update, excellent design patterns are constantly being invested in software design, providing great support for software update design, and new technologies and architectures are constantly emerging to realize the ease of use of software update. For example, aspect-oriented programming and service-oriented architecture, these design patterns, technologies, and architectures can achieve code independence and easy scalability, so as to achieve the purpose of easy software update and expansion, but these technologies only solve the problems in the development stage. software update, but failed to solve the problem of dynamic software update when the system is running

[0004] At present, for a software system that has already been launched, if it is updated, the server must be stopped, and the updated software system must be recompiled and released for deployment, which will inevitably cause the service of the software system to be stagnant for a certain period of time , which will affect the use of users. For business systems with a large number of users, such as air traffic control systems, global financial transaction systems, industrial control systems, network service systems, etc., maintenance is achieved by stopping, updating and restarting and updates would result in unacceptable delays, costs and hazards, and result in substantial economic losses
