Abstract

The invention discloses an application program upgrading method, system and device and a computer storage medium, which are applied to a tomcat server to obtain a new version file of a target application program. The method comprises the steps of generating a target class file corresponding to the new version file; re-creating a target class loader corresponding to the target class file; and afterthe current running process of the target application program is finished or the old version file corresponding to the target application program is cleared, loading the target class file based on the target class loader so as to complete upgrading of the target application program. In the present application, a target class file corresponding to the new version file is generated, and a target class loader corresponding to the target class file is re-created. After the current running process of the target application program is finished or the old version file corresponding to the target application program is cleared, the target class file is loaded based on the target class loader, so that the target class loader is used for replacing the old version loader for application upgrading, and the upgrading risk can be reduced.

Description

technical field [0001] The present application relates to the technical field of data processing, and more specifically, relates to an application program upgrading method, system, device and computer storage medium. Background technique [0002] The tomcat server is a free and open source web application server. It is a lightweight application server. It is widely used in small and medium-sized systems and occasions where there are not many concurrent access users. It is the first choice for developing and debugging JSP programs. The tomcat server can deploy multiple web applications. For the deployment of running applications, the tomcat server has two release methods, one is hot deployment, and the entire project is redeployed. The server will clear the cache and release memory. One is hot loading. The cache is not cleared and the memory is not released. [0003] However, if the tomcat server uses the hot deployment method to release the application, the instance object ...
