Method and device for handling class conflict problem

Abstract

The invention discloses a method and device for processing class conflict problems, and displays the cause and configuration of the class conflict problem to users in a visual manner, wherein the method includes: when the class conflict problem occurs in the process of loading classes , configure the loading mechanism according to the class conflict problem; if the loading mechanism is the parent loading package mechanism, when the application server AS and the WEB module both contain class loading resources corresponding to the class, use the parent class loader to load the class contained in the AS Load resources to load; if the loading mechanism is the WEB loading package mechanism, when both the AS and WEB modules contain class loading resources, use the WEB class loader to load the class loading resources contained in the WEB module; When the class loading resource is contained in the AS, the parent class loader is used to load the class loading resource contained in the AS. Through the above-mentioned technical features disclosed in the present application, the class conflict problem can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of class loading, and more specifically, to a method and device for processing class conflicts. Background technique [0002] Major manufacturers of middleware, such as Tomcat and Weblogic, have different strategies for dealing with the class loading problem of WEB modules, and different strategies determine whether they can avoid class loading problems to the greatest extent. [0003] The inventors found that Tomcat has few strategies for dealing with class loading problems of WEB modules, and does not provide a non-delegated strategy; Weblogic's strategies for class loading problems of WEB modules are complicated and not very transparent. Therefore, when class conflicts occur during class loading, it is usually necessary for professional staff to resolve the class conflicts based on personal experience, resulting in high labor costs, and often due to the experience limitations of professional staff...

Problems solved by technology

[0003] The inventor found that Tomcat has very few strategies for dealing with class loading problems of WEB modules, and does not provide a non-delegated strategy; Weblogic's strategies for class loading problems of WEB modules are complicated and not very transparent

Therefore, when a class conflict occurs during class loading, it is usually necessary for professional staff to solve the class conflict problem based on personal experience, which results in high labor costs, and often occurs due to the experience of professional staff. Effectively resolve class conflict issues

That is, there is no technical solution that can effectively deal with the class conflict problem in the prior art
