SpringAop-based hot plug exception capture method and device

Abstract

The invention provides a SpringAop-based hot plug exception capture method and device. The method comprises the following steps of: matching a method in a first program project by using an executive expression through a tangent plane configuration class defined based on SpringAop; and when it is detected that the target method in the first program project is abnormal, creating a processing class after the target method is abnormal in the second program project, and performing compression to obtain a compressed file; uploading the compressed file to a server, and storing the class name of the compressed file, the storage position information of the compressed file in the server and the executive expression of the target method into a preset database; loading and storing the position information through the virtual machine, and instantiating the class name of the compressed file to obtain an instantiated object; and associating the instantiated object with the target method based on theexecutive expression of the target method so as to intercept the target method. Thus, the compressed file is remotely obtained and dynamically injected into the first program project, and dynamic exception capture and processing can be achieved so as to improve the exception processing capacity of the program.

Description

technical field [0001] The present invention relates to the technical field of program anomaly detection, in particular to a SpringAop-based hot swap anomaly capture method and device. Background technique [0002] Abnormalities may occur during the operation of computer programs. When an unpredictable exception occurs in the program, it will cause the program to be interrupted. A common exception capture method is to hard-code the code and perform try / catch exception capture where an exception may occur. However, when the abnormality is caught in this hard-coded way, the program will be interrupted. After the abnormality of the program is repaired by repairing the code, the version needs to be released, which will consume more time and cost. Contents of the invention [0003] In order to improve the above problems, the present invention provides a SpringAop-based method and device for hot-swap exception capture. [0004] The first aspect of the embodiments of the prese...
