Problems solved by technology

[0005] The existing technology can only modify the parameters, so as to achieve the purpose of adjusting the program by modifying the parameters. The flexibility is poor, and it can only switch between several preset situations. For the situations other than the preset, it cannot be processed, and only the code can be modified. to redeploy the program

Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0040] The names involved in the present invention are explained below:

[0041] Classloader refers to: the class loader, specifically, the virtual machine loads the data describing the class from the class bytecode file to the memory, and performs inspection, conversion, analysis and initialization on the data, and finally forms a Java that can be directly used by the virtual machine Type, this is the class loading mechanism of the virtual machine.

[0042] The Spring container refers to: an instance of a class that implements the ApplicationContext interface. In o...

Abstract

The invention discloses a program modification method and device, and relates to the technical field of mobile interconnection. The method comprises the steps: receiving a program modification request; calling a code loading interface according to the program modification request; loading pre-stored code data from a server based on the code loading interface; and according to pre-stored code data, modifying original code data in the Spring container of the to-be-modified program. The behavior of dynamically modifying the program can be completed without redeployment, and the flexibility is high.

Description

technical field [0001] The invention relates to the technical field of mobile internet, in particular to a method and device for modifying a program. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In the software system developed by java programs, once the software development is completed and deployed online, the behavior of the program is determined, and the execution logic of the program can only be adjusted through preset parameters. Once an error occurs in the program, the only way to modify the code is to And redeploy to fix it. [0004] The inventor finds that the prior art has at least the following problems: [0005] The existing technology can only modify the parameters, so as to achieve the purpose of adjusting the program by modifying the parameters. The flexib...
