Bytecode object copying method and device, equipment and storage medium

Abstract

The invention relates to a byte code object copying method, device and equipment and a storage medium, and the method comprises the steps: constructing a mapper factory which is used for configuring,registering and generating a function for executing mapping; setting a conversion class, wherein the conversion class is used for performing type conversion; setting a mapping class, wherein the mapping class is used for customizing object mapping; based on the mapper factory, the conversion class and the mapping class, when it is judged that byte code mapping is generated in advance through classannotation, completing mapping on a pre-loaded object through the first field annotation and the second field annotation so as to generate byte codes and cache the byte codes. Automatic scanning assembly is adopted, the effect of complex mapping simple application is achieved in cooperation with annotation, the problem that the starting time is too long due to full-object assembly is avoided, resources are saved, and performance, safety and stability are improved; the coding efficiency is improved, the cost is reduced, and the realization is more convenient.

Description

technical field [0001] The present invention relates to the field of encoding technology, in particular to a bytecode object copy method, device, equipment and storage medium. Background technique [0002] In Java applications, it is often necessary to convert objects into different forms to adapt to different APIs (Application Programming Interface, application programming interface), or to transfer objects in different business layers, and objects of different layers have different formats, so , you need to write mapping code to convert the property value in the object from one type to another. [0003] In related technologies, there are three methods of object conversion: first, hard coding; in this method, a large number of boilerplate codes need to be manually created and consume a lot of time, which greatly reduces development efficiency and prolongs the development cycle. Second, the reflection method has poor performance and execution efficiency. Third, the bytecod...
