And objects with the same attribute exist in different classes of the namespace, at the moment, all attribute values of the source object can be directly copied to the target object, so that the workload of developers is reduced.

In order that those skilled in the art will better understand the disclosure, the following detailed description is given with reference to the accompanying drawings.
Method embodiment
A copy method provided by the present application is described below by way of an example.
Technical terms that need to be referred to in this document will be described in detail.
Front end: the front end is a foreground part of the website and runs on browsers such as a PC (personal computer) end and a mobile end to display webpages browsed by a user.
A database: a database is a "warehouse that organizes, stores, and manages data according to a data structure," which is an organized, sharable, uniformly managed collection of large amounts of data that is stored in a computer for a long period of time.
Class and object: classes and objects are a composite term for two computer languages carried by a computer. An object is an abstraction of an objective thing, and a class is an abstraction of an object. A class is an abstract data type. The relationship between them is that an object is an instance of a class, which is a template for the object.
Deep copying: a new object and array are created, and the 'values' (all elements of the array) of the properties of the original object are copied over, being 'values' rather than 'references'.
Note: the annotation, also called callout, is a type of reference data that is added from java 5. Annotations are essentially special tags in the code by which processes can be compiled, class loaded, and executed at runtime.
Referring to fig. 1, which is a flowchart of a copying method provided in an embodiment of the present application, as shown in fig. 1, the method may include:
s101: a source object and a target object are obtained.
In this step, a source object and a target object transmitted by a front end are obtained, where the source object includes an attribute name and an attribute value corresponding to the source object, the target object includes an attribute name and an attribute value corresponding to the target object, the attribute value corresponding to the target object is null, and correspondingly, the attribute value corresponding to the source object is not null, and the front end may be a PC end, which is not specifically limited herein.
As an implementation manner, after the source object and the target object are acquired, the source object and the target object are stored in corresponding databases, and operations may be performed on data in the databases, where the operations may include querying data, adding data, modifying data, deleting data, and the like. The database may be a Mysql database, and the database may also be a SqlServer database, which is not limited herein.
S102: and in response to the fact that the attribute names corresponding to the source object and the target object are the same, copying the attribute value corresponding to the source object into the attribute value corresponding to the target object.
In this step, after the source object and the target object are obtained, it is determined whether the attribute names corresponding to the source object and the target object are the same, and if the attribute names corresponding to the source object and the target object are the same, the attribute value corresponding to the source object is copied to the attribute value corresponding to the target object. And if the attribute names respectively corresponding to the source object and the target object are different, acquiring a next target object until the attribute names respectively corresponding to the next target object and the source object are the same. Or, the target object is reserved, and the next source object is obtained until the attribute names corresponding to the next source object and the target object are the same. It should also be noted that the source object and the target object are in different classes.
The following description is made with reference to specific examples. In this example, the category in which the source object is located is a, the attribute name of the source object is C, and the attribute value of the source object is 1; the category of the target object is B, the attribute name of the target object is C, and the attribute value of the target object is 0. When the attribute names corresponding to the source object and the target object are the same (for example, when both are C), the attribute value "1" of the source object is copied to the attribute value of the target object, and at this time, the attribute value of the target object is changed from "0" to "1".
In response to that the attribute names respectively corresponding to the source object and the target object are the same, the attribute type corresponding to the target object or the attribute type corresponding to the source object is also determined, where the attribute types include a basic data type, a collection type, and a reference type. It should be noted that the attribute type corresponding to the target object is the same as the attribute type corresponding to the source object. That is, after the attribute type corresponding to the target object is determined, the attribute type corresponding to the source object can be determined.
It can be understood that, when the attribute type corresponding to the target object is the basic data type, and at this time, the attribute values corresponding to the source object and the target object are one, the attribute value corresponding to the source object is copied to the attribute value corresponding to the target object; when the attribute type corresponding to the target object is an aggregate type, and at the moment, the attribute values corresponding to the source object and the target object are multiple, copying each attribute value in the attribute values of the source object aggregate into the attribute value corresponding to the target object; when the attribute type corresponding to the target object is a reference type, at this time, the attribute values corresponding to the source object and the target object are multiple and nested layer by layer, and the attribute values corresponding to the source object are copied into the attribute values corresponding to the target object layer by layer until the reference relationship is finished.
As another implementation manner, after a source object and a target object are obtained, firstly, an annotation of an attribute corresponding to the target object and an annotation of an attribute corresponding to the source object are obtained, where the annotations are aliases corresponding to the attributes, and if the annotations of the target object are the same as the annotations of the source object, then an attribute type corresponding to the target object or an attribute type corresponding to the source object is determined, and finally, different copying methods are used according to different types of the target object or different types of the source object, so as to copy the attribute value corresponding to the source object to the attribute value corresponding to the target object.
In addition, the application is applied to a back-end server, and the copy proposed in the application can be understood as a deep copy, so that the deep copy can be freely realized among different object types through the copy mode, and the software development efficiency is improved.
Therefore, the alternative scheme mainly explains how to extend the financial credit system based on the public welfare field. Specifically, in this alternative, a source object and a target object are obtained, where the source object includes an attribute name and an attribute value corresponding to the source object, the target object includes an attribute name and an attribute value corresponding to the target object, and the attribute value corresponding to the target object is null; and in response to the fact that the attribute names corresponding to the source object and the target object are the same, copying the attribute value corresponding to the source object into the attribute value corresponding to the target object.
In summary, in this embodiment, under the condition that the attribute names corresponding to the source object and the target object are the same, the attribute value in the source object is copied to the attribute value in the target object, so as to improve the software development efficiency, further reduce the workload of software development, achieve the optimization of codes, and implement free copying of the attribute value between different object types.
