Problems solved by technology

[0004] In the process of implementing the above invention, the inventor found that in the process of deserializing a JSON string into a Java object in the prior art, among the multiple fields contained in the JSON string, there are at least two fields corresponding to the data content When the original data type is a numerical type, it is necessary to determine the data content with the highest data precision among multiple data contents, and then deserialize all the data contents whose original data type is a numerical type in this JSON string according to the numerical type corresponding to this data content Therefore, deserializing a JSON string into a Java object through the existing technology will cause the deserialized Java object to The data accuracy often cannot meet the actual needs

Abstract

The invention discloses a deserialization method and device, and relates to the technical field of data processing, which can solve the problem that in the process of deserializing a JSON string intoa Java object, when the data content of the original data type being numberical type in the JSON string is deserialized according to the numeric type of the data content with the highest data precision, the data precision of some data content in the obtained deserialized Java object changes in the prior art. The method of the invention comprises the following steps of: receiving a JSON string; parsing the JSON string to obtain the parsing result; determining an original data type of a data content corresponding to each field name, and judging whether the data content contains at least two datacontents of which the original data type is a numerical type; If so, the JSON string is converted to a Java object according to the original data type corresponding to each data content. The invention is suitable for application in the process of deserializing a JSON string into a Java object.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a deserialization method and device. Background technique [0002] With the increasing development of Internet technology, information interaction between different application systems has become more frequent. Since different programming languages ​​are used in the development of different application systems, when information is exchanged between different application systems, it is necessary to convert the object to be transmitted into a common data format before data transmission. Since the JSON (JavaScript Object Notation, JavaScript Object Notation) structure is a lightweight data exchange format completely independent of the programming language, there are great advantages in using the JSON structure as the transmission carrier for data transmission between different application systems. [0003] At present, in the process of information interaction between two di...
