Abstract

The invention discloses a method and a device for achieving data transmission by utilizing POJO. The method comprises extension of POJO, wherein the extension of the POJO specifically comprises: setting unified plain old java objects (UniPOJO) that can be inherited by business objects and UniPOJOList that can be dispatched. The method further comprises: collection of change information of data, namely transferring and saving the change information of data in the same state to a group of business POJO instance objects, and encapsulating each group of business POJO instance objects into the UniPOJOList, wherein each group of business POJO inherit the UniPOJO. The change information of data is transmitted to the background program through the UniPOJOList. In the embodiment of the invention, the problem that the POJO can not support and bear the additional information such as original value before change in the prior art is resolved.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a method and a device for extending a simple traditional Java object (POJO) to realize supporting additional information. Background technique [0002] The object-oriented development method is the mainstream development method in the enterprise-level application development, and the relational database is the mainstream data storage system used in the enterprise-level application environment. Objects and relational data are two manifestations of business entities. Business entities are represented as objects in memory and as relational data in the database. There are associations and inheritance relationships between objects in memory, but in a database, the relational data model cannot directly express many-to-many associations and inheritance relationships. [0003] Many lightweight object-relational mapping (ORM, Object Relational Mapping) frameworks such as...
