Therefore, in the embodiment, when the monitoring module 202 listens to the field data operation, that is, when the field data changes, the determining module 205 determines whether the changed field is marked with a self. Define the entity class field for the annotation. If the changed field is an entity class field marked with a custom annotation, the obtaining module 203 acquires a data change record monitored by the monitoring module 202. If the changed field is not an entity class field marked with a custom annotation, the obtaining module 203 ignores the change information of the field data, that is, does not record the change of the data. The application server 2 reduces the system running pressure of the server by judging whether the changed field is marked with a custom annotation entity class field, ignoring the unimportant field data change information.
通过上述程序模块205，本申请所提出的自动记录字段变化*** 200，还能够当监听到数据发生变化时，判断所述数据是否是标注有自定义注解的实体类数据，若发生变化的字段为标注有自定义注解的实体类字段时，获取数据变化记录。若发生变化的字段不是标注有自定义注解的实体类字段时，忽略该字段数据的变化信息，即不记录所述数据的变化，以减轻服务器的运行压力。Through the above-mentioned program module 205, the automatic record field change system 200 proposed by the present application can also determine whether the data is entity class data marked with a custom annotation when the data changes are monitored, and if the changed field is Get a data change record when an entity class field with a custom annotation is marked. If the changed field is not an entity class field marked with a custom annotation, the change information of the data of the field is ignored, that is, the change of the data is not recorded, so as to alleviate the running pressure of the server.
此外，本申请还提出一种自动记录字段变化方法。In addition, the present application also proposes an automatic record field change method.
