Attribute loading method and system

The invention discloses an attribute loading method and system. The method comprises the steps of abstracting the source of an attribute value; executing the second step if the source is a dynamic attribute source; judging whether the attribute value exists locally if the source is a static attribute source, and executing the third step if the attribute value does not exist locally; conducting state checking on an attribute file corresponding to the attribute value regularly, returning to the first step if it is found out that no modification is made after the attribute file is compared with historical records, and executing the third step if it is found out that modification is made after the attribute file is compared with the historical records; conducting conversion on the data type of the attribute file according to a forced agreement; loading the converted attribute file. According to the attribute loading method, convenient configuration of dynamic attributes can be realized without much coding work, and complexity and cost can be reduced on the premise that application convenience is improved. According to the attribute loading method and system, the attribute value can be updated dynamically during operation, static attribute loading can be conducted, and conversion from a dynamic state to a static state can be achieved without code modification.
