Abstract

The invention discloses a data query method and device based on configuration information, and relates to the technical field of computers. A specific embodiment of the method comprises the followingsteps: receiving a query request of an application system based on a unified service framework, wherein the query request comprises a query parameter and an index identifier ID uniquely pointing to atarget database corresponding to the application system; obtaining configuration information according to the index ID, wherein the configuration information comprises a query statement template; according to the query parameters and the query statement template, dynamically generating executable query statements; and obtaining a query result according to the executable query statement. Accordingto the embodiment, a unified query mode can be provided for multiple systems, the number of code writing is effectively reduced, the readability of executable query statements is improved, and the data query efficiency and the development and production efficiency are greatly improved. In addition, the embodiment supports high availability, high concurrency and flexible expansion at the same time,and can adapt to more service scenes and fields.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data query method and device based on configuration information. Background technique [0002] When querying data in the prior art, query statements are often written directly in the code. This data query method has at least the following problems: [0003] 1) Different systems often correspond to different databases, and the data structures of different databases are not necessarily the same. Therefore, when querying data for different systems, it is necessary to write query statements in the code separately, which is highly repetitive, requires a large amount of code writing, and makes management and maintenance of query statements difficult, which greatly increases the difficulty and cycle of project development; [0004] 2) The code readability of the query statement is low, and it takes a lot of time to understand and locate the query statement; [0005] 3) Every time...
