Method for flexibly generating GraphQL interface based on multi-source data

The invention discloses a method for flexibly generating a GraphQL interface based on multi-source data. The method comprises the steps of heterogeneous data source management, metadata information extraction, interface configuration management, interface configuration injection and refreshing, service release and namespace management. Information of a heterogeneous data source is input by a business personnel, and metadata information of a related table is collected by utilizing a metadata information extraction function according to the information of the data source; through management of interface configuration, a description mode of a data model adopts links of uniformly penetrating source data acquisition, data conversion, data open permission limitation, data interface generation, data interface release, client data acquisition and the like; then the configuration information is packaged and the configuration information is injected into a dynamic language background service in combination with the sta
