SuperMap iServer service component development framework

As the figure indicates, SuperMap iServer is built by develop framework of tri-level structure system.

• Realizes the GIS function dealing by the GIS computing core or third party GIS service, e.g., UGCMapProvider realizes the GIS function of map operation by the UGO core.

• Module of Component level: devided by the GIS function, package Provider modules, e.g., Map Component calls the Map Provider module in Provider level, and provides serial GIS functions of the map operation

• Servlet or Interface in the Interface level: built by different service mode, Servlet or Interface, publish Component module as various kinds of service, e.g.: Map Component as REST style map service, Data Component as WFS service.

Modules of the 3 levels connect by the unified interface, this ensures the conversation availability between modules. Create relationship between modules dynamically for each module in the 3 levels by the configuration files (describing the module calling relationship between each level) and dependence injection tech (calling dynamically by the relationship between each level). All kinds of GIS services provided by SuperMap iServer is built by the module's combination and affection between the 3 levels.

Multi-level service structure of SuperMap iServer provides great basic framework for the domain space information service expansion of users. By the self business demanding, user could develop function module matches with own business feature on any level of the SuperMap iServer service system. Domain space information service module and the built-in module within SuperMap iServer have the same status, SuperMap iServer could published it finally as the domain space information service.
