This section we'll create a service interface based on the example in previous section, Creating a service provider, to build a complete and fully user-defined service interface.

The example in previous section,  Creating a service provider, has completed the following items:

• Implement the service component, service provider, and their configuration.
• The service component uses the dependency injection method of SuperMap iServer to call service providers.
• The service component uses the annotation to confirm its service provider type.
• Publish domain service component by using SuperMap iServer REST.

Here we'll implement a custom service interface "TemperatureServlet" based on Servlet and publish the service component finished in previous section with this interface. Main contents:

• Implementing a service interface
• Refactoring the service component
• Configuring the service
• Publishing the service
