Public interface UserService {public

     map<string, object> findbyid (int id);  
     
     Public list<map<string, Object>> querylist ();

The reason why there is a service interface, because both producers and consumers to use the interface, the interface as a single MAVEN Java project can be placed into the private library to the production side and the consumer end of the same use.
