The data that reception is come from Internet Transmission, and described data are carried out to protocol analysis, business logic processing, generation key assignments and access cache interface, after finishing service logical process, the data of returning are carried out to agreement assembling;
According to the access of cache interface, the region buffer memory of cache partitions Divide File is conducted interviews;
Wherein, the described NIO framework of supporting according to XML file configuration, has realized Socket and HTTP according to described framework; Reception, from the network request of client, sends response data to client, and the data of transmission are added to decoding, comprising:
The NIO framework of supporting according to XML file configuration;
Receive user's request, according to the port of user's access, distinguishing is HTTP or Socket;
Corresponding callback method according to different agreement call request data imports described request data into corresponding callback method in the mode of parameter simultaneously, calling data response method, and send the response data that described data response method is passed back;
Utilize filter mechanism to add decoding to described request data and described response data;
The data that described reception is come from Internet Transmission, and described data are carried out to protocol analysis, business logic processing, generation key assignments and access cache interface, after finishing service logical process, the data of returning are carried out to agreement assembling, comprising:
User's request msg is resolved with the structure of custom protocol;
Protocol number in custom protocol after resolving is carried out to agreement division, and distribute in corresponding map processing logic method, then carry out corresponding logical process according to concrete request msg;
Generate buffer memory key assignments, obtain cache set interface handle, call described handle acquiring cache interface method, described buffer memory key assignments is imported into simultaneously, analyze described buffer memory key assignments whether in effective range;
As in effective range, return to corresponding cache interface object, data cached by described cache interface object acquisition;
If described buffer memory key assignments is not in effective range or obtain data cached failure, accesses third party's data-interface and obtain data;
The data of returning are assembled and returned with the structure of custom protocol;
Describedly according to the access of cache interface, the region buffer memory of cache partitions Divide File is conducted interviews and is comprised:
Allocating cache partitioned file, the mode by buffer memory key assignments with scope is configured in partitioned file;
Receive cache interface request, according to cache partitions configuration, access corresponding caching server, obtain data;
Start timed task, the data in buffer memory are backuped in database, then by database timed backup;
Restoring data is in the caching server list of appointment in batches;
Access third party interface, generate data cached, according to cache partitions configuration, by deposit data in corresponding caching server.
