Enterprise service bus and message processing method thereof

A message processing method of ESB, comprising:

• receiving messages each having at least one service request;
• sorting the received messages according to predefined rules;
• and
• processing service requests from a predefined number of the sorted messages, wherein processing the service requests comprises:
• invoke work procedures corresponding to the service requests, wherein the work procedures are pre-stored in the ESB, and each of the work procedures is corresponding to one of the service requests and defines specific procedures and rules for invoking one or more application services;
• generating access requests according to the work procedures;
• and
• invoking corresponding application services according to the access requests.

A computer program product, comprising a non-transitory computer readable medium embodying a computer readable program for operation on a computer to implement an enterprise service bus (ESB), said program comprising:

• a message receiving unit, including multiple message receiving channels, each message receiving channel for receiving messages each having at least one service request;
• a message queuing unit for receiving messages from the multiple message receiving channels and for sorting the messages according to predefined rules;
• a processing-thread-group for receiving a predefined number of sorted messages from the message queuing unit;
• and
• a request processing unit for:
• acquiring service requests from messages from the processing-thread-group;
• invoking work procedures corresponding to the service requests, wherein the work procedures are pre-stored in the ESB, and each of the work procedures is corresponding to one of the service requests and defines specific procedures and rules for invoking one or more application services;
• generating access requests according to the work procedures;
• and
• invoking corresponding application services according to the access requests.

A computer program product, comprising a non-transitory computer readable medium embodying a computer readable program for operation on a computer to implement a message processing method of ESB, said program comprising instructions that cause the computer to perform the steps of:

• receiving messages each having at least one service request;
• sorting the received messages according to predefined rules;
• and
• processing service requests from a predefined number of the sorted messages, wherein processing the service requests comprises:
• invoking work procedures corresponding to the service requests, wherein the work procedures are pre-stored in the ESB, and each of the work procedures is corresponding to one of the service requests and defines specific procedures and rules for invoking one or more application services;
• generating access requests according to the work procedures;
• and
• invoking corresponding application services according to the access requests.
