The invention provides a posting / subscribing
system for adding
message queue models and a working method of the posting / subscribing
system. The
system comprises a distributed message-oriented
middleware server-side cluster, a
client-side cluster and a distributed coordinate
server cluster. Service nodes in the message-oriented
middleware server-side cluster are composed of corresponding modules of an original posting / subscribing system, and the function of the message-oriented
middleware server-side cluster is the same as the information transferring relation; a
client side is simultaneously provided with a calling interface of a posting / subscribing model and a calling interface of a
message queue model which are used for achieving the purpose that a user can select and use the two different message transferring models directly without transforming the bottom layer middleware, so that a coordinate
service module and a
message processing module are additionally arranged on the
client side based on an original framework. The system supports the posting / subscribing message transferring model and the
message queue message transferring model simultaneously and guarantees that the availability, flexibility and other performance of the two models are all within the acceptable range, and the problem that it is difficult to transform the bottom layer message transferring model for the user is better solved.
