Study And Implementation Of A Message Middleware On A Data Exchange Platform

With the extensive applications development of information technology in a various of industry, information systems have been established in almost of every area such as enter-prises, affair office departments, institutions, and hospital organizations and etc.. However, the information sharing among enterprises, affair office departments or hospital organizations is very difficulty, thereby information island has been produced one by one due to the dif-ferences produced by adopting between technologies and definition of data structure. In order to solve the technique problem of the data exchange platform, there is an urgent need for an effi-cient and reliable message oriented middleware software system which is used to construct an ex-change platform. The author designed and implemented a message oriented middleware system which is very suitable for the data exchange platform.The main research and development work of this paper is described below:1) The current research status of the distributed system is analyzed and summarized. Specifi-cally, the current research status、 principal and implementation mechanism of the message ori-ented middleware system is analyzed and summarized.2) The network application framework Netty with the style of asynchronous event-driven software architecture is analyzed, and the mechanism of the framework is analyzed in deep detail.3) Then a message oriented middleware system is designed and implemented based on the Netty framework. A message queue model is implemented in this system, and it supports three type of message including command message, data message, and file message. For the file mes-sage, this paper adopt the strategy of transferring file contents and messages in different channel.4) The message transfer protocol and file content transfer protocol for the message oriented middleware system is designed and implemented. The monitor system which is responsible for monitoring the runtime status of this system is also designed based on WebSocket protocol.Deployment and Test show that the message oriented middleware software system which is proposed in this paper can meet the application demand of the data exchange platform and is suit-able for constructing the data exchange platform of enterprises.
