The Research On And Design Of Data Exchange Technology Based On The JAVA EE And XML

Logistics has played an important role in modern society in a way that the expeditious and smooth information flow must be guaranteed in order to achieve efficient logistics management. Besides, the differences among logistics businesses with respect to the extent to and means of informatization had led to large quantities of problems over data change among information systems, and also brought into question that the relatively important part of information fails to reach the destination in time when it is transmitted to the data change center. In this thesis, in the context of the analysis to the existing data change system and reference of the previous literatures, a data change model with the XML message format and based on the Java EE is proposed, facing the issues of data change among logistics businesses. In addition, the information flow is effectively controlled by adopting the EJB technology on data change servers. The main innovations and research finding are listed below:1) A data change model is proposed along with the overall design and implementation of it. The model is a hub-and-spoke one, and the data change center of it is the Weblogic server through which clients transmit the data. And Struts2.x, Spring2.x and Hibernate3.x are integrated in order to implement the application system of the model.2) Three main models had been designed, i.e. the data conversion model, the safety components model and the receive/send message data model.3)The sending of messages has been simplified by making use of the Spring-jms technology.4) Information being changed has been packed under the certain size, avoiding sending information too frequently in order to reduce the burden on the system.5) When arriving at the data center, the information is separated in terms of different operations and then repacked with being given a priority, based on which that information is re-sent.6) The reminding function has been designed in the receiver, indicating the extent of urgency of relevant information.
