針對地鐵應(yīng)急演練、信號故障監(jiān)控、輔助故障處理等應(yīng)用具有系統(tǒng)實時性要求較高、
數(shù)據(jù)傳輸量較大等特點，利用Ajax模式和MVC架構(gòu)相結(jié)合的方法設(shè)計并實現(xiàn)了一種采用
Ajax + Struts + Hibernate框架的地鐵應(yīng)急演練與輔助決策系統(tǒng)。該系統(tǒng)結(jié)合了Ajax技術(shù)快速異步響應(yīng)和MVC架構(gòu)成熟穩(wěn)定等的特點。實驗表明：采用該架構(gòu)能有效地降低客戶端與服務(wù)器的通訊量，顯著提高系統(tǒng)性能。

Abstract: Metro emergency drilling, signal fault monitoring and decision-making support system has a higher real-time requirements and a greater volume of data transmission contrast with other system. This paper presents a method to solve all these problems based on the integration of Ajax and MVC model. The System combines the technology of Ajax, Struts and Hibernate. The experiment indicated that in the method proposed, communication between browser and server is reduced and the delay of pages refresh has become much lower than before. This framework improves system performance significantly.
