Role-based access control policy has been widely applied to various access control system design. In order to improve the flexibility of authorization check design and convenience of management, this paper uses the principle of dynamic proxy design to optimize this process, also provide a method which is Spring AOP based of transaction management for program running. The role-create method proposed can configure the users authority flexible. The improved design concept can achieve the basic requirements if role-based access control policies, and improve the efficiency of project development and security of application system maximum.

Ajax technology has been widely applied in a variety of Web development. It takes full advantage of existing technical standards to achieve updating the contents of the page without refreshing the entire page. In this paper, Ajax asynchronous mode enhances the credibility of user experience, optimizes the transmission between the browser and the server and reduces unnecessary data transferring back and forth and bandwidth usage. Using XML packaging method achieved Ajaxs efficient operation of bulk data and made the application of Ajax more extensive. Practice shows that Ajax technology based on XML packaging can provides a flexible and fast bulk data processing function in Web development.
