Development on Construction Project Cost System Based on Spring

摘要

Spring is to solve the common problem in many J2EE development, and can replace strong lightweight framework in the EJB technology. Based on Spring development construction project cost system, to improve the competitiveness of building enterprise and information technology services. First of all, based on the Spring framework structure, the Spring MVC request processing process; Then, following the abstract and incremental refinement, the principle of modularity and information hiding, designed by the six main function modules of the system; Finally, using the JDBC method to design the data access, including entity class structure and write two steps to implement the DAO. The research achievements of this paper to solve the key technical problems in the software development process, the actual development process to exert the advantages of Spring, to avoid the shortcomings, in order to improve the software performance.
