Design And Implementation Of Ship Performance Prediction Integrated System Based On J2EE Framework

In CSSRC(702 Institude) the existing applications belonging to the department are isolated, most of the key information are being closed in the systems which are independent of each other.In order that it is possible to interact between different information systems and ship-designers are able to consider most of the water kinetic factors in the peroid of designing concept and increase the efficiency and quality of work,we need to establish a distributed and networked ship performance prediction integrated system which balances the kuaisu,caozong,naibo,and other performance indicators.J2EE is the standard platform for developping the distributed enterprise applications. J2EE is able to provide powerful technological support for complex enterprise applications. But it is so complex that if developers are lack of enough skills or experience the failure will happen. We are fortunate that the open source community have emerged in a number of excellent open-source framework, they are a simplified edition of J2EE and provided a powerful support to our development, with them we can develop high-quality efficiency system.Now the better open-source framework for j2ee view layer, business Logic layer and data persistence layer is Struts,Spring and Hibernate.In this paper, we analysis the advantages and principle of Struts, Spring and Hibernate framework, and then introduce how to integrate Struts, Spring and Hibernate and build a lightweight, short development cycle, low development cost, loosely coupled, easily expanded J2EE development platform and how to use the SSH to develop the ship performance prediction integrated system.At the same time we tried to use the Domain-Driven Design (DDD) to make modeling in order to replace the traditional method of modeling based on database, and then use Hibernate(a excellent ORM framework)to achieve the persistent of domain modeling object.In this way, designers and development staffs are able to focus on domain object without paying too much attention to database operation.
