摘　　要：通过对Hibernate Spatial和JTS的研究,基于SOA体系架构,提出以服务方式,构建松散耦合地图服务的技术方法,实现将空间信息对象化表达及存储到数据库中,最终实现松散耦合地图服务。通过应用上述技术方法体系,结合某部级部门地理信息数据,实现了基于网络通过Flash方式展示地图,集采集、查询、数据备份恢复于一体的应用系统,实现了跨数据库的数据备份及恢复功能,实践表明,这是一个行之有效的方法。Based on the architecture of SOA and researeh on Hibernate Spatial and JTS, this paper proposes constructing a loosely architecture of map service on the basis of Hibernate Spatial in type of service. Under this circumstance decoupling of the database and the service transfer can be implemented. The actual movement case with a loosely coupled spatial data restoration has been established making use of technology developed in this paper. Based on the above technology and method system, combined with the geo-information database of a department, this system fulfilled displaying map through Flash based on the web. An application system integrated with collection gathering, querying and backuping has been set up, accomplished the data backup and restoration between different databases. The practical application shows that the system is reasonable and feasible.
