Research And Application Of Single Sign-on Technology In Enterprise Application Integration Based On J2EE

With the extensive application of information systems in the enterprise, the enterprise will establish information systems to meet their own needs, and in the development, deployment, these systems do not give much thought to systems integration and information sharing. Authentication, when the increase in the application system, the user logs on each system should be carried out so many times, log on to the system in the offing, and reduce work efficiency. Many companies are considering the integration of its own portal, but due to various application development platform, framework, as well as store data authentication methods are likely to be different.To solve this problem, single sign-on technology, single sign-on for enterprise applications to provide a unified set of authentication mechanisms and access to the entrance, and the establishment of a unified user management system management information about the user.This paper first introduces the principle of CAS-based single sign-on solution and J2EE-based Struts2, Spring and Hibernate framework, according to the actual needs of enterprise application integration, unified user authorization using LDAP-based way to store user information and provide Web service interface to facilitate other applications call. Finally, to achieve a unified user management platform with a single sign-on system.The main innovation of this paper proposed a unified authorized Web service interface for applications to call user information. Enterprise applications integration provides a possible solution is universal.
