For a large number of existing legacy systems,an integration framework based on Web service and CAS authentication service technology for legacy systems was put forward. In the application process,the framework can not only maintain the stability of the existing legacy systems,but also solve the problem of the user’s repeated logging in to the system.Using CAS-based authentication for legacy system integration,the system integration will have more safety and convenience,and reduce the maintenance costs as well.It’s also significant to improve the system reliability in enterprise application.
