Why do I use CAS.
Original: CAs in Java JAYXU no Czech pathPrior to JDK 5, the Java language was guaranteed to be synchronized by the Synchronized keyword, which would result in a lockThe lock mechanism has the following issues:(1) Under the multi-thread competition, the locking and release lock will lead to more context switching and scheduling delay, causing performance problems.(2) A thread holding a lock causes all other threads that require this lock to hang.(3) I

Summary
I recently studied the SSO (Single Sign on: Single Sign-On) principle.So I want to use CAS (implementation framework based on the SSO principle) to deepen my understanding and refer to the specific code implementation. So I have published this series of articles.Start with
Start the article, the Great God Detour.One. Service-Side BuildingThe server version number I used is: Cas-server-3.4.11-release.zip. After unpacking, rename the \cas-server-3.4.11-release\cas-server-3.4.11\modules\cas-server-webapp-3.4.11.war file to Cas.war, Place the Tomcat\webapps folder under Tomcat, and then star
CAS (Central Authentication Service) is a single sign-on system developed by Yale University.

Yes. CAS systems have been applied to various universities, such as Yale University, University of California, Cambridge University, and Hong Kong University of Science and Technology.

Previous "SSO single Point Series" (1): CAS environment construction introduces the establishment of CAS's simplest environment, and an example to explain one of the most basic uses of CAs. Today is mainly about how to personalize the CAS login page.I. StartCAS is the default login interface, you can see that this interface is definitely not directly used in the

CAS Lock-Free algorithmThere are a number of implementations to implement a lock-free-free non-blocking algorithm, where CAS (compare and exchange, Compare and swap) is a well-known lock-free algorithm. CAs, CPU instructions, in most processor architectures, including IA32, space, are CAS directives, the semantics of
First look at some data, mentioned the CAS operation is a problem, that is, before CAs A into B and back to A,cas or can set a successful, began very puzzling, how possible, a changed back to a should be able to CAS success ah, why not succeed?
So I went to check some information, which mentioned two situations:The fi

There is always a single sign on the wood to hear. But I do not know the principle of it; Single Sign-On (SSO) is a popular business integration scheme, and users can access mutual trust application system only once. Today I am based on CAs to achieve single sign-on, hoping to give everyone inspiration. 2. precautions

At present, we have encountered a very headache. At present, the company has multiple application systems developed using C #, Java, C ++, C, VB, and other languages, to solve the login problem between multiple application systems, we plan to use SSO to solve the login problem and achieve single-point login. As long as we log on to any of the systems, we can access the resources and services of other systems, these application systems use B/S, and C/S. for B/S applications,
