there is a user in the A_user: Auser,b_user has a user buser, so you no matter which user login, CAS will first check a_user, if the user name password is correct, then pass, if the A_user failed to verify, then CAS will check b_ User, username and password are correct even if passed, this time is not correct, even if the login verification failed. Summary: The above is a simple configuration of the database query data validation process, in the application process of CAs is very common, for

This article describes the C + + Single example mode and its related application methods, share for everyone to reference. The specific methods are analyzed as follows: Defined: A class has and has only one instance, and provides a global access point to access it.Points:1, the class can only have one instance;2. This instance must be created by itself;3. This instance must be provided to the whole system

Topic: Design a class that can only generate an instance of the class. (1) Solution one: only applicable to single-threaded environment Since a requirement can only generate one instance, we must set the constructor as a private function to prevent others from creating the instance. We can define a static instance and create that instance when needed. public class singleton1{ private Singleton1 () { } private static Singleton1 instance =

, performs the detection on line 10th, and does not perform the build if Singleton has been generated. To prevent thread B from saving a copy of the singleton value, you can define singleton as volatile so that each time you check the singleton, you need to reread the singleton value, and then write it again after each assignment. As for thread-safe single case mode, you can use the enumeration class direct

Label:This is a question I encountered in the PHP interview, the singleton pattern literally is a certain class only one instance, the benefits are still very large, such as database connection, we only need to instantiate once, do not need to go to new each time, this greatly reduces the cost of resources. The Singleton class has at least the following three common elements: Must have a constructor and must be marked private.has a static member variable that holds an instance of the class.Have
