persistence consists of 3 parts:(1) Exchange persistence, specifying durable + 1 at the time of declaration(2) Queue persistence, specify durable when declaring = 1(3) Message persistence, specifying Delivery_mode = 2 on delivery (1 non-persistent) if both Exchange and queue are persisted, the binding between them is persistent. If there is a persistence between Exchange and queue, a non-persisted, binding is not allowed. 3.6.1 Upgrade, instructions

In many cases, we need to do something at a given time, such as a system backup between 2:00-3:00. At this point, we need to use the task scheduling instructions.Specifies that the system completes the specified task during the specified event by using the "task Scheduling directives" setting:> crontab–e//Edit Task scheduling instructions> crontab–l//view task scheduling instructions Copyright NOTICE: This

The ANGULARJS directive is used to extend HTML. These are the special attributes from the ng-prefix first. We will discuss the following instructions: Ng-app-This instruction initiates a ANGULARJS application. Ng-init-This instruction initializes the application data. Ng-model-this directive defines the model that the variable is used in Angularjs. Ng-repeat-the directive will repeat the HTML element for each item in the collection. Ng-app direct

The crontab command is common in UNIX and Linux operating systems and is used to set periodically executed instructions. This command reads the instruction from the standard input device and stores it in a "crontab" file for later reading and execution. Typically, crontab stored instructions are activated by the daemon. Crond often runs in the background and checks every minute to see if there are scheduled

SUBSTRING (parameter) is a way to intercept strings in JavaThere are two ways to pass the argumentOne is public String substring (int beginindex)Returns a new string that is a substring of this string. The substring starts at the character at the specified index until the end of the string.The other is public String substring (int beginindex, int endIndex)Returns a new string that is a substring of this string. The substring starts at the specified beginindex until the character at index EndInde
