Based on the event-Rule mechanism, you can view all activities and status changes in the process.Activities are always accompanied by events. process logic and business logic are abstracted as processes.Rules. when an event occurs, process rules are matched based on the system environment and status.A new event or execution of a new activity. In this model, the event mechanism is a business table in the form of rules.The display method is associated w

ASPECTJ is a tangent-oriented framework that extends the Java language. ASPECTJ defines the AOP syntax, so it has a dedicated compiler to generate class files that conform to the Java Byte encoding specification.There are two main ways to use AOP in Springboot: annotation interception and Method rule interception, as shown in the following article.First, create a simple springboot 2.03 project, add AOP dependencies Dependency > groupId >org.sprin

　　Delete Port forwarding rules Describe Deletes a specified port forwarding rule. The port forwarding rules are independent of the ECS lifecycle. That is, when you delete a port forwarding rule, ECS is not stopped, and the associated port forwarding rules are not deleted when you stop or even destroy ECS. Each port forwarding rule has a state, value of availa

Thoughts determine existence and consciousness determine vision. Do the same in China. If we only look at the market with a single eye, we may only see it. If we look at the Chinese culture, Chinese character, and Chinese history, maybe we will see another different world, find different ways, and even create different miracles.

I have implented the idataerrorinfo interface on the baseentity class. thiis interface provides the functionality to offer custom error information that a user interface can bind. controls like the datagridview automatautomatautomatically detect this interface and provide error icons along with descriptions about the error. hand in hand with this, I have also added the ability to attach validation rules to the Entity objects. there are some built-in validators (stringmaxlength, stringrequired, n

I paid attention to this five-minute rule when I was investigating "> SSD last year. Today I found another revision of this article (to commemorate Jim Gray). I can briefly introduce this topic, it is helpful for architects to measure I/O capabilities, evaluate the cache, and select hardware. In 1987, Jim Gray and Gianfranco putzolu published the "five-minute rule". In short, if a record is frequently acc

There is an old debate about where to store applications Program Business logic: whether it is in the application's business logic layer or in the database layer. The absolute supporter of the application logic layer proposed that the only purpose of the database is to save data for use by the application. Those who advocate the use of databases to store business rules insist that business rules are best stored in databases because data is also stored there and rules are easier to run. In my opi

JavaScript: Rule mode of Design PatternIntroduction The rule mode defines the algorithm family and encapsulates them separately so that they can replace each other. This mode prevents algorithm changes from affecting the customers who use the algorithm.Body Before understanding the rule mode, let's take an example. Generally, if we want to verify the validity of
