This is an online tutorial on Spring AOP programming. After reading this article, Spring AOP is no longer difficult to understand. Therefore, I have translated it into Chinese and recommended it to Spring AOP

Of course, you can continue to use the lower version
First, IntroductionIn distributed systems, because of the large number of services, in order to facilitate the unified management of service profiles, real-time updates, so the need for distributed configuration Center components. In spring cloud, there is a distributed Configuration center component, Spring Cloud Config, which enables configuration services to be placed in the memory of the configuration s
Brief introductionSpring Cloud provides a platform for deploying microservices, including components that are common in MicroServices: Configuration Center Services, API gateways, circuit breakers, service registration and discovery, distributed traceability, OAuth2, consumer-driven contracts, and more. We don't have to know what each component does, and as the tutorials go deeper, we're getting to them. The general structure of a distributed service is shown (image from: Spring.io):Using
Brief introductionZuul is the API gateway and filtering component provided by spring Cloud, which provides the following features:
Certification
Filter
Pressure test
Canary test
Dynamic routing
Service Migration
Load Balancing
Safety
Static request Processing
Dynamic traffic Management
In this tutorial, we will use Zuul to forward the web-side request /produ
In the previous article about Zuul, it has been mentioned that the configuration service is used to store the configuration files for each service. It's spring Cloud Config.First, IntroductionIn distributed systems, because of the large number of services, in order to facilitate the unified management of service profiles, real-time updates, so the need for distributed configuration Center components. In spring

It uses spring boot's development convenience to subtly simplify the development of distributed system infrastructures, such as service discovery registration, Configuration center, message bus, load balancer, circuit breakers, data monitoring, and so on, all of which can be started and deployed with
Brief introductionIn micro-service, service registration and discovery play a key role in the management of each sub-service subsystem. As the system expands more and more, and the number of systems split into microservices increases correspondingly, the URL to manage and access these microservices becomes tricky, and if we add a micro-service every new one, manually add its URL address or other communication protocol address to the other place where the microservices are used, This often makes
The previous article described how a service reads a file from the configuration center, how the configuration center reads the configuration file from a remote git, and when the service instance is many, reads the file from the configuration center, you can consider the configuration center as a micro-service, clustering it to achieve high availability, the frame composition is as follows:First, the preparatory workContinue with the project of the previous article, create a Eureka-server projec
Spring Cloud has a pre-processor that decrypts property values locally Environment . It follows the same rules as the Config server, and by encrypt.* having the same external configuration. Therefore, you can use {cipher}* encrypted values in a format that, as long as there is a valid key, will be decrypted before the main application context gets fetched Environment . To use the encryption feature in your application, you need to include
