Prior to the configuration management, only when the app starts to read the contents of git, and then as long as the app does not restart, git file modification, the application is not aware of, even if restarting config server.Like the Hello World app in the previous unit (Spring Cloud Starter Tutorial (ii): Configuration Management), manually update the contents of the configuration file config-client-dev

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
