Spring Cloud Config provides service-side and client support for configuration features in distributed systems. For applications of different environments its service side provides a centralized configuration management approach. And it applies not only to spring applications, but also to programs developed in other languages (which is important).Environmental requirements

※ After the DALSTON.SR2 version, the encryption is not normal, if you must use this feature, you need to downgrade to SR1 or Camden SR7.1, first need to create a config-server project, as a configuration Center server, used to connect with git, svn or the local warehouse, get the configuration file from the warehouseThe ①config-server project Pom file needs to add the following dependencies:Dependency>Group
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

Brief introduction:
Spring Cloud provides developers with tools to quickly build distributed systems, including configuration management, service discovery, circuit breakers, routing, micro-proxies, event busses, global locks, decision-making campaigns, distributed sessions, and more. It runs in a simple environment and can run on a developer's computer.
Tools:
JDK8
apache-maven-3.5.2
In the previous article we described a service how to read a file from the configuration center, configuration Center How to read the configuration file from remote git, when a lot of service instances, all the files 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:

Brief introductionIn the Distributed file system, 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 service (that is, local) and also in a

Any entry in the Config row is also a scope. For example, you write this:
CONFIG + + warn_on
You will get a scope called "warn_on". This will make it easy to modify the configuration in your project without losing all of the customizations that might be require

Brief introductionIn a real-world project environment, we do not store confidential text such as passwords in plaintext in the configuration file in case of theft. Spring Cloud Config provides an encryption method for encrypting plaintext text encrypted into ciphertext stored in a configuration file. Spring Cloud Config provides two types of encryption and decryption, one is symmetric encryption, and the ot
