spring cloud microservices tutorial

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 Conf

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
