1.3 Startup Class Add Annotations

2. git Server Combined with Config

Using git server, you can build gitlab server by yourself, or use github, open source China git, Aliyun Git

2.1 Create Configuration Center Project on GitHub

Login git to create configuration center repository

Create dev nodes.

Description: Distinguish production and test environments by branches.
master: production environment configuration
dev: Test environment configuration

2.2 Configuration Center Configuration

2.2.1 Production Environment Configuration

Production environment: master branch configuration
