项目创建与统一依赖管理

1. 项目结构

sca-study

|- pom.xml

|- user-center

|- src

|- pom.xml

|- content-center

|- src

|- pom.xml

2. 版本使用列表

3. 根项目配置

4. 创建微服务项目

分别创建user-center和content-center两个微服务项目，并为微服务指定端口和名称

user-center的application.yml配置

server:
  port: 18082

spring:
  application:
    # 指定微服务名称，微服务间调用时需要使用
    name: user-center

content-center的application.yml配置

server:
  port: 18081

spring:
  application:
    # 指定微服务名称，微服务间调用时需要使用
    name: content-center
