配置文件數(shù)據(jù)源讀取

通過springboot的Envioment和Binder對(duì)象進(jìn)行讀取，無需手動(dòng)聲明DataSource的Bean

yml數(shù)據(jù)源配置格式如下:

spring:
 datasource:
 master:
  type: com.alibaba.druid.pool.DruidDataSource
  driverClassName: com.mysql.cj.jdbc.Driver
  url: jdbc:mysql://localhost:3306/main?
useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai
  username: root
  password: 11111
 cluster:
  - key: db1
  type: com.alibaba.druid.pool.DruidDataSource
  driverClassName: com.mysql.cj.jdbc.Driver
  url: jdbc:mysql://localhost:3306/haopanframetest_db1?
useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai
  username: root
  password: 11111
  - key: db2
  type: com.alibaba.druid.pool.DruidDataSource
  driverClassName: com.mysql.cj.jdbc.Driver
  url: jdbc:mysql://localhost:3306/haopanframetest_db2?
useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai
