前言

公司要求使用springblade框架开发，需要用到多数据源的场景

1、 application-dev.yml配置文件

#数据源配置
spring:
  datasource:
    dynamic:
      primary: master
      strict: false #严格匹配数据源,默认false. true未匹配到指定数据源时抛异常,false使用默认数据源
      datasource:
        master:
          url: jdbc:mysql://192.1.1.0:3306/data_18_ind_poscal?useSSL=false&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true&allowPublicKeyRetrieval=true
          username: root
          password: root
          driver-class-name: com.mysql.cj.jdbc.Driver
        doris: 
          url: jdbc:mysql://192.168.101.120:9030/ads
          username: root
          password: root
          driver-class-name: com.mysql.jdbc.Driver

2、service层

service层用@DS("doris") 来指定doris数据源。

3、修改 spring.datasource.dynamic.enabled

全局搜 spring.datasource.dynamic.enabled 将其值改为 true
修改配置

备注

不修改 spring.datasource.dynamic.enabled为true 会报以下错 :

If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (the profiles dev are currently active).
