SpringBoot项目配置多数据源实现查询

一.所需依赖

 
         
            org.springframework.boot
            spring-boot-starter
        

        
            org.springframework.boot
            spring-boot-starter-web
        
        
            org.springframework.boot
            spring-boot-starter-test
        
        
            com.baomidou
            mybatis-plus-boot-starter
        



        
            com.baomidou
            dynamic-datasource-spring-boot-starter
        
        
            com.microsoft.sqlserver
            mssql-jdbc
            9.2.1.jre8
        
  
    org.yaml
    snakeyaml
    1.27

com.microsoft.sqlserver
mssql-jdbc
9.2.1.jre8

新版sqlserver连接所需依赖

---

com.baomidou
dynamic-datasource-spring-boot-starter

多数据源所需依赖

  

二.yml配置

spring:
  datasource:
    dynamic:
      primary: master #设置默认的数据源或者数据源组,默认值即为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: #系统业务库
          driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver
          url: jdbc:sqlserver://127.0.0.1:1434;database=test1;encrypt=false
          username: sa
          password: jly720609
        real_time_database: #实时库
          driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver
          url: jdbc:sqlserver://127.0.0.1:1434;database=test;encrypt=false
          username: sa
          password: jly720609
