若依微服务代码生成支持SQLServer操作（184）
一、后端
1.导入依赖
<!-- sqlserver-->
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
</dependency>
2.yml配置配置数据源
datasource:
# 主库数据源
master:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/test?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&useSSL=false&serverTimezone=GMT%2b8
username:
password:
# 从库数据源
sqlserver:
driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver
url: jdbc:sqlserver://127.0.0.1:1433;databasename=DEMO
username:
password:

二、数据库
哪个数据需要支持代码生成,对应的数据库,也要增加这两个表。
增加以上代码与配置之后,想用哪个数据库的实现,就用@Primary标注切换即可。
注意：sqlserver版本不同可能会存在语法不一致问题，本文使用2012R2
