Support for multiple data sources use @DataSource annotation to determine which datasource will be use. @DataSource support Repository Class and Method level. If not assigned a @DataSource annotation will use primary datasource.

Hi @hatunet, wasn't this already possible? I was using multiple data source. Will you this time write a documentation?

多数据源功能实现了吗？

shook2012 avatar Feb 22 '19 16:02 shook2012

我看您之前有提交实现多数据源相关功能的代码，后面又删除了。是因为实现的不是你想要的样子？ 之前的是可以做到调用不同方法，使用不同的数据源吧。但@DataSource在类上并不起作用，对吧。

@DataSource定义在子类的方法上时； 执行CrudRepository父接口的方法时，切面获取不到子接口的@Datasource注解？！

如果你有思路 可以给个PR

我重写了MultipleDataSourceAspect，不同的datasource的repository放在不同的包，在MultipleDataSourceAspect根据包路径切面来切换数据源了...这个方案可行，但不算是通用方案。

AOP不是问题，关键是事务
