[英]Data source inject to Crud Repository spring boot
Is there any way to inject or set up data source to Crud Repository? 有什么方法可以将数据源注入或设置到Crud存储库吗? I need one repository and multiple database with same schema.
我需要一个具有相同架构的存储库和多个数据库。 I tried to make hash map with database name and data source and use something like that https://spring.io/blog/2007/01/23/dynamic-datasource-routing/ but it doesn't work
我试图用数据库名称和数据源制作哈希映射,并使用类似https://spring.io/blog/2007/01/23/dynamic-datasource-routing/的方法,但是它不起作用
This solved my problem 这解决了我的问题
@Component
public class RoutingDataSource extends AbstractRoutingDataSource {
@Autowired
private DatabaseMap databaseMap;
@Override
public void afterPropertiesSet() {
setTargetDataSources(databaseMap.getSourcesMap());
setDefaultTargetDataSource(databaseMap.getSourcesMap().get("DEFAULT"));
super.afterPropertiesSet();
}
@Override
protected Object determineCurrentLookupKey() {
return DatabaseContextHolder.getDatabaseType();
}
}
@Configuration
public class DatabaseLoader {
@Bean
public DatabaseMap databaseMap() {
//init databases using DataSourceBuilder
return databaseMap;
}
}
I change context same way as here https://spring.io/blog/2007/01/23/dynamic-datasource-routing/ 我使用与此处相同的方式更改上下文https://spring.io/blog/2007/01/23/dynamic-datasource-routing/
