（37） How bee uses different data source instances at the same time

 Bee How to use different data source instances at the same time ??

In addition to configuring the tables and tables corresponding to different data sources javabean Outside the package rules of entities ( If in bee.properties To configure ),

stay Bee V1.11 It also provides direct designation of data sources .

For example , ds1 Yes, it is configured as mysql Data source .  And then through :

mysqlSuidRich.setDataSourceName("ds1");

	public static SuidRich getMysqlSuidRich() {
		SuidRich mysqlSuidRich=BF.getSuidRich();
//		 Data sources can use Java Mode configuration , You can also use xml Mode configuration 
//		mysqlSuidRich.setDataSourceName("mysqlDsName");
		mysqlSuidRich.setDataSourceName("ds1");  // This instance is on InitDsUtil.initDS(); use java Setting mode 
		return mysqlSuidRich;
	}

The complete example is as follows :
