// Get all instances of the MyService class MapIn the first example, we retrieve all instances of a custom service class. In the second example, we retrieve all instances of a JDBC transaction manager interface. And in the third example, we retrieve all instances of the `DataSource` class from the Spring JDBC package. The `getBeansOfType` method is part of the `org.springframework.context` package library.services = context.getBeansOfType(MyService.class); // Get all instances of the TransactionManager interface Map txManagers = context.getBeansOfType(TransactionManager.class); // Get all instances of the DataSource class from the Spring JDBC package Map dataSources = context.getBeansOfType(DataSource.class);
