Spring 5 Design Patterns

Configuring a data source using a JDBC driver

Using a JDBC driver to configure a data-source bean is the simplest data source in Spring. The three data source classes provided by Spring are as follows:

• DriverManagerDataSource: It always creates a new connection for every connection request
• SimpleDriverDataSource: It is similar to the DriverManagerDataSource except that it works with the JDBC driver directly
• SingleConnectionDataSource: It returns the same connection for every connection request, but it is not a pooled data source

Let's see the following code for configuring a data source bean using the DriverManagerDataSource class of Spring in your application:

In Java-based configuration, the code is as follows:
