We can also configure Spring Data JPA by using XML. We can do
this by adding the
repositories
namespace element of Spring
Data JPA to our application context configuration file.
Configuring the data source bean
We will start the configuration of the data source bean by adding a
dataSource()
method to the
ApplicationContext
class and annotating this method with the
@Bean
annotation. The implementation of this method is as follows:
1.
Create an instance of the
BoneCPDataSource
class.
2.
Set the database connection details.
3.
Return the created object.
The configuration of the data source bean is given as follows:
@Bean
public DataSource dataSource() {
BoneCPDataSource ds = new BoneCPDataSource();
ds.setDriverClass(env.getRequiredProperty("db.driver"));
ds.setJdbcUrl(env.getRequiredProperty("db.url"));
ds.setUsername(env.getRequiredProperty("db.username"));
ds.setPassword(env.getRequiredProperty("db.password"));
return ds;
}
