Spring java database configuration

import javax.annotation.Resource;
import javax.sql.DataSource;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.jdbc.core.JdbcTemplate;

@Configuration
// spring config that loads the properties file
@ImportResource(value = { "classpath:db.xml" })
public class DBConfig {
 @Resource
 private DataSource oracleDataSource;

 @Bean
 public JdbcTemplate jdbcTemplate() {
  return new JdbcTemplate(oracleDataSource);
 }
}

db.xml contains database configuration and looks like
