Consider defining a bean of type 'javax.sql.DataSource' in your configuration.

To define a bean of type 'javax.sql.DataSource' in your configuration, you can follow these steps:

1. Import the necessary packages:

   import javax.sql.DataSource;
   import org.springframework.context.annotation.Bean;
   import org.springframework.jdbc.datasource.DriverManagerDataSource;

2. Configure the DataSource bean by providing the necessary properties such as driver class, URL, username, and password:

   @Bean
   public DataSource dataSource() {
       DriverManagerDataSource dataSource = new DriverManagerDataSource();
       dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
       dataSource.setUrl("jdbc:mysql://localhost:3306/mydatabase");
       dataSource.setUsername("username");
       dataSource.setPassword("password");
       return dataSource;
   }

3. Customize the properties based on your database configuration. In this example, I used MySQL database with the driver class `com.mysql.cj.jdbc.Driver` and URL `jdbc:mysql://localhost:3306/mydatabase`. Replace these values with your own database details.

4. Make sure to update the username and password with the appropriate credentials for your database.

5. Once you have defined the DataSource bean, you can use it in other components of your application by autowiring it or by using the `@Resource` annotation.

Note: The above example assumes you are using Spring Framework for dependency injection and configuration. Make sure you have the necessary dependencies in your project's build file (e.g., Maven or Gradle) to support Spring JDBC.
