=== Disabling Specific Auto-configuration Classes
If you find that specific auto-configuration classes that you do not want are being applied, you can use the exclude attribute of `@EnableAutoConfiguration` to disable them, as shown in the following example:
If you find that specific auto-configuration classes that you do not want are being applied, you can use the exclude attribute of `@SpringBootApplication` to disable them, as shown in the following example:
[source,java,indent=0]
----
import org.springframework.boot.autoconfigure.*;
import org.springframework.boot.autoconfigure.jdbc.*;
import org.springframework.context.annotation.*;
@Configuration
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class MyConfiguration {
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class MyApplication {
}
----
If the class is not on the classpath, you can use the `excludeName` attribute of the annotation and specify the fully qualified name instead.
If you prefer to use `@EnableAutoConfiguration` rather than `@SpringBootApplication`, `exclude` and `excludeName` are also available.
Finally, you can also control the list of auto-configuration classes to exclude by using the `spring.autoconfigure.exclude` property.
TIP: You can define exclusions both at the annotation level and by using the property.
