Springboot Turn off Automatic Configuration

springboot is automatically configured via @ EnableAutoConfiguration under @ SpringBootApplication, which saves developers a lot of time, but there may be some unnecessary configuration. What should I do if I want to turn off one of the configurations?

Use the exclude parameter under @ SpringBootApplication.

For example:

1. Turn off Redis automatic configuration

@SpringBootApplication(exclude={RedisAutoConfiguration.class  })

2. SpringBoot automatically configures the database by default

You can also operate in pringBootApplication annotations if the business does not need it:

@SpringBootApplication(exclude = {
DataSourceAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class,
HibernateJpaAutoConfiguration.class})

Note: Multiple configurations can be separated by commas

Turn on and off the automatic task configuration process

1. Requirements

You can dynamically control the timing task of springboot with @ Scheduled according to the switch configured by yourself

2. Solutions

1. Delete @ EnableScheduling for the startup class

2. Condition judgment using condition

public class SchedulerCondition implements Condition {
    @Override
    public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
        return Boolean.valueOf(context.getEnvironment().getProperty("com.myapp.config.scheduler.enabled")); // Is yml Value       
    }
}

3. Assemble new timed tasks to IOC

 @Configuration
 public class Scheduler {
    @Conditional(SchedulerCondition.class)
    @Bean(name = TaskManagementConfigUtils.SCHEDULED_ANNOTATION_PROCESSOR_BEAN_NAME)
    @Role(BeanDefinition.ROLE_INFRASTRUCTURE)
    public ScheduledAnnotationBeanPostProcessor scheduledAnnotationProcessor() {
        return new ScheduledAnnotationBeanPostProcessor();
    }
}
