Today, I will talk to you about how to turn off the automatic configuration of Springboot, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

Springboot turns off automatic configuration

Springboot implements automatic configuration through @ 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 these configurations?

You can use the exclude parameter under @ SpringBootApplication.

Examples are as follows:

1. Turn off Redis automatic configuration @ SpringBootApplication (exclude= {RedisAutoConfiguration.class}) 2. SpringBoot automatically configures the database by default

If the business does not need it, you can also operate in the pringBootApplication annotations:

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

Note: commas can be used to separate multiple configurations.

Turn on and off automatic task configuration process 1. Demand

You can dynamically control the scheduled tasks with @ Scheduled in springboot according to the switch configured by yourself.

two。 Solution

1. Delete @ EnableScheduling of the startup class

two。 Using condition to judge the 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 the yml value}}

3. Assemble new scheduled 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 ();}} after reading the above, do you have any further understanding of how Springboot turns off automatic configuration?
