@ConditionalOnExpression 根据表达式选择性加载 @ConditionalOnProperty 根据配置选择性加载

#消费者总开关，0关1开
mq.cumsumer.enabled=1
#rocketmq消费者开关，true开启，false关闭
rocketmq.comsumer.enabled=false
#rabbitmq消费者开关，true开启，false关闭
rabbitmq.comsumer.enabled=true
#消费者选择
mq.comsumer=rabbitmq

//布尔值和数字 @Component @RabbitListener(queues = "monitorDataQueue") @ConditionalOnExpression("${mq.cumsumer.enabled:0}==1&&${rabbitmq.comsumer.enabled:false}")

//字符串 @Component @RabbitListener(queues = "monitorDataQueue") @ConditionalOnExpression("'${mq.comsumer}'.equals('rabbitmq')")

// 直接使用boolean 的校验 // spring.batch.job.enabled = true

@ConditionalOnProperty(prefix = "spring.batch.job", name = "enabled", havingValue = "true", matchIfMissing = true)
