<!-- quartz --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-quartz</artifactId> </dependency>
- 添加配置类
@Configuration public class SchedulerConfig implements SchedulerFactoryBeanCustomizer { @Override public void customize(SchedulerFactoryBean schedulerFactoryBean) { schedulerFactoryBean.setStartupDelay(2); schedulerFactoryBean.setAutoStartup(true); schedulerFactoryBean.setOverwriteExistingJobs(true); } }
- application.yml 配置
项目使用的是 Druid
