springboot实现简单的定时任务?

 1.pom.xml所需依赖

pom.xmlorg.springframework.bootspring-boot-starter-securityorg.springframework.bootspring-boot-starter-quartz

 2.定时任务作用那块&＃xff1f;

package org.asyware.expressway.quartz;import org.asyware.expressway.service.UserService;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.QuartzJobBean;import lombok.extern.slf4j.Slf4j;&＃64;DisallowConcurrentExecution
&＃64;Slf4j
public class ToolQuartz extends QuartzJobBean{&＃64;Autowiredprivate UserService userService;&＃64;Overrideprotected void executeInternal(JobExecutionContext context) throws JobExecutionException {log.debug("定时任务启动");try {//定时调用的方法userService.deleteUserinfo(1);} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}}


package org.asyware.expressway.config;import org.asyware.expressway.quartz.ToolQuartz;
import org.quartz.CronScheduleBuilder;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;&＃64;Configuration
public class QuartzConfig {&＃64;Beanpublic JobDetail uploadTaskDetail() {return JobBuilder.newJob(ToolQuartz.class).withIdentity("ToolQuartz").storeDurably().build();}&＃64;Beanpublic Trigger uploadTaskTrigger() {CronScheduleBuilder scheduleBuilder &＃61; CronScheduleBuilder.cronSchedule("0/5 * * * * ?");return TriggerBuilder.newTrigger().forJob(uploadTaskDetail()).withIdentity("ToolQuartz").withSchedule(scheduleBuilder).build();}}


3.启动类  没有添加&＃64;EnableScheduling注解也可以,具体原因还没了解

package org.asyware.expressway;import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;&＃64;SpringBootApplication
//&＃64;EnableAsync
//&＃64;EnableScheduling
&＃64;MapperScan("org.asyware.expressway.mapper") // 启动时扫描的mapper
&＃64;RestControllerpublic class ExpresswayApplication {public static void main(String[] args) {SpringApplication.run(ExpresswayApplication.class, args);}&＃64;GetMapping("/test")public String test() {return "ok";}}


就很简单的这几步&＃xff0c;就可以了。
