springboot實現簡單的定時任務?

 1.pom.xml所需依賴

pom.xml

<!-- spring security -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-security</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-quartz</artifactId>
		</dependency>

 2.定時任務作用那塊？

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;


@DisallowConcurrentExecution
@Slf4j
public class ToolQuartz extends QuartzJobBean{
	
	@Autowired
	private UserService userService;

	@Override
	protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
		log.debug("定時任務啓動");
		try {
			//定時調用的方法
			userService.deleteUserinfo(1);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.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;


@Configuration
public class QuartzConfig {
	 @Bean
	    public JobDetail uploadTaskDetail() {
	        return JobBuilder.newJob(ToolQuartz.class).withIdentity("ToolQuartz").storeDurably().build();
	    }

	    @Bean
	    public Trigger uploadTaskTrigger() {
	        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule("0/5 * * * * ?");
	        return TriggerBuilder.newTrigger().forJob(uploadTaskDetail())
	                .withIdentity("ToolQuartz")
	                .withSchedule(scheduleBuilder)
	                .build();
	    }

}

3.啓動類  沒有添加@EnableScheduling註解也可以,具體原因還沒了解

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;

@SpringBootApplication
//@EnableAsync
//@EnableScheduling
@MapperScan("org.asyware.expressway.mapper") // 啓動時掃描的mapper
@RestController

public class ExpresswayApplication {

	public static void main(String[] args) {
		SpringApplication.run(ExpresswayApplication.class, args);
	}
	
	@GetMapping("/test")
	public String test() {
		return "ok";
	}

}

就很簡單的這幾步，就可以了。
