### 简介 ###

Quartz是OpenSymphony开源组织在Job scheduling领域又一个开源项目，它可以与J2EE与J2SE应用程序相结合也可以单独使用。Quartz可以用来创建简单或为运行十个，百个，甚至是好几万个Jobs这样复杂的程序。Jobs可以做成标准的Java组件或 EJBs。Quartz的最新版本为Quartz 2.3.0。

## 实现 ##

新建springboot项目并添加相关Web依赖

新建job包

在job包下新建MyJib.java

package com.example.demo.job;
    
    import java.text.SimpleDateFormat;
    import java.util.Date;
    
    import org.springframework.scheduling.annotation.Scheduled;
    import org.springframework.stereotype.Component;
    @Component
    public class MyJob {
     
     @Scheduled(fixedRate=1000)
     public void run() {
      System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
     }
    
    }

关键点：

类上加注解@Component

方法上加@Scheduled，其中fixedRate=1000表示1秒执行1次

在springboot项目启动类中开启定时任务支持

@EnableScheduling

添加Job包使能扫描到

package com.example.demo;
    
    import java.util.List;
    
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.autoconfigure.http.HttpMessageConverters;
    import org.springframework.context.annotation.Bean;
    import org.springframework.http.converter.HttpMessageConverter;
    import org.springframework.scheduling.annotation.EnableScheduling;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
    
    import com.alibaba.fastjson.serializer.SerializerFeature;
    import com.alibaba.fastjson.support.config.FastJsonConfig;
    import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
    @MapperScan("com.example.demo.mapper")
    @EnableScheduling
    @SpringBootApplication(scanBasePackages= {"com.example.demo.controller","com.example.demo.service","com.example.demo.interceptor","com.example.demo.handler","com.example.demo.job"})
    public class HelloSpringBootApplication //extends WebMvcConfigurerAdapter{
    {
    
    
     public static void main(String[] args) {
      
      SpringApplication.run(HelloSpringBootApplication.class, args);
     }
    
    }
