轻量级分布式任务调度框架，核心目标是开发迅速、学习简单、轻量级、易扩展

XXL-JOB的使用

参考地址

首先从GitHub上面将项目clone下来

GitHub地址：https://github.com/xuxueli/xxl-job

Gitee地址：https://gitee.com/xuxueli0323/xxl-job

通过IDEA打开

运行sql文件

打开xxl-job-admin模块，在application.properties中进行后台的配置

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/xxl_job?Unicode=true&characterEncoding=UTF-8&serverTimezone=UTC

注意在数据库地址哪里加上时区属性，否则乱码

主页面

启动XxlJobAdminApplication类，访问http://localhost:8080/xxl-job-admin 默认账户admn，密码123456

任务代码

定位到springboot模块下的jobhandler层

编写一个自己的定时任务

@Component
public class MyJobHandler {
    @XxlJob("testMyJob")
    public void testMyJob(){
        System.out.println("testGood!!xxl-job-executor-sample");
    }
}

在任务管理里面新增任务

可以选择单机串行或者丢弃后续调度

jobHandler填入

@XxlJob("testMyJob") 字符串的名字

点击启动即可

项目中集成

在项目中引入依赖

<dependency>
  <groupId>com.xuxueli</groupId>
  <artifactId>xxl-job-core</artifactId>
  <version>2.0.1</version>
</dependency>

将xxl-job-executor-sample-springboot这个模块下的XxlJobConfig复制一份到项目中，然后将相关配置设置好即可

配置文件

    @Bean

        return xxlJobSpringExecutor;
    }

    /**
     * 针对多网卡、容器内部署等情况，可借助 "spring-cloud-commons" 提供的 "InetUtils" 组件灵活定制注册IP；
     *
     *      1、引入依赖：
     *          <dependency>
     *             <groupId>org.springframework.cloud</groupId>
     *             <artifactId>spring-cloud-commons</artifactId>

     *         </dependency>
     *
     *      2、配置文件，或者容器启动变量
     *          spring.cloud.inetutils.preferred-networks: 'xxx.xxx.xxx.'
     *
     *      3、获取IP
     *          String ip_ = inetUtils.findFirstNonLoopbackHostInfo().getIpAddress();
     */

pro配置文件

# web port
server.port=8085
# no web
#spring.main.web-environment=false

# log config
logging.config=classpath:logback.xml


### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8080/xxl-job-admin

### xxl-job, access token
xxl.job.accessToken=default_token

### xxl-job executor appname
xxl.job.executor.appname=xxl-job-executor-sample
### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
xxl.job.executor.address=
### xxl-job executor server-info
xxl.job.executor.ip=
xxl.job.executor.port=9999
### xxl-job executor log-path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30

重要配置
private String adminAddresses;

private String accessToken;

private int port;

setAppname 设置执行器名字

@Autowired
private InetUtils inetUtils;

打包成jar放在服务器即可,不需要放在tomcat下

定义脚本

flow-star-job.jar名字自定义

nohup java -jar flow-star-job.jar &

sql文件注意

集成到项目中,不要直接运行sql,需要创建sql需要的几个表即可
