xxl-job 分布式任务调度平台使用，图文版

一，前言

今天公司要升级job平台，需要把以前的调度任务全部平移到新的job平台中，

所以学习了解一下job平台的使用，方便以后回顾。

二，操作

1，拉取代码，启动任务调度平台

gitee地址：https://gitee.com/aimmuselisa/xxl-job.git

注意修改自己的数据库信息，同时执行sql，sql位置 xxl-job\doc\db\tables_xxl_job.sql

直接启动入口类 ：XxlJobExecutorApplication

访问连接：http://localhost:8090/xxl-job-admin/jobgroup

初始账户密码：admin/123456

tips：job项目和我的项目是连接的同一个数据库哦哦哦哦😊

2，引入依赖，添加配置（针对自己需要引入job的项目）

pom引入依赖

        <dependency>
            <groupId>com.xuxueli</groupId>
            <artifactId>xxl-job-core</artifactId>
            <version>2.4.0</version>
        </dependency>

application.properties 添加配置

### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
### 需要和job-admin服务地址保持一致
xxl.job.admin.addresses=http://127.0.0.1:8090/xxl-job-admin

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

### xxl-job executor appname，需要和平台执行器保持一致
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

添加配置类

@Configuration
public class XxlJobConfig {
   
    private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);

    @Value("${xxl.job.admin.addresses}")
    private String adminAddresses;

    @Value("${xxl.job.accessToken}")
    private String accessToken;

    @Value("${xxl.job.executor.appname}")
    private String appname;

    @Value("${xxl.job.executor.address}")
    private String address;

    @Value("${xxl.job.executor.ip}")
    private String ip;

    @Value("${xxl.job.executor.port}")
    private int port;

    @Value("${xxl.job.executor.logpath}")
    private String logPath;

    @Value("${xxl.job.executor.logretentiondays}")
    private int logRetentionDays;


    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
   
        logger.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppname(appname);
        xxlJobSpringExecutor.setAddress(address);
        xxlJobSpringExecutor.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }
 }

写个demo监听器

@Component
public class demoJobHandler {
   

    private static Logger logger = LoggerFactory.getLogger(demoJobHandler.class);
    /**
     * 1、简单任务示例（Bean模式）
     */
    @XxlJob("demoJobHandler")
    public void demoJobHandler() throws Exception {
   
        XxlJobHelper.log("XXL-JOB, Hello World.");

        for (int i = 0; i < 5; i++) {
   
            XxlJobHelper.log("beat at:" + i);
            TimeUnit.SECONDS.sleep(2);
        }
    }
}

再次刷新平台

-----------------------------------------------------有以下情况就算引入成功

a，执行器有机器注册地址

b，有测试任务

c，任务执行成功日志
