【XXL-JOB】2-1.执行器项目的搭建--执行定时任务（java）

场景

1.项目中已搭建好XXL-job调度中心,(安装请移步)
2.SpringBoot项目（新搭建好的项目，有需要执行的定时任务）

步骤

Step1: pom.xml 引入依赖

            <dependency>
                <groupId>com.xuxueli</groupId>
                <artifactId>xxl-job-core</artifactId>
                <version>2.3.1</version>
            </dependency>

Step2: yaml添加配置 application.yml

addresses: http://ip:port/xxl-job-admin #xxljob调度中心部署
appname: weather #xxljob配置的执行器名称
port: 19900 #xxljob配置的端口号，默认为9999

xxl:
  job:
    admin:
      addresses: http://ip:port/xxl-job-admin  #xxljob调度中心部署 例如：http://127.0.0.1:8080/xxl-job-admin
    executor:
      address:
      appname: weather #xxljob配置的执行器名称，
      ip:             #执行器IP，默认为空表示自动获取IP
      port: 19900 #xxljob配置的端口号，默认为9999
      logpath: /data/xxl-job/jobhandler  #执行器运行日志文件存储磁盘路径
      logretentiondays: -1  #调度中心日志表数据保存天数，过期日志自动清理；限制大于等于7时生效，否则, 如-1，关闭自动清理功能
    accessToken: default_token #调度中心通讯TOKEN [选填]：非空时启用

Step3: 引入配置类 XxlJobConfig.java

import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * xxl-job config
 *
 * @author xuxueli 2017-04-28
 */
@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;
    }

}

Step4:方法上加注解即可 @XxlJob("weatherNow")

编写定时任务服务类，如天气服务 WeatherJob.java

注意同项目中@XxlJob中的命名不能重复

@Component
@Slf4j
public class WeatherJob {

    /**
     * 1、定时更新当前天气(10min)
     */
    @XxlJob("weatherNow")
    public void weatherNow() throws Exception {
        log.info(">>>>>>>>>>>>>>>>>>>>>>>>XxlJob: get weatherNow .");
        List<WeatherChinaCity> cityList = weatherChinaCityService.getUpdateCity();
        for (WeatherChinaCity c : cityList) {
            weatherNowService.updateNow(c.getId());
        }

    }
