Xxl-job使用

一、docker部署xxl-job

1. 下载镜像images

docker pull xuxueli/xxl-job-admin:2.3.0

2. 创建容器
   （1）配置数据库地址，用户名，密码
   （2）容器中xxl-job-admin默认是8080端口，使用服务器8888端口建立映射
   （3）设置服务器开启时启动

docker run -e PARAMS="--spring.datasource.url=jdbc:mysql://192.168.56.10:3306/xxl_job?Unicode=true&characterEncoding=UTF-8 \
--spring.datasource.username=root \
--spring.datasource.password=root" \
-p 8888:8080 -v /tmp:/data/applogs \
--name xxl-job-admin --restart=always  -d xuxueli/xxl-job-admin:2.3.0

3. 使用服务器映射端口登录

http://192.168.56.10:8888/xxl-job-admin/

二、使用

1. maven

		<dependency>
            <groupId>com.xuxueligroupId>
            <artifactId>xxl-job-coreartifactId>
            <version>2.3.0version>
        dependency>

2. 执行器配置

/**
 * 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;
    }

    /**
     * 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：
     *          
     *             org.springframework.cloud
     *             spring-cloud-commons
     *             ${version}
     *         
     *
     *      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();
     */


}

3. application.yml配置

（1）调度中心地址
（2）执行器名称
（3）执行器端口

xxl.job.admin.addresses=http://192.168.56.10:8888/xxl-job-admin
xxl.job.executor.appname=xxl-job-executor-sample
xxl.job.executor.port=8999

4. 后端代码

@Component
public class RunXxlJob {

    @XxlJob(value = "xxx")
    public void runJob(){
      ......
    }

}
