部署任务调度中心

jar部署

参考中文教程即可部署

docker部署

部署任务调度中心和Mysql(使用docker-compose)

导入sql脚本(教程中有)
PARAMS设置容器加载配置文件

配置执行器项目

1. 配置pom文件，增加xxl-job-core依赖

<dependency>
    <groupId>com.xuxueli</groupId>
    <artifactId>xxl-job-core</artifactId>
    <version>2.1.0</version>
</dependency>

2. 修改application.yml文件

server:
  port: 8081
xxl:
  job:
    admin:
      addresses: http://192.168.1.130/xxl-job-admin
    executor:
      appname: xxl-job-executor-sample
      ip:
      port: 9999
      logretentiondays: 30
      logpath:
    accessToken:

3. XxlJobConfig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.executor.appname}")
    private String appName;

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

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

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

    @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.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }
}

4. 任务类HelloHandler

/**
 * @author wzh
 * @date 2019/12/9 - 16:13
 * 开发步骤：
 * 继承"IJobHandler"：“com.xxl.job.core.handler.IJobHandler”；
 * 注册到Spring容器：添加“@Component”注解，被Spring容器扫描为Bean实例；
 * 注册到执行器工厂：添加“@JobHandler(value="自定义jobhandler名称")”注解，注解value值对应的是调度中心新建任务的JobHandler属性的值。
 * 执行日志：需要通过 "XxlJobLogger.log" 打印执行日志；
 */
@JobHandler(value = "helloHandler")
@Component
public class HelloHandler extends IJobHandler {
    @Override
    public ReturnT<String> execute(String s) throws Exception {
        XxlJobLogger.log("Hello Handler is deal");
        Thread.sleep(1000);
        return ReturnT.SUCCESS;
    }
}

遇见的问题

1. 执行器启动报错
2. 执行器不能注册进任务中心
最后使用了制作镜像+xxl-job-core的2.1.2-SNAPSHOT版解决(拉取时拉的快照版..)

制作镜像

Dockerfile

FROM openjdk:8-jre
MAINTAINER xuxueli

ENV PARAMS=""

ENV TZ=PRC
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

ADD xxl-job-admin-*.jar /app.jar

ENTRYPOINT ["sh","-c","java -jar /app.jar $PARAMS"]
