xxl-job 执行器调度

源码:https://github.com/xuxueli/xxl-job

按文档启动xxl-job-admin后,可以自己写执行器

执行器:

新建springboot服务 选中spring web、Mysql Driver、JDBC API、Mybatis Framework等依赖

pom.xml添加

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

application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/xxl_job?Unicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=7546857
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
server.port=8082

### 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 executor address
xxl.job.executor.appname=xxl-test
xxl.job.executor.ip=
xxl.job.executor.port=30020
### xxl-job, access token
xxl.job.accessToken=
### xxl-job log path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### xxl-job log retention days
xxl.job.executor.logretentiondays=-1

接下来创建一个XxlJobConfig类，进行扫描JobHandler的位置。

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.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(initMethod = "start", destroyMethod = "destroy")
    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;
    }
}

最后创建继承了IJobHandler的类，也就是JobHandler，例子如下：

import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.IJobHandler;
import com.xxl.job.core.handler.annotation.JobHandler;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;


@Component
@JobHandler("test")
public class TestJobHander extends IJobHandler {
    private Logger logger= LoggerFactory.getLogger(TestJobHander.class);
    @Override
    public ReturnT<String> execute(String s) throws Exception {
        System.out.println("11111111111111111111");
        logger.info("lalalala");
        return ReturnT.SUCCESS;
    }
}
