Elastic Job3.0

添加依赖

        <dependency>
            <groupId>org.apache.shardingsphere.elasticjob</groupId>
            <artifactId>elasticjob-lite-core</artifactId>
            <version>3.0.0-alpha</version>
        </dependency>

配置文件添加

elasticJob:
  regCenter:
    serverLists: localhost:2181
    namespace: live-task

elastic-job:
  jobs:
    - jobName: testJob
      cron: '*/5 * * * * ?'

添加ElasticJob配置类:

注册中心

package com.wjc.server.config;

import org.apache.shardingsphere.elasticjob.reg.base.CoordinatorRegistryCenter;
import org.apache.shardingsphere.elasticjob.reg.zookeeper.ZookeeperConfiguration;
import org.apache.shardingsphere.elasticjob.reg.zookeeper.ZookeeperRegistryCenter;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @author wjc
 * @description
 * @date 2020/10/23
 */
@Configuration
public class ElasticRegCenterConfig {
    @Bean(initMethod = "init")
    public CoordinatorRegistryCenter regCenter(
            @Value("${elasticJob.regCenter.serverLists}") final String serverList,
            @Value("${elasticJob.regCenter.namespace}") final String namespace) {
        return new ZookeeperRegistryCenter(new ZookeeperConfiguration(serverList, namespace));
    }
}

 

配置对应实体类

package com.wjc.server.config;

import lombok.Data;

/**
 * @author wjc
 * @description
 * @date 2020/10/23
 */
@Data
public class JobEntity {

    /**
     * 任务名称
     */
    private String jobName;
    /**
     * 分片数量
     */
    private int shardingTotalCount = 1;
    /**
     * cron表达式
     */
    private String cron;
    /**
     * 当前分片参数
     */
    private String shardingItemParameters;
    /**
     * 当前任务参数
     */
    private String jobParameter;
    /**
     * 任务类型 0.SimpleJob 1.DataflowJob 2.ScriptJob
     */
    private Integer type = 0;
    /**
     * 任务说明
     */
    private String description;

}

 

获取任务配置

package com.wjc.server.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.ArrayList;
import java.util.List;

/**
 * @author wjc
 * @description
 * @date 2020/10/23
 */
@Data
@Component
@ConfigurationProperties(prefix = "elastic-job")
public class JobEntityConfig {
    private List<JobEntity> jobs = new ArrayList<>();
}

 

最终配置类

package com.wjc.server.config;

import org.apache.shardingsphere.elasticjob.api.ElasticJob;
import org.apache.shardingsphere.elasticjob.api.JobConfiguration;
import org.apache.shardingsphere.elasticjob.lite.api.bootstrap.impl.ScheduleJobBootstrap;
import org.apache.shardingsphere.elasticjob.reg.base.CoordinatorRegistryCenter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Configuration;

import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.List;

/**
 * @author wjc
 * @description
 * @date 2020/10/23
 */
@Configuration
public class ElasticJobConfig {

    @Autowired
    private CoordinatorRegistryCenter regCenter;
    @Autowired
    private ApplicationContext applicationContext;
    @Autowired
    private JobEntityConfig jobEntityConfig;

    @PostConstruct
    public void executor(){
        List<JobConfiguration> list = getJobConfiguration();
        list.forEach(job -> new ScheduleJobBootstrap(regCenter, (ElasticJob)applicationContext.getBean(job.getJobName()), job).schedule());
    }

    public List<JobConfiguration> getJobConfiguration(){
        List<JobEntity> jobEntityList = jobEntityConfig.getJobs();
        List<JobConfiguration> list = new ArrayList<>(jobEntityList.size());
        jobEntityList.forEach(jobEntity -> list.add(JobConfiguration.newBuilder(jobEntity.getJobName(), jobEntity.getShardingTotalCount()).cron(jobEntity.getCron()).description(jobEntity.getDescription()).shardingItemParameters(jobEntity.getShardingItemParameters()).build()));
        return list;
    }
}
