elastic-job之Script类型作业实现

一、前序

如果你对elastic-job还不了解的话，建议你去看看我的《elastic-job分布式作业调度框架简介》，以下涉及到的参数配置请查看我的《elastic-job之Simple类型作业实现》

二、Script类型

Script类型作业意为脚本类型作业，支持shell，python，perl等所有类型脚本。只需通过控制台或代码配置scriptCommandLine即可，无需编码。执行脚本路径可包含参数，参数传递完毕后，作业框架会自动追加最后一个参数为作业运行时信息。

三、代码展示

package com.lwl.boot.job.script;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.attribute.PosixFilePermissions;

import com.dangdang.ddframe.job.config.JobCoreConfiguration;
import com.dangdang.ddframe.job.config.script.ScriptJobConfiguration;
import com.dangdang.ddframe.job.lite.api.JobScheduler;
import com.dangdang.ddframe.job.lite.config.LiteJobConfiguration;
import com.dangdang.ddframe.job.reg.base.CoordinatorRegistryCenter;
import com.dangdang.ddframe.job.reg.zookeeper.ZookeeperConfiguration;
import com.dangdang.ddframe.job.reg.zookeeper.ZookeeperRegistryCenter;

public class ApiJobScript {

	public static void main(String[] args) throws IOException {
		new JobScheduler(registryCenter(),configuration()).init();
	}

	
	private static CoordinatorRegistryCenter registryCenter() {
		//配置zookeeper
		CoordinatorRegistryCenter registryCenter = 
					new ZookeeperRegistryCenter(new ZookeeperConfiguration("localhost:2181", "elastic-job-demo"));
		registryCenter.init();
		return registryCenter;
	}

	
	private static LiteJobConfiguration configuration() throws IOException {
		 // 定义作业核心配置
		JobCoreConfiguration coreConfig = JobCoreConfiguration.newBuilder("scriptElasticJob", "0/5 * * * * ?", 3).build();
        ScriptJobConfiguration scriptJobConfig = new ScriptJobConfiguration(coreConfig, buildScriptCommandLine());
		
		LiteJobConfiguration config = LiteJobConfiguration.newBuilder(scriptJobConfig).build();
		
		return config;
	}


	private static String buildScriptCommandLine() throws IOException {
		//判断当前系统
	   if (System.getProperties().getProperty("os.name").contains("Windows")) {
            return Paths.get(ApiJobScript.class.getResource("/script/demo.bat").getPath().substring(1)).toString();
        }
        Path result = Paths.get(ApiJobScript.class.getResource("/script/demo.sh").getPath());
        Files.setPosixFilePermissions(result, PosixFilePermissions.fromString("rwxr-xr-x"));
        return result.toString();
	}
	
}

ScriptJobConfiguration主要参数：

coreConfig：作业核心配置

scriptCommandLine：脚本型作业执行命令行

demo.bat

@echo Sharding Context: %*

demo.sh

#!/bin/bash
echo Sharding Context: $*

四、启动
