在[Elastic Job 入门教程（一）— 与Spring Boot集成][Elastic Job _ _Spring Boot]这篇文章中，我们简单介绍了Spring Boot与Elastic Job 的集成，并简单实现了**SimpleJob**类型作业。本章，我们介绍Spring Boot框架下如何实现Elastic Job的**Script Job**类型作业。

**application.yml中脚本作业配置**

scriptJob:
      cron: 0/5 * * * * ?
      shardingTotalCount: 2
      shardingItemParameters: 0=CIB,1=ICBC
      jobDescription: "elastic script job"
      jobParameter: "hello elastic script job"
      jobName: "elastic script job name"
      scriptCommandLine: "d:/run.bat"

**定义Bean获取脚本作业属性**

@Getter
    @Setter
    @NoArgsConstructor
    @AllArgsConstructor
    @ToString
    @Configuration
    @ConfigurationProperties(prefix = "scriptJob")
    public class ElasticScriptJobProperties {
        private String cron;
        private int shardingTotalCount;
        private String shardingItemParameters;
        private String jobDescription;
        private String jobParameter;
        private String jobName;
        private String scriptCommandLine;
    
    }

**脚本作业配置**

@Configuration
    public class ElasticScriptJobConfig {
    
        @Autowired
        private ElasticScriptJobProperties elasticScriptJobProperties;
    
        @Bean
        public LiteJobConfiguration scriptLiteJobConfiguration() {
            JobCoreConfiguration.Builder builder = JobCoreConfiguration.newBuilder(elasticScriptJobProperties.getJobName()
                    , elasticScriptJobProperties.getCron()
                    , elasticScriptJobProperties.getShardingTotalCount());
            JobCoreConfiguration jobCoreConfiguration = builder
                    .shardingItemParameters(elasticScriptJobProperties.getShardingItemParameters())
                    .description(elasticScriptJobProperties.getJobDescription())
                    .jobParameter(elasticScriptJobProperties.getJobParameter())
                    .build();
            ScriptJobConfiguration scriptJobConfiguration = new ScriptJobConfiguration(jobCoreConfiguration
                    , elasticScriptJobProperties.getScriptCommandLine());
            return LiteJobConfiguration
                    .newBuilder(scriptJobConfiguration)
                    .overwrite(true)
                    .build();
        }
    
    }

**脚本作业定义**

@Component
    public class ElasticScriptJob {
        @Autowired
        private ZookeeperRegistryCenter regCenter;
    
        @Autowired
        private LiteJobConfiguration scriptLiteJobConfiguration;
    
        @Bean(initMethod = "init")
        public JobScheduler scriptJob() {
            return new JobScheduler(regCenter, scriptLiteJobConfiguration);
        }
    }
