Elastic Job 入门教程（四）— 事件追踪

Elastic-Job提供了事件追踪功能，用于查询、统计和监控作业执行历史和执行状态。Elastic-Job-Lite在配置中提供了JobEventConfiguration，目前支持数据库方式配置。事件追踪所配置的DataSource数据库中会自动创建JOB_EXECUTION_LOG和JOB_STATUS_TRACE_LOG两张表以及若干索引。以下是代码示例：

定义数据源

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@ToString
@Configuration
@ConfigurationProperties(prefix = "spring.datasource")
public class DataSourceProperties {
    private String url;
    private String username;
    private String password;

    @Bean
    @Primary
    public DataSource getDataSource() {
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        return dataSource;
    }

}

定义JobEventConfiguration

@Configuration
public class JobEventConfig {
    @Autowired
    private DataSource dataSource;

    @Bean
    public JobEventConfiguration jobEventConfiguration() {
        return new JobEventRdbConfiguration(dataSource);
    }
}

作业中增加事件追踪配置

    ...
    
    @Autowired
    private JobEventConfiguration jobEventConfiguration;


    @Bean(initMethod = "init")
    public JobScheduler simpleJobScheduler() {
        return new SpringJobScheduler(serviceMonitor
                , regCenter
                , liteJobConfiguration
                , jobEventConfiguration
                , commonElasticJobListener);
    }

登录Console管理端，配置事件追踪数据源

查询作业执行历史
