Elastic Job 入门教程（四）— 事件追踪

拼搏现实的明天。 2022-05-10 05:22 656阅读 0赞

> 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);
        }
