SpringJobScheduler是elasticjob 为调用spring bean的job类设计的scheduler，在example，需要使用代码生成bean，如下为example的代码
@Bean
public SimpleJob simpleJob() {
return new SpringSimpleJob();
}
@Bean(initMethod = "init")
public JobScheduler simpleJobScheduler(final SimpleJob simpleJob, @Value("${simpleJob.cron}") final String cron, @Value("${simpleJob.shardingTotalCount}") final int shardingTotalCount,
@Value("${simpleJob.shardingItemParameters}") final String shardingItemParameters) {
return new SpringJobScheduler(simpleJob, regCenter, getLiteJobConfiguration(simpleJob.getClass(), cron, shardingTotalCount, shardingItemParameters), jobEventConfiguration);
}
private LiteJobConfiguration getLiteJobConfiguration(final Class<? extends SimpleJob> jobClass, final String cron, final int shardingTotalCount, final String shardingItemParameters) {
return LiteJobConfiguration.newBuilder(new SimpleJobConfiguration(JobCoreConfiguration.newBuilder(
jobClass.getName(), cron, shardingTotalCount).shardingItemParameters(shardingItemParameters).build(), jobClass.getCanonicalName())).overwrite(true).build();
}
如果对每个类都需要使用@bean来创建，还是比较麻烦的，实际上可以使用applicationContext.getbean来自动创建，以下为实现代码。
JobScheduler scheduler = null;
Class<?> c = null;
try {
c = Class.forName(jobClass);
Object b = applicationContext.getBean(c);
// Object b = ContextUtils.getBean(jobClass);
if (jobEventConfig == null) {
scheduler = new SpringJobScheduler((ElasticJob) b, regCenter, liteJobConfig,
new EmptyElasticJobListener());
// scheduler =new JobScheduler(regCenter, liteJobConfig);
} else {
scheduler = new SpringJobScheduler((ElasticJob) b, regCenter, liteJobConfig, jobEventConfig);
// scheduler = new JobScheduler(regCenter, liteJobConfig, jobEventConfig);
}
scheduler.getSchedulerFacade().updateJobConfiguration(liteJobConfig);
logger.info("create SpringJobScheduler for class:" + jobClass);
} catch (ClassNotFoundException | BeansException e) {
logger.info("can't found class or create bean, use JobScheduler to replace SpringJobScheduler");
if (jobEventConfig == null) {
scheduler = new JobScheduler(regCenter, liteJobConfig);
} else {
scheduler = new JobScheduler(regCenter, liteJobConfig, jobEventConfig);
}
scheduler.getSchedulerFacade().updateJobConfiguration(liteJobConfig);
}
// scheduler.init();
return scheduler;
job实现类和普通simplejob没有什么区别
@Component
public class SyncJobFromDatabaseJob implements SimpleJob {
public String getName() {
return this.getClass().getCanonicalName();
}
无论是否有带@Component注解以上代码都能生成对应的scheduler。
