如何在Sling中创建JobConsumer ?

Question

根据Apache Sling官方网站(https://sling.apache.org/documentation/bundles/apache-sling-eventing-and-job-handling.html#job-consumers)，这是编写JobConsumer的方法。

import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Service;
import org.apache.sling.event.jobs.Job;
import org.apache.sling.event.jobs.consumer.JobConsumer;
@Component
@Service(value={JobConsumer.class})
@Property(name=JobConsumer.PROPERTY_TOPICS, value="my/special/jobtopic",)
public class MyJobConsumer implements JobConsumer {
public JobResult process(final Job job) {
// process the job and return the result
return JobResult.OK;
}
}

然而@Service和@Property都是被弃用的注解。我想知道创建JobConsumer的正确方法。有谁知道如何编写与上面相同的代码吗?

Answer 1

在AEM中不推荐使用scr注释，建议以后使用官方的OSGi声明性服务注释。Adobe有一个关于使用OSGi R7注释的研讨会。

新的写法是

import org.osgi.service.component.annotations.Component;
import org.apache.sling.event.jobs.Job;
import org.apache.sling.event.jobs.consumer.JobConsumer;
@Component(
immediate = true,
service = JobConsumer.class,
property = {
JobConsumer.PROPERTY_TOPICS +"=my/special/jobtopic"
}
)
public class MyJobConsumer implements JobConsumer {
public JobResult process(final Job job) {
// process the job and return the result
return JobResult.OK;
}
}
