我创建了自定义的Serializable类,并将其添加到必要的Sling Job的有效负载中
public SomeClass extends Serializable {
//Implementaton details
}
.......
//some service
Map<String, Object> payload = new HashMap<>();
payload.put("property1", someClassObject);
jobManager.createJob("some/job/topic").properties(payload).add();
成功创建并分配了重复使用的作业,但是未触发process
的{{1}}方法。
我已经在org.apache.sling.event.jobs上启用了TRACE日志级别,日志说的是一样的:添加并分配了作业,没有其他反应:
JobConsumer
如果我传递标准的可序列化对象,如String,Integer等;作业开始了,我可以在日志中找到证据:

如何解决吊带作业处理问题?
在AEM 6.4.2和6.4.3上进行了测试
答案 0 :(得分:4)
问题是您的自定义类被禁止反序列化。实际上,禁止所有类反序列化,如here所述。您应该将要反序列化的类列入白名单。
仅当在 org.apache.sling.event.impl 而不是 org.apache.sling.event上创建调试记录器时,才会看到特定的 RuntimeException 。职位
