榛树。序列化失败

Question

我用过

• Apache Camel 2.23.4；
• Hazelcast 3.12.6.

更新 Apache Camel：

• Apache Camel 3.2.0；
• Hazelcast 3.12.6.

在向 hazelcast IMap 添加对象时更新 apache camel 后，我得到一个序列化异常。

@lombok.Value
@lombok.AllArgsConstructor
public class Tasks implements Serializable {
  private String id;
  private String correlationId;
  private String key;
  private Map<String, Object> body;
  private Map<String, Object> props;
  private Boolean timer;
}

当放置在地图上的对象发生异常时

IMap<String, Tasks> IMapTasks=hazelcastInstance.getMap(TASK_MAP_NAME);
IMapTasks.put(task.getId(), taks);

堆栈跟踪：

有什么想法吗？

Answer 1

使用@lombok.Value 使字段成为最终字段。

java.io.Serializable 需要一个 noargs 构造函数

所以你可能需要

@lombok.AllArgsConstructor
@lombok.NoArgsConstructor
public class Tasks implements Serializable {
  private String id;
  private String correlationId;
  private String key;
