Hazelcast

Question

我有一个类（A），它包含原始数据类型和非原始数据类型。我还有列表对象列表，例如List obj，其中XYZ是其他类。当我实例化并在地图上做到时，我得到了

com.hazelcast.nio.serialization.HazelcastSerializationException：无法序列化错误。我该如何解决呢。

@Entity(value = "A", noClassnameStored = true)
public class A implements Serializable
{
@Id
private String p;
private String jrr;
private String ring;
private List<Signature> sam;
private String noth; 
private List<GroupRole> got;
private List<String> lost;
private List<String> folders;
public List<FolderDef> folders;
private List<ViewConfig> views;
private List<FavoriteContact> favorites;
private String crtBy;
private Date crtDate;
private String modBy;
private Date modDate;
private Boolean active;
private List<Preference> preferences;

private List<nah> chet;

private List<yup> ellis;

private Boolean pp;

private Boolean oo;

private String cc;
private String aa;
private String bb;

private String tt;
private String uu;
private String dd;
private String xx;
private String ii;
private Boolean zz;

private String x;

private byte[] y;

private Boolean z;

}

还有getter和setter方法，我忽略了

Answer 1

通过向所有嵌套类和类A

添加实现Serializable来修复它

Answer 2

所有嵌套类都需要可序列化。要调试SerializationException并确定哪个属性不是Serializable，您可以通过设置

在java中启用扩展调试选项
