无法将字符串反序列化为 Java 对象

Question

(数据class)Entity.java

@Data
@Accessors(chain = true)
@AllArgsConstructor
@NoArgsConstructor
public class Entity implements Serializable {
    private String id;
    private String name;
    private String status;
    private ZonedDateTime registrationDatetime;
    private ZonedDateTime updatedDatetime;
    private ZonedDateTime createdDatetime;
}

(数据class)Entities.java

@Data
@AllArgsConstructor
@JsonDeserialize
public class Entities implements Serializable {
    private List<Entity> entities;
}

我试过运行这个语句：

TypeReference<ResponseModel<Entities>> typeReference = new TypeReference<ResponseModel<Entities>>() {};
ResponseModel<Entities> response = objectMapper.readValue(result.getResponse().getContentAsString(), typeReference);

我得到了这个错误：

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `model/Entities` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

我已经把 @JsonDeserialize 和 implements Serializable 我错过了什么？

Answer 1

尝试为实体也提供@NoArgsConstructor class。这应该有效。
