jackson 将地图转换为对象列表

Question

我有以下

Sinister

实体

@Document
@Getter
@Setter
@ToString
@AllArgsConstructor
@NoArgsConstructor
@Builder(toBuilder = true)
@JsonInclude(JsonInclude.Include.NON_EMPTY)
public class Sinister {
    ....
}

public String on(FindSinister query) {
    final Map<Object, Object> hashEntries = redisTemplate.opsForHash().entries(Sinister.class.getSimpleName());
    final List<Object> allValuesFromHash = new ArrayList<>(hashEntries.values());
    if (CollectionUtils.isNotEmpty(allValuesFromHash)) {
        final JavaType targetType = objectMapper.getTypeFactory().constructCollectionType(List.class, Sinister.class);
        final List<Sinister> sinisters = objectMapper.readValue(objectMapper.writeValueAsString(allValuesFromHash), targetType);
    }
    ....
}

当我从redis获取实体列表时，我有上述方法，函数

entries

返回一个

Map<Object, Object>

，当我试图将它转换为险恶列表时，我有以下错误：

    com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `Sinister` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('Sinister')
