这个错误是因为在反序列化过程中，Jackson库无法将字符串 "2023-05-23 16:53:28" 转换为 java.sql.Timestamp 对象。这通常是由于日期字符串的格式与 Timestamp 的默认格式不匹配导致的。

你可以尝试更改日期字符串的格式，使其与 Timestamp 的默认格式匹配。或者，你可以创建一个自定义的反序列化器来处理此日期格式。

以下是一个示例自定义反序列化器：

public class TimestampDeserializer extends JsonDeserializer<Timestamp> {
    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    @Override
    public Timestamp deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
        String dateString = jsonParser.getText();
        try {
            Date date = dateFormat.parse(dateString);
            return new Timestamp(date.getTime());
        } catch (ParseException e) {
            throw new IOException("Error parsing date string: " + dateString, e);
        }
    }
}

然后在你的实体类中使用此自定义反序列化器：

@JsonDeserialize(using = TimestampDeserializer.class)
private Timestamp timestampField;
