Jackson 可以在 (de)/序列化期间使用具有包含在 java.util.Map

Question

这是我的初始设置

String json = "{'text': 'what is my balance', 'mid': 'D1dexnEBTCefEdRWveEt8A', 'seq': 73}";

import java.io.Serializable;

import java.time.LocalDateTime;

import org.apache.commons.lang3.builder.EqualsBuilder;

import com.fasterxml.jackson.annotation.JsonProperty;

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;

@JsonDeserialize(builder = Messages.MessageBuilder.class)

public class Message implements Serializable {

  @JsonProperty("id")

  public final String id;

  @JsonProperty("botId")

  public final String botId;

  @JsonProperty("userId")

  public final String userId;

  public final String userIdKey;

  public boolean echoText=false;

  public String text;

  public String timeZone;

  public volatile String username;

  @JsonProperty("conversationId")

  public volatile String conversationId;

  public volatile int kaiUserId;

  public volatile String token;

  public final LocalDateTime inboundReceivedAt;

  public volatile LocalDateTime outboundSentAt;

  final String key;

  private final int _hashCode;

  public volatile long lastAccess = System.currentTimeMillis();

  public Message(final String pMessageId, final String pUserId, final String pBotId, final String pConversationId, final String pText) {

    id = pMessageId;

    userId = pUserId;

    botId = pBotId;

    conversationId = pConversationId;

    text = pText;

    inboundReceivedAt = LocalDateTime.now();

    key = id + "-" + userId + "-" + botId;

    userIdKey = userId + "~" + botId;

    _hashCode = key.hashCode();

  }

  void touch() { lastAccess = System.currentTimeMillis(); }

  @Override public int hashCode() { return _hashCode; }

  @Override public boolean equals(final Object pObject) {

    if (!(pObject instanceof Message)) { return false; }

    return new EqualsBuilder().append(id, ((Message)pObject).id)

                              .append(botId, ((Message)pObject).botId)

                              .append(userId, ((Message)pObject).userId)

                              .isEquals();

  }
