简要
该文章只是作者从自己开发的代码中截取的一部分，只是做一个参考；实际上需要自己在该代码基础上进行调整和优化，有疑问可以在评论区进行提问
一、数据库ER设计
聊天功能主要涉及到两张表，message和user表，message用来存信息，user表用来关联用户信息，主要是拿来取用户昵称以及头像
message表创建：
CREATE TABLE `chat_message` (
`id` int NOT NULL AUTO_INCREMENT COMMENT '自增主键id',
`send_user_id` varchar(20) NOT NULL COMMENT '发送用户id',
`accept_user_id` varchar(20) NOT NULL COMMENT '接手用户id',
`type` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL COMMENT '消息类型（图片：img，视频：video，文本：text）',
`content` text COMMENT '发送内容',
`readed` int NOT NULL DEFAULT '0' COMMENT '是否阅读',
`delete` int NOT NULL DEFAULT '0' COMMENT '是否删除',
`send_time` datetime NOT NULL COMMENT '发送时间',
PRIMARY KEY (`id`),
KEY `user_id` (`send_user_id`,`accept_user_id`) USING BTREE COMMENT 'userId索引'
) ENGINE=InnoDB AUTO_INCREMENT=160 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;user表创建：
CREATE TABLE `wx_user` (
`id` int NOT NULL AUTO_INCREMENT COMMENT '自增id',
`user_id` varchar(20) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NOT NULL COMMENT '用户ID',
`nickName` varchar(20) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci DEFAULT NULL COMMENT '昵称',
`headImg` varchar(150) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci DEFAULT NULL COMMENT '头像链接',
`phone` varchar(11) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci DEFAULT NULL COMMENT '电话',
`openid` varchar(100) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci DEFAULT NULL COMMENT 'openID',
`unionid` varchar(100) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci DEFAULT NULL COMMENT 'unionID',
`status` int NOT NULL DEFAULT '0' COMMENT '状态 0：使用中 1：冻结中 2：长时间未使用',
`created_time` datetime DEFAULT NULL COMMENT '创建时间',
`modefied_time` datetime DEFAULT NULL COMMENT '修改时间',
PRIMARY KEY (`id`) USING BTREE,
UNIQUE KEY `user_id` (`user_id`),
UNIQUE KEY `openID` (`openid`) USING BTREE,
UNIQUE KEY `unionID` (`unionid`) USING BTREE,
UNIQUE KEY `phone` (`phone`) USING BTREE,
KEY `id` (`id`,`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8mb3 ROW_FORMAT=DYNAMIC;二、后端接口设计
entity:
Message.java
package com.example.wxapi.entity.MessageEntity;
import com.example.wxapi.entity.UserEntity.WxUser;
import lombok.Data;
@Data
public class ChatMessage {
private Integer id;

private String type;
private String content;
private Integer soundTIme;
private String sendTime;
private Integer readedNum;
private WxUser wxUser;
}WxUser.java
package com.example.wxapi.entity.UserEntity;
import lombok.Data;
@Data
public class WxUser {
private Integer id;
private String userId;
private String nickName;
private String headImg;
private String phone;
private String openid;
private String unionid;
private Integer status;
private String createdTime;
private String modefiedTime;
