1、消息点赞、喜欢、评论列表
在消息模块中的点赞、喜欢、评论列表，是别人对自己发布的内容的操作，其实现基本一致，所以在一起实现。
效果：

点击首页的今日佳人或任意推荐人的图片就会进入个人主页页面，效果如下：
在个人主页的页面中，会显示出个人信息、缘分值、个人相册等内容。
3.1、个人信息
3.1.1、dubbo服务
需要在dubbo服务中提供查询缘分值的接口服务。
3.1.1.1、定义接口

3.3、整合测试
4、聊一下
在个人主页中，点击聊一下按钮，会弹出回答问题窗口，输入答案后，系统会向对方发送一条陌聊消息，如果对方在陌聊消息中点击聊一下，他们就会成为好友。
用户1在用户2的个人主页中点击“聊一下”，流程如下：
4.1、陌聊问题
点击聊一下时，需要显示出问题，所以需要在mysql中存储用户的问题。
4.1.1、表结构
CREATE TABLE `tb_question` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`user_id` bigint(20) DEFAULT NULL COMMENT '用户id',

`created` datetime DEFAULT NULL,
`updated` datetime DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `user_id` (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@NoArgsConstructor
@AllArgsConstructor

if(ObjectUtil.isNotEmpty(question)){
return question.getTxt();
}
//默认的问题
return "你的爱好是什么？";
}
4.2.3、测试
4.3、回复陌生人问题
点击问题窗口中的“聊一下”，需要通过admin权限发送系统消息。
4.3.1、dubbo服务
4.3.1.1、定义接口
//com.tanhua.dubbo.server.api.HuanXinApi
/**

}
4.3.1.2、实现接口

return this.requestService.execute(targetUrl, body, Method.POST).isOk();
} catch (Exception e) {
log.error("发送消息失败~ targetUserName = " + targetUserName+", type = " + huanXinMessageType.getType()+", msg = " + msg, e);
}
return false;
}
4.3.2、APP接口服务
接口文档：https://mock-java.itheima.net/project/35/interface/api/641
4.3.2.1、TanHuaController

Long userId = Long.valueOf(param.get("userId").toString());
String reply = param.get("reply").toString();
Boolean result = this.tanHuaService.replyQuestion(userId, reply);
if (result) {
return ResponseEntity.ok(null);
}
} catch (Exception e) {
e.printStackTrace();
}
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
}
4.3.2.2、TanHuaService
//com.tanhua.server.service.TanHuaService
@Reference(version = "1.0.0")
private HuanXinApi huanXinApi;
public Boolean replyQuestion(Long userId, String reply) {
User user = UserThreadLocal.get();
UserInfo userInfo = this.userInfoService.queryUserInfoByUserId(user.getId());
//构建消息内容
Map<String, Object> msg = new HashMap<>();
msg.put("userId", user.getId());
msg.put("huanXinId", "HX_" + user.getId());
msg.put("nickname", userInfo.getNickName());
msg.put("strangerQuestion", this.queryQuestion(userId));
msg.put("reply", reply);
//发送环信消息
return this.huanXinApi.sendMsgFromAdmin("HX_" + userId,
HuanXinMessageType.TXT, JSONUtil.toJsonStr(msg));
}
4.3.3、测试
用户heima_37收到陌生人消息：
可以看到好友已经添加完成，可以在通讯录中选择好友进行聊天。
在陌聊消息中的“确认添加”功能，就是前面实现的添加联系人接口。
5、谁看过我
查询别人来访了我的主页的信息，其他用户在浏览我的主页时，需要记录访客数据。访客在一天内每个用户只记录一次。
查询数据时，如果用户查询过列表，就需要记录这次查询数据的时间，下次查询时查询大于等于该时间的数据。
如果，用户没有记录查询时间，就查询最近的5个来访用户。
页面效果如下：
