文章列表查询
表的拆分-垂直分表
- 垂直分表: 将一个表的字段分散到多个表中，每个表存储其中一部分字段
- 优势:
- 减少IO争抢，减少锁表的几率，查看文章概述与文章详情互不影响
- 充分发挥高频数据的操作效率，对文章概述数据操作的高效率不会被操作文章详情数据的低效率所拖累
- 拆分规则:
- 把不常用的字段单独放在一张表
- 把text，blob等大字段拆分出来单独放在一张表
- 经常组合查询的字段单独放在一张表中
接口实现
- ArticleHomeDto
public class ArticleHomeDto { // 最大时间 Date maxBehotTime; // 最小时间 Date minBehotTime; // 分页size Integer size; // 频道id String tag; } - ArticleHomeController

文章详情
实现分析
- 方案1: 用户某一条文章, 根据文章的id去查询文章内容表, 返回渲染页面
- 方案2: 静态模板展示
- 根据文章内容通过模板技术(freemarker)生成静态的html文件
- 将文件存入分布式文件系统(MinIO)中
- 将生成好的html访问路径存入文章表中
- 获取html的url
- 访问静态页面

=和==都是判断相等
- 运算符
- 建议gt代替
>, FreeMarker会把>解释为标签的结束字符, 也可以使用括号来避免
- 建议gt代替
- 空值处理
// ?? 判断变量是否存在 <#if stus??> ... </#if> // ! 缺失变量默认值 ${name!''} // 如果是嵌套对象建议使用() ${(stu.name)!''} - 内建函数
// 集合大小 stus集合的大小: ${stus?size} // 日期格式化 现在时间: ${today?datetime} 现在时间: ${today?string("yyyy年MM月")} // 将数字转成字符串 ${point?c} // assign标签是定义变量 // 将json字符串转成对象 <#assign text="{'bank':'工商银行', 'account':'123456789123'}" /> <#assign data=text?eval /> 开户行: ${data.bank} 账号: ${data.account}
