From a907f8485c9d8bea82c71be7364c4c511e5e429a Mon Sep 17 00:00:00 2001 From: wzy1024 <395778325@qq.com> Date: 星期二, 04 四月 2023 11:58:26 +0800 Subject: [PATCH] 导出Excel,@Excel注解使用dictType属性时,如果有大量的字典数据,就会有大量的查询redis(打开、关闭),导致特别慢。于是使用map存储字典数据,相同的key就不需要再次去查询redis,大大提高了导出效率。 --- ruoyi-system/src/main/resources/mapper/system/SysNoticeMapper.xml | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/ruoyi-system/src/main/resources/mapper/system/SysNoticeMapper.xml b/ruoyi-system/src/main/resources/mapper/system/SysNoticeMapper.xml index 76caf2d..6915a14 100644 --- a/ruoyi-system/src/main/resources/mapper/system/SysNoticeMapper.xml +++ b/ruoyi-system/src/main/resources/mapper/system/SysNoticeMapper.xml @@ -18,7 +18,7 @@ </resultMap> <sql id="selectNoticeVo"> - select notice_id, notice_title, notice_type, notice_content, status, create_by, create_time, update_by, update_time, remark + select notice_id, notice_title, notice_type, cast(notice_content as char) as notice_content, status, create_by, create_time, update_by, update_time, remark from sys_notice </sql> -- Gitblit v1.9.2
