中科国力的一些笔记

ASR ( automatic speech recognition ) 自动语音识别

TTS 文本转成语音

mac 打包部署到服务器出现循环依赖

在循环以来的类上加上@Lazy既可解决此问题

MyBatis Plus 的一些Api

lt：less than 小于
le：less than or equal to 小于等于
eq：equal to 等于
ne：not equal to 不等于
ge：greater than or equal to 大于等于
gt：greater than 大于

mysql脚本

create table sys_memu_bak as select * from sys_menu 备份数据库

use inside_manage;
ALTER TABLE im_corpus_audio ADD dept_city_name VARCHAR(255) comment "地市标识";
ALTER TABLE im_corpus_audio_content ADD dept_city_name VARCHAR(255) comment "地市标识";

mybatis-plus

一些奇怪且简单的链式操作

 Long count = new LambdaQueryChainWrapper<>(contactDetailMapper)
                                    .eq(ContactDetail::getContactId, contactDetail.getContactId())
                                    .count();

局方

代表电信

Assert.assertEquals方法

Assert.assertEquals(5, userList.size()); 当两个参数不想等，抛出异常

bug

spring boot2.6.1 继承swagger报错：

swagger Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

因为Springfox使用的路径匹配是基于AntPathMatcher的，而Spring Boot 2.6.X使用的是PathPatternMatcher。

解决办法，修改application.yal

spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher

ftp 文件下载，处理文件

资源相关的流操作要用Try-with-resources会自动关闭流，还要把整个连接放在try里以防编码出问题，导致文件下载失败
所有代码都要做好异常处理，避免因异常导致程序停止
