原创 Could not resolve placeholder ‘mail.sender‘ in value “${mail.sender}“
偶然一次使用@Value来给参数设置初始化值（如下），但是项目启动一直报错：Could not resolve placeholder 'mail.sender' in value "${mail.sender}"经过一顿排查，原因是需要对@Value里的参数设置默认值，最简单的写法加上“:”即可。核对了application.yml配置，确认配置无误。

原创 mongodb插入数据报Cannot create namespace testk2 in multi-document transaction
问题现象：当向mongodb插入数据报Cannot create namespace testk2 in multi-document transaction。原因分析：检查发现要插入的集合collection不存在，经搜索资料发现，在一个事务中，要操作的集合必须要先存在，事务不能在不存在的集合上进行相关操作。所以，问题原因就是要先把这个集合创建，然后再插入对应数据；
