1. Docker安装之后需要重启, 否则报:
Error mounting devices cgroup: mountpoint for devices not found
2. Request.getServerPort是取的Http Request里面HostHeader的Port部分, 所以Nginx要做
3. JDBCType 对于Select没用的.
The JDBC type is only required for nullable columns upon insert, update or delete.
On page 33 in this document is a list of supported JDBC types.
For thejavaTypeattribute it says:
iBATIS can usually figure out the type if you’re mapping to a
JavaBean. However, if you are mapping to a HashMap, then you should
specify the javaType explicitly to ensure the desired behaviour.
4. mvc:annotation-driven 初始化了一个自己的JacksonView
所以修改日期格式时候不生效
5. JS里面要区分Json 对象和字符串Json
否则Ajax提交时候要出问题
