mysql中date与datetime的区别
date类型可用于需要一个日期值而不需要时间部分时。MySQL 以 'YYYY-MM-DD
' 格式检索与显示date值。支持的范围是 '1000-01-01' 到'9999-12-31'。
datetime类型可用于需要同时包含日期和时间信息的值。MySQL 以 'YYYY-MM-DD HH:mm:ss
'格式检索与显示 DATETIME 类型。
支持的范围是'1000-01-0100:00:00' 到 '9999-12-3123:59:59'。(“支持”的含义是,尽管更早的值可能工作,但不能保证他们均可以。)
若mysql中指定字段类型是DateTime,则后台TimeStamp timeStamp=new TimeStamp(new Date.getTime)或Date date=new Date();
并且mybatis中:mapper.xml里JDBCType=TIMESTAMP---->这才是重点

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
