The reason why the entity class in the database is changed into hump naming

• Because it's more elegant , And more standardized .
• such as Mysql The database field is named blogTitle, No problem at first sight , But in the oracle It becomes BLOGTITLE, here we are postgresql It becomes blogtitle, Very bad readability .
• For example, the entity class field is named blog_title, be get When I was young, I became getBlog_title(), Also very unsightly .
• But this is a small specification for more elegant code , If you feel it doesn't hinder the overall aesthetics , Database fields can also become humps , Entity classes can also become underlined .
