Интеграция с PageHelper подробных примеров SpringBoot
1.PageHelper Профиль
PageHelper официальный адрес сайта:
Аннотация: com.github.pagehelper.PageHelper является простой в использовании бесплатно с открытым исходным кодом физической страницы Mybatis сторонних плагинов.
PageHelper является простой в использовании бесплатно с открытым исходным кодом физической страницы Mybatis сторонних плагинов, на самом деле, я не хочу, чтобы добавить слово легко, но похвалить бесплатно с открытым исходным кодом плагина автор возвышенного духа, я, не колеблясь, чтобы добавить удобный как слово хвалы.
Первоначально думали, что нумерация страниц плагин, он должен быть очень простым, но многие PageHelper сложнее, чем я думал, что это будет, это очень мощный и очень тщательно, мощный пользователь может не должны быть настолько универсальны, тщательное обращение к возможному двойного назначения , Но, я думаю, как постраничной плагина для выполнения этой задачи является фундаментальными физическими страницы, многие других умные не нужны, чтобы держать его достаточно глуп настолько глуп, жаргона называется глупо, просто красиво.
Мы кратко представить основной смысл и использование параметров конфигурации PageHelper, фокусируется на PageHelper как реализация принципа Mybatis постраничных плагин.
