In addition, trick such as "text/cache" cannot work in Firefox/opera, because these two browsers refuse to download scripts of types they do not know, in this way, it is impossible to "pre-load. But this will not cause problems, because the two browsers can directly use the aboveScript Dom ElementTo load external scripts.

The project uses spring Data JPA and hibernate to connect and process the MySQL database, which is, of course, just one way, and you can use spring JDBC or mybatis.?? Spring Data JPA is a sub-project of spring data, which is mainly used to simplify the implementation of the database access layer, using spring data JPA to easily make additions, deletions, pagination, sorting, and more.
