5.7 Cache

ActiveRecord can use caching to greatly improve performance, and the following code is an example of Cache usage:

public void list() {
List<Blog> blogList = Blog. dao .findByCache("cacheName", "key", "select * from blog");
setAttr("blogList", blogList).render("list.html");
}

The cacheName in the findByCache method above needs to be configured in the ehcache .xml such as: slt;cache name"cacheName" ... & gt; 。 M odel.paginateByCache (...), Db.findByCache (...), Db.paginateByCache (...) M ethods provide cache support. When used, simply pass in cacheName, key, and configure the corresponding cacheName .xml in the ehccache module.
