play framework学习笔记之 使用缓存cache

Use a cache

例子代码



public static void allProducts() {

List<Product> products = Cache.get("products", List.class);

if(products == null) {

products = Product.findAll();

Cache.set("products", products, "30mn");

}

render(products);

}



Cache就是一个缓存了数据的Map，你不能保证它永远生存。

Configure memcached

You can connect to a distributed cache by specifying multiple daemon addresses:

你可以连接到分布式的多个缓存进程，多个守护进程地址，这些进程可以有jobs来开启

[code]memcached=enabled
memcached.1.host=127.0.0.1:11211
memcached.2.host=127.0.0.1:11212
