guava-cache
Provides cache solution and session storage via: Guava.
exports
Cache
dependency
<dependency>
<groupId>org.jooby</groupId>
<artifactId>jooby-guava-cache</artifactId>
<version>1.6.6</version>
</dependency>
usage
App.java:
import org.jooby.guava.GuavaCache;
{
use(GuavaCache.newCache());
get("/", req -> {
Cache cache = require(Cache.class);
// do with cache...
});
}
options
cache configuration
A default cache will be created, if you need to control the number of entries, expire policy, etc… set the guava.cache property in application.conf, like:
guava.cache {
maximumSize = 10
concurrencyLevel = 2
}
or via com.google.common.cache.CacheBuilderSpec syntax:
guava.cache = "maximumSize=10,concurrencyLevel=2"
multiple caches
Just add entries to: guava., like:
# default cache (don't need a name on require calls)
guava.cache = "maximumSize=10"
guava.cache1 = "maximumSize=1"
guava.cacheX = "maximumSize=100"
{
get("/", req -> {
Cache defcache = require(Cache.class);
Cache cache1 = require("cache1", Cache.class);
Cache cacheX = require("cacheX", Cache.class);
});
}
type-safe caches
Type safe caches are provided by calling and creating a new GuavaCache subclass:
{
// please notes the {} at the line of the next line
use(new GuavaCache<Integer, String>() {});
}
Later, you can inject this cache in a type-safe manner:
@Inject
public MyService(Cache<Integer, String> cache) {
...
}
guava session store
dependency
<dependency>
<groupId>org.jooby</groupId>
<artifactId>jooby-guava-cache</artifactId>
<version>1.6.6</version>
</dependency>
usage
This module comes with a Session.Store implementation. In order to use it you need to define a cache named session in your application.conf file:
guava.session = "maximumSize=10"
And set the GuavaSessionStore:
import org.jooby.guava.GuavaCache;
import org.jooby.guava.GuavaSessionStore;
{
use(GuavaCache.newCache());
session(GuavaSessionStore.class);
}
You can access to the session via name:
{
get("/", req -> {
Cache cache = require("session", Cache.class);
});
}
