13.9.2. JCache CacheManager

<div class="paragraph">

JCache mandates that `CacheManager`s sharing the same URI and class loader be unique in JVM.

<div class="paragraph">

If you do not specify additional properties, the `JCacheRegionFactory` will load the default JCache provider and create the default `CacheManager`.
Also, `Cache`s will be created using the default `javax.cache.configuration.MutableConfiguration`.

</div>
<div class="paragraph">

In order to control which provider to use and specify configuration for the `CacheManager` and `Cache`s you can use the following two properties:

<div class="title">Example 333. JCache configuration</div>

<pre class="prettyprint highlight">`&lt;property
    name="hibernate.javax.cache.provider"
    value="org.ehcache.jsr107.EhcacheCachingProvider"/&gt;
&lt;property
    name="hibernate.javax.cache.uri"
    value="file:/path/to/ehcache.xml"/&gt;`</pre>
</div>
</div>
</div>
</div>
<div class="paragraph">

Only by specifying the second property `hibernate.javax.cache.uri` will you be able to have a `CacheManager` per `SessionFactory`.
