spring ehcache

<ehcache>
<!--
Sets the path to the directory where cache files are created.

If the path is a Java System Property it is replaced by its value in the
running VM.

The following properties are translated:
* user.home - User's home directory
* user.dir - User's current working directory
* java.io.tmpdir - Default temp file path

Subdirectories can be specified below the property e.g. java.io.tmpdir/one
-->
<diskStore path="java.io.tmpdir" />

<!--
Specifies a CacheManagerEventListenerFactory, be used to create a CacheManagerPeerProvider,
which is notified when Caches are added or removed from the CacheManager.

The attributes of CacheManagerEventListenerFactory are:
* class - a fully qualified factory class name
* properties - comma separated properties having meaning only to the factory.

Sets the fully qualified class name to be registered as the CacheManager event listener.

The events include:
* adding a Cache
* removing a Cache

Callbacks to listener methods are synchronous and unsynchronized. It is the responsibility
of the implementer to safely handle the potential performance and thread safety issues
depending on what their listener is doing.

If no class is specified, no listener is created. There is no default.

<cacheManagerEventListenerFactory class="" properties=""/>

<!--
(Enable for distributed operation)

Specifies a CacheManagerPeerProviderFactory which will be used to create a
CacheManagerPeerProvider, which discovers other CacheManagers in the cluster.

The attributes of cacheManagerPeerProviderFactory are:
* class - a fully qualified factory class name
* properties - comma separated properties having meaning only to the factory.

Ehcache comes with a built-in RMI-based distribution system with two means of discovery of
CacheManager peers participating in the cluster:
* automatic, using a multicast group. This one automatically discovers peers and detects
changes such as peers entering and leaving the group
* manual, using manual rmiURL configuration. A hardcoded list of peers is provided at
configuration time.

Configuring Automatic Discovery:
Automatic discovery is configured as per the following example:
-->
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1,
multicastGroupPort=4446" />
<!--

Valid properties are:
* peerDiscovery (mandatory) - specify "automatic"
* multicastGroupAddress (mandatory) - specify a valid multicast group address
* multicastGroupPort (mandatory) - specify a dedicated port for the multicast heartbeat
traffic

Configuring Manual Discovery:
Manual discovery is configured as per the following example:
<cacheManagerPeerProviderFactory class=
"net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=manual,
rmiUrls=//server1:40000/sampleCache1|//server2:40000/sampleCache1
| //server1:40000/sampleCache2|//server2:40000/sampleCache2"/>

Valid properties are:
* peerDiscovery (mandatory) - specify "manual"
* rmiUrls (mandatory) - specify a pipe separated list of rmiUrls, in the form
//hostname:port

The hostname is the hostname of the remote CacheManager peer. The port is the listening
port of the RMICacheManagerPeerListener of the remote CacheManager peer.

An alternate CacheManagerPeerProviderFactory can be used for JNDI discovery of other
CacheManagers in the cluster. Only manual discovery is supported.

For cacheManagerPeerProviderFactory specify class
net.sf.ehcache.distribution.JNDIManualRMICacheManagerPeerProviderFactoryerFactory.

Correspondingly for cacheManagerPeerListenerFactory specify class
net.sf.ehcache.distribution.JNDIRMICacheManagerPeerListenerFactoryory.

Configuring JNDI Manual Discovery:
Manual JNDI discovery is configured as per the following example:
<cacheManagerPeerProviderFactory class=
"net.sf.ehcache.distribution.JNDIManualRMICacheManagerPeerProviderFactoryerFactory"
properties="peerDiscovery=manual, stashContexts=true, stashRemoteCachePeers=true,
jndiUrls=t3//server1:40000/sampleCache1|t3//server2:40000/sampleCache1
|t3//server1:40000/sampleCache2|t3//server2:40000/sampleCache2"/>

Valid properties are:
* peerDiscovery (mandatory) - specify "manual"
* stashContexts (optional) - specify "true" or "false".  Defaults to true.
java.naming.Context objects are stashed for performance.
* stashRemoteCachePeers (optional) - specify "true" or "false".  Defaults to true.
CachePeer objects are stashed for performance.
* jndiUrls (mandatory) - specify a pipe separated list of jndiUrls,
in the form protocol//hostname:port

<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic,
multicastGroupAddress=230.0.0.1,
multicastGroupPort=4446"/>
-->

<!--
(Enable for distributed operation)

Specifies a CacheManagerPeerListenerFactory which will be used to create a
CacheManagerPeerListener, which
listens for messages from cache replicators participating in the cluster.

The attributes of cacheManagerPeerListenerFactory are:
class - a fully qualified factory class name
properties - comma separated properties having meaning only to the factory.

Ehcache comes with a built-in RMI-based distribution system. The listener component is
RMICacheManagerPeerListener which is configured using
RMICacheManagerPeerListenerFactory. It is configured as per the following example:
-->

<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="hostName=fully_qualified_hostname_or_ip,
port=40001,
socketTimeoutMillis=120000" />
<!-- 
All properties are optional. They are:
* hostName - the hostName of the host the listener is running on. Specify
where the host is multihomed and you want to control the interface over which cluster
messages are received. Defaults to the host name of the default interface if not
specified.
* port - the port the listener listens on. This defaults to a free port if not specified.
* socketTimeoutMillis - the number of ms client sockets will stay open when sending
messages to the listener. This should be long enough for the slowest message.
If not specified it defaults 120000ms.


An alternate CacheManagerPeerListenerFactory can be also be used for JNDI binding of
listeners for messages from cache replicators participating in the cluster. For
cacheManagerPeerListenerFactory specify
class net.sf.ehcache.distribution.JNDIRMICacheManagerPeerListenerFactory.
Correspondingly for cacheManagerPeerProviderFactory specify class
net.sf.ehcache.distribution.JNDIManualRMICacheManagerPeerProviderFactoryerFactory.
Properties for JNDIRMICacheManagerPeerListenerFactory are the same as
RMICacheManagerPeerListenerFactory.


<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"/>
-->
<!-- Cache configuration.

The following attributes are required.

name:
Sets the name of the cache. This is used to identify the cache. It must be unique.

maxElementsInMemory:
Sets the maximum number of objects that will be created in memory

eternal:
Sets whether elements are eternal. If eternal,  timeouts are ignored and the
element is never expired.

overflowToDisk:
Sets whether elements can overflow to disk when the in-memory cache
has reached the maxInMemory limit.

The following attributes are optional.

timeToIdleSeconds:
Sets the time to idle for an element before it expires.
i.e. The maximum amount of time between accesses before an element expires
Is only used if the element is not eternal.
Optional attribute. A value of 0 means that an Element can idle for infinity.
The default value is 0.

timeToLiveSeconds:
Sets the time to live for an element before it expires.
i.e. The maximum time between creation time and when an element expires.
Is only used if the element is not eternal.
Optional attribute. A value of 0 means that and Element can live for infinity.
The default value is 0.

diskPersistent:
Whether the disk store persists between restarts of the Virtual Machine.
The default value is false.

diskExpiryThreadIntervalSeconds:
The number of seconds between runs of the disk expiry thread. The default value
is 120 seconds.

memoryStoreEvictionPolicy:
Policy would be enforced upon reaching the maxElementsInMemory limit. Default
policy is Least Recently Used (specified as LRU). Other policies available -
First In First Out (specified as FIFO) and Less Frequently Used
(specified as LFU)

Cache elements can also contain sub elements which take the same format of a factory class
and properties. Defined sub-elements are:

* cacheEventListenerFactory - Enables registration of listeners for cache events, such as
put, remove, update, and expire.

* bootstrapCacheLoaderFactory - Specifies a BootstrapCacheLoader, which is called by a
cache on initialisation to prepopulate itself.

Each cache that will be distributed needs to set a cache event listener which replicates
messages to the other CacheManager peers. For the built-in RMI implementation this is done
by adding a cacheEventListenerFactory element of type RMICacheReplicatorFactory to each
distributed cache's configuration as per the following example:

<cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
properties="replicateAsynchronously=true,
replicatePuts=true,
replicateUpdates=true,
replicateUpdatesViaCopy=true,
replicateRemovals=true "/>

The RMICacheReplicatorFactory recognises the following properties:

* replicatePuts=true|false - whether new elements placed in a cache are
replicated to others. Defaults to true.

* replicateUpdates=true|false - whether new elements which override an
element already existing with the same key are replicated. Defaults to true.

* replicateRemovals=true - whether element removals are replicated. Defaults to true.

* replicateAsynchronously=true | false - whether replications are
asynchronous (true) or synchronous (false). Defaults to true.

* replicateUpdatesViaCopy=true | false - whether the new elements are
copied to other caches (true), or whether a remove message is sent. Defaults to true.


* asynchronousReplicationIntervalMillis=<number of milliseconds> - The asynchronous
replicator runs at a set interval of milliseconds. The default is 1000. The minimum
is 10. This property is only applicable if replicateAsynchronously=true


The RMIBootstrapCacheLoader bootstraps caches in clusters where RMICacheReplicators are
used. It is configured as per the following example:

<bootstrapCacheLoaderFactory
class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
properties="bootstrapAsynchronously=true, maximumChunkSizeBytes=5000000"/>

The RMIBootstrapCacheLoaderFactory recognises the following optional properties:

* bootstrapAsynchronously=true|false - whether the bootstrap happens in the background
after the cache has started. If false, bootstrapping must complete before the cache is
made available. The default value is true.

* maximumChunkSizeBytes=<integer> - Caches can potentially be very large, larger than the
memory limits of the VM. This property allows the bootstraper to fetched elements in
chunks. The default chunk size is 5000000 (5MB).
