Well, if you'd like to get rid of the ehcache.xml file, we'd have to go =
one step further: The current support classes for EHCache "just" specify =
the location of the ehcache.xml file in Spring config, and allow to pass =
Cache references around via IoC. We need to check how much effort =
completely driving EHCache configuration from Spring (similar to our =
LocalSessionFactoryBean does for Hibernate) would be.

Woo - this would be really cool. It would enable us to get rid of
another config file from Confluence, replacing it with yet another
Spring context file :)

RE: [Springframework-developer] EHCache support

[<viv...@ya...>]

And while we're at it, (unfortunately I'm not
volunteering just yet), it
would be nice to develop a set of interfaces in
org.springframework.cache
that can be implemented by other systems:  ehcache,
oscache, JCS.  JSR 107
spells out what the interface would look like pretty
clearly
(http://jcp.org/aboutJava/communityprocess/jsr/cacheFS.pdf),
but there are
no standard implementations of this.  Every
implementation of the caching
system seems to support it loosely, with common
methods, but there is not a
common interface, so users are always tied to one
particular caching
product.  

Spring has provided this kind of common interface for
a number of other
areas, and caching would be great to add to it.  The
jcache
(jcache.sourceforge.net) project seems to stay closest
to the original JSR.

Dmitriy,

This looks awesome to me - put it in the core! +1! 

I can feel a cachingSubsystemContext.xml coming on :)

You could send them to me, I will check them into the sandbox, then we 
review/collaborate and see if they could make 1.1.2 (mid November)

1.1.1 is scheduled for release tonight.

Re: [Springframework-developer] EHCache support

[Mike Cannon-B. <mca...@gm...>]

Mate,

I just looked at the code Dmitriy has written, and from my knowledge
of EHCache (incidentally often referred to as Canadian cache in the
office, or just "cache, eh?") it would be completely trivial (ie a 2
minute task :)) to add this?

The EhCacheManagerFactoryBean already does not require an ehcache.xml
file, it will use one if provided with one - otherwise it will just
create a blank CacheManager. So this part works fine.

The only thing to add would be a way to create new caches.=20

In code, this is easy to do:

Cache cache =3D new Cache("MyCache", 1000, true, false, 500, 200);
manager.addCache(cache);

There are only 6 properties for every cache (as above - cache name,
max size, overflow to disk, eternal, time to live and time to idle).
Why not just add these as setters to EhCacheFactoryBean, and have that
create the cache and register it with the referenced CacheManager?

What else would be required?

Cheers,
Mike

Re: [Springframework-developer] EHCache support

[Dmitriy K. <dko...@ru...>]

Mike, everyone,

I've refined the EHCache support by allowing configuring named cache 
regions via EhCacheManagerFactoryBean's properties and not requiring 
ehcache.xml file anymore (if desired).

The behavior is like this:
1) configure EhCacheManagerFactoryBean with "configLocation" (optional) 
If "configLocation" is not specified it creates a "blank" CacheManager 
(with no caches defined).
2) Configure any number of named Caches (providing  cache name and 
CacheManager as bean references) and optionally providing cache 
properties (some or all or none - all the cache properties will have a 
sensible default value) If the named cache is pre-configured in cache 
config descriptor it will be used, ignoring any cache bean properties, 
else the new Cache instance will be created and added to a CacheManager 
for later retrieveval. Some config examples:

<!-- Configure CacheManager from specified config location -->
<bean id="cacheManager" 
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
    <property 
name="configLocation"><value>WEB-INF/ehcache.xml</value></property>
</bean>

<!-- Configure myCache1 region overriding the default properties.  If 
myCache1 is found in ehcache.xml, the properties will be ignored -->
<bean id="myCache1" 
class="org.springframework.cache.ehcache.EhCacheFactoryBean">
        <property name="cacheManager"><ref local="cacheManager"/></property>
        <property name="cacheName"><value>myCache1</value></property>
        <property name="maxElementsInMemory"><value>20000</value></property>
        <property name="overflowToDisk"><value>true</value></property>
        <property name="eternal"><value>false</value></property>
        <property name="timeToLive"><value>600</value></property>
        <property name="timeToIdle"><value>500</value></property>
</bean>

<!-- Configure myCache2 region overriding maxElementsInMemory property.  
If myCache2 is found in ehcache.xml, the properties will be ignored -->
<bean id="myCache3" 
class="org.springframework.cache.ehcache.EhCacheFactoryBean">
        <property name="cacheManager"><ref local="cacheManager"/></property>
        <property name="cacheName"><value>myCache2</value></property>
        <property 
name="maxElementsInMemory"><value>1230000</value></property>
</bean>

The default properties are:
    - maxElementsInMemory: 10000
    - overflowToDisk: true
    - eternal: false
    - timeToLive: 120
    - timeToIdle: 120

Does this cover basic use cases? If so, I'll be happy to commit this to 
the main source tree before 1.1.1 Let me know.

Regards,
Dmitriy.

We need to check how much effort completely driving EHCache configuration from Spring (similar to our LocalSessionFactoryBean does for Hibernate) would be.

Dmitriy,

This looks awesome to me - put it in the core! +1!=20

I can feel a cachingSubsystemContext.xml coming on :)
