Can I remove all elements of cache whose keys begin with the specified prefix?

For example I have 2 functions: first

Code:

public String doA(Integer userId, String someValue)

that I want to cache (with cache key "doA:" + userId + ":" + someValue), and second

Code:

public String doB(Integer userId)

that should drops cache of function "doA" for current userId (cache keys started with "doA:" + userId + ":").

I found that I can solve my problem using "getKeys*" functions and iterating over all keys searching for matches... but I thing it is wrong solution :(

Not at the moment.

But we are adding search to ehcache. It will let you do a regular expression search.

Look for the beta in November.

Are you going to add support for cache tags?

For example, method "put" will have third parameter String[] with names of tags. When we want to invalidate all caches tagged by certain tag we will call method "resetTag(String name)". Nice, isn't it?

Of course, I can write some util classes that provide this functional. But I think that it will look more correctly as part of standard functional.

The tag idea we call groups. It got done last year but has not been merged in. I am hoping to do that soon.

Please, do it :)

Hi, the Ehcache Search is now out in alpha. You can give it a go. See http://ehcache.org/documentation/search.html

Issue seems to be resolved.Please let us know if more information is required.

Please point me to the sample code or code snippet to understand the implementation.
