Phillip Webb 8c2ace33cb Support 'unless' expression for cache veto Allow @Cachable, @CachePut and equivalent XML configuration to provide a SpEL expression that can be used to veto putting an item into the cache. Unlike 'condition' the 'unless' parameter is evaluated after the method has been called and can therefore reference the #result. For example: @Cacheable(value="book", condition="#name.length < 32", unless="#result.hardback") This commit also allows #result to be referenced from @CacheEvict expressions as long as 'beforeInvocation' is false.

Phillip Webb 8c2ace33cb Support 'unless' expression for cache veto

Allow @Cachable, @CachePut and equivalent XML configuration to provide
a SpEL expression that can be used to veto putting an item into the
cache. Unlike 'condition' the 'unless' parameter is evaluated after
the method has been called and can therefore reference the #result.

For example:

    @Cacheable(value="book",
        condition="#name.length < 32",
        unless="#result.hardback")

This commit also allows #result to be referenced from @CacheEvict
expressions as long as 'beforeInvocation' is false.
