We now serialize Enum values using their name (Enum.name()) instead of using their string representation (Enum.toString()). toString can be customized in Enums to no longer report their name but a different value. A customized value cannot be used to reinstantiate the Enum value, only its name.
This change affects serialization and will only affect new/updated values. Stored values with a customized toString representation still can't be deserialized until they were updated in Redis.

We now consider the element expiry when retrieving cache elements with a value loader. Previously, all cache elements that were cached using `@Cacheable(sync=true)` or used `RedisCache.get(Object, Callable)` directly were considered eternal without setting a TTL.

Remove pExpireAt workaround that can lead to NullPointerException if called within a transaction/pipeline. Calls to expire(…) with a timeout greater Integer.MAX_VALUE are delegated to pExpire converting seconds to milliseconds.

Run expiry tests only when executing long-running tests. Guard RedisConnectionFactory against multiple initializations. Synchronize key expiry. Remove unused code. Extend years in license header.

We now no longer rely on ApplicationEvents captured in the RedisKeyValueAdapter for performing cleanup operations for expired keys, but do this along with the phantom key removal. This removes a flaw when initializing a non repository related KeyspaceEventListener publishing events that actually are unrelated to the Adapter.
Additionally upgraded test infrastructure to utilize Redis 3.2.6 with disabled protected-mode and enabled keyspace-events.

Extend JavaDoc documentation for Command/Connection/Operation interfaces. Align method ordering in operation interfaces with connection/commands interfaces.
Apply client name to Sentinel and unpooled connections if set. Add ticket references to JavaDoc. Add tests. Fix existing JavaDoc letter casing and punctuation. Rearrange isClusterAware/isRedisSentinelAware methods.
Original pull request: #219.
Motivation:
JedisConnectionFactory should support setting clientName for Jedis connections
so to improve troubleshooting.
Result:
Easier to troubleshooting with connection name.

Improve javadoc. Replace static method imports with qualified method calls. Refactor duplicate RedisCacheKey construction into own method. Fix formatting.

Store `NullValue` placeholders when null value caching is allowed. Remove cache values when null value caching is disabled and the value loader returns a `null` value.
Original pull request: #221.
We now support caching `null` values in `RedisCache` by storing a dedicated `NullValue` reference as a placeholder. To enable this feature please set up `RedisCacheManager` accordingly and make sure the used `RedisSerializer` is capable of dealing the `NullValue` type.
Both the `JdkSerializationRedisSerializer` and the `GenericJackson2JsonRedisSerializer` support this out of the box.

RedisCache now expires keys using putIfAbsent if the key was set. Previously, the key was only expired if the value was already present and the value matched the value stored inside of Redis.
Original Pull Request: #224
We now allow usage of @GeoIndexed to mark GeoLocation or Point properties as candidates for secondary index creation. Non null values will be included in GEOADD command as follows:
GEOADD keyspace:property-path point.x point.y entity-id
@GeoIndexed can be used on top level as well as on nested properties.
class Person {
@Id String id;
String firstname, lastname;
Address hometown;
}
class Address {
String city, street, housenumber;
@GeoIndexed Point location;
}
The above allows us to derive geospatial queries from a given method using NEAR and WITHIN keywords like:
interface PersonRepository extends CrudRepository<Person, String> {
List<Person> findByAddressLocationNear(Point point, Distance distance);
List<Person> findByAddressLocationWithin(Circle circle);
}
Partial updates on the Point itself also trigger an index refresh operation. So it is possible to alter existing entities via:
template.save(new PartialUpdate<Person>("1", Person.class).set("address.location", new Point(17, 18));

We now make sure to count records without using criteria when derived criteria is empty. This allows usage of declared query methods using `Pageable` without criteria like `findBy(Pageable page)`.
Original Pull Request: #220
We now make sure to pipe finder queries without any criteria to the according find all method. This allows usage of `PagingAndSortingRepository.findAllBy(Pageable page)` as well as finders without any criteria like `findTop3By()`.

SCAN, SSCAN, HSCAN and ZSCAN now reference a dedicated connection that is bound to the Cursor. This allows creation of multiple cursors for different threads without the risk of potentially sharing a single connection. As before the caller is responsible for closing the Cursor correctly after usage.
