Interface RedisOperations<K,V>

All Known Implementing Classes:
RedisTemplate, StringRedisTemplate

public interface RedisOperations<K,V>

Interface that specified a basic set of Redis operations, implemented by RedisTemplate. Not often used but a useful option for extensibility and testability (as it can be easily mocked or stubbed).

Method Detail

execute

<T> T execute(RedisCallback<T> action)
Executes the given action within a Redis connection. Application exceptions thrown by the action object get propagated to the caller (can only be unchecked) whenever possible. Redis exceptions are transformed into appropriate DAO ones. Allows for returning a result object, that is a domain object or a collection of domain objects. Performs automatic serialization/deserialization for the given objects to and from binary data suitable for the Redis storage. Note: Callback code is not supposed to handle transactions itself! Use an appropriate transaction manager. Generally, callback code must not touch any Connection lifecycle methods, like close, to let the template do its work.

Type Parameters:
T - return type
Parameters:
action - callback object that specifies the Redis action
Returns:
a result object returned by the action or null

execute

<T> T execute(SessionCallback<T> session)
Executes a Redis session. Allows multiple operations to be executed in the same session enabling 'transactional' capabilities through multi() and watch(Collection) operations.

Type Parameters:
T - return type
Parameters:
session - session callback
Returns:
result object returned by the action or null
