RedisStoreMessageSource

public RedisStoreMessageSource(RedisTemplate<String,?> redisTemplate,
 Expression keyExpression)

Create an instance with the provided RedisTemplate and SpEL expression which should resolve to a 'key' name of the collection to be used. It assumes that RedisTemplate is fully initialized and ready to be used. The 'keyExpression' will be evaluated on every call to the AbstractMessageSource.receive() method.

Parameters:

redisTemplate - The Redis template.

keyExpression - The key expression.

RedisStoreMessageSource

public RedisStoreMessageSource(RedisConnectionFactory connectionFactory,
 Expression keyExpression)

Create an instance with the provided RedisConnectionFactory and SpEL expression which should resolve to a 'key' name of the collection to be used. It will create and initialize an instance of StringRedisTemplate that uses StringRedisSerializer for all serialization. The 'keyExpression' will be evaluated on every call to the AbstractMessageSource.receive() method.

Parameters:

connectionFactory - The connection factory.

keyExpression - The key expression.

Return a Message with the view into a RedisStore identified by keyExpression

Specified by:

doReceive in class AbstractMessageSource<RedisStore>

Returns:

The value returned.
