Constructor Details

RedisKeyValueTemplate

public RedisKeyValueTemplate(RedisKeyValueAdapter adapter,
 RedisMappingContext mappingContext)

Create new RedisKeyValueTemplate.

Parameters:

mappingContext - must not be null.

Method Details

getConverter

public RedisConverter getConverter()

Obtain the underlying redis specific EntityConverter.

Returns:

never null.

getMappingContext

public RedisMappingContext getMappingContext()

Specified by:

getMappingContext in interface KeyValueOperations

Overrides:

getMappingContext in class KeyValueTemplate

find

public <T> List<T> find(RedisCallback<?> callback,
 Class<T> type)

Retrieve entities by resolving their ids and converting them into required type.
The callback provides either a single id or an Iterable of ids, used for retrieving the actual domain types and shortcuts manual retrieval and conversion of ids via RedisTemplate.

 
 List<RedisSession> sessions = template.find(new RedisCallback<Set<byte[]>>() {
   public Set<byte[]< doInRedis(RedisConnection connection) throws DataAccessException {
     return connection
       .sMembers("spring:session:sessions:securityContext.authentication.principal.username:user"
         .getBytes());
   }
 }, RedisSession.class);
 
 

Parameters:

callback - provides the to retrieve entity ids. Must not be null.

type - must not be null.

Returns:

empty list if not elements found.

 T objectToInsert)

public <T> T update(T objectToUpdate)

Specified by:

update in interface KeyValueOperations

Overrides:

update in class KeyValueTemplate

update

public <T> T update(Object id,
