How to save a list of value (such as strings or numbers) in cache with write through enabled?

[Zhengqingzheng]

Hi there,
In ignite cache, I can define a list of objects as one big object and save into 
cache. However, How to enable write behind or write through to database, when I 
want to write the value list into one column cell?
I know that there are jdbc mappings such as :
<bean class="org.apache.ignite.cache.store.jdbc.JdbcTypeField">
                                     <property name="databaseFieldType">
                                               <util:constant 
static-field="java.sql.Types.SMALLINT"/>
                                     </property>
                                     <property name="databaseFieldName" 
value="FIELDNUM"/>
                                     <property name="javaFieldType" 
value="java.lang.Integer"/>
                                     <property name="javaFieldName" 
value="fieldnum"/>
                            </bean>
to build the default type mappings.

How to do the same configuration with list of objects (such as strings)?
