RE: Cache not being flushed

[Rao, Satish]

Title: Message

Hello Clinton,

 

I tried debugging the ibatis source code using WSAD. When the server starts up, I can see the control go into LRUCacheController and reading each of the statements within <flushOnExecute>. I had put breakpoints in flush() (within LRUCacheController and CachModel), but that part of the code never gets called.

 

I also tried using the <statement> tag instead of <insert> tag as follows, and that didn't work either. Also, to keep it simple, I am not using any namespaces.

 

 

<sqlMap>
        <cacheModel id ="user-cache" type= "LRU" readOnly="false" serialize="true" >
                <flushInterval hours ="24"/> 
                <flushOnExecute statement ="addEmail"/> 
                <property name ="cache-size" value= "1000"/>
        </cacheModel>
        <resultMap id ="list-users-result" class= "com.fmr.gift.strutsplus.domain.User">
                <result property ="id" column= "UID"/>
                <result property ="age" column= "AGE"/>
                <result property ="firstname" column= "FIRSTNAME"/>
                <result property ="lastname" column= "LASTNAME"/>
                <result property ="eventsJoined" column= "UID" select="getEventsJoinedByUserId" />
                <result property ="emails" column= "UID" select="getEmailsbyUserId" />
        </resultMap>
        <select id ="listUsers" resultMap= "list-users-result" cacheModel="user-cache" >
            SELECT
                UID,
                AGE,
                FIRSTNAME,
                LASTNAME
            FROM
                USERS
        </select> 
       <statement id="addEmail" parameterClass="java.util.HashMap">

            INSERT INTO

                USER_EMAILS (

                                    UID,

                                    EMAIL )

                VALUES (

                        #id#,

                        #email# )

        </statement>

</sqlMap>

It looks right....but this is the second time this has been reported in recent months.  We have about 6 unit tests just to verify cache flushing on execution, so I'm not sure what it could be.  Any chance you could debug using the ibatis source code, so you could step through the cache model? (put a breakpoint in CacheModel or in LRUCacheController...probably the flush method of either...)

Cheers,
Clinton

                FIRSTNAME,
                LASTNAME
            FROM
                USERS
        </select>
        <delete id ="removeUser" parameterClass= "java.lang.Long">
            DELETE FROM
                USERS
            WHERE
                UID = #value#
        </delete>
</sqlMap>

The caching works fine for select. But when I delete a user, I expected the cache to be be flushed because of the following entry in cache model - <flushOnExecute statement="removeUser"/> . This does not happen. When I perform removeUser operation, the user list is displayed again and shows the user id that was deleted.

Am I doing anything wrong here?
