Transaction with Spring and Mybatis

I have this mapper-config.xml.There is the DAO and the BLM fot the Game class:

<bean id="DAOGame" class="it.certimeter.nagima.dao.game.DAOGame">
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

<bean id="BLMGameTarget" class="it.certimeter.nagima.blm.game.BLMGame">
    <property name="daoGame" ref="DAOGame" />
</bean>

And the bean for the transaction:

<bean class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" id="BLMGame">
    <property name="proxyInterfaces">
        <list>
            <value>it.certimeter.nagima.blm.game.IBLMGame</value>
        </list>
    </property>
    <property name="transactionManager">
        <ref bean="transactionManager"/>
    </property>
    <property name="target">
        <ref bean="BLMGameTarget"/>
    </property>
    <property name="transactionAttributes">
        <props>
            <prop key="saveGame">PROPAGATION_REQUIRED, -it.fondsai.jeffs.core.exception.service.appl.JeffsServiceApplException</prop>
        </props>
    </property>
    <!-- <property name="anonymousAccess" value="true"/> -->
</bean>

But I have this error: nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [it.certimeter.nagima.blm.game.IBLMGame] is defined: expected single matching bean but found 2: BLMGameTarget,BLMGame

Where am I wrong??
