Question

I’m developing an application integrating Spring 3.1 and JSF 2. I tried to create a simple Cache using @Cacheable from Spring, thats the code from my application-context and my dao:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:cache="http://www.springframework.org/schema/cache"
    xsi:schemaLocation="  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd  
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
        http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd">

    <aop:aspectj-autoproxy />

    <cache:annotation-driven />

    <!-- generic cache manager -->
    <bean id="cacheManager" class="org.springframework.cache.support.SimpleCacheManager">
        <property name="caches">
            <set>
                <bean
                    class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean"
                    name="default" />
                <bean
                    class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean"
                    name="parametros" />
            </set>
        </property>
    </bean>

    ....

</beans>



@Override
@Cacheable(value="parametros",key="nombre")
public Parametro getByNombre(final NombreParametro nombre) {
    final Criteria criteria = super.getSession().createCriteria(
            Parametro.class);
    criteria.add(Restrictions.eq("nombre", nombre));
    return (Parametro) criteria.uniqueResult();
}

@Override
@CacheEvict(value = "parametros")
public Parametro save(final Parametro entity) {
    getHibernateTemplate().save(entity);
    return entity;
}

Then I have a Spring Component that uses the service that encapsulates this dao:

@Component("parametroUtilsBean")
public class ParametroUtilsBean implements Serializable {

    private static final Logger LOG = Logger
            .getLogger(ParametroUtilsBean.class);

    @Autowired
    IParametroService parametroService;

    public String getValorByNombre(final NombreParametro nombre) {

        final Parametro parametro = parametroService.getByNombre(nombre);
        return parametro == null ? null : parametro.getValor();
    }
}

But when I inject this component in my ManagedBean:

@ManagedProperty(value = "#{parametroUtilsBean}")
private ParametroUtilsBean parametroUtils;

public void setParametroUtils(final ParametroUtilsBean parametroUtils) {
    this.parametroUtils = parametroUtils;
}

I get the next exception:

Is the @Cacheable implementation incompatible with JSF, or am I doing something wrong? And if it’s incompatible, is there any work around?

Thanx!!

Answer 1

Sorry, turned out the exception had nothing to do with @Cacheable but with another autoimplemented AspectJ that the entity Parametro had. Without it, works perfect!
