我正在尝试按照jboss页面的教程配置seam / ehcache:
http://docs.jboss.org/seam/2.1.2/reference/en-US/html/cache.html
我将ehcache.1.2.3.jar放在project.ear / lib中并注入了CacheProvider,但CacheProvider总是返回null。该文档没有显示ehcache的任何附加配置,仅适用于jboss缓存。
我可能做错了,不可能这么简单:)。
除了将jar放入/ lib之外,我创建了以下的seam组件来测试:
@Scope(ScopeType.SESSION)
@Name("cacheBean")
public class CacheSeamBean implements java.io.Serializable {
@In(required=false, create=true)
private EntityManager em;
@Logger
private Log log;
@In
private Events events;
@In CacheProvider cacheProvider;
Boolean blLoaded = Boolean.FALSE;
@Create
public void buscar() {
if (!blLoaded){
List<Parametro> lstParametro = em.createQuery("select p from Parametro p").getResultList();
for (Parametro parametro : lstParametro){
cacheProvider.put(parametro.getCodigo(), parametro.getValor());
}
blLoaded= Boolean.TRUE;
}
}
}
