縫緩存提供

Question

我想配置縫/ ehcache的從JBoss的網頁教程如下：

http://docs.jboss.org/seam/2.1.2/reference/en-US/html/cache.html

我把project.ear的ehcache.1.2.3.jar/lib目錄並注入CacheProvider，但CacheProvider始終返回null。該文檔不顯示ehcache的任何附加配置，僅針對jboss緩存。

我可能做錯了什麼，不可能這麼容易:)。

除了放在/ lib下的jar，我創建了下面的縫組件測試：

@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; 
    } 
} 
} 

感謝

添加到你的components.xml：

<components xmlns="http://jboss.com/products/seam/components" 
... 
      xmlns:cache="http://jboss.com/products/seam/cache" 
      xsi:schemaLocation= 
        "http://jboss.com/products/seam/core http://jboss.com/products/seam/core-2.1.xsd 
       http://jboss.com/products/seam/cache http://www.jboss.com/products/seam/cache-2.1.xsd"> 

... 
    <cache:eh-cache-provider/> 
... 
</components>
