我对 GlassFish 3.1.2 上的泛型和 CDI/WELD 有疑问。我有这些课程:
这是持有对 JPA 实体的引用的抽象 bean。
public abstract class AbstractViewBean<T extends Serializable> implements ISelectableBean {
...
private T viewObject;
...
}
然后我有我的 JSF bean/页面的抽象类,我想在其中注入 TableLazyDataModel
public abstract class AbstractListPageAction<T extends AbstractViewBean<K>, K extends
Serializable> {
...
@Inject
private TableLazyDataModel<T, K> dataModel;
...
}
TableLazyDataModel:
public class TableLazyDataModel<T extends AbstractViewBean<K>, K extends Serializable>
extends LazyDataModel<T> {
...
}
如果我想部署应用程序,我会得到:
org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [TableLazyDataModel<UserViewBean, CcalPracovnik>] with qualifiers [@Default] at injection point [[field] @Inject private cz.wf.ui.component.page.AbstractListPageAction.dataModel]

at org.jboss.weld.bootstrap.WeldBootstrap.validateBeans(WeldBootstrap.java:379)
at org.glassfish.weld.WeldDeployer.event(WeldDeployer.java:199)
如果我从 AbstractViewBean 和其他类中删除extends Serializable :
public abstract class AbstractViewBean<T> implements ISelectableBean {
...
private T viewObject;
...
}
public abstract class AbstractListPageAction<T extends AbstractViewBean<K>, K> {
...
@Inject
private TableLazyDataModel<T, K> dataModel;
...
}
一切正常。但为什么?
谢谢。
编辑:
我将weld-osgi-bundle.jar 的WELD 版本更新为1.1.11,但没有任何效果。
