Question

我在GlassFish 3.1.2上遇到泛型和CDI / WELD问题。我有这些课程：

这是一个抽象bean，它持有对JPA实体的引用。

public abstract class AbstractViewBean<T extends Serializable> implements ISelectableBean {

    ...        

    private T viewObject;

    ...
}

然后我有我的JSF bean / pages的抽象类，我想要注入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.Validator.validateInjectionPoint(Validator.java:311)
at org.jboss.weld.bootstrap.Validator.validateInjectionPoint(Validator.java:280)
at org.jboss.weld.bootstrap.Validator.validateBean(Validator.java:143)
at org.jboss.weld.bootstrap.Validator.validateRIBean(Validator.java:163)
at org.jboss.weld.bootstrap.Validator.validateBeans(Validator.java:382)
at org.jboss.weld.bootstrap.Validator.validateDeployment(Validator.java:367)
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;
    ...
}

Everithing工作正常。但为什么呢？

感谢。

修改

我将weld-osgi-bundle.jar的WELD版本更新为1.1.11，但没有效果。

使用CDI / WELD注入通用数据模型
