我正在尝试使用 ManagedProperty:

从这里

@ManagedBean(name = "SelectionBean")
@SessionScoped
public class TableSelectionBean implements Serializable {
    private String selectionMode = "single";
    private Collection<Object> selection;
    private List<MonitoringData> monitoringData;
    private List<MonitoringData> selectionMonitoringData;

到这里:

@ManagedBean(name="ActionBean")
@SessionScoped
public class MonitoringActionBean implements Serializable {
    private ThreadPoolExecutor executor;
    @ManagedProperty(value="{SelectionBean.selectionMonitoringData}")
    private List<MonitoringData> selectedMonitoring;

我收到以下错误消息:

com.sun.faces.mgbean.ManagedBeanCreationException:无法为托管 bean ActionBean 设置属性 selectedMonitoring ... 原因:java.lang.IllegalArgumentException:无法将 java.lang.String 类型的 {SelectionBean.selectionMonitoringData} 转换为接口 java。实用程序列表

知道为什么它不起作用吗?

您似乎忘记了标签:

@ManagedProperty(value="{SelectionBean.selectionMonitoringData}")

应该:

@ManagedProperty(value="#{SelectionBean.selectionMonitoringData}")
