我有兩個jsf控制器說ControllerA和ControllerB。兩者都在Session範圍內。我想從ControllerA調用ControllerB中的create方法。我用@ManagedProperty到do.But它似乎並沒有工作使用@ManagedProperty調用受管Bean之間的方法
@ManagedBean(name = "manageAccountController")
@SessionScoped
public class ControllerA implements Serializable{
public void accountSetup()
{
@ManagedProperty(value="#{controllerB}")
private ControllerB details;
System.out.print("Inside controller ");
details.create();
}
}
public String prepareCreate() {
System.out.print("Inside prepare create ");
current = new ControllerB();
selectedItemIndex = -1;
return "Create";
}
public String create() {
try {
System.out.print("Inside create ");
getJpaController().create(current);
JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("Created"));
return prepareCreate();
} catch (Exception e) {
JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));
return null;
}
}
我不能調用controllerB.The控制檯顯示的方法，下面的錯誤
