我如何在JSF中使用会话属性（这样的属性是通过下面的第三方HttpServlet获得的），这样我就可以向用户显示它，并将它与表单中的其他值一起存储？
HttpServlet（通过第三方登录资源远程获取的对象）：
public class ServletLogar extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException, Exception {
response.setContentType("text/html;charset=UTF-8");
String req = request.getParameter("pag");
IntranetAuth intranetAuth = new IntranetAuth();
if (!intranetAuth.isAuth(request, response)) {
response.sendRedirect(intranetAuth.urlLoginPage);
return;
}
UserVO userVO = intranetAuth.usuerVO;
if (intranetAuth.isAuth(request, response, req, req) {
BeanLogin beanLogin = new BeanLogin(); // a POJO
beanLogin.setxUserID(userVO.getUserID());
request.getSession().setAttribute("xUserID", userVO.getUserID());
response.sendRedirect(req);
}
//doGet and doPost ommited
}
JSF（形式）：
<!-- [...] -->
<h:form id="ViagensCreateForm">
<h:panelGroup id="display">
<p:panelGrid columns="2">
<p:outputLabel value="Type the Reason:" for="reason" />
<p:inputText id="reason" value="#{viagensController.selected.reason}" />
<p:outputLabel value="UserID (the sessionAttribute):" for="userID" />
<p:inputText id="userID" value="#{SessionScope.userID}" title="userID" />
</p:panelGrid>
<p:commandButton actionListener="#{viagensController.saveNew}" value="Save" />
</h:panelGroup>
</h:form>
ViagensController:
@Named(value = "viagensController")
@ViewScoped
public class ViagensController extends AbstractController<Viagens> implements Serializable {//generics:passing JPA Entity class, where the 'reason' in JSF is defined
public ViagensController() {
super(Viagens.class);
}
}
AbstractController（对于上面JSF中选择的和其他方法）：
public abstract class AbstractController<T> {
@Inject
private AbstractFacade<T> ejbFacade;
private Class<T> itemClass;
private T selected;
private Collection<T> items;
private enum PersistAction {
CREATE,
DELETE,
UPDATE
}
public AbstractController() {
}
public AbstractController(Class<T> itemClass) {
this.itemClass = itemClass;
}
public T getSelected() {
return selected;
}
// Pass in the currently selected item
public void setSelected(T selected) {
this.selected = selected;
}
protected void setEmbeddableKeys() {
}
protected void initializeEmbeddableKey() {
}
public Collection<T> getItems() {
if (items == null) {
items = this.ejbFacade.findAll();
}
return items;
}
// Pass in collection of items
public void setItems(Collection<T> items) {
this.items = items;
}
// Apply changes to an existing item to the data layer.
public void save(ActionEvent event) {
String msg = ResourceBundle.getBundle("/viagensBundle").getString(itemClass.getSimpleName() + "Updated");
persist(PersistAction.UPDATE, msg);
}
// Store a new item in the data layer.
public void saveNew(ActionEvent event) {
String msg = ResourceBundle.getBundle("/viagensBundle").getString(itemClass.getSimpleName() + "Created");
persist(PersistAction.CREATE, msg);
if (!isValidationFailed()) {
items = null; // Invalidate list of items to trigger re-query.
}
}
public void delete(ActionEvent event) {/*implementations ommited*/ }
private void persist(PersistAction persistAction, String successMessage) {
if (selected != null) {
this.setEmbeddableKeys();
try {
if (persistAction != PersistAction.DELETE) {
this.ejbFacade.edit(selected);
} else {
this.ejbFacade.remove(selected);
}
JsfUtil.addSuccessMessage(successMessage);
} catch (EJBException ex) {
String msg = "";
Throwable cause = JsfUtil.getRootCause(ex.getCause());
if (cause != null) {
if (cause instanceof ConstraintViolationException) {
ConstraintViolationException excp = (ConstraintViolationException) cause;
for (ConstraintViolation s : excp.getConstraintViolations()) {
JsfUtil.addErrorMessage(s.getMessage());
}
} else {
msg = cause.getLocalizedMessage();
if (msg.length() > 0) {
JsfUtil.addErrorMessage(msg);
} else {
JsfUtil.addErrorMessage(ex, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));
}
}
}
} catch (Exception ex) {
Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, ex);
JsfUtil.addErrorMessage(ex, ResourceBundle.getBundle("/viagensBundle").getString("PersistenceErrorOccured"));
}
}
}
// Creates a new instance of an underlying entity and assigns it to Selected property.
public T prepareCreate(ActionEvent event) {
T newItem;
try {
newItem = itemClass.newInstance();
this.selected = newItem;
initializeEmbeddableKey();
return newItem;
} catch (InstantiationException ex) {
Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, ex);
}
return null;
}
// Inform the user interface whether any validation error exist on a page.
public boolean isValidationFailed() {
return JsfUtil.isValidationFailed();
}
// Retrieve all messages as a String to be displayed on the page.
public String getComponentMessages(String clientComponent, String defaultMessage) {
return JsfUtil.getComponentMessages(clientComponent, defaultMessage);
}
}
Viagens立面：
@Stateless
public class ViagensFacade extends AbstractFacade<Viagens> {
@PersistenceContext(unitName = "viagensPU")
private EntityManager em;
@Override
protected EntityManager getEntityManager() {
return em;
}
public ViagensFacade() {
super(Viagens.class);
}
}
抽象立面：
public abstract class AbstractFacade<T> {
private Class<T> entityClass;
public AbstractFacade(Class<T> entityClass) {
this.entityClass = entityClass;
}
protected abstract EntityManager getEntityManager();
public void create(T entity) {
getEntityManager().persist(entity);
}
public void edit(T entity) {
getEntityManager().merge(entity);
}
public void remove(T entity) {
getEntityManager().remove(getEntityManager().merge(entity));
}
public T find(Object id) {{ /*impl. ommited*/ }
public List<T> findAll() {{ /*impl. ommited*/ }
public List<T> findRange(int[] range) { /*impl. ommited*/ }
public int count() { /*impl. ommited*/ }
}
提前谢谢。
更新代码：
package br.com.bb.upb.diage.viagens.beans;
import java.io.Serializable;
import javax.annotation.PostConstruct;
//import javax.faces.bean.SessionScoped; --> Thank you, John Ament !!
import javax.enterprise.context.SessionScoped;
import javax.faces.context.FacesContext;
import javax.inject.Named;
@Named(value = "userBean")
@SessionScoped
public class UserBean implements Serializable {
private bean_login myUser;
public bean_login getMyUser() {
return myUser;
}
public void setMyUser(bean_login myUser) {
this.myUser = myUser;
}
@PostConstruct
public void init() {
String uid = FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("xChave").toString();
myUser = new bean_login();
myUser.setxChave(uid);
System.out.print("from init:" + myUser.toString());
}
}
在我的JSF中：
<p:outputLabel value="UserID (the sessionAttribute):" for="userID" />
<p:inputText id="userID" value="#{userBean.myUser.xChave}" title="userID" />
<p:outputLabel value="Type the Reason:" for="reason" />
<p:inputText id="reason" value="#{viagensController.selected.reason}" />
错误：
