管理 Bean JSF 项目

Question

我正在用JSF做一个项目，为了测试我的项目，我做了一个接口，我使用托管Bean在一个简单的页面xhtml中显示数据库中定义的实体的内容，我已经让EJB使用服务，但是页面测试中没有出现任何东西，页面你能帮我吗？

实体：

@Entity
@NamedQuery(name="Patient.findAll", query="SELECT p FROM Patient p")
public class Patient implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name="id_patient")
private int idPatient;
private String adresse;
@Temporal(TemporalType.TIMESTAMP)
@Column(name="date_naissance")
private Date dateNaissance;
private String email;
@Column(name="groupe_sanguin")
private String groupeSanguin;
private String login;
private String nom;
@Column(name="num_secu_sociale")
private String numSecuSociale;
private String password;
private String prenom;
@Column(name="regime_assurance")
private String regimeAssurance;
private String tel;
public Patient() {
}
public int getIdPatient() {
    return this.idPatient;
}
public void setIdPatient(int idPatient) {
    this.idPatient = idPatient;
}
public String getAdresse() {
    return this.adresse;
}
public void setAdresse(String adresse) {
    this.adresse = adresse;
}
public Date getDateNaissance() {
    return this.dateNaissance;
}
public void setDateNaissance(Date dateNaissance) {
    this.dateNaissance = dateNaissance;
}
public String getEmail() {
    return this.email;
}
public void setEmail(String email) {
    this.email = email;
}
public String getGroupeSanguin() {
    return this.groupeSanguin;
}
public void setGroupeSanguin(String groupeSanguin) {
    this.groupeSanguin = groupeSanguin;
}
public String getLogin() {
    return this.login;
}
public void setLogin(String login) {
    this.login = login;
}
public String getNom() {
    return this.nom;
}
public void setNom(String nom) {
    this.nom = nom;
}
public String getNumSecuSociale() {
    return this.numSecuSociale;
}
public void setNumSecuSociale(String numSecuSociale) {
    this.numSecuSociale = numSecuSociale;
}
public String getPassword() {
    return this.password;
}
public void setPassword(String password) {
    this.password = password;
}
public String getPrenom() {
    return this.prenom;
}
public void setPrenom(String prenom) {
    this.prenom = prenom;
}
public String getRegimeAssurance() {
    return this.regimeAssurance;
}
public void setRegimeAssurance(String regimeAssurance) {
    this.regimeAssurance = regimeAssurance;
}
public String getTel() {
    return this.tel;
}
@Override
public String toString() {
    return "Patient [idPatient=" + idPatient + ", adresse=" + adresse + ", dateNaissance=" + dateNaissance
            + ", email=" + email + ", groupeSanguin=" + groupeSanguin + ", login=" + login + ", nom=" + nom
            + ", numSecuSociale=" + numSecuSociale + ", password=" + password + ", prenom=" + prenom
            + ", regimeAssurance=" + regimeAssurance + ", tel=" + tel + "]";
}
public void setTel(String tel) {
    this.tel = tel;
}
}

ConsulterDossierInter （interface）：

 @Remote
 public interface ConsulterDossierInter {
public List<Patient> getAllPatients();
public Patient findPatient(String nom);

 }

咨询档案 ：

@Stateless
public class ConsulterDossier implements ConsulterDossierInter {

@PersistenceContext
private EntityManager em;

public ConsulterDossier() {
    // TODO Auto-generated constructor stub
}

@SuppressWarnings("unchecked")
@Override
public List<Patient> getAllPatients() {
    // TODO Auto-generated method stub
    Query query=em.createQuery("SELECT p FROM Patient p");
    return query.getResultList();
}
@Override
public Patient findPatient(String nom) {
    Query q=em.createQuery("SELECT p FROM Patient p WHERE p.nom=:nom");
    q.setParameter("nom",nom);
    return  (Patient) q.getSingleResult();
}
}

患者豆 ：

 @ManagedBean
 @ViewScoped
 public class PatientBean implements Serializable{
 /**
 * 
 */
private static final long serialVersionUID = 1L;
@EJB
 ConsulterDossierInter consult_dossier;
private Patient patient= new Patient();
private List<Patient> list_patient=new  ArrayList<Patient>();
public List<Patient> listePatient(){
    list_patient=consult_dossier.getAllPatients();
    return list_patient;
}
@PostConstruct  
public void init(){
    list_patient=consult_dossier.getAllPatients();
}
public PatientBean() {
    // TODO Auto-generated constructor stub
}
public ConsulterDossierInter getConsult_dossier() {
    return consult_dossier;
}
public void setConsult_dossier(ConsulterDossierInter consult_dossier) {
    this.consult_dossier = consult_dossier;
}
public Patient getPatient() {
    return patient;
}
public void setPatient(Patient patient) {
    this.patient = patient;
}
public List<Patient> getList_patient() {
    return list_patient;
}
public void setList_patient(List<Patient> list_patient) {
    this.list_patient = list_patient;
}
}

最后是 XHTML 接口索引.xhtml

：

  xmlns:f="http://xmlns.jcp.org/jsf/core">

<h:head>
 <title>
   test
   </title>
</h:head>
 <h:body>
    <h1>List of books</h1>
<h:dataTable id="booklist" 
             value="#{patientBean.list_patient}" 
             var="book" 
             border="1">
  <h:column>
    <f:facet name="header">
      <h:outputText value="Title"/>
    </f:facet>
    <h:outputText value="#{book.idPatient}"/>
  </h:column>
</h:dataTable>
  <hr/>
  <h:outputText value="TP3 from Beginning Java EE 7" style="font-style:    italic"/>
  </h:body>
  </html>

顺便说一下，我使用GlassFish服务器4。

谢谢

Answer 1

1-尝试使用Glassfish Payara（比gf4更好）2-为您的EJB使用外观模式（比@Remote界面更好）3-用EJB替换弹簧标签
