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，我用一个托管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，我已经放了EJB要使用该服务，但页面测试中没有任何内容，请帮助我。

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（界面）：

 @Remote
 public interface ConsulterDossierInter {

public List<Patient> getAllPatients();
public Patient findPatient(String nom);


 }

ConsulterDossier：

@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();
}

}

PatientBean：

 @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index.xhtml：

<?xml version='1.0' encoding='UTF-8' ?>

  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。

由于

Answer 1

1-尝试使用Glassfish Payara（优于gf4） 2-为EJB使用Facade模式（优于@Remote接口） 3-用ejb替换弹簧标签
