Question

我正在尝试使用PrimeFaces框架创建过滤数据表。我的问题是显示数据表但过滤选项不起作用，请帮助！

我的page.xhtml看起来像：

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:p="http://primefaces.org/ui"
      xmlns:f="http://java.sun.com/jsf/core">
    <ui:composition>
        <h5>
            <h:form>
                <p:dataTable var="student" value="#{studentWizard.students}" widgetVar="studentTable" emptyMessage="Aucun élève trouvé" id="tableStudent" filteredValue="#{studentWizard.filteredStudents}" >

                    <f:facet name="header">
                        <p:outputPanel>
                            <h:outputText value="Chercher tous les champs:" />
                            <p:inputText id="globalFilter" onkeyup="studentTable.filter()" style="width:150px" placeholder="Entrer le mot-clé"/>
                        </p:outputPanel>
                    </f:facet>

                    <p:column filterBy="#{student.studentCode}"  headerText="Code de l'élève" filterMatchMode="contains">
                        <h:outputText value="#{student.studentCode}"/>
                    </p:column>

                    <p:column filterBy="#{student.firstName}" headerText="Prénom" filterMatchMode="contains">
                        <h:outputText value="#{student.firstName}"/>
                    </p:column>

                    <p:column filterBy="#{student.lastName}" headerText="Nom" filterMatchMode="contains">
                        <h:outputText value="#{student.lastName}"/>
                    </p:column>

                    <p:column headerText="Modifier" >
                        <p:commandButton value="Modifier" type="submit"  ajax="false"  icon="ui-icon-update"/>
                    </p:column>
                </p:dataTable>
            </h:form>
        </h5>
    </ui:composition>
</html>

和我的Java Bean：

@ManagedBean(name="studentWizard")
@Component
@ViewScoped
public class StudentWizard implements Serializable {

    public StudentWizard() {}

    private static final long serialVersionUID = 1L;

    private Student student;
    private List<Student> students;
    private List<Student> filteredStudents;

    @PostConstruct
    public void init() {
        students = getAllStudent();
    }

    public List<Student> getFilteredStudents() {
        return filteredStudents;
    }

    public void setFilteredStudents(List<Student> filteredStudents) {
        this.filteredStudents = filteredStudents;
    }

    @Autowired
    private StudentManager studentManager;

    public void setStudentManager(StudentManager studentManager) {
        this.studentManager = studentManager;
    }

    public Student getstudent() {
        return student;
    }

    public StudentManager getStudentManager() {
        return studentManager;
    }

    public void setstudent(Student student) {
        this.student = student;
    }

    public void save() {
        studentManager.saveStudent(student);
        student = new Student();

    }

    public List<Student> getAllStudent() {
        return studentManager.getAllStudent();
    }

    public Student getStudentById(int id) {
        return studentManager.getStudentById(id);
    }

    public List<Student> getStudents() {
        return students;
    }

    public void setStudents(List<Student> students) {
        this.students = students;
    }
}

p：dataTable过滤不适用于模板
