PrimeFaces Lazydatamodel没有显示任何记录

Question

这是关于PrimeFaces延迟加载

<h:head>
    <title>data table with pagination</title>
</h:head>
<h:body>
    <h3>datatable with pagination</h3>
    <p:dataTable var="lazemp" value="#{lazy.lazy1}" paginator="true" rows="8"
                 paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
                 rowsPerPageTemplate="5,8,11" lazy="true">
        <p:column headerText="ID">
            <h:outputText value="#{lazemp.id}"/>
        </p:column>
        <p:column headerText="NAME">
            <h:outputText value="#{lazemp.name}"/>
        </p:column>

        <p:column headerText="SPECIFICATION">
            <h:outputText value="#{lazemp.specification}"/>
        </p:column>
    </p:dataTable>

这里必须从这个java文件中获取数据。

@ManagedBean(name = "lazy")
@RequestScoped
public class Lazyload {

    private LazyDataModel<Employee> lazy1;

    public LazyDataModel<Employee> getLazy1() {
        return lazy1;
    }

    public void setLazy(LazyDataModel<Employee> lazy1) {
        this.lazy1 = lazy1;
    }

    @PostConstruct
    public void init() {
        lazy1 = new LazyDataModel<Employee>() {

            public ArrayList<Employee> load(int first, int pageSize, String sortField, boolean sortOrder, Map<String, String> filters) {

        };
        lazy1.setRowCount(15);
    }
}

在运行时只获取没有数据的列文本，显示没有任何记录存在，我被任何帮助都会受到赞赏
