Jsf p：仪表板控件状态

我有仪表板和3个小部件添加到它

<ui:define name="mainContent">
            <h:form id="dashboard" styleClass="main-page-dashboard">
                <p:dashboard id="board" model="#{serviceDashboardController.model}">
                    <p:ajax event="reorder"
                        listener="#{serviceDashboardController.handleReorder}" />

                    <p:panel id="calendar" header="#{msg.day_agenda}"
                        styleClass="calendar-dashboard dashboard-inner">
                        <ui:insert name="registry">
                            <ui:include src="/html/services/day_agenda_dashboard.xhtml" />
                        </ui:insert>
                    </p:panel>

                    <p:panel id="notary_tasks" header="#{msg.tasks}" styleClass="task-dashboard dashboard-inner">
                        <ui:insert name="notary_registry">
                            <ui:include src="/html/services/inboxMessages.xhtml" />
                        </ui:insert>
                        <p:link outcome="/html/services/inbox"
                            value="#{msg.more_not_tasks}" styleClass="enot-more-link" />
                    </p:panel>
                    <p:panel id="registry" header="#{msg.notary_registry}"
                        styleClass="registry-dashboard dashboard-inner">
                        <ui:insert name="registry">
                            <ui:include src="/html/services/notary_registry_dashboard.xhtml" />
                        </ui:insert>
                    </p:panel>
                </p:dashboard>
            </h:form>
        </ui:define>

所以我想，我应该更深入地研究

模型

。。 因此，如果有人有更多的想法，请随时……）

tomcat 7，Primefaces 5.1，Mojarra 2.2所以，答案很简单，只需要阅读一些文档就可以了。！：）

因此，可以使用JSF方法

getColumns（）保存dasboard的状态

model.addColumn(column1);
        model.addColumn(column2);
        model.addColumn(column3);

        column1.addWidget("calendar");
        column1.addWidget("notary_tasks");
        column1.addWidget("notary_registry");

List<DashboardColumn> dashboardList = model.getColumns();

public String getModelWidgets() {
        List<DashboardColumn> dashboardList = model.getColumns();
        Gson gson = new Gson();
        String toJson = gson.toJson(dashboardList);

        return toJson;
    }
