救生筏搜索容器分页问题

Question

这是我的Liferay搜索容器代码：

MVC:BigInteger leaveTotalCount;
        ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);
        PortletURL iteratorURL = PortletURLFactoryUtil.create(request, themeDisplay.getPortletDisplay().getId(),
                themeDisplay.getPlid(), PortletRequest.RENDER_PHASE);
        SearchContainer<LeaveDetailsWrapper> searchContainer = null;
        searchContainer = new SearchContainer<>(request, null, null, SearchContainer.DEFAULT_CUR_PARAM,
                SearchContainer.DEFAULT_DELTA, iteratorURL, null, LmsLeaveDashboardConstant.BLANK_STRING);
        List<LeaveDetailsWrapper> leaveDetails;
        try {
            searchContainer.setDeltaConfigurable(true);
            leaveDetails = leaveLocalService.getLeaveDetails(null, null, null, null,
                    LmsLeaveDashboardUtils.getEmpCode(request), searchContainer.getStart(), searchContainer.getEnd());
            log.info(leaveDetails);
            leaveTotalCount = leaveLocalService.getLeaveDetailsCount(null, null, null, null,
                    LmsLeaveDashboardUtils.getEmpCode(request), -1, -1);
            searchContainer.setEmptyResultsMessage("No Data Found..!");
            searchContainer.setTotal(leaveTotalCount.intValue());
            searchContainer.setIteratorURL(iteratorURL);

            searchContainer.setResults(leaveDetails);
        } catch (Exception e) {
            log.error("ERROR:IntrahrmsLmsLeaveDashboardWebPortlet leaveSearchContianer" + e);
        }
        return searchContainer;

jsp:

    <liferay-ui:search-container searchContainer="${leaveInfoContainer}" iteratorURL="${iteratorURL}">
            <liferay-ui:search-container-results
                results="${leaveInfoContainer.getResults()}" />

            <liferay-ui:search-container-row
                className="com.intrahrms.lms.service.leavecustom.model.LeaveDetailsWrapper"
                modelVar="LeaveDetails">

                <liferay-ui:search-container-column-text
                    value="${LeaveDetails.leaveTypeName} Leave " name="Leave Type" />
                <liferay-ui:search-container-column-text name="From Date">
                    <fmt:formatDate pattern="dd/MM/yyyy"
                        value="${LeaveDetails.fromDate}" type="date" />
                </liferay-ui:search-container-column-text>

                <liferay-ui:search-container-column-text name="To Date">
                    <fmt:formatDate pattern="dd/MM/yyyy" value="${LeaveDetails.toDate}"
                        type="date" />
                </liferay-ui:search-container-column-text>

                <liferay-ui:search-container-column-text
                    value="${LeaveDetails.totalDays}" name="Total Leave Days" />

                <liferay-ui:search-container-column-text name="Applied Date">
                    <fmt:formatDate pattern="dd/MM/yyyy"
                        value="${LeaveDetails.appliedDate}" type="date" />
                </liferay-ui:search-container-column-text>


                <liferay-ui:search-container-column-text
                    value="${LeaveDetails.leaveStatus} " name="Status" />

                <liferay-ui:search-container-column-text
                    value="${LeaveDetails.projectManagerId}" name="Reporting Manager" />


                <liferay-ui:search-container-column-jsp path="/action.jsp"
                    align="center" />

            </liferay-ui:search-container-row>

            <liferay-ui:search-iterator markupView="lexicon" />
        </liferay-ui:search-container>

问题是，当我更改分页或增量时，它会给我整个记录，而不是过滤器记录。

您的搜索容器似乎做了正确的事情，如：

leaveDetails = leaveLocalService.getLeaveDetails(null, null, null, null,
                    LmsLeaveDashboardUtils.getEmpCode(request), searchContainer.getStart(), searchContainer.getEnd());

想想看:您刚刚创建了实例，您希望开始和结束的是什么？

当您创建容器时，您告诉它它应该使用的参数，但是没有在JSP上设置它们，例如：

<liferay-ui:search-container emptyResultsMessage="there-are-no-file-entries" iteratorURL="${filesRenderUrl}" delta="${files_searchDelta}" total="${files_searchTotal}" curParam="files" deltaParam="files">

总之，如果您想在java方法中控制搜索容器，则需要相应地设置结果：

private static int getStart( int current, int delta ) {

    return ( current - 1 ) * delta;
}

private static int getEnd( int first, int delta ) {

    return first + delta;
}
