添加自定义导出按钮

<span class="btn btn-primary " style="float:left;margin-right:5px;"  data-bind="click:exportExcelCustom">
            <i class="fa fa-file-excel-o" style="marginright:3px;"></i><@spring.message "导出"/></span>

扩展 viewModel 对象并添加 exportExcelCustom() 方法

<script type="text/javascript">
    var viewModel = Hap.createGridViewModel("#grid" , {
        /*自定义导出*/
        exportExcelCustom: function() {
            var exportConfig = {};
            var columns = [];
            var index = 0;
            var grid = $("#grid").data("kendoGrid"); //获取kendoGrid对象
            console.log(grid)
            for (var i = 0; i < grid.columns.length; i++) { //遍历所有字段
                if (grid.columns[i].field != null && i!=7 && i!=8 && i!=9 && i!=13) {
                    var columnInfo = {};
                    columnInfo["name"] = grid.columns[i].field; //获取字段name
                    columnInfo["title"] = grid.columns[i].title; //获取字段实际显示标题
                    columnInfo["width"] = grid.columns[i].width*0.5; //获取字段显示宽度
                    var align = $('tbody').find('tr')[0].getElementsByTagName('td')
                        [i].style.textAlign; //获取对其⽅方式
                    if (align != null || align != '') {
                        columnInfo["align"] = align;
                    }
                    if (dataSource.options.schema.model.fields[grid.columns[i].field] != null) {//获取字段类型
                        columnInfo["type"] =
                            dataSource.options.schema.model.fields[grid.columns[i].field].type;
                        console.log("获取的数据类型："+dataSource.options.schema.model.fields[grid.columns[i].field].type)
                    }
                    columns[index] = columnInfo; //将数据导⼊入columns中
                    console.log("插入的数据："+columnInfo)
                    index++;
                }
            }
            exportConfig["columnsInfo"] = columns; //将columns数据导⼊入exportConfig中
            exportConfig["param"] = Hap.prepareQueryParameter(this.model.toJSON()); //获取⽹网⻚页限制条件
            exportConfig["fileName"] = "订单"; //设置⽂文件名
            var $inputImg = $('<input>').attr({name: "config", value:
                kendo.stringify(exportConfig)}); //将⻚页⾯面信息传到$inputImg中，定义input，并设置name和value属性
            var
                $inputToken=$('<input>').attr({name:"${_csrf.parameterName}",value:"${_csrf.token}",
                    type:"hidden"}); //传⼊入token，以实现跨域访问，定义input
            var $form = $("<form>"); //定义form
            $form.attr({ //设置form的target，method，action属性
                target: '_self',
                method: 'post',
                action: '${base.contextPath}/i/edi/iftmin/export'
            }).append($inputImg); //在form中添加$inputImg，添加input域
            $form.append($inputToken); //在form中添加$inputToken
            $form.id='smbForm'; //设置form的id
            $("#batchDiv").empty().append($form); //在batchDiv中添加该form
            $($form).submit(); //提交form
            $("#batchDiv").empty(); //置空batchDiv
        },
    }
    );

</script>

在body最后面添加一个DIV

<div id="batchDiv"></div>

在控制器中添加处理逻辑

import com.fasterxml.jackson.databind.JavaType;
import com.fasterxml.jackson.databind.ObjectMapper;

        @Autowired
        private ObjectMapper objectMapper;
        @Autowired private IExportService excelService;
        @RequestMapping(value = "/i/edi/iftmin/export")
        public void exportExcelCustom(HttpServletRequest request, @RequestParam String
                config,
                                      HttpServletResponse httpServletResponse) throws
                IOException {
            IRequest requestContext = createRequestContext(request);
            JavaType type =  objectMapper.getTypeFactory().constructParametrizedType(ExportConfig.class,
                            ExportConfig.class, EdiIftmin.class, ColumnInfo.class);
            ExportConfig<EdiIftmin, ColumnInfo> exportConfig =
                    objectMapper.readValue(config, type);
            excelService.exportAndDownloadExcel("com.hand.tms.orderManage.mapper.EdiIftminMapper.exportExcel", exportConfig, request, httpServletResponse,
                    requestContext);
        }
