Extjs4.0+HSSFWorkbook+SpringMVC实现将数据库中的记录导出到本地Excel格式

Extjs4.0+HSSFWorkbook+SpringMVC实现将数据库中的记录导出到本地Excel格式

自己封装的JS类Share.js

var Share = {};

Share.ExportByExcel = function(url) {

var appWindow = Share.getWin();

appWindow.open(url);

appWindow.focus();

};

调用的前端js

buttons : [{

text : ‘查询‘,

handler : querySettle

}/**, {

text : ‘转账‘,

handler : settleTransfer

}*/, {

text : ‘对账查询‘,

handler : settleQuery

}/**, {

text : ‘失败批量重转账‘,

handler : settleBatch

}*/, {

text : ‘重置查询条件‘,

handler : resetSettle

}, {

text : ‘导出Excel‘,

handler : function() {

var count = settleGrid.getStore().getCount();

var form = settleTopPanel.getForm();

var json = Ext.JSON.encode(form.getValues());

if (count > 0) {

var ids = getSelectedSettle();

if (ids == null) {

ids = "";

}

Share.ExportByExcel(ctx

+ "/exportSettleByExcel.htm?ids=" + ids

+ "&json=" + json);

} else {

Ext.MessageBox.alert("提示", ‘数据为空！‘);

}

}

}]

SpringMVC 的Controller类中

@RequestMapping("/exportSettleByExcel.htm")

public void exportSettleByExcel(@RequestParam String ids, @RequestParam String json, ModelMap map,HttpServletRequest request,

HttpServletResponse response) throws Exception {

logger.info("-------1------- exportSettleByExcel start!");

SettlementModel settlementModel = (SettlementModel) JSONCommonUtils.jsonToObject(json, SettlementModel.class);

List<SettleWaste> lisw = null;

if (settlementModel != null) {

String filename = "";

filename = "结算记录-" + settlementModel.getStartTime() + "到"

+ settlementModel.getEndTime();

settlementModel.setIds(ids);

lisw = settlementWasteService.querySettleWaste(settlementModel, ids);

if (lisw != null && lisw.size() > 0) {

HSSFWorkbook wb = SettleExcel.getHSSFWorkbook(lisw, filename);

PoiUtil.saveExcel(filename, request, response, wb);

}

}

}
