用SpringMvc实现Excel导出功能

以前只知道用poi导出Excel，最近用了SpringMvc的Excel导出功能，结合jxl和poi实现，的确比只用Poi好，两种实现方式如下：

一、结合jxl实现：

1、引入jxl的所需jar包：

<dependency org="net.sourceforge.jexcelapi" name="jxl" rev="2.6.3" conf="compile->compile(*),master(*);runtime->runtime(*)" transitive="false"/>

2、接口和实现类:

  接口源码：

public interface ExportRS {
/**
     * 息导出到Excel
     * <P>
     * <ul>
     * </ul>
     * </P>
     * 
     * @return 导出文件流
     */
    @RequestMapping(value="/export/excel" , method={RequestMethod.POST,RequestMethod.GET})
    ModelAndView exportExcel(@RequestParam(value = "condition", required = true)  String condition,
            HttpServletRequest request, HttpServletResponse response);
}

实现源码：

@RestController
public class ExportRSImpl implements ExportRS {
@Override
    public ModelAndView exportExcel(String condition, 
            HttpServletRequest request, HttpServletResponse response) {
        try{
            NSearch nSearch = JsonObjUtil.JsonToObj(condition, NSearch.class);
            String userId = SecurityHelper.getCurrentUserId();
            QueryResult result = _mupport.search(nSearch, userId);
            long total = result.getTotalCount();
            //System.out.println("资产总数是："+total);
            Map<String, Object> model = new HashMap<String, Object>();  
            model.put("total", total+"");
            model.put("filename", "资产信息-"+new SimpleDateFormat("yyyyMMddhhmmss").format(new Date())+".xls");
            model.put("items", result.getItems());
            //资产类型
            List<AssetCategoryDefine> categoryList =  _assetCatRp.findAllRestrict();
            //所有用户
            String stationId = SecurityHelper.getCurrentStationId();
            List<User> userList = _rpUser.findByStationId(stationId);
            model.put("allUser", userList);
            model.put("allCategory", categoryList);
            
            return new ModelAndView(new JExcelView(),model);
        } catch (Throwable e) {
            throw new AssetRuntimeException(e);
        }
    }
}
