导入导出功能

一，步骤

1.导入：

一.ftl

<form id="form" action="" enctype="multipart/form-data" method="post"  >
    <input type="file" id="fileID" name="fileName" class="btn dropdown-toggle btn-primary" style="width: 220px; float:left;" />                    
     <input type="hidden" name="projectId" id="projectId" value="">
    <input type="button" value="导入源声" onclick="importList();" class="btn dropdown-toggle btn-success" style="margin-left:20px;"/>
</form>

注意：后台获取属性的值，必须指定 name = ""

二.js

function importList() {
    var filePath = $("#fileID").val();
     if (filePath == '') {
         alert('请选择文件!');
         return;
     }    
     if(pnationId == '-1' || nationId == '-1'){
         alert('请选择国家!');
         return;
     }
     var form = $("#form");
     var projectId = GetQueryString("projectId ");
     $('#projectId').val(projectId);
     form.attr("action", "/nps/analysis/import");
     form.attr("method", "POST");
     form.submit();
}

//获取projectId
function GetQueryString(name) {
    var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
    var r = window.location.search.substr(1).match(reg);
    if (r != null)
        return  unescape(r[2]);
    return null;
}

三.controller

@RequestMapping(value="/analysis/import",method = RequestMethod.POST)
public String importSource(HttpServletRequest request,@RequestParam("fileName") CommonsMultipartFile file, Integer projectId){
    InputStream in =null;  
    String msg = "";        
    try {
        in = file.getInputStream();
        msg = npsSourceAnalysisService.importList(in, file.getOriginalFilename(),pnationId,nationId);    
        in.close();
    } catch (IOException e) {
        e.printStackTrace();
        logger.info(e.getMessage());
        msg = "导入失败！";
    } finally {  
            if (in != null) {  
                try {
                     in.close(); // 关闭流  
                } catch (IOException e) {  
                    logger.debug("in close IOException:" + e.getMessage());  
                }  
            }
    }
    return "redirect:/nps/analysis/list?projectId="+projectId+"&msg="+msg;
}

四.service

public String importList(InputStream in,String fileName);


    @Transactional
    public String importList(InputStream in, String fileName,Integer pnationId,Integer nationId) {                
        String[][] table = null;
        String msg = null;
        try {
            table = ExcelUtils.readExcel(in,fileName,0);
        } catch (Exception e) {
            e.printStackTrace();
            return "文件导入失败，请检查文件格式！";
        }
        Map<String,Integer> tableColumMap = new HashMap<String, Integer>();
        if (CheckUtils.isNullOrBlank(table)
                || table.length == 0) {
            return "表格中没有任何数据！";
        }
        if (table.length == 1) {
            return "表格中只存在表头数据！";
        }
        //校验导入文件内容
        for (int i = 0; i < table[0].length; i++) {
            String cell = table[0][i].trim();
            tableColumMap.put(cell, i);
        }
        
        List<String> errorMsgs = new ArrayList<String>();
        String[] titles ={"ID","描述","产品名称","型号","版本","时间","次数","得分（问题1）","得分（问题2）"};
        for (int i = 0; i < titles.length; i++) {
            String title = titles[i];
            if(!tableColumMap.containsKey(title)){
                errorMsgs.add("Excel表格表头列有误,不存在"+title+"列，请修改Excel后导入");
                if(errorMsgs.size() >= 10) return "导入文件表头不正确，请检查后重新导入！";
            }
        }
                        
        if (errorMsgs.size() == 0) {            
            NPSSourceAnalysis npsSourceAnalysis=new NPSSourceAnalysis();
            
            
            for (int i = 1; i < table.length; i++) {
                String sourceID = table[i][tableColumMap.get("ID")].trim();
                String descript = table[i][tableColumMap.get("描述")].trim();
                String product = table[i][tableColumMap.get("名称")].trim();
                String inner = table[i][tableColumMap.get("型号")].trim();                
                String ROM = table[i][tableColumMap.get("版本")].trim();
                String createTime = table[i][tableColumMap.get("时间")].trim();
                String SN = table[i][tableColumMap.get("SN")].trim();
                String CSR = table[i][tableColumMap.get("得分（问题1）")].trim();
                String recommend = table[i][tableColumMap.get("得分（问题2）")].trim();                                
                
                    npsSourceAnalysis.setSourceID(Integer.parseInt(sourceID));
                    npsSourceAnalysis.setDescript(descript);
                    npsSourceAnalysis.setProduct(product);
                    npsSourceAnalysis.setInnerVersion(inner);
                    npsSourceAnalysis.setOuterVersion(outer);
                    npsSourceAnalysis.setROM(ROM);
                    npsSourceAnalysis.setCreateTime(createTime);
                    npsSourceAnalysis.setSN(SN);                                
                    npsSourceAnalysis.setCSR(Integer.parseInt(CSR));
                    npsSourceAnalysis.setRecommend(Integer.parseInt(recommend));
                    npsSourceAnalysis.setHandled(0);
                    npsSourceAnalysis.setAbroad(0);                    
                    npsSourceAnalysis.setPnationId(pnationId);
                    npsSourceAnalysis.setNationId(nationId);                    
                    nPSSourceAnalysisMapper.insert(npsSourceAnalysis);                                                
            }
            
        } else{
            for (String errorMsg : errorMsgs) {
                msg = msg + errorMsg +";";
            }
        }    
            return msg;
     }

五,需要的工具类

            }                
        }
    };
    int[] redTitleCols = {};//设置红色样式的列表头
    int[] colsWidths = {3000,3000,5000,15000,2500,2500,3500,5000,5000,2000,3000,3000,3000,3000,3000};//设置列宽
