基於jxls技術導入Excel模版數據

前言：公司有項目需要用到導入excel數據進行數據統計分析，進行對比後，發現jxls比poi少寫不少代碼，api調用也相當方便。從而在項目中採用此技術，特輯之。（闡述方式從底層到視圖層）

1、確定excel文檔中個字段的含義和文檔格式。

2、對應編寫excel相近的xml模板文件：

<?xml version="1.0" encoding="utf-8" ?>
<workbook>

//sheet名字

	<worksheet name="XXXX考勤表">
		<section startRow="0" endRow="0"/>
		<loop startRow="1" endRow="1" items="attendanceDatas"
			var="attendanceData" varType="net.xxxxtech.xxoa.vo.AttendanceData">
			<section startRow="1" endRow="1">
				<mapping row="1" col="0">attendanceData.number</mapping>
				<mapping row="1" col="1">attendanceData.attendNum</mapping>
				<mapping row="1" col="2">attendanceData.selfDefineNum</mapping>
				<mapping row="1" col="3">attendanceData.name</mapping>
				<mapping row="1" col="4">attendanceData.isCapacityArrange</mapping>
				<mapping row="1" col="5">attendanceData.attendDate</mapping>
				<mapping row="1" col="6">attendanceData.correspondingStep</mapping>
				<mapping row="1" col="7">attendanceData.openTime</mapping>
				<mapping row="1" col="8">attendanceData.closingTime</mapping>
				<mapping row="1" col="9">attendanceData.signInTime</mapping>
				<mapping row="1" col="10">attendanceData.signOutTime</mapping>
				<mapping row="1" col="11">attendanceData.dueNum</mapping>
				<mapping row="1" col="12">attendanceData.trueNum</mapping>
				<mapping row="1" col="13">attendanceData.lateTime</mapping>
				<mapping row="1" col="14">attendanceData.earlyTime</mapping>
				<mapping row="1" col="15">attendanceData.isAbsent</mapping>
				<mapping row="1" col="16">attendanceData.overtimeTime</mapping>
				<mapping row="1" col="17">attendanceData.workTime</mapping>
				<mapping row="1" col="18">attendanceData.exceptionalCase</mapping>
				<mapping row="1" col="19">attendanceData.isAttend</mapping>
				<mapping row="1" col="20">attendanceData.isSignOut</mapping>
				<mapping row="1" col="21">attendanceData.dept</mapping>
				<mapping row="1" col="22">attendanceData.usual</mapping>
				<mapping row="1" col="23">attendanceData.weekend</mapping>
				<mapping row="1" col="24">attendanceData.holiday</mapping>
				<mapping row="1" col="25">attendanceData.attendTime</mapping>
				<mapping row="1" col="26">attendanceData.usualOvertime</mapping>
				<mapping row="1" col="27">attendanceData.weekendOvertime</mapping>
				<mapping row="1" col="28">attendanceData.holidayOvertime</mapping>
			</section>
			<loopbreakcondition>
				<rowcheck offset="0">
				<cellcheck offset="0"></cellcheck>
				</rowcheck>
			</loopbreakcondition>
		</loop>
	</worksheet>
</workbook>

3、編寫對應的vo類：

public class AttendanceData {
    private String number;//序號

    private String attendNum;//考勤號碼

    private String selfDefineNum;//自定義編號

    private String name;//姓名

    private String isCapacityArrange;//是否智能排班(true?false字段)

    private String attendDate;

    private String correspondingStep;//對應時段

    private String openTime;//上班時間

    private String closingTime;//下班時間

    private String signInTime;//簽到時間

    private String  signOutTime;//簽退時間

    private String  dueNum;//應到

    private String  trueNum;//實到

    private String  lateTime;//遲到時間

    private String  earlyTime;//早退時間

    private String  isAbsent;//是否曠工

    private String  overtimeTime;//加班時間

    private String  workTime;//工作時間

    private String  exceptionalCase;//例外情況

    private String  isAttend;//應簽到

    private String  isSignOut;//應簽退

    private String  dept;//部門

    private String  usual;//平日

    private String  weekend;//週末

    private String  attendTime;//出勤時間/工作時間

    private String  usualOvertime;//平日加班

    private String  weekendOvertime;//週末加班

    private String  holidayOvertime;//節假日加班

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public String getAttendNum() {
        return attendNum;
    }

    public void setAttendNum(String attendNum) {
        this.attendNum = attendNum;
    }

    public String getSelfDefineNum() {

        return isCapacityArrange;
    }

    public void setIsCapacityArrange(String isCapacityArrange) {
        this.isCapacityArrange = isCapacityArrange;
    }

    public String getAttendDate() {
        return attendDate;
    }

    public void setAttendDate(String attendDate) {
        this.attendDate = attendDate;
    }

    public String getCorrespondingStep() {
        return correspondingStep;
    }

    public void setCorrespondingStep(String correspondingStep) {

    }

    public String getOpenTime() {
        return openTime;
    }

    public void setOpenTime(String openTime) {

    }

    public String getClosingTime() {

    }

    public void setClosingTime(String closingTime) {
        this.closingTime = closingTime;
    }

    public String getSignInTime() {
        return signInTime;
    }

    public void setSignInTime(String signInTime) {
        this.signInTime = signInTime;
    }

    public String getSignOutTime() {
        return signOutTime;
    }

    public void setSignOutTime(String signOutTime) {
        this.signOutTime = signOutTime;
    }

    public String getDueNum() {
        return dueNum;
    }

    public void setDueNum(String dueNum) {
        this.dueNum = dueNum;
    }

    public String getTrueNum() {
        return trueNum;
    }

    public void setTrueNum(String trueNum) {
        this.trueNum = trueNum;
    }

    public String getLateTime() {
        return lateTime;
    }

    public void setLateTime(String lateTime) {
        this.lateTime = lateTime;
    }

    public String getEarlyTime() {
        return earlyTime;
    }

    public void setEarlyTime(String earlyTime) {
        this.earlyTime = earlyTime;
    }

    public String getIsAbsent() {
        return isAbsent;
    }

    public void setIsAbsent(String isAbsent) {
        this.isAbsent = isAbsent;
    }

    public String getOvertimeTime() {
        return overtimeTime;
    }

    public void setOvertimeTime(String overtimeTime) {
        this.overtimeTime = overtimeTime;
    }

    public String getWorkTime() {
        return workTime;
    }

    public void setWorkTime(String workTime) {
        this.workTime = workTime;
    }

    public String getExceptionalCase() {
        return exceptionalCase;
    }

    public void setExceptionalCase(String exceptionalCase) {
        this.exceptionalCase = exceptionalCase;
    }

    public String getIsAttend() {
        return isAttend;
    }

    public void setIsAttend(String isAttend) {
        this.isAttend = isAttend;
    }

    public String getIsSignOut() {
        return isSignOut;
    }

    public void setIsSignOut(String isSignOut) {
        this.isSignOut = isSignOut;
    }

    public String getDept() {
        return dept;
    }

    public void setDept(String dept) {
        this.dept = dept;
    }

    public String getUsual() {
        return usual;
    }

    public void setUsual(String usual) {
        this.usual = usual;
    }

    public String getWeekend() {
        return weekend;
    }

    public void setWeekend(String weekend) {
        this.weekend = weekend;
    }

    public String getHoliday() {
        return holiday;
    }

    public void setHoliday(String holiday) {
        this.holiday = holiday;
    }

    public String getAttendTime() {
        return attendTime;
    }

    public void setAttendTime(String attendTime) {
        this.attendTime = attendTime;
    }

    public String getUsualOvertime() {

    public void setWeekendOvertime(String weekendOvertime) {
        this.weekendOvertime = weekendOvertime;
    }

    public String getHolidayOvertime() {
        return holidayOvertime;
    }

    public void setHolidayOvertime(String holidayOvertime) {
        this.holidayOvertime = holidayOvertime;
    }
}

4、service類中進行數據處理（讀excel內容），其中xml模板文件寫配置：

private final static String xmlConfig = "attendanceData.xml";

@Override
    public List<AttendanceData> importAttendData(String filePath) {

        XLSReader mainReader;

        try {
            InputStream inputXML = new BufferedInputStream(getClass().getClassLoader().getResourceAsStream(xmlConfig));
            mainReader = ReaderBuilder.buildFromXML(inputXML);
            InputStream inputXLS = new BufferedInputStream(new FileInputStream(filePath));
            List<AttendanceData> attendanceDatas = new ArrayList<>();

            Map<String, Object> beans = new HashMap();
            beans.put("attendanceDatas", attendanceDatas);
            XLSReadStatus readStatus = mainReader.read(inputXLS, beans);
            return attendanceDatas;


        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SAXException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (InvalidFormatException e) {
            e.printStackTrace();
        }
        return null;
    }

5、controller類進行接口調用：

@RequestMapping(value = "importAttendData", method = RequestMethod.POST)
    @ResponseBody
    public ResponseResult importTestResult(MultipartFile myfile, HttpServletRequest req) throws Exception {
        ResponseResult responseResult = new ResponseResult();
        String templateFile = req.getSession().getServletContext().getRealPath("/import");
        try {
            if (myfile.isEmpty()) {
                responseResult.setResult(Result.WARNING);
                responseResult.setMessage("導入文件爲空!!");
                return responseResult;//URLEncoder.encode("[<導入文件爲空!!>]", "UTF-8");
            } else {
                String fileName = myfile.getOriginalFilename();
                if (!fileName.endsWith(".xls") && !fileName.endsWith(".xlsx") && !fileName.endsWith(".xlsm")) {
                    responseResult.setResult(Result.WARNING);
                    responseResult.setMessage("文件類型錯誤，導入文件僅允許excel文件類型!!");
                    return responseResult;
                }
                File file = new File(templateFile);
                if (!file.exists()) {
                    file.mkdirs();
                }

                FileUtils.copyInputStreamToFile(myfile.getInputStream(), new File(templateFile, myfile.getOriginalFilename()));


                String resultFilePath = templateFile + File.separator + fileName;

                List<AttendanceData> testReportResults = attendanceService.importAttendData(resultFilePath);
                String errorInfo = "";
                if (testReportResults != null) {
                    //i從1開始，忽略模板中的標題欄
                    StringBuilder stringBuilder = attendanceService.updateAttendDataByCode(testReportResults);
                    if (stringBuilder.length() > 0) {
                        String inf = stringBuilder.toString();
                        responseResult.setResult(Result.WARNING);
                        responseResult.setMessage(inf);
                        return responseResult;

//                        return java.net.URLEncoder.encode("[<" + inf + ">]", "UTF-8");

                    } else {

                        responseResult.setResult(Result.SUCCESS);
                        responseResult.setMessage("導入成功!!");
                        return responseResult;
//                        return "SUCCESS";//URLEncoder.encode("[<導入成功!!>]", "UTF-8");

                    }

                } else {
                    responseResult.setResult(Result.FAILURE);
                    responseResult.setMessage("導入文件內容格式錯誤!!");
                    return responseResult;
//                    return java.net.URLEncoder.encode("[<導入文件內容格式錯誤!!>]", "UTF-8"); //URLEncoder.encode("[<導入文件內容格式錯誤!!>]", "UTF-8");
                }

            }
        } catch (Exception e) {
            e.printStackTrace();
            responseResult.setResult(Result.FAILURE);
            responseResult.setMessage("系統正忙，請稍後再試!!");
            return responseResult;
//                return java.net.URLEncoder.encode("[<系統正忙，請稍後再試!!>]", "UTF-8");
        }

    }

6、視圖層jsp通過ajax進行數據導入：

6.1、彈出模態框進行數據導入

<kendo:window name="reportResultWindow" title="導入考勤文檔" draggable="true" resizable="true" width="500"
              height="400" visible="false">
    <kendo:window-content>
        <div>
            <form id="submitReportResult" method="post" enctype="multipart/form-data"
                  style="font: 14px bold ;">
                <input type="hidden" id="reportId" name="reportId"/>
                <fieldset>
                    <legend>點擊瀏覽選擇上傳文件</legend>
                    <input type="file" name="myfile" style="color:red;"/>
                </fieldset>
                <hr/>
                <fieldset>
                    日誌：<textarea rows="10" cols="60" id="log"
                                 style="position: relative;right:0px;margin-top: 10px;"></textarea>
                </fieldset>
                註釋：
                <div class="heading-buttons">
                    <div class="buttons pull-right" style="margin-right: 0px; margin-top: 20px;">
                        <input type="button" class="btn btn-primary right" value="確定"
                               onclick="importReportResult();"/>
                    </div>
                </div>
            </form>
        </div>
    </kendo:window-content>
</kendo:window>

6.2 excel文檔導入提交

function importReportResult() {
            var reportId = $("#reportId").val();
            if (confirm("確定導入考勤數據?")) {
                $("#log").val("正在導入中...");
                $("#submitReportResult").ajaxSubmit({
                    type: 'post',
                    url: "../assets/importAttendData.do",
                    success: function (data) {
                        var dataContent = JSON.stringify(decodeURI(data));
                        dataContent = dataContent.substring(dataContent.lastIndexOf("[<") + 2, dataContent.lastIndexOf(">]"));
                        var content1 = dataContent.substring(0, dataContent.lastIndexOf("!!") + 2);
                        var content2 = dataContent.substring(dataContent.lastIndexOf("!!") + 2, dataContent.length - 2);
                        if (content1 == "導入成功!!") {
                            $("#log").val(content1 + "\n" + content2);
                            $("#grid").data("kendoGrid").dataSource.read();
                            // $('#submit').disabled=false;
                        } else {
                            $("#log").val(dataContent);
                        }
                    },
                    error: function (XmlHttpRequest, textStatus, errorThrown) {
                        $("#log").val("導入異常！");
                    }
                });
            }
        }

或者

 function importReportResult() {
            var userAgent = navigator.userAgent; //取得瀏覽器的userAgent字符串
           /* if (userAgent.indexOf("Opera") > -1) {
                return "Opera"
            }; //判斷是否Opera瀏覽器
            if (userAgent.indexOf("Firefox") > -1) {
                return "FF";
            } //判斷是否Firefox瀏覽器*/

            var reportId = $("#reportId").val();
            if (confirm("確定導入考勤數據?")) {
                $("#log").val("正在導入中...");
                $("#submitReportResult").ajaxSubmit({
                    type: 'post',
                    url: "../assets/importAttendData.do",
                    data:$(this).serialize(),
                    dataType:"text",
                    success: function (data) {
                        if (userAgent.indexOf("Chrome") > -1){
                            var reg = /<pre.+?>(.+)<\/pre>/g;
                            var result = data.match(reg);
                            data = RegExp.$1;
                            data = JSON.parse(data);
                            console.info(data.result);
                        }
                        if (data.result == "SUCCESS") {
                            $("#log").val("導入成功");
                            $("#grid").data("kendoGrid").dataSource.read();
                        } else {
                            $("#log").val(data.message);
                        }
                    },
                    error: function (XmlHttpRequest, textStatus, errorThrown) {
                        $("#log").val("導入異常！");
                    }
                });
            }
        }

7、後記，其實jxsl技術還可以進行很好的excel模板導出操作，後續在進行闡述。
