excel批量導入數據

這個功能也是我以前項目中經常用到的，感覺很實用，必須拿來分享下：

excel進行批量導入數據，結合struts2+ajax

導入的視圖：batchAdd.ftl(視圖無關緊要的，可以換成其他任何視圖，就是普通的form表單的提交，就是這里是調用ajax)

<div class="controltitle">當前操作：excel批量導入學生信息</div>
<div> 
<form action="excelUploadAction.action" method="post" enctype="multipart/form-data" id="uploadInfor"
        onSubmit="return validateuploadInforFile(this);">
            <input type="file" name="uploadExcel">
            <input type="submit" value="提交"/><a href = "download/stuExcel.xls">[點擊下載excel樣例]</a>
</form>
</div>
<div>
    <div>下面是導入的excel的樣式<font color = "red">[上傳的excel中的內容必須按照這個順序就行排版，否則存儲內容的位置會錯亂的]</font></div>
    <table class="tablefirst" id="radioSubStyle">
        <tr>

            <th>畢業年份</th><th>工作省市</th><th>工作單位</th><th>工作崗位</th><th>職務職稱</th>
            <th>電話</th><th>手機</th><th>qq</th><th>郵箱</th><th>通信地址</th><th>家庭地址</th>

    </table>
    <div><font color="red">注：①excel各列的順序必須按樣式的順序，而內容可依實際內容而定；這里不支持照片的導入，照片可在修改中進行上傳②性別只能為‘男’與‘女’；③專業只能填：眼視光七年制；眼視光本科；眼視光專科；否則會影響后面的查詢</font></div>

傳入的js(ajax+文件的驗證)：這里涉及到的ajax可以去閱讀：http://www.cnblogs.com/shenliang123/archive/2012/04/16/2452670.html

/**
 * 以下是上傳excel的一系列方法
 * */
function validateuploadInforFile(form){
        if(!validateExcelUpLoadFile(form)) return false;
        var options = { 
            dataType: 'json',
            success: showResponse 
        };
        $("#uploadInfor").ajaxSubmit(options); 
        return false;
}

function showResponse(responseText){
  $("#excelUploadMsg").empty();
  $("#excelUploadMsg").append(responseText.msg);
  
}
//導入考試時進行文件格式校驗
function validateExcelUpLoadFile(form) {
    var fileName = form.uploadExcel.value;
    
    if (fileName != "" ) {
        var fileType = (fileName.substring(fileName.lastIndexOf(".") + 1, fileName.length)).toLowerCase();
        var suppotFile = ["xls", "XLS", "xlsx", "XLSX"];
        for (var i = 0; i < suppotFile.length; i++) {
            if (suppotFile[i] == fileType) {
                return true;
            } else {
                continue;
            }
        }
        alert("文件格式不正確！");
        return false;
    } else {
        alert("請選擇你需要的導入 的文件");
        return false;
    }
}

struts.xml:

<!-- excel導入 -->
          <action name="excelUploadAction" class="xidian.sl.action.StuInforAction" method = "excelUpload">
              <interceptor-ref name="fileUpload"/>
              <interceptor-ref name="defaultStack" />
              <result name="success">/WEB-INF/responseMsg.jsp</result>
          </action>

action中的方法處理：再次進行文件的驗證和調用服務層進行excel的處理和數據持久化

//以下為單文件上傳，即excel
    private File uploadExcel;                                                //文件
    private String uploadExcelFileName;                                        //文件名
    private static String[] allowFileType = { "xls", "XLS", "xlsx", "XLSX" };     //控制文件類型
    /**
     * excel批量導入
     * */
    public String excelUpload(){
        try{
            if ((uploadExcelFileName == null) || (uploadExcelFileName.equals(""))) {
                response = "{success:false,msg:'文件名不能為空！'}";
            }
            if (!(FileUtil.validateFileType(uploadExcelFileName, allowFileType))) {   //validateFileType方法在FileUtil中,返回的是boolean值
                response = "{success:false,msg:'文件類型不正確!'}";
            }
            excelBatchInput.uploadStu(uploadExcel);                                    //只傳入一個excel文件
            response = "{success:true,msg:'"+excelBatchInput.getFinalMsg()+"'}";    //得到結果的回復
        }catch (Exception e) {
            e.printStackTrace();
            response = "{success:true,msg:'sorry: 導入失敗'}";
        }
        return SUCCESS;
    }

serviceInterface:

package xidian.sl.service.admin;

import java.io.File;

public interface ExcelBatchInput {
    /**
     * excel導入的主要邏輯
     * */
    public String uploadStu(File upload);
    /**
     * 導入后的消息
     * */
    public String getFinalMsg();
}

ServiceImpl:(這里對excel的內容沒有做過多的驗證，只是驗證了學號為不重復，大家可以自行對其進行添加)
