excel批量导入数据

这个功能也是我以前项目中经常用到的，感觉很实用，必须拿来分享下：

excel进行批量导入数据，结合struts2+ajax

导入的视图：batchAdd.ftl(视图无关紧要的，可以换成其他任何视图，就是普通的form表单的提交，就是这里是调用ajax)

<div class="controltitle">当前操作：excel批量导入学生信息</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">[点击下载excel样例]</a>
</form>
</div>
<div>
    <div>下面是导入的excel的样式<font color = "red">[上传的excel中的内容必须按照这个顺序就行排版，否则存储内容的位置会错乱的]</font></div>
    <table class="tablefirst" id="radioSubStyle">
        <tr>
            <th>姓名</th><th>学号</th><th>性别</th><th>籍贯</th><th>专业</th><th>学制</th><th>入学年份</th>
            <th>毕业年份</th><th>工作省市</th><th>工作单位</th><th>工作岗位</th><th>职务职称</th>
            <th>电话</th><th>手机</th><th>qq</th><th>邮箱</th><th>通信地址</th><th>家庭地址</th>
        </tr>
        <tr>
            <td>沈浪</td><td>1006010054</td><td>男</td><td>汉</td><td>眼7</td><td>7</td><td>2009-11-11</td>
            <td>2011-11-11</td><td>浙江</td><td>医院</td><td>临床</td><td>主任</td>
            <td>642</td><td>159</td><td>5449</td><td>544@qq.com</td><td>杭州</td><td>杭州</td>
        </tr>
        <tr>
            <td>沈浪</td><td>1006010024</td><td>男</td><td>汉</td><td>眼7</td><td>7</td><td>2009-11-11</td>
            <td>2011-11-11</td><td>浙江</td><td>医院</td><td>临床</td><td>主任</td>
            <td>642</td><td>159</td><td>5449</td><td>544@qq.com</td><td>杭州</td><td>杭州</td>
        </tr>
        <tr>
            <td>沈浪</td><td>1006010034</td><td>男</td><td>汉</td><td>眼7</td><td>7</td><td>2009-11-11</td>
            <td>2011-11-11</td><td>浙江</td><td>医院</td><td>临床</td><td>主任</td>
            <td>642</td><td>159</td><td>5449</td><td>544@qq.com</td><td>杭州</td><td>杭州</td>
        </tr>
    </table>
    <div><font color="red">注：①excel各列的顺序必须按样式的顺序，而内容可依实际内容而定；这里不支持照片的导入，照片可在修改中进行上传②性别只能为‘男’与‘女’；③专业只能填：眼视光七年制；眼视光本科；眼视光专科；否则会影响后面的查询</font></div>
</div>
<div id="excelUploadMsg"></div>

传入的js(ajax+文件的验证)：这里涉及到的ajax可以去阅读：http://www.cnblogs.com/shenliang123/archive/2012/04/16/2452670.html

/**
 * 以下是上传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);
  
}
//导入考试时进行文件格式校验
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("文件格式不正确！");
        return false;
    } else {
        alert("请选择你需要的导入 的文件");
        return false;
    }
}

struts.xml:

<!-- excel导入 -->
          <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中的方法处理：再次进行文件的验证和调用服务层进行excel的处理和数据持久化

//以下为单文件上传，即excel
    private File uploadExcel;                                                //文件
    private String uploadExcelFileName;                                        //文件名
    private static String[] allowFileType = { "xls", "XLS", "xlsx", "XLSX" };     //控制文件类型
    /**
     * excel批量导入
     * */
    public String excelUpload(){
        try{
            if ((uploadExcelFileName == null) || (uploadExcelFileName.equals(""))) {
                response = "{success:false,msg:'文件名不能为空！'}";
            }
            if (!(FileUtil.validateFileType(uploadExcelFileName, allowFileType))) {   //validateFileType方法在FileUtil中,返回的是boolean值
                response = "{success:false,msg:'文件类型不正确!'}";
            }
            excelBatchInput.uploadStu(uploadExcel);                                    //只传入一个excel文件
            response = "{success:true,msg:'"+excelBatchInput.getFinalMsg()+"'}";    //得到结果的回复
        }catch (Exception e) {
            e.printStackTrace();
            response = "{success:true,msg:'sorry: 导入失败'}";
        }
        return SUCCESS;
    }

serviceInterface:

package xidian.sl.service.admin;

import java.io.File;

public interface ExcelBatchInput {
    /**
     * excel导入的主要逻辑
     * */
    public String uploadStu(File upload);
    /**
     * 导入后的消息
     * */
    public String getFinalMsg();
}

ServiceImpl:(这里对excel的内容没有做过多的验证，只是验证了学号为不重复，大家可以自行对其进行添加)
