这里有新鲜出炉的精品教程,程序狗速度看过来!
Spring是什么呢?首先它是一个开源的项目,而且目前非常活跃;它是一个基于IOC和AOP的构架多层j2ee系统的框架,但它不强迫你必须在每一层 中必须使用Spring,因为它模块化的很好,允许你根据自己的需要选择使用它的某一个模块;它实现了很优雅的MVC,对不同的数据访问技术提供了统一的接口,采用IOC使得可以很容易的实现bean的装配,提供了简洁的AOP并据此实现Transcation Managment,等等
这篇文章主要介绍了SpringMVC上传和解析Excel方法,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
示例:导入相关数据(Excel文件),相关的文件数据编辑好。
XML文件配置
再spring的xml文件中配置要上传文件的大小
- <!-- 上传文件拦截,设置最大上传文件大小 10M=10*1024*1024(B)=10485760 bytes -->
- <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
- <property name="maxUploadSize" value="10485760" />
- </bean>
Jsp界面配置
- <div>
- <form id="sourcefile" name="sourcefile" action="" method="post" enctype="multipart/form-data">
- <input type="button" value="添 加" onClick="addAirLine()" />
- <input style="margin-left: 20px;" id="source_file" name="sourceFile" type="file" value="选择文件" />
- <input style="margin-left: 20px;" data-loading-text="请勿重复提交" type="submit" value="上 传" onClick="upPolicy()">
- <input style="margin-left: 20px;" type="submit" value="下载模板" onClick="return downloadTemplate();">
- </form>
- </div>
js文件
- function upPolicy() {
- document.sourcefile.action = "/login/policy/uploadCSV";
- var submitUrl = document.getElementById("sourcefile").attributes["action"].value;
- $.ajax({
- type: "POST",
- url: submitUrl,
- data: $('#sourcefile').serialize(),
- dataType: "json",
- success: function(result) {
- var json = JSON.parse(result);
- if (json.flag == "0" || json.flag == "1") {
- alert(tableJson.success);
- return;
- }
- }
- })
- }
Controller配置
- @RequestMapping(value = "/uploadCSV", method = RequestMethod.POST)@ResponseBody public String uploadCSV(@RequestParam("sourceFile") MultipartFile sourceFile, HttpServletRequest request, HttpServletResponse response) throws IOException {
- //判断文件是否为空
- if (sourceFile == null) return null;
- //获取文件名
- String name = sourceFile.getOriginalFilename();
- //进一步判断文件是否为空(即判断其大小是否为0或其名称是否为null)
- long size = sourceFile.getSize();
- if (name == null || ("").equals(name) && size == 0) return null;
- //批量导入。参数:文件名,文件。
- boolean b = batchImport(name, sourceFile);
- JSONObject jsonObject = new JSONObject();
- if (b) {
- jsonObject.put("flag", 0);
- jsonObject.put("success", "批量导入EXCEL成功!");
- } else {
- jsonObject.put("flag", 1);
- jsonObject.put("success", "批量导入EXCEL失败!");
- }
- return jsonObject.toString();
- }
分层没有那么的详细,再Controller中做的处理
- public boolean batchImport(String name, MultipartFile file) {
- boolean b = false;
- //创建处理EXCEL
- ExcelUtils readExcel = new ExcelUtils();
- //解析excel,获取客户信息集合。
- List < OTAPolicyModel > cpolicyList = readExcel.getExcelInfo(name, file);
- if (cpolicyList != null) {
- b = true;
- }
- //迭代添加信息(注:实际上这里也可以直接将cpolicyList集合作为参数,
- 在Mybatis的相应映射文件中使用foreach标签进行批量添加。)
- for (OTAPolicyModel customer: cpolicyList) {
- policyDao.insertOTAPolicy(customer);
- }
- return b;
- }
工具类ExcelUtils.java
即上述方法中readExcel.getExcelInfo(name ,file);语句所调用的方法以及其他相关的方法
Apache POI提供API给Java程式对Microsoft Office格式档案读和写的功能。不过这首先得判断Excel的版本而选择不同的Workbook的方式(2003版本对应的是HSSFWorkbook,2007版本及以上对应的是XSSFWorkbook)。此外,一般来说先将在客户端用户上传的文件拷贝一份至服务器的本地磁盘中,然后再从这个拷贝文件中进行读取,这样就避免了因客户端的网络异常或其他状况而在读取时造成的数据流失或损坏的情况。

说明:上面的代码为了阅读便利而先贴的是父方法,后贴的是子方法,而在实际的代码编辑中一般是先编辑子方法,后编辑父方法,如上面应该是先编辑工具类的代码,再编辑服务层的代码,最后编辑控制器的代码。
这样,整个流程就可以了,赶紧拿去测试吧
