springMVC的简单文件上传

1.导入文件上传所需jar包 - commons-fileupload-1.2.2.jar - commons-io-2.4.jar

2.配置多部件解析器 — springMVC.xml

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 上传文件最大限制(单位kb) --> <property name="maxUploadSize" value="104857600"/> </bean>

3.表单修改

<form action="${pageContext.request.contextPath}/file/upload" method="post" enctype="multipart/form-data"> <input type="file" name="myFile"/> </form>

4.Controller编写

@Controller @RequestMapping("/file") public class FileController{ @RequestMapping("/upload") public void upload(MultipartFile myFile){ if(myFile != null && myFile.getSize()>0){ // 获取文件名 String fileName = myFile.getOriginalFileName(); File file = new File("F:\\upload\\"+fileName); myFile.transferTo(file); System.out.println("生成的文件名:"+file.getName()); } } }
