SpringMVC文件上传
1、 导入依赖
<!-- https://mvnrepository.com/artifact/commons-io/commons-io --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <!-- https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency>
代码实现
2、 配置spring-mvc.xml
<!--文件上传解析器-->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!--文件上传的字符集-->
<property name="defaultEncoding" value="UTF-8"></property>
<!--文件的总大小-->
<property name="maxUploadSize" value="50000000"></property>
<!--单个文件的大小-->
<property name="maxUploadSizePerFile" value="500000"></property>
</bean>代码实现
3、 index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>文件上传案例</title>
</head>
<body>
<form action="/file/uploadOne" method="post" enctype="multipart/form-data">
<input type="file" name="upload"/><br/>
<input type="submit" value="提交"/>
</form>
</body>
</html>代码实现
4、FileuploadController
@Controller
@RequestMapping("/file")
public class FileuploadController {
/**
* 单文件上传
* @param upload
* @param session
* @return
* @throws IOException
*/
@RequestMapping("/uploadOne")
public String fileuploadOne(MultipartFile upload, HttpSession session) throws IOException {
//获取绝对路径
String realPath = session.getServletContext().getRealPath("/upload");
//获取文件上传提交的文件名
String filename = upload.getOriginalFilename();
System.out.println(filename);
//组合路径+上传操作
upload.transferTo(new File(realPath,filename));
return "success";
}
}代码实现
