- 在pom.xml中添加上传附件依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.3</version>
</dependency>
- 编写上传附件页面upload.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form name="uploadForm" method="post" action="/upload" enctype="multipart/form-data" >
<div style="margin: 10px 10px 10px 10px;">
<input type="file" name="file" multiple value="请选择附件..." title="上传附件" /><br>
<div style="margin-top: 5px;"></div>
<input type="submit"value="提交">
</div>
</form>
</body>
</html>
- 编写controller
package com.example.springbootdemo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import org.thymeleaf.util.StringUtils;
import javax.servlet.http.HttpServletRequest;
import java.io.*;
import java.util.Date;
@Controller
public class TestController {
@RequestMapping("/uploadfile")
public String uploadFile(){
return "upload";
}
@RequestMapping(value="/upload",method = RequestMethod.POST)//MultipartFile,CommonsMultipartFile
public String upload( MultipartFile file) throws IOException {
//用来检测程序运行时间
long startTime=System.currentTimeMillis();
System.out.println("fileName:"+file.getOriginalFilename());
try {
// File fileDirectory = new File("E:/上传文件/"+new Date().getTime());
// if(fileDirectory.exists()){
//
// }else {
// fileDirectory.mkdirs();
// }
//获取输出流
OutputStream os=new FileOutputStream("E:\\Idea_workspace\\helloworld\\springbootdemo\\uploadfiles\\"+new Date().getTime()+file.getOriginalFilename());
//获取输入流 CommonsMultipartFile 中可以直接得到文件的流
InputStream is=file.getInputStream();
int temp;
//一个一个字节的读取并写入
while((temp=is.read())!=(-1))
{
os.write(temp);
}
os.flush();
os.close();
is.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
long endTime=System.currentTimeMillis();
System.out.println("方法一的运行时间:"+String.valueOf(endTime-startTime)+"ms");
return "success";
}
}
- 示例页面,可以上传多个文件(需要在同一文件夹下)
点击提交,跳转到提交成功页面
