1、引入jar包依赖
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
2、fileupload.html
<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org/">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form th:action="@{/upload}" method="post" enctype="multipart/form-data">
<input type="file" name="fileTest"/>
<input type="submit" value="上传"/>
</form>
</body>
</html>
3、FileDealer.java
package com.csp.springbootjwt.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.IOException;
@Controller
public class FileDealer {
@RequestMapping("/upload")
@ResponseBody
public String upload(MultipartFile fileTest, HttpServletRequest request) throws IOException {
//获取文件的原始名
String filename = fileTest.getOriginalFilename();
System.out.println(filename);
//根据相对路径获取绝对路径
String realPath = request.getSession().getServletContext().getRealPath("/");
fileTest.transferTo(new File(realPath,filename));
return "success";
}
@RequestMapping("/file")
public String tofile(){
return "/fileupload";
}
}
