1、编写页面uploadFile.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>上传文件</title>
</head>
<body>
<form action="uploadFile" method="post" enctype="multipart/form-data">
<input type="file" name="myfile">
<input type="submit" value="上传">
</form>
</body>
</html>
2、编写controller
package com.bjsxt.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.util.HashMap;
import java.util.Map;
/**
* Created by Administrator on 2019/2/5.
*/
@RestController
public class UploadFileController {
@RequestMapping(value = "/uploadFile",method = RequestMethod.POST)
public Map<String,Object> uploadFile(MultipartFile myfile){
Map<String,Object> returnMap=new HashMap<String,Object>();
try{
myfile.transferTo(new File("e:/"+myfile.getOriginalFilename()));
returnMap.put("msg","上传成功");
}catch (Exception e){
e.printStackTrace();
returnMap.put("msg","上传失败");
}
return returnMap;
}
}
3、编写启动类
package com.bjsxt;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Created by Administrator on 2019/2/5.
*/
@SpringBootApplication
public class App {
public static void main(String[] args){
SpringApplication.run(App.class,args);
}
}
4、设置上传文件的大小限制
需要添加一个springboot的配置文件，名字为application.properties,放在resource文件夹下，添加以下内容
#设置单个文件上传的最大大小 spring.http.multipart.maxFileSize=200MB #设置一次请求上传文件的总容量的大小 spring.http.multipart.maxRequestSize=200MB
5、启动项目即可,在浏览器中访问http://localhost:8080/uploadFile.html即可
目录结构
