1、編寫頁面uploadFile.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>上傳文件</title> </head> <body> <form action="uploadFile" method="post" enctype="multipart/form-data"> <input type="file" name="myfile"> <input type="submit" value="上傳"> </form> </body> </html>
2、編寫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) publicMap<String,Object> uploadFile(MultipartFile myfile){ Map<String,Object> returnMap=new HashMap<String,Object>(); try{ myfile.transferTo(new File("e:/"+myfile.getOriginalFilename())); returnMap.put("msg","上傳成功"); }catch (Exception e){ e.printStackTrace(); returnMap.put("msg","上傳失敗"); } return returnMap; } }
3、編寫啟動類
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、設置上傳文件的大小限制
需要添加一個springboot的配置文件，名字為application.properties,放在resource文件夾下，添加以下內容
#設置單個文件上傳的最大大小 spring.http.multipart.maxFileSize=200MB #設置一次請求上傳文件的總容量的大小 spring.http.multipart.maxRequestSize=200MB
5、啟動項目即可,在瀏覽器中訪問http://localhost:8080/uploadFile.html即可
