file uploads are mainly divided into the following steps :
(1) New Maven Java project;
(2) to join the corresponding dependence in pom.xml;
(3) Create a new form page (use thymeleaf here);
(4) Prepare controller;
(5) Testing;
(6) To make some restrictions on the uploaded documents;
(7) Multi-File upload implementation
(1) New Maven Java Project
Create a new name called Spring-boot-fileuploadmaven Java project;
(2) to join the corresponding dependence in pom.xml;
Add the appropriate MAVEN dependencies, as explained in the following examples:
<!--
Springboot Parent Node Dependency,
After introducing this, the relevant introduction does not need to add the version configuration,
Springboot will automatically select the most appropriate version to add.
-
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.3.RELEASE</version>
</parent>
<dependencies>
<!--Spring Boot Web support: Mvc,aop ...-
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--thmleaf template dependency. -
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<!--compiled version; -
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
(3) Create a new form page (use thymeleaf here)
Create a new templates in Src/main/resouces (if you've seen a blogger before, you should know that templates is the path to the Spring Boot store template file) and create a new file.html under templates:
<! DOCTYPE html>
xmlns:sec= "Http://www.thymeleaf.org/thymeleaf-extras-springsecurity3" >
<title>hello world!</title>
<body>
<form method= "POST" enctype= "Multipart/form-data" action= "/upload" >
<p> file: <input type= "file" name= "file"/></p>
<p><input type= "Submit" value= "Upload"/></p>
</form>
</body>
(4) Prepare controller;
To write a controller for testing, here are the main implementation of two methods: one is to provide access to the/file path, and the other is to provide post upload/upload method, in particular, see the code implementation:
Package com.kfit;
import Java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
import Java.io.FileOutputStream;
import java.io.IOException;
importOrg.springframework.stereotype.Controller;
importorg.springframework.web.bind.annotation.RequestMapping;
importOrg.springframework.web.bind.annotation.RequestParam;
importorg.springframework.web.bind.annotation.ResponseBody;
importorg.springframework.web.multipart.MultipartFile;
@Controller
Publicclass Fileuploadcontroller {
Access path is: Http://127.0.0.1:8080/file
@RequestMapping ("/file")
Public String file () {
return"/file";
}
/**
* File upload specific implementation method;
*@param file
*@return
*/
@RequestMapping ("/upload")
@ResponseBody
Public Stringhandlefileupload (@RequestParam ("file") multipartfilefile) {
if (!file.isempty ()) {
Try {
/*
* After the execution of this code, the image is uploaded to the path of the project;
* Everyone's own thoughts, if we want to upload the picture to d:/files people can achieve it.
And so on
* Here is a simple example, please refer to yourself, into the actual may require you to do some thinking, such as:
* 1, file path;
* 2, file name;
* 3, file format;
* 4, the file size limit;
*/
Bufferedoutputstreamout =newbufferedoutputstream ( new FileOutputStream ( File.getoriginalfilename ())));
Out.write (File.getbytes ());
Out.flush ();
Out.close ();
}catch(Filenotfoundexceptione) {
E.printstacktrace ();
return "Upload failed," +e.getmessage ();
}catch (Ioexceptione) {
E.printstacktrace ();
return "Upload failed," +e.getmessage ();
