Spring Uploading Files

1,在servlet-dispatcher.xml中添加代码

<bean
id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
/>

也可以根据需求添加相关属性

<property name="maxUploadSize" value="2097152"></property> 
 

2，添加依赖jar文件

		<dependency>
			<groupId>commons-io</groupId>
			<artifactId>commons-io</artifactId>
			<version>2.4</version>
		</dependency>
		<dependency>
			<groupId>commons-fileupload</groupId>
			<artifactId>commons-fileupload</artifactId>
			<version>1.3.1</version>
		</dependency>

3、编写uploadController

    @RequestMapping(value="/upload",method=RequestMethod.POST)
    public String processUpload(@RequestParam("name") String name,
    		@RequestParam("file") MultipartFile file) throws IOException {
      	log.info("File '" + file.getOriginalFilename() + "' uploaded successfully");
      	if (!file.isEmpty()) {
            try {
                byte[] bytes = file.getBytes();
                BufferedOutputStream stream =
                        new BufferedOutputStream(new FileOutputStream(new File(name)));
                stream.write(bytes);
                stream.close();

                return "You successfully uploaded " + name + "!";
            } catch (Exception e) {
                return "You failed to upload " + name + " => " + e.getMessage();
            }
        } else {
            return "You failed to upload " + name + " because the file was empty.";
        }
    }  

4、使用RestClient测试上传
