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
后台提示：
