There are two main steps:

主要有兩個步驟:

1) add an instance of multipart resolver to the Spring context

1)將一個多部分解析器的實例添加到Spring上下文中

class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

2) add a handler method

2)添加一個處理程序方法

// I assume that your controller is annotated with /ajaxSaveMedia.do

@RequestMapping(method = RequestMethod.POST)

public @ResponseBody String doUpload(@RequestParam("file") MultipartFile multipartFile) {

return "Uploaded: " + multipartFile.getSize() + " bytes";

}

要從org.springframework.web.multipart.MultipartFile獲取java.io.File的實例:

File file = new File("my-file.txt");

multipartFile.transferTo(file);
