引用这种类？你是认真的吗？

org.springframework.web.multipart.MultipartHttpServletRequest

TempFile 使用这个的话，会让我获取到的不能转MultipartFile

nutz没有MultipartFile这个类

嗯嗯所以我使用到TempFile 是能够获取到，但是我不知道怎么在里面java七牛云上传了，不是文档中的那种js上传的。

仔细去看官方文档，人家各种上传方式都讲的非常清楚

你想要的是TempFile获得File实例吧？.getFile方法就行啦

qq_91afbf68 7楼•2057天前

我看到这个文档是这种方式，是可以用获取@Param("..")NutMap nm来接收，也能ServletContext 对象注入 MyUtils
https://blog.csdn.net/mamacmm/article/details/83914479

ioc文件夹下，添加一个名称为 myUpload.js 的文件（名称无所谓，随便起），里面的内容如下：

 

var myUploadIoc = {
	utils : {     
		type : 'com.mm.util.MyUtils',     
		fields : {         
			sc : {app:'$servlet'}   // 将 ServletContext 对象注入 MyUtils
		}
	},
	tmpFilePool : {     
		type : 'org.nutz.filepool.NutFilePool',     // 临时文件最大个数为 1000 个     
		args : [ {java:'$utils.getPath("/tmp")'}, 1000 ]    
	},
	uploadPicFileContext : { 
		type : 'org.nutz.mvc.upload.UploadingContext',     
		singleton : false,     
		args : [ { refer : 'tmpFilePool' } ],
		fields : {
			// 是否忽略空文件, 默认为 false         
			ignoreNull : true, 
			// 单个文件最大尺寸(大约的值，单位为字节，即 1048576 为 1M)         
			maxFileSize : 1048576,         // 正则表达式匹配可以支持的文件名         
			nameFilter : '^(.+[.])(gif|jpg|png)$'
		}
	},
	myPicUpload : {     
		type : 'org.nutz.mvc.upload.UploadAdaptor',     
		singleton : false,     
		args : [ { refer : 'uploadPicFileContext' } ]  
	}
};
 

注意：

 

com.mm.util.MyUtils 是自己定义的一个工具类，为了得到上传地址，内容如下：

 

package com.mm.util;
 
import javax.servlet.ServletContext;
 
/**
 * 用于上传ioc : myUpload.js 
 *
 */
public class MyUtils {
	private ServletContext sc;      
	public String getPath(String path) {         
		return sc.getRealPath(path);     
	} 
}
 

tmpFilePool 是Nutz的文件池；

java:'$utils.getPath("/tmp")'  这个是指明了上传的图片的地址是：项目根目录下的tmp目录下；

gif|jpg|png  限制了上传文件的格式。

/**
 * 添加照片
* @param albumId 相册ID
* @param req 
*/
@At("/photo/pho/addPhoto")
@Ok("fm:/common/execute_result.ftl")
@AdaptBy(type = UploadAdaptor.class, args = { "ioc:myPicUpload" })
public void addPhoto(@Param("..")NutMap nm,HttpServletRequest req){
	//log.info("NutMap:"+nm);
	TempFile tf = (TempFile)nm.get("photoFile");
	File f = tf.getFile();
	//FieldMeta meta = tf.getMeta();
	//String oldName = meta.getFileLocalName();
	//log.info("文件绝对路径："+f.getAbsolutePath()+"，原来的名称："+oldName);
		
	String str = f.getPath();
	int one = str.indexOf(Constants.UPLOAD_FILE_DIRECTORY_NAME);
	str = str.substring(one);
	//log.info("文件的相对路径："+str);
 
	long albumId = (long)nm.getInt("albumId");
	String photoName = (String)nm.get("photoName");
	String description = (String)nm.get("description");
	Photo photo = new Photo();
	photo.setAlbumId(albumId);
	photo.setPhotoName(photoName);
	photo.setDescription(description);
	photo.setCreateDate(TimeUtil.getNowTime("yyyy-MM-dd"));
//	photo.setPhotoUrl(f.getAbsolutePath());
	photo.setPhotoUrl(str);
	getServiceManager().getPhotoService().insert(photo);
		
	setExecuteResult(null);
	addMessage("添加照片成功!");
	addRedirURL("返回", "@back");
	addRedirURL("照片列表", "photoList.html?albumId="+String.valueOf(albumId));
	req.setAttribute(EXECUTE_RESULT, getExecuteResult());
}

可以那么玩？

感谢大佬，之前没有认真看七牛云文档
