关于上传的问题

上传后，文件名字变为01，02，03。。。。。。
上传的实际路径变成了这样： \WEB-INF\tmp\user_avatar\00\00\00\00\00\00\00

    /**
	 * 上传测试
	 * @return
	 */
	@At("/up")
	@AdaptBy(type = UploadAdaptor.class, args = { "${app.root}/WEB-INF/tmp/user_avatar", "8192", "utf-8", "20000", "102400"} )
	public View up(@Param("photo") TempFile[] tfs){
		return new ViewWrapper(new JspView("views/front/home"),null);
	}

tfs可以获取到原来文件的信息

@kerbores

@At("/up")
	@AdaptBy(type = UploadAdaptor.class, args = { "${app.root}/WEB-INF/tmp/user_avatar", "8192", "utf-8", "20000", "102400"} )
	public View up(@Param("photo") TempFile tf){
		System.out.println(tf.getFile());//C:\Users\Emay\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp3\wtpwebapps\...
		
		System.out.println(tf.getMeta().getFileLocalPath());//名字,开题报告.doc
		System.out.println(tf.getMeta().getFileLocalName());//名字,开题报告.doc
		System.out.println(tf.getMeta().getContentDisposition());//form-data

@kerbores 我存的文件路径不是这个注解上的 ${app.root}/WEB-INF/tmp/user_avatar

实际上的路径是这个：C:\Users\Emay\workspace.metadata.plugins\org.eclipse.wst.server.core\tmp3\wtpwebapps\designsource\WEB-INF\tmp\user_avatar\00\00\00\00\00\00\00\09.jpg

多了一堆\00\00\00\00\00\00\00\

那是"临时文件", 自行Files.copy到需要的路径去.

哎呦哥哥(qq_999005dc) 5楼•2989天前

@wendal 他为什么没有走注解上面的路径呢，"${app.root}/WEB-INF/tmp/user_avatar"

${app.root}的值就是serveltContext.getRealPath("/")的值, 在eclipse+tomcat环境下也就是"C:\Users\Emay\workspace.metadata.plugins\org.eclipse.wst.server.core\tmp3\wtpwebapps\designsource"这种路径
这是临时目录

@wendal 哦哦，谢谢

@wendal 做了个更简单的测试

@At("/upload")
	@AdaptBy(type = UploadAdaptor.class, args = { "${app.root}/WEB-INF/tmp", "8192", "utf-8", "20000", "102400" })
	@POST
	public void upload(@Param("file") TempFile tf) {

	}

报错如下，只想上传个文件

@qq_c1bab051 仔细看报错信息

老司机(qq_c1bab051) 12楼•2747天前

@wendal 所以啊，这个enctype='multipart/form-data' 应该放在哪啊？我哪里漏掉了？😭

@qq_c1bab051 form的一个属性，跟method一样

老司机(qq_c1bab051) 14楼•2745天前

@wendal 那要在service里面实现${app.root}，获取项目更目录，还只能用ServletContext.getRealPath("/")？nutz有木有提供啥简便方法啊？
