谷歌应用引擎不支持 FileOutputStream [英] google appengine not supporting FileOutputStream

问题描述

我正在尝试写入 Google Appengine 中的文件，但它给出错误消息 java.io.FileOutputStream is not supported by Google App Engine's Java runtime environment

I am trying to write to a file in Google appengine but it giving a error message java.io.FileOutputStream is not supported by Google App Engine's Java runtime environment

即使我导入了

import java.io.File;
import java.io.FileInputStream;

import java.io.FileOutputStream;
import java.io.IOException;

推荐答案

好吧，这不是 Java 编译器错误.此类是 Google App Engine 中的受限 API，您不得使用它.

Well it's not a java compiler error. This class is a restricted API in Google App Engine you are not allowed to use it.

在此处阅读有关 GAE Java 运行时环境和限制的信息:http://code.google.com/appengine/docs/java/runtime.html

Read about the GAE Java Runtime Environment and restrictions here: http://code.google.com/appengine/docs/java/runtime.html

最接近 GAE 文件存储的是 Blobstore API:http://code.google.com/appengine/docs/java/blobstore/

The closest you will get to file storage on GAE is the Blobstore API: http://code.google.com/appengine/docs/java/blobstore/

如果您需要在代码中创建文件 GAE 不是适合您的平台.

If you need to create files in code GAE is not an appropriate platform for you.
