        <input type="file" name="myFile">
        <input type="submit" value="Submit">
    </form>
</body>

上面的代码在编译时抛出 java.lang.NoSuchMethodError。我不明白上面代码中的 blobstoreService 是什么？

您缺少标题

<%@ page import="com.google.appengine.api.blobstore.BlobstoreServiceFactory" %> <%@ page import="com.google.appengine.api.blobstore.BlobstoreService" %>

<% BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); %>

上传测试" method="post" enctype="multipart/form-data">
