Question

我尝试使用简单的fileuploader上传文件，但我一直收到此错误：

org.apache.tomcat.util.http.fileupload.FileUploadBase$InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is application/x-www-form-urlencoded

        <f:facet name="footer">

            <p:commandButton actionListener="#{objave.spremiSliku()}"
                             value="Spremi"
                             icon="ui-icon-disk"
                             ajax="false"/>
        </f:facet>
    </h:panelGrid>
</h:form>

Objave.java

private UploadedFile file;

public String spremiSliku() {
    System.out.println(file.getFileName());
    return "";
}

如果我使用高级fileUploader，那么一切正常，但我需要简单的fileUploader，并且无法使其工作。我是PrimeFaces菜鸟，所以我不知道如何解决这个问题。有人可以帮我这个吗？

请求不包含multipart / form-data或multipart / mixed流
