Question

我有以下图片裁剪器：

<h:form>
    <p:imageCropper id="imageDialog" 
                    value="#{petForm.croppedImage}" 
                    image="#{petForm.uploadedFilename}" 
                    maxSize="#{petForm.width},#{petForm.height}" 
                    minSize="#{petForm.width},#{petForm.height}" />
</h:form>

Chrome和Opera中的一切都运行良好。但是，当我使用FireFox时，我的GlassFish 4.0服务器上出现以下异常：

这是如何引起的？如何解决？

Answer 1

我已经解决了。到目前为止，在我的问题中提供的信息中看不到原因。我使用反斜杠\作为图像URI，基本上如下所示：

<p:imageCropper value="\resources\image.jpg" />

Chrome和Opera似乎默默地将反斜杠\切换为斜杠/并获取正确的资源。 FireFox没有这样做，并且在下载图像时仍然使用反斜杠。

在我更改了如下图像URI后，一切正常。

<p:imageCropper value="/resources/image.jpg" />

p：imageCropper仅在FireFox上导致“java.io.CharConversionException：无效的URI字符编码”
