目前我正在使用zkoss,java和maven。我的应用程序中的一个功能是上传文件。
当我通过上传一个非常大的文件对此功能进行一些测试时,我收到了一条提示错误消息,其中说 “请求被拒绝,因为其大小(8356577)超出了配置的最大值(1024000)”
在我做了几次调试之后,我发现提示消息来自org.apache.commons.fileupload.FileUploadBase,它来自我的一个maven依赖项。
现在,我想将错误消息更改为其他内容。有没有解决方法怎么做?我更喜欢不重新编译库的方式。非常感谢。

这是我的web.xml。我做错什么了吗?再次感谢。

答案 0 :(得分:0)
您可以从org.zkoss.zk.au.http.AuUploader
延伸并覆盖handleError(Throwable)
方法:
public class MyUploader extends AuUploader {
@Override
protected String handleError(Throwable ex)
{
return "mymessage";
}
}
然后你必须在你的web.xml中配置这个扩展:
配置
<servlet>
<servlet-class>org.zkoss.zk.au.http.DHtmlUpdateServlet</servlet-class>
<!-- extentions here -->
</servlet>
添加:
<init-param>
<param-name>processor0</param-name>
<param-value>/upload=uploader.MyUploader</param-value>
</init-param>
可能processor0
必须更改为extention0
,具体取决于您的ZK版本。 processor0
被证实与ZK 7合作。
可以找到有关此问题的ZK文档here。
