我正在将wicket 1.4迁移到6到1.5。我遇到了一个无法解决的问题。在wicket 1.4我曾经有过(注意:是的,我确实有detach
)
public class TempFileResourceRequestTarget extends ResourceStreamRequestTarget implements Serializable {
@Override
protected void configure(final RequestCycle requestCycle, final Response response,
final IResourceStream resourceStream) {
super.configure(requestCycle, response, resourceStream);
((WebResponse)response).getHttpServletResponse().setHeader("Cache-Control","");
((WebResponse)response).getHttpServletResponse().setHeader("Pragma","");
}
在wicket 1.5 / 6中,我将其改为:
public class TempFileResourceRequestTarget extends ResourceStreamRequestHandler implements Serializable {
@Override
protected void configure(ResourceStreamResource resource) {
super.configure(resource);
((HttpServletResponse)resource).setHeader("Cache-Control","");
((HttpServletResponse)resource).setHeader("Pragma","");
}
}
我很绝望,并试图找到任何包含setHeader()的东西 - 我相信我在迁移指南中找到了它或类似的东西。无论如何这不起作用。我该如何设置?在renderHead?没有线索。提前谢谢。
答案 0 :(得分:1)
ResourceStreamResource
未实施HttpServletResponse
。
您可以使用ResourceStreamResource#setCacheDuration(Duration.NONE)
禁用缓存。
它将为您执行以下操作:
public void disableCaching() {
this.setDateHeader("Date", Time.now());
this.setDateHeader("Expires", Time.START_OF_UNIX_TIME);
this.setHeader("Pragma", "no-cache");
this.setHeader("Cache-Control", "no-cache, no-store");
}
这就是你想要的吗?
