use*_*935 37 url spring jsp web-applications request
我正在尝试在Spring webapp中的JSP中获取正确的当前URL.我正在尝试在JSP文件中使用以下片段:
${pageContext.request.requestURL}
问题是返回的URL包含UrlBasedViewResolver定义的前缀和后缀.例如,正确的URL是:
但返回的是:
Pau*_*nis 48
最好的方法是使用这样的EL:
${requestScope['javax.servlet.forward.request_uri']}
也许你正在寻找类似的东西:
<%= new UrlPathHelper().getOriginatingRequestUri(request) %>
这不是那么优雅,但解决了我的问题.
