由于Bozho提出的解决方案不能完全满足我的需求，因此我编写了一个过滤器，该过滤器完全可以满足我的需求。不知道将来是否会发生任何问题，但是在此之前，请随时使用我的实现：
@Servicepublic class RedirectFilter implements Filter {@Overridepublic void init(FilterConfig filterConfig) throws ServletException {}@Overridepublic void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { String queryString = ((HttpServletRequest) request).getQueryString(); if (queryString != null) { RedirectAwareResponseWrapper res = new RedirectAwareResponseWrapper((HttpServletResponse) response); chain.doFilter(request, res); if (res.isRedirected()) { ((HttpServletResponse) response).sendRedirect(res.getLocation() + "?" + queryString); } } else { chain.doFilter(request, response); }}@Overridepublic void destroy() {}class RedirectAwareResponseWrapper extends HttpServletResponseWrapper { private boolean redirected = false; private String location; public RedirectAwareResponseWrapper(HttpServletResponse response) { super(response); } @Override public void sendRedirect(String location) throws IOException { redirected = true; this.location = location; //importANT: don't call super() here } public boolean isRedirected() { return redirected; } public String getLocation() { return location; }}}
