Question

我正在使用Spring 3.1.1和tomcat 5.5.31

cardproducer.jsp文件中的invoke方法：

window.location.href = "${pageContext.request.contextPath}/deleteCardProducer/"
                + id + ".html";

控制器：

@RequestMapping("/deleteCardProducer/{id}")
public String delete(@PathVariable("id") String id, Model model,RedirectAttributes att,HttpServletRequest request)
        throws Exception {
    if(service.deleteCardProducer(id)){
        return getCardProducerList(model,request);
    }else{
        request.setAttribute("errorMessage", resource.getMessage(
                "error.relevantCardProducer", new Object[] {},
                LocaleContextHolder.getLocale()));
        return "redirect:cardProducer.html";
    }
}

删除后应列出所有cardProducers：

@RequestMapping("/cardProducer")
public String getCardProducerList(Model model,HttpServletRequest request) {
    model.addAttribute("cardProducerList", service.getAllProducer());
    try {
        if (request.getParameter("errorMessage")==null) {
            return "cardproducer/cardProducer";
        }

            String errorMessage=new String(request.getParameter("errorMessage").getBytes("ISO-8859-1"), "GBK");
            model.addAttribute("errorMessage",errorMessage);
            log.info("request.getParameter(errorMessage):"+errorMessage);
        } catch (UnsupportedEncodingException e) {
            log.error("errors"+e.getMessage());
        }
        return "cardproducer/cardProducer";

日志信息显示请求URL为cardpro，如下所示：

正确的事情是删除cardProducer然后显示所有这些。它会导致无限循环。

Answer 1

你可以尝试 - modelAndView.setViewName（“redirect：/ cardProducer”）;

//在我的项目中，我使用 Tiles 进行模板化

Answer 2

我认为你的重定向不会回到root。当您通过"redirect:cardProducer.html"重定向时，我猜测它只是将其附加到您当前的URI，产生类似"/deleteCardProducer/cardProducer.html"的内容。它正在重定向到这个，由删除控制器拾取，并一次又一次地重定向。

相反，您需要重定向回root。像"redirect:/cardProducer.html"这样的开头斜线的东西。

您应该能够在浏览器中打开控制台，看看位置标头值是什么（重定向URI）。

Spring MVC中的重定向发生无限循环
