java - Spring MVC 中的重定向

Question

为什么我不能让它在我的 Controller 中工作

@RequestMapping(method = RequestMethod.POST)
public String onSubmit(
    Model model,
    @ModelAttribute("form") Form form,
    BindingResult result, HttpServletRequest request)
    throws IOException, WriteException, BiffException {

    if (result.hasErrors()) {
        return "redirect:index.html";
    }

 }

我明白了:

javax.servlet.ServletException: Could not resolve view with name 'redirect:index.html' in servlet with name 'dispatcher'
org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1042)
org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:798)
org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716)
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644)
org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:560)
javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:390)

我以前有这个工作。为什么不是现在？

试试这个，如果你正确配置了 View 解析器，它应该可以工作

 return "redirect:/index.html";
