从Spring MVC中的控制器操作重定向到外部URL

你可以通过两种方式来实现。

第一：

@RequestMapping(value = "/redirect", method = RequestMethod.GET)public void method(HttpServletResponse httpServletResponse) {    httpServletResponse.setHeader("Location", projectUrl);    httpServletResponse.setStatus(302);}

第二：

@RequestMapping(value = "/redirect", method = RequestMethod.GET)public ModelAndView method() {    return new ModelAndView("redirect:" + projectUrl);}
