（1）通过ModelAndView跳转

@RequestMapping("alipayforward") public ModelAndView alipayforward(HttpServletRequest req, HttpServletResponse resp) throws Exception { String contNo =req.getParameter("contNo"); logger.info("访问/downloadRequestElecCont.action"); String url = "redirect:http://baidu.com/downloadRequestElecCont.action?contNo="+contNo; return new ModelAndView(url); } |
（2）通过HttpServletResponse跳转

@RequestMapping("alipayforward/{contNo}") public void alipayforward(@PathVariable("contNo") String contNo, HttpServletRequest req, HttpServletResponse resp) throws Exception { //String contNo =req.getParameter("contNo"); //保单号 logger.info("访问/downloadRequestElecCont.action"); resp.sendRedirect("http://baidu.com/downloadRequestElecCont.action?contNo="+contNo); } |
（3）通过redirect返回String类型跳转，注意这种方法不允许Spring控制器用@RestController注解，因为@RestController相当于类中的所有方法都标注了@ResponseBody，这些方法不会返回一个视图，而是返回一个json对象，这样的话只是在页面上打印出字符串，而不跳转。控制器用@Controller注解即可

@RequestMapping("alipayforward") public String alipayforward(@RequestParam("contNo") String contNo, HttpServletRequest req, HttpServletResponse resp) throws Exception { //String contNo =req.getParameter("contNo"); //保单号 logger.info("访问/downloadRequestElecCont.action"); return "redirect:http://baidu.com/downloadRequestElecCont.action?contNo="+contNo; } |
下面是关于传参问题
重定向传参为get方式，如果传参数较多，可以封装到map或modelMap中

@RequestMapping(params = "action=alipayforward") public String alipayforward(Map modelMap){ modelMap.put("userName", "呵呵"); modelMap.put("password", "123456"); modelMap.put("age", "25"); return "redirect:http://localhost:8088/era/user/alipayforward4?modelMap="+modelMap; } |
另一个项目用实体类对象接收

@RequestMapping("alipayforward4") public void alipayforward4(User user, HttpServletRequest req) throws Exception { System.out.println(user.getPassword()); String modelMap = req.getParameter("modelMap"); System.out.println(modelMap); } |
