1 @RequestMapping("alipayforward") 2 public ModelAndView alipayforward(HttpServletRequest req, HttpServletResponse resp) throws Exception { 3 String contNo =req.getParameter("contNo"); 4 logger.info("访问/downloadRequestElecCont.action"); 5 String url = "redirect:http://baidu.com/downloadRequestElecCont.action?contNo="+contNo; 6 return new ModelAndView(url); 7 }
1 @RequestMapping("alipayforward/{contNo}") 2 public void alipayforward(@PathVariable("contNo") String contNo, HttpServletRequest req, HttpServletResponse resp) throws Exception { 3 //String contNo =req.getParameter("contNo"); //保单号 4 logger.info("访问/downloadRequestElecCont.action"); 5 resp.sendRedirect("http://baidu.com/downloadRequestElecCont.action?contNo="+contNo); 6 }
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
1 @RequestMapping("alipayforward") 2 public String alipayforward(@RequestParam("contNo") String contNo, HttpServletRequest req, HttpServletResponse resp) throws Exception { 3 //String contNo =req.getParameter("contNo"); //保单号 4 logger.info("访问/downloadRequestElecCont.action"); 5 return "redirect:http://baidu.com/downloadRequestElecCont.action?contNo="+contNo; 6 }
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
1 @RequestMapping(params = "action=alipayforward") 2 public String alipayforward(Map modelMap){ 3 modelMap.put("userName", "呵呵"); 4 modelMap.put("password", "123456"); 5 modelMap.put("age", "25"); 6 return "redirect:http://localhost:8088/era/user/alipayforward4?modelMap="+modelMap; 7 }
另一个项目用实体类对象接收
1 @RequestMapping("alipayforward4") 2 public void alipayforward4(User user, HttpServletRequest req) throws Exception { 3 System.out.println(user.getPassword()); 4 String modelMap = req.getParameter("modelMap"); 5 System.out.println(modelMap); 6 }
