@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
