1、转发
方式一:使用 "forword" 关键字(不是指java关键字),注意:类的注解不能使用@RestController 要用@Controller
@RequestMapping(value="/test/test01/{name}" , method = RequestMethod.GET) public String test(@PathVariable String name) { logger.info("controller类中方法的参数:" + name); HelloService helloService = new HelloService(); helloService.helloService(); return "forword:/ceng/hello.html"; }
方式二:使用servlet 提供的API,注意:类的注解可以使用@RestController,也可以使用@Controller
@RequestMapping(value="/test/test01/{name}" , method = RequestMethod.GET) public void test(@PathVariable String name, HttpServletRequest request, HttpServletResponse response) throws Exception { logger.info("controller类中方法的参数:" + name); HelloService helloService = new HelloService(); helloService.helloService(); request.getRequestDispatcher("/ceng/hello.html").forward(request,response); }
2、重定向
方式一:使用 "redirect" 关键字(不是指java关键字),注意:类的注解不能使用@RestController,要用@Controller
@RequestMapping(value="/test/test01/{name}" , method = RequestMethod.GET) public String test(@PathVariable String name) { logger.info("controller类中方法的参数:" + name); HelloService helloService = new HelloService(); helloService.helloService(); return "redirect:/ceng/hello.html"; }
方式二:使用servlet 提供的API,注意:类的注解可以使用@RestController,也可以使用@Controller
@RequestMapping(value="/test/test01/{name}" , method = RequestMethod.GET) public void test(@PathVariable String name, HttpServletResponse response) throws IOException { logger.info("controller类中方法的参数:" + name); HelloService helloService = new HelloService(); helloService.helloService(); response.sendRedirect("/ceng/hello.html"); }
使用API进行转发时,一般会在url之前加上:request.getContextPath()
