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()
