SpringMvc请求参数的获取
1.通过HttpServletRequest获取
@RequestMapping("/deleteUser")
public ModelAndView deleteUser(HttpServletRequest request, HttpServletResponse response) throws IOException {
System.out.println("删除用户..."+request.getParameter("id"));
response.getWriter().write("hello");
return null;
}
2.通过方法的形参获取
@RequestMapping("/deleteUser")
public ModelAndView deleteUser(HttpServletRequest request, HttpServletResponse response,Integer id) throws IOException {
System.out.println("删除用户..."+id);
response.getWriter().write("hello");
return null;
}
请求的细化
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping("/find")
public ModelAndView find() {
System.out.println("findUser....");
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("/index.jsp");
modelAndView.addObject("username", "admin111");
return modelAndView;
}
}
