然后写个controller层 @Controller public class MyController { @Resource private IUserService service; @RequestMapping("/fun") public String fun(Map mm){ List<User> list = service.query(); System.out.println(list); mm.put("list", list); return "hello"; } @RequestMapping("/delete") @ResponseBody public String delete(){ int row = 0 ; row = service.delete(19); String msg = ""; if (row == 1) { msg = "ok"; }else { msg ="no"; } System.out.println(msg); return msg; } @RequestMapping("/insert") @ResponseBody public String insert(){ int row = 0 ; row = service.insert(new User("a","aaa",17,"gaag")); String msg = ""; if (row == 1) { msg = "成功"; }else { msg ="失败"; } return msg; } @RequestMapping("/update") @ResponseBody public String update(){ int row = 0 ; row = service.update(new User(20,"aa","aaa",19,"gaag")); String msg = ""; if (row == 1) { msg = "ok"; }else { msg ="no"; } System.out.println(msg); return msg; }
