2.后台接受前台请求，并发送相应
@Controller
public class HelloController {
@GetMapping("/abc2")
@ResponseBody
public Map<String,Object> hello2(@RequestParam("user")String user){
System.out.println(user);
List<String> list = new ArrayList<>();
list.add("a");
list.add("b");
list.add("c");
Map<String,Object> map = new HashMap<>();
map.put("1","王二小");
map.put("2","刘明");
map.put("3","张三");
return map;
}
}
