SpringMVC的ajax的使用及返回中文亂碼問題

（一）SpringMVC Ajax使用

$.ajax({
          url: "http://localhost:8080/demo/user/login",
          type: "POST",
          data: "name"="admin",
          async: false,
          success: function(data) {
            alert("success");
          },
          error: function() {
            alert("error");
          }
        });

Controller

@Controller  
@RequestMapping("/user/*")  
public class LoginController {  
    @RequestMapping(value="login")  
    public @ResponseBody String login(HttpServletRequest request,HttpServletResponse response){ 
        String name =request.getParameter("name")

        System.out.println();
          
        return name;  
    }
