用法

@Controller
public class UserController {
    private static final Logger LOGGER = LoggerFactory.getLogger(UserController.class);
    @Resource
    private UserService userService;

    @URL(value = {"/", "/index"}, method = {HttpMethod.GET, HttpMethod.POST})
    public String list(Map<String, Object> map) {
        map.put("userList", userService.listUsers());
        return "list";
    }

    @URL("home")
    public String home() {
        return "forward:/";
    }

    @URL(value = "/add", method = HttpMethod.GET)
    public String addPage() {
        return "add";
    }

    @URL(value = "/add", method = HttpMethod.POST)
    public String addUser(Map<String, String> map, @Param("name") String name) {
        //String name = map.get("name");  // map 里有所有参数 或者从方法中标有 @Param 的参数获取
        String email = map.get("email");
        String note = map.get("note");
        if (name == null || email == null) {
            map.put("error", "用户名及电子邮件是必填项");  // map 还充当返回结果的 Model 的角色
            return "add";
        }
        User user = new User().setName(name).setEmail(email).setNote(note);
        userService.saveUser(user);
        return "redirect:/";
    }
     // ... 
}
