Question

我正在尝试使用JavaScript在Spring Boot上做一些项目，但我有很多错误。他们在这里：

org.springframework.web.method.annotation.MethodArgumentTypeMismatchException：无法将[java.lang.String]类型的值转换为所需类型 [INT];嵌套异常是java.lang.NumberFormatException：用于输入 string：“filterByData” 引起：java.lang.NumberFormatException：对于输入字符串： “filterByData”

我在项目中找不到这个“filterByData”，我给出了什么参数，比如int insteed of String。我的实体：

我的基本CRUD方法在没有“过滤器”的情况下正常工作，每次都会出现这种错误。有人可以告诉我我做错了什么吗？感谢。

public abstract class AbstractUserController {

    @Autowired
    private UserService service;

    public List<User> getAll() {
        return service.getAll();
    }

    public User get(int id){
        return service.get(id);
    }

    public User create(User user) {
        user.setId(null);
        return service.save(user);
    }

    public void delete(int id){
        service.delete(id);
    }

    public void update(User user, int id) {
        user.setId(id);
        service.update(user);
    }

    public void update(UserDTO userDTO) {
        service.update(userDTO);
    }

    public User getByLogin(String login) {
        return service.getByLogin(login);
