我的代码中有这个错误。
这是我的UserController

package com.inn.project.controllers;

import com.inn.project.models.User;
import com.inn.project.services.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@CrossOrigin
public class UserController {
    @Autowired
    private UserService userService;

    @GetMapping("/users")
    public List<User> getUsers(){
        return userService.getUsers();
    }
    @PostMapping("/users/addnew")
    public void addUser(@RequestBody User user){
        userService.addUser(user);
    }
    @PutMapping("/users/{id}/edit")
    public void updateUser(@PathVariable("id") Long id, @RequestBody User user){
        userService.updateUser(user);
    }
    @DeleteMapping("/users/{id}/delete")
    public void deleteUser(@PathVariable("id") Long id){
        userService.deleteUser(id);
    }
}

型
AuthController

package com.inn.project.controllers;

import com.inn.project.dtos.UserDto;
import com.inn.project.services.UserService;
import lombok.RequiredArgsConstructor;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequiredArgsConstructor
public class AuthController {
    private final UserService userService;

    @PostMapping("/login")
    public ResponseEntity<UserDto> login(@RequestBody Credentials credentials){
        UserDto user = userService.login(credentials);
        return ResponseEntity.ok(user);
    }
}

型
这是用户模型

package com.inn.project.models;

import jakarta.persistence.*;
import lombok.Data;
import lombok.NoArgsConstructor;

@NoArgsConstructor
@Entity
@Data
@Table(name = "User")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "first_name")
    private String firstName;

    @Column(name = "last_name")
    private String lastName;

    @Column(name = "password")
    private String password;

    private String location;
    private String login;

    @Column(name = "notifications")
    private boolean notifications;

}

型
这是Mapper：

package com.inn.project.mappers;

import com.inn.project.dtos.UserDto;
import com.inn.project.models.User;
import org.mapstruct.Mapper;

@Mapper(componentModel = "spring")
public interface UserMapper {
    UserDto toUser(User user);
}

型
这是UserDto：

package com.inn.project.dtos;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class UserDto {
    private Long id;
    private String firstName;
    private String lastName;
    private String login;
    private String password;
}

型
这里是UserService

package com.inn.project.services;

import com.inn.project.controllers.Credentials;
import com.inn.project.dtos.UserDto;
import com.inn.project.exceptions.AppException;
import com.inn.project.mappers.UserMapper;
import com.inn.project.models.User;
import com.inn.project.repositories.UserRepository;
import lombok.RequiredArgsConstructor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;

import java.nio.CharBuffer;
import java.util.List;

@Service
@RequiredArgsConstructor
public class UserService {
    private final UserRepository userRepository;
    private final PasswordEncoder passwordEncoder;
    private final UserMapper userMapper;
    public List<User> getUsers(){
        return userRepository.findAll();
    }
    public UserDto login(Credentials credentials){
        User user = userRepository.findByLogin(credentials.login())
                .orElseThrow(()-> new AppException("Uknown user", HttpStatus.NOT_FOUND));
        if (passwordEncoder.matches(CharBuffer.wrap(credentials.password()),
        user.getPassword()))
        {
            return userMapper.toUser(user);
        }
        throw new AppException("Invalid password", HttpStatus.BAD_REQUEST);

    }
    public void addUser(User user){
        userRepository.save(user);
    }
    public void updateUser(User user){
        userRepository.save(user);
    }
    public void deleteUser(Long id){
        userRepository.deleteById(id);
    }
}

我试图找到像我这样的问题，但最后我放弃了，因为没有。我写这段代码的基础上，本教程：https://www.youtube.com/watch?v=YUqi1IjLX8I

您的问题是在使用mapstruct时没有真正阅读文档。
Map结构体非常像lombok，它在编译时生成代码，就像在创建一堆代码让你Map一样，lombok在编译时生成一堆getter和setter。
他们的github readme中的示例清楚地解释了如何使用它。

...
<properties>
    <org.mapstruct.version>1.5.5.Final</org.mapstruct.version>
</properties>
...
<dependencies>
    <dependency>
        <groupId>org.mapstruct</groupId>
        <artifactId>mapstruct</artifactId>
        <version>${org.mapstruct.version}</version>
    </dependency>
</dependencies>
...
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.mapstruct</groupId>
                        <artifactId>mapstruct-processor</artifactId>
                        <version>${org.mapstruct.version}</version>
                    </path>
                </annotationProcessorPaths>
            </configuration>
        </plugin>
    </plugins>
</build>
...

您还没有将注解处理器添加到编译器中，因此没有任何东西阅读您的mapstruct注解，并生成所需的代码，因此当服务器启动时，它会抱怨缺少了一些东西。
请阅读有关如何使用mapstruct的说明
