Spring Boot - 不是托管类型，创建 bean 时出错

[英]Spring Boot - Not a managed type, Error creating bean

 原文  2022-12-22 11:36:22  7   2    java/ spring/ spring-boot/ spring-security/ javabeans

问题描述

我想知道如何在我的 Spring Boot 项目中修复这些错误，我创建了一个非常简单的项目，使用基于 Spring Security 的登录/注册，但我不知道如何修复这些东西，我已经尝试了所有具有相同问题的建议，但这些都没有帮助我:(

提前致谢！

我项目中的所有代码：

安全配置

@Configuration
@EnableWebSecurity
public class SecurityConfig {
    @Autowired
    private DataSource dataSource;
    
    @Bean
    public UserDetailsService employeeDetailsService() {
        return new EmployeeDetailsServiceImpl();
    }
    
    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
    
    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
        authProvider.setUserDetailsService(employeeDetailsService());
        authProvider.setPasswordEncoder(passwordEncoder());
        
        return authProvider;
    }

    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider());
    }

    @Bean
    public void filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
            .requestMatchers("/users").authenticated()
            .anyRequest().permitAll()
            .and()
            .formLogin()
                .usernameParameter("email")
                .defaultSuccessUrl("/users")
                .permitAll()
            .and()
            .logout().logoutSuccessUrl("/").permitAll();
    }
    
    
}

应用控制器

@Controller
public class AuthController {

    @Autowired
    private EmployeeRepository employeeRepository;
    
    @GetMapping("")
    public String viewHomePage() {
        return "home";
    }
    
    @GetMapping("/register")
    public String showRegistrationForm(Model model) {
        model.addAttribute("employee", new Employee());
        
        return "registration";
    }
    
    @PostMapping("/process_register")
    public String processRegister(Employee employee) {
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        String encodedPassword = passwordEncoder.encode(employee.getPassword());
        employee.setPassword(encodedPassword);
        
        employeeRepository.save(employee);
        
        return "register_success";
    }

}

员工实体

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@ToString
@Entity
@Table(name = "employees")
public class Employee {

    @Id
   // @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "first_name")
    private String firstName;
    
    @Column(name = "last_name")
    private String lastName;
    
    @Column(name = "department")
    private String department;
    
    @Column(name = "phone_number")
    private String phoneNumber;

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

资料库

@Repository
public interface EmployeeRepository extends JpaRepository<Employee, Long>{
    @Query("SELECT u FROM Employee u WHERE u.department = :department")
    public Employee findByDepartment(String department);
}

员工详情

public class EmployeeDetails implements UserDetails {

    private Employee employee;
    
    public EmployeeDetails(Employee employee) {
        this.employee = employee;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return null;
    }

    @Override
    public String getPassword() {
        return employee.getPassword();
    }

    @Override
    public String getUsername() {
        return employee.getEmail();
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
    
    public String getFullName() {
        return employee.getFirstName() + " " + employee.getLastName();
    }

EmployeeDetails服务实现

@Service
public class EmployeeDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private EmployeeRepository employeeRepo;
    
    @Override
    public UserDetails loadUserByUsername(String department) throws UsernameNotFoundException {
        Employee employee = employeeRepo.findByDepartment(department);
        if (employee == null) {
            throw new UsernameNotFoundException("User not found");
        }
        return new EmployeeDetails(employee);
    }
}

启动应用程序

@SpringBootApplication
public class PersonaldpslvivApplication {

    public static void main(String[] args) {
        SpringApplication.run(PersonaldpslvivApplication.class, args);
    }

}

您在存储库中的查询应该是这样的：

@Query("SELECT u FROM Employee u WHERE u.department = ?1")

而不是这个：

@Query("SELECT u FROM Employee u WHERE u.department = ?")

或者您可以将其更改为：

@Query("SELECT u FROM Employee u WHERE u.department = :department ")

基于你的函数的参数名称

最后，我设法修复了这些错误，仅通过更改 Spring Boot 版本，我有3.0.2 ，然后我更改为3.0.1并且它有效！
