java - 无法 Autowiring 自定义用户详细信息

标签 java spring spring-mvc spring-security spring-boot

Spring Boot 应用程序有一个自定义的 UserDetails。当应用程序所做的只是使用 User 类对数据库中的现有用户进行身份验证时，一切都会正常工作。然而，当我尝试进行更改以便人们可以通过应用程序 GUI 创建新的用户帐户时，问题出现了。具体来说，将自定义 UserDetailsS​​ervice 更改为 UserDetailsManager 需要更改 User 类以显式实现 UserDetails，其中现在，当我从应用程序的根目录在终端中输入 java -jar target/modular-0.0.1-SNAPSHOT.jar 时，turn 导致 Spring 无法编译 jar。

核心错误信息是:

    java.lang.IllegalArgumentException: 
    Not an managed type: interface org.springframework.security.core.userdetails.UserDetails

需要对下面的代码进行哪些具体更改才能使 Spring 能够使用自定义 UserDetails 和 UserDetailsManager 编译应用程序？

以下是应用程序中核心类的代码，其中包括 Spring Security 配置:

@SpringBootApplication
@Controller
@EnableJpaRepositories(basePackages = "demo", considerNestedRepositories = true)
public class UiApplication extends WebMvcConfigurerAdapter {

    @Autowired
    private WebLeadRepository myrepo;   

    @Autowired
    private Users users;//duplicate from AuthenticationSecurity internal class below. Remove one?

    // Match everything without a suffix (so not a static resource)
    @RequestMapping(value = "/{[path:[^\\.]*}")
    public String redirect() {
        // Forward to home page so that route is preserved.
        return "forward:/";
    }

    @RequestMapping("/user")
    @ResponseBody
    public Principal user(Principal user) {
        return user;
    }

//lots of other @RequestMapping @ResponseBody url handling methods

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

    @Order(Ordered.HIGHEST_PRECEDENCE)
    @Configuration
    protected static class AuthenticationSecurity extends GlobalAuthenticationConfigurerAdapter {

        @Autowired
        private Users users;

        @Override
        public void init(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(users);
        }
    }

    @SuppressWarnings("deprecation")
    @Configuration
    @Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
    @EnableWebMvcSecurity
    @EnableGlobalMethodSecurity(prePostEnabled = true)
    protected static class SecurityConfiguration extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.httpBasic().and().authorizeRequests()
                .antMatchers("/sign-up").permitAll()
                .antMatchers("/index.html", "/", "/login", "/something*") 
                .permitAll().anyRequest().authenticated().and().csrf()
                .csrfTokenRepository(csrfTokenRepository()).and()
                .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
        }

        private Filter csrfHeaderFilter() {
            return new OncePerRequestFilter() {
                @Override
                protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
                    throws ServletException, IOException {
                        CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class.getName());
                        if (csrf != null) {
                            Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
                            String token = csrf.getToken();
                            if (cookie == null || token != null && !token.equals(cookie.getValue())) {
                                cookie = new Cookie("XSRF-TOKEN", token);
                                cookie.setPath("/");
                                response.addCookie(cookie);
                        }
                    }
                    filterChain.doFilter(request, response);
                }
            };
        }

        private CsrfTokenRepository csrfTokenRepository() {
            HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
            repository.setHeaderName("X-XSRF-TOKEN");
            return repository;
        }
    }

    @Repository//This repository is what Spring cannot seem to create in the stack trace
    interface UserRepository extends CrudRepository<UserDetails, Long> {
        User findByName(String name);
    }

}

Users.java 是:

@Service
class Users implements UserDetailsManager {

    private UserRepository repo;

    @Autowired
    public Users(UserRepository repo) {this.repo = repo;}

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = repo.findByName(username);
        if (user == null) {throw new UsernameNotFoundException("Username was not found. ");}
        List<GrantedAuthority> auth = AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_USER");
        if (username.equals("admin")) {auth = AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_ADMIN");}
        String password = user.getPassword();
        return new org.springframework.security.core.userdetails.User(username, password, auth);
    }

    @Override
    public void createUser(UserDetails user) {// TODO Auto-generated method stub
        repo.save(user);
    }

    @Override
    public void updateUser(UserDetails user) {// TODO Auto-generated method stub
        repo.save(user);
    }

    @Override
    public void deleteUser(String username) {// TODO Auto-generated method stub
        User deluser = (User)this.loadUserByUsername(username);
        repo.delete(deluser);
    }

    @Override
    public void changePassword(String oldPassword, String newPassword) {
        // TODO Auto-generated method stub
    }

    @Override
    public boolean userExists(String username) {
        // TODO Auto-generated method stub
        return false;
    }

}

而User.java是:

@Entity
class User implements UserDetails{

    @GeneratedValue
    @Id
    private Long iduser;
    private String name;//valid email address only
    private String password;
//lots of other properties that model all the things the User does in the app

    //getters and setters
    public String getName() {return name;}//valid email address
    public void setName(String name) {this.name = name;}//valid email address

    public String getPassword() {return password;}
    public void setPassword(String password) {this.password = password;}

    //LOTS OF OTHER GETTERS AND SETTERS OMITTED HERE, THAT MANAGE MANY CUSTOM PROPERTIES

    // Also, All the following are for implementing UserDetails
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {// TODO Auto-generated method stub
        return null;
    }
    @Override
    public String getUsername() {// TODO Auto-generated method stub
        return null;
    }
    @Override
    public boolean isAccountNonExpired() {// TODO Auto-generated method stub
        return false;
    }
    @Override
    public boolean isAccountNonLocked() {// TODO Auto-generated method stub
        return false;
    }
    @Override
    public boolean isCredentialsNonExpired() {// TODO Auto-generated method stub
        return false;
    }
    @Override
    public boolean isEnabled() {// TODO Auto-generated method stub
        return false;
    }
}

WebLeadRepository.java 是:

public interface WebLeadRepository extends JpaRepository<WebLead, Long> {

    List<WebLead> findByLastname(String lastName);
    List<WebLead> findBySessionid(String sid);
    WebLead findByIdlead(Long idl);
}

完整的堆栈跟踪对于本次发布而言太长，但是 I have uploaded the complete stack trace to a file sharing site, which you can view by clicking on this link 。另外，堆栈跟踪中的根本原因总结如下:

最佳答案

首先，您需要修复存储库的映射，您尝试保留的对象是 User 而不是 UserDetails。 Spring Data JPA 需要此信息，以便它可以扫描实体并创建必要的绑定(bind)。 

@Repository
interface UserRepository extends CrudRepository<User, Long> {
    User findByName(String name);
}

现在，您的自定义 UserDetailsManager 类 Users 中将遇到编译问题。因为所有方法都采用 UserDetails 对象，而不是您的 User 对象，而该对象是您的 UserRepository 所期望的。要解决此问题，只需将参数转换为 User，然后再将其传递给 UserRepository。 

@Override
public void createUser(UserDetails user) {// TODO Auto-generated method stub
    repo.save((User) user);
}

@Override
public void updateUser(UserDetails user) {// TODO Auto-generated method stub
    repo.save((User) user);
}
