What is the correct way to add my custom implementation of UserDetailsService (which uses Spring Data JPA) to Spring Boot app?
public class DatabaseUserDetailsService implements UserDetailsService {
@Inject
private UserAccountService userAccountService;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userAccountService.getUserByEmail(username);
return new MyUserDetails(user);
}
}
public interface UserRepository extends JpaRepository<User, Long>, JpaSpecificationExecutor<User> {
public User findByEmail(String email);
}
@Service
public class UserAccountService {
@Inject
protected UserRepository userRepository;
public User getUserByEmail(String email) {
return userRepository.findByEmail(email);
}
}
@Configuration
@ComponentScan
@EnableAutoConfiguration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.sample")
@EntityScan(basePackages = { "com.sample" })
@EnableJpaAuditing(auditorAwareRef = "auditorProvider")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
...
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
protected static class ApplicationSecurity extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/").hasRole("USER")
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
}
}
@Order(Ordered.HIGHEST_PRECEDENCE + 10)
protected static class AuthenticationSecurity extends GlobalAuthenticationConfigurerAdapter {
@Inject
private UserAccountService userAccountService;
@Override
public void init(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService());
}
@Bean
public UserDetailsService userDetailsService() {
return new DatabaseUserDetailsService();
}
}
}
@Entity
public class User extends AbstractPersistable<Long> {
@ManyToMany
private List<Role> roles = new ArrayList<Role>();
// getter, setter
}
@Entity
public class Role extends AbstractPersistable<Long> {
@Column(nullable = false)
private String authority;
// getter, setter
}
I cannot start app beacouse I get (full exception here http://pastebin.com/gM804mvQ)
Caused by: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.sample.model.User.roles[com.sample.model.Role]
at org.hibernate.cfg.annotations.CollectionBinder.bindManyToManySecondPass(CollectionBinder.java:1134)
When I configure my ApplicationSecurity with auth.jdbcAuthentication().dataSource(dataSource).usersByUsernameQuery("...).authoritiesByUsernameQuery("...") everything is working including JPA and Spring Data repositories.
回答1:
Your app seems to work for me (once I added @Configuration to the AuthenticationSecurity). Here's another working sample of a simple app with JPA UserDetailsService in case it helps: https://github.com/scratches/jpa-method-security-sample

You can also follow this blog to implement custom user details service.
This example shows how you can send bean to userdetails service for injection.
- Autowire the Repository in the WebSecurityConfigurer
- Send this bean as a parameter to the user details service by a parameterized constructor.
- assign this a private member and use to load users from database.
