要在Spring Security中自定義用戶詳細信息服務,可以按照以下步驟進行:
@Component
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userRepository.findByUsername(username);
if (user == null) {
throw new UsernameNotFoundException("User not found");
}
return new CustomUserDetails(user);
}
}
public class CustomUserDetails extends User {
private User user;
public CustomUserDetails(User user) {
super(user.getUsername(), user.getPassword(), user.getAuthorities());
this.user = user;
}
public User getUser() {
return user;
}
}
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomUserDetailsService customUserDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(customUserDetailsService);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/admin/**").hasRole("ADMIN")
.antMatchers("/user/**").hasRole("USER")
.anyRequest().authenticated()
.and()
.formLogin()
.and()
.httpBasic();
}
}
通過以上步驟,就可以在Spring Security中自定義用戶詳細信息服務。在自定義的UserDetailsService中,可以根據具體的業務邏輯加載用戶信息,并將其封裝成自定義的UserDetails類,供Spring Security進行身份驗證和授權。
