使用Spring Boot 1.3.1,我遇到了@AuthenticationPrincipal
。
这是我的控制者:
@RestController
@RequestMapping("/api/user")
public class UserController {
@RequestMapping("/")
public UserDto user(@AuthenticationPrincipal(errorOnInvalidType = true) User user) {
return UserDto.fromUser(user);
}
}
这是我的自定义用户类:
@Entity()
@Table(name = "app_user")
public class User extends AbstractEntity<UserId> implements Serializable {
// ------------------------------ FIELDS ------------------------------
@NotNull
@Column(unique = true)
@Pattern(regexp = "[a-zA-Z_\\-\\.0-9]+")
@Size(min = 1, max = 20)
private String username;
private String password;
@Column(unique = true)
@Email
private String emailAddress;
@Enumerated(EnumType.STRING)
@NotNull
private UserRole role;
}
我还创建了一个类来确认Spring Security的UserDetails
接口:
public class CustomUserDetails extends User implements UserDetails {
public CustomUserDetails(User user) {
super(user);
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return Sets.newHashSet(new SimpleGrantedAuthority("ROLE_" + getRole().name()));
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}
然后在我的UserDetailsService
:
@Override
public CustomUserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
com.company.app.domain.account.User user = userRepository.findByUsername(username);
if (user != null) {
return new CustomUserDetails(user);
} else {
throw new UsernameNotFoundException(format("User %s does not exist!", username));
}
}
我有一个完美的集成测试。但是,运行应用程序本身(来自IntelliJ IDEA)不起作用。我得到一个例外:
"CustomUserDetails{id=UserId{id=401868de-99ff-4bae-bcb6-225e3062ed33}} is not assignable to class com.company.app.domain.account.User"
但事实并非如此,因为CustomUserDetails
是我的自定义User
类的子类。
使用调试器检查,我发现AuthenticationPrincipalArgumentResolver
中的此代码失败了:
if (principal != null
&& !parameter.getParameterType().isAssignableFrom(principal.getClass())) {
parameter.getParameterType()
的类加载器是RestartClassloader
的实例,而principal.getClass()
的类加载器是Launcher$AppClassLoader
的实例。
这是Spring Boot或Spring Security中的错误还是我做错了什么?
更新:
我可以确认禁用Spring Boot的devtools使其工作:
public static void main(String[] args) {
System.setProperty("spring.devtools.restart.enabled", "false");
SpringApplication.run(MyApplication.class, args);
}
答案 0 :(得分:1)
为了帮助遇到同样问题的其他人,这是Spring Boot DevTools和Spring Security OAuth的限制。它在此问题中被跟踪:https://github.com/spring-projects/spring-boot/issues/5071
