Failed to find access token for token

[maxim-filkov]

Hi, could you please help me to understand what is wrong with my setup. With InMemoryTokenStore everything works fine (I'm able to receive the tokens) but as I want the refresh tokens to be persisted, I switched to JdbcTokenStore (spring-security-jwt v1.0.5.RELEASE, spring-security-oauth2 v2.0.11.RELEASE). Now when I send access token request like follows:

curl -X POST -vu myapp12:TBe6G9W1t7Uv http://localhost:8080/oauth/token -H "Accept: application/json" -d "password=papidakos&username=cpapidas&grant_type=password&scope=read%20write&client_secret=TBe6G9W1t7Uv&client_id=myapp12"

I get:

{"error":"server_error","error_description":"java.io.NotSerializableException: Unmentionable.model.Role"}

[dsyer]

The error message looks pretty clear to me: "java.io.NotSerializableException: Unmentionable.model.Role". Presumably that is your custom user domain model? It needs to be serializable to go into the JDBC token store.

[maxim-filkov]

Hi Dave, thank you for help! But isn't this rather a consequence of the problem? I'm following this example. In that project the database is the same, the domain class Role is the same but InMemoryTokenStore is used instead of JdbcTokenStore. That project works just fine, Role is persisted with no problems and again I had nothing to do with it in my project. This Stackoverflow thread describes pretty the same problem.

Here is the domain class Role that is pretty straight forward. It is persisted according to this scheme.

JDBC token storage (MySQL database) (which contains not only oauth_* tables but also tables used to persist model entities, e.g. accounts, roles and groups - is this ok to reuse the same database for this?)

spring.datasource.url=jdbc:mysql://localhost:3306/unmentionable
spring.datasource.username=root
spring.datasource.password=awesomePassword123
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

[dsyer]

I'm not sure I follow. Your Role class is clearly not marked as Serializable, so it can't be serialized (that way at least). InMemoryTokenStore does not use Serializable, so that would explain why that worked.

[maxim-filkov]

Dave, sorry that was my lack of understanding. From what I know JPA-entities aren't required to be Serializable by the specification. Once I implemented Serializable the issue has been fixed, thank you.

If an entity instance is to be passed by value as a detached object (e.g., through a remote interface), the entity class must implement the Serializable interface.

Is this the case?

[dsyer]

It would seem so. It's dangerous though because you lose the connection to the database when you deserialize. If I were you I'd stick to spring POJOs or security base classes for user authentication.

[maxim-filkov]

Dave, for POJOs do you mean using of javax.persistence.Table, javax.persistence.Column annotations? Or why is the following class not enough POJO:

@Data // this is from Lombok to generate all Getters/Setters
@Entity
public class Group implements Serializable {

   @Id
   @GeneratedValue
   private Long id;

   @NotNull
   @Size(min = 8, max = 255, message = "Group name should be between 8 and 255 characters")
   private String name;

   @Size(min = 30, max = 512, message = "Group description should be between 20 and 512 characters")
   @Column(name = "description", length = 512)
   private String description;

   @Size(min = 3, max = 255, message = "Group country should be between 3 and 255 characters")
   private String country;

   @Size(min = 3, max = 255, message = "Group city should be between 3 and 255 characters")
   private String city;

}

Also could you please clarify for Spring security base classes for user authentication do you mean UserDetailsService, User, etc or something else?

[dsyer]

Sorry, I should have been more precise: what I meant was that using an @Entity as part of a security Principal can be dangerous. Sooner or later you will regret it, I predict, so it might be better to change the design.

[maxim-filkov]

So you're saying otherwise the Entity may "leak" into the web layer I guess. That's why it's better to add a data transfer object (DTO) between the web layer and service layer.

[dsyer]

It's worse than that really, it can leak into everything (e.g. across thread boundaries, and in particular across transaction boundaries, where the EntityManager will fail on you). Security is ubiquitous, so it's not really a layer.

[emreavsar]

I stepped over this issue since I came also to the great idea of storing the current user entity (not spring security user, i mean my own user) in the spring user details' principal.

the main idea was to be able to do something like this in my service:

	// somewhere in my service

	// CustomSpringSecurityUser extends the spring security user and adds a MyUser entity
	final CustomSpringSecurityUser customLoggedInUser = (CustomSpringSecurityUser) authentication.getPrincipal();

	// this is the user from the database
	final MyUser user = (MyUser) customLoggedInUser.getMyUser();

But since I'm using the JdbcTokenStore and this needs entities to implement Serializable i'm quite unsure to do this. I don't like this (because of later deserialization problems).

to quote you @dsyer :

Sorry, I should have been more precise: what I meant was that using an @entity as part of a security Principal can be dangerous. Sooner or later you will regret it, I predict, so it might be better to change the design.

This means doing always a lookup like this to get the user (instead of having the example above):

	// somewhere in my service

	// get the username to do a lookup
	final String username = ((User) authentication.getPrincipal()).getUsername();

	// do lookup via repo
	final MyUser user = userRepository.findByUsername(username);

this is safer, but brings also more lines of code into the game. correct?

[cheese10yun]

Did the issue resolved?

I found the same issue and solved it.

@OverRide
public UserDetails loadUserByUsername (String username) throws UsernameNotFoundException {
....
}
When returning the loadUserByUsername method, specify the user's type as the org.springframework.security.core.userdetails.User.class

Below is sample code.

@Override
    public UserDetails loadUserByUsername (String username) throws UsernameNotFoundException {
        final User user = userRepository.findByUsername (username);
        if (user == null) throw new UsernameNotFoundException (username);
        final UserPrincipal userPrincipal = new UserPrincipal (user);
        return new org.springframework.security.core.userdetails.User (
                userPrincipal.getUsername (),
                userPrincipal.getPassword (),
                userPrincipal.getAuthorities ()
        );
    }

If the problem is not solved, please give me a comment

I do not speak English well.

Look at the sample code as much as possible
