JHipster 7.1.0: Failed to use jdl-import, throws Error looking for otherEntity User at

Im using java Openjdk 11.0.11, JHipster 7.1.0 and node v14.17.3 Im creating a simple microservice (one backend and one gateway) but JHipster fails to create using the jdl command (jdl-import), it throws

It does create the folders blogBackend, blogGateWat and docker-compose .... but the folder blogBackend is empty.

If I move to blogGateWay and run: mvn clean install

I get an exception also;

I will post the instantiated error as a separate question.

Any idea how to solve this?

Here is the jdl-file (blog.jdl) that I use:

application {
  config {
    applicationType gateway,
    baseName blogGateWay,
    packageName com.carestra.learn.jhipster.gateway,
    authenticationType jwt,
    serviceDiscoveryType eureka,
    buildTool maven,
    reactive true, // default true
    skipClient false,
    skipServer false,
    skipUserManagement false,
    databaseType sql,
    prodDatabaseType postgresql,
    devDatabaseType h2Disk,
    cacheProvider ehcache,
    testFrameworks [cypress]
  }

  entities *
}

application {
  config {
    applicationType microservice,
    baseName blogBackend,
    packageName com.carestra.learn.jhipster.backend,
    authenticationType jwt,
    serviceDiscoveryType eureka,
    buildTool maven,
    reactive true,
    skipClient true,
    skipUserManagement true,
    clientFramework react,
    databaseType sql,
    prodDatabaseType postgresql,
    devDatabaseType h2Disk,
    cacheProvider hazelcast,
    enableHibernateCache true,
    testFrameworks [cypress]
  }

  entities *
}

entity Blog {
  name String required minlength(3)
  handle String required minlength(2)
}

entity Post {
  title String required
  content TextBlob required
  date Instant required
}

entity Tag {
  name String required minlength(2)
}

entity Product {
  title String required
  price BigDecimal required min(0)
  image ImageBlob
}

relationship ManyToOne {
  Blog{user(login)} to User
  Post{blog(name)} to Blog
}

relationship ManyToMany {
  Post{tag(name)} to Tag{post}
}


microservice * with blogBackend

deployment {
  deploymentType docker-compose
  appsFolders [blogGateWay, blogBackend]
  dockerRepositoryName "carestra"
  serviceDiscoveryType eureka
}

Steps to reproduce: 1 - Create folder blog 2 - Move to folder blog 3 - Run: jhipster jdl blog.jdl 4 - Mover to blogGateWay 5 - Run: mvn clean install

Running: jhpster info om folder blog gives me;

Almost the same error took me an hour to find the solution. In my case I was writing relationship entity name incorrectly, so writing correct relationship entity name did the trick. I was writing:

ChatToSearch

but my entity name was:

ChatsToSearch

So, I have corrected it and it worked!

The error occurs because you're using JWT authentication type and not OAuth2.

For OAuth2, there is a mechanism in the microservice to extract user data from token and save it to the service's database.

Unfortunately, I could not find any doc about this so I read the code at https://github.com/jhipster/generator-jhipster/blob/main/utils/entity.js where the test to determine whether to activate this user snapshot is:

  entityWithConfig.saveUserSnapshot =
    entityWithConfig.applicationType === MICROSERVICE &&
    entityWithConfig.authenticationType === OAUTH2 &&
    hasBuiltInUserField &&
    entityWithConfig.dto === NO_MAPPER;

You can see that there is also a condition about not using a DTO.

This mechanism has some restrictions though because the user's data is updated only when service API gets called, you can imagine cases where a user has been updated in gateway and a background job is running in service that will use a stale version of the user.

For JWT, this has not been implemented because the token does not contain enough data about user, it contains only the login and roles.

So with JWT, can you store in Blog only the ID (or login) of a User and not define a relationship with User entity because it exists only in gateway database.
