Mongodb – Failed to execute CommandLineRunner

I have a spring boot application that has been up running for months now. Everything was fine until I added this line in the UserRepository that extends MongoRepository: List<User> findAllByUserName(List<String> usernames);

Now I get the following error:

I’ve tried fixing it by using the @Query annotation :

    @Query("{ 'userName' : ?0 }")
    List<User> findAllByUserName(List<String> usernames);

I also tried adding spring.batch.job.enabled=false to application.properties. None of them worked

    I cant say if the @Query Annotation does also work with a List<String> but at least are you usign the wrong Query the $in Operator is missing. Try it on this way and if it works also try it with a List<String>

    @Query("{ 'userName' : { $in : ?0 } }")
List<User> findAllByUserName(String[] usernames);

    If your argument is a collection, you may need to use In suffix, so that the query generated uses $in: [].

    List<User> findAllByUserNameIn(List<String> usernames);
