Mongo Repository find by condition is not working

Question

I have a MongoRepository query method which needs to fetch data based on conditions.

I have the following record in database.

{
'name' : 'test',
'show' : false,
'free' : true
}

And the following query, But the query doesn't return this record.

repositiry.findByNameNotNullAndShowIsTrueOrFreeIsTrue()

as per the condition, Name is not null and Free is True . But Why am I not getting the record.

Answer 1

I reproduced your scenario. It's working here. The query logged was correct.

{
    "$or": [
        {
            "name": {
                "$ne": null
            },
            "show": true
        },
        {
            "free": true
        }
    ]
}

To enable the mongodb query logs you must DEBUG MongoTemplate.

logging.level.org.springframework.data.mongodb.core.MongoTemplate = DEBUG

Entity

@Document
@Data
@Builder
class Entity {
    private String id;
    private String name;
    private boolean show;
    private boolean free;
}

Repository

interface EntityRepository extends MongoRepository<Entity,String> {

    List<Entity> findByNameIsNotNullAndShowIsTrueOrFreeIsTrue();
}

Test

@Test
    public void testQuery() {
        repository.deleteAll();

        Entity entity = Entity.builder()
                .free(true)
                .show(false)
                .name("test")
                .build();
        repository.save(entity);

        List<Entity> entities = repository.findByNameIsNotNullAndShowIsTrueOrFreeIsTrue();

        Assert.assertEquals(1, entities.size());
    }
