Criteria throwing a lot of PropertyReferenceException

[felipe-issa-zebra]

Our app uses Spring boot 3.3.6 and have the following scenario:

Model:

@Document(collection = "STORAGE_CLASS")
public class StorageClass {

    @Field("STATUS")
    private String status;

    @Field("FIELD_NUMBER")
    private long numberField;

    ... // getters, setters, tostring
}

We need to query this collection on database every 10 seconds, so we wrote a dao for it:

public interface StorageClassDao {
    List<StorageClass> getStorage();
}
@Repository
public class StorageClassDaoImpl implements StorageClassDao {
    private MongoTemplate mongoTemplate;
    public StorageClassDaoImpl(MongoTemplate mongoTemplate) {
        this.mongoTemplate = mongoTemplate;
    }

    @Override
    public List<StorageClass> getStorage() {
        Criteria criteria = Criteria.where("STATUS").is("E")
            .and("FIELD_NUMBER").is(1);
        Query query = new Query(criteria);
        return this.mongoTemplate.find(query, StorageClass.class);
    }
}

This works, I receive data from getStorage which matches the query I passed. However I see a lot of PropertyReferenceException are being thrown (If I add a breakpoint to this exception), with the messages as follows:

• No property 'STATUS' found for type 'StorageClass'
• No property 'STATU' found for type 'StorageClass'
• No property 'STAT' found for type 'StorageClass'
• No property 'STA' found for type 'StorageClass'
• No property 'ST' found for type 'StorageClass'
• No property 's' found for type 'StorageClass'
• No property 'FIELD' found for type 'StorageClass'
• No property 'FIEL' found for type 'StorageClass'
• No property 'FIE' found for type 'StorageClass'
• No property 'FI' found for type 'StorageClass'
• No property 'f' found for type 'StorageClass'
• No property 'FIELD_NUMBER' found for type 'StorageClass'
• No property 'FIELD_NUMBE' found for type 'StorageClass'
• No property 'FIELD_NUMB' found for type 'StorageClass
• No property 'FIELD_NUM' found for type 'StorageClass'
• No property 'FIELD_NU' found for type 'StorageClass'
• No property 'FIELD_N' found for type 'StorageClass''
• No property 'FIELD_' found for type 'StorageClass'

The exceptions are throwed manly from two places:

• Exception 'org.springframework.data.mapping.PropertyReferenceException' occurred in thread 'scheduling-1' at org.springframework.data.mapping.PropertyPath.create(PropertyPath.java:490)
• Exception 'org.springframework.data.mapping.PropertyReferenceException' occurred in thread 'scheduling-1' at org.springframework.data.mapping.PropertyPath.(PropertyPath.java:94)

For every service call, more than 100 of this exceptions are being throwed. On our actual app, more than 100k exception are being throwed / GC, which is consuming a lot of unecessary resources.

What am I doing wrong here?

Thanks for getting in touch, but it feels like this is a question that would be better suited to Stack Overflow. We prefer to use GitHub issues only for bugs and enhancements. Feel free to update this issue with a link to the re-posted question (so that other people can find it) or add some more details if you feel this is a genuine bug.

Data MongoDB uses domain type information to map fields to their field names considering @Field annotations. Please use property names from your java type. something like Criteria.where("status").is("E").and("numberField").is(1);

Hey @christophstrobl , I've done it one month ago, and had no answer there, thats why I oepened it here as a bug (there seems to be no way around this many exceptions).

just make sure to use the property names from the domain model. We've an open ticket (spring-projects/spring-data-commons#3220) that aims at improving the path resolution.
