org.hibernate.hql.internal.ast.QuerySyntaxException: InspectionRequestEntity is not mapped

Question

I am using Hibernate 5.4.9 with Spring 5.2.2 and PostGreSql. I am Trying to retrieve a list of items from database and populate the Datatable. I am Using annotations so there is no hibernate cfg.xml or hbm.xml file in the project. My Entity class looks like

My Repository class looks like

@Repository("inspectionRequestRepo")
@Transactional
public class InspectionRequestRepository {

private EntityManagerFactory entityManagerFactory;
public int getCountInspectionRequestBySrchParam(searchInspectionRequestVO searchVO) {
    EntityManager entityManager = entityManagerFactory.createEntityManager();

    StringBuilder builder = new StringBuilder();

    if (searchVO.getSearchMap() != null) {
        Iterator<String> itr = searchVO.getSearchMap().keySet().iterator();

        while (itr != null && itr.hasNext()) {
            String key = itr.next();
            if(searchVO.getSearchMap().get(key) instanceof Date)
            {
                builder.append(" AND (u.");
                builder.append(key);

                if(searchVO.getSearchMap().get(key).equals("%"))

                    builder.append(key);
                    builder.append(" is null)");
                }else {
                    builder.append(")");
                }
            } else if(searchVO.getSearchMap().get(key) instanceof Integer)

I don't Understand What Iam missing?

Answer 1

Even if you are using annotations, you still need to register your entity classes somewhere.

There are different ways to do this:

1. in the hibernate.cfg.xml

    <mapping class="co.in.grse.inspectionrequest.entities.InspectionRequestEntity" />

2. programmatically, using Configuration:

    import org.hibernate.cfg.Configuration; Configuration configuration = constructConfiguration(); configuration.addAnnotatedClass( InspectionRequestEntity.class )

3. with the persistence.xml if you are using JPA, unless you specify

   <exclude-unlisted-classes>false</exclude-unlisted-classes>

There might be others that I'm missing right now.
