Exception in thread "main" java.lang.Error: Unresolved compilation problems: Configuration cannot be resolved to a type

I'm getting this error message. I'm learning Hibernate, So don't know much about it
I'm new to Hibernate and don't know much about it. When I try to run the code written below I'm getting an error message.
***** This is my main class *****

SessionFactory sf = con.buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();
session.save(alien);

Looks like local maven repo is not proper.
Delete .m2/repository/org/hibernate/*, then in eclipse: Maven/update Project. It will be re downloading the dependencies.
Also try cleaning the project in eclipse.

How to make unidirectional #oneToMany relationship for 2 tables using JPA and Hibernate

My project based on spring boot,Thymeleaf,mysql,html and Jquery.I tried to make a #oneToMany Relation with unidirectional in maintable,but it produces only error like

Please help me to solve this..Thanks in advance

The cause of the error is:
Unable to find column with logical name: propertysubpk in org.hibernate.mapping.Table(property_master)
The reason is that you have the referencedColumnName attribute wrong. It is supposed to be:
JPA 2.1 11.1.25: The name of the column referenced
by this foreign key column. When
used with entity relationship mappings
other than the cases described below, the
referenced column is in the table of the target
entity. When used with a unidirectional
OneToMany foreign key mapping, the referenced
column is in the table of the
source entity. When used inside a Join-
Table annotation, the referenced key column
is in the entity table of the owning
entity, or inverse entity if the join is part of
the inverse join definition. When used in a
collection table mapping, the referenced
column is in the table of the entity containing
the collection.
To explain: a #JoinColumn creates a column in the many side of the relation (the EntPropertySub here) with the given name that references the PK of the parent entity, unless referencedColumnName is specified. In the latter case the FK in the "many" table references the column given in referencedColumnName. In your case you want to reference the PK of EntPropertyMaster, so referencedColumnName is redundant. Simply use:
#OneToMany(cascade=CascadeType.ALL)
#JoinColumn(name="propertysubfkid")
private List<EntPropertySub> blockListPropSub = newArrayList<EntPropertySub>();

Try this: make sure how the foreign key in the table EntPopertySub called
#OneToMany(cascade=CascadeType.ALL)
#JoinColumn(name="propertyid")
private List<EntPropertySub> blockListPropSub = new ArrayList<EntPropertySub>();
It's not possible to create a physical column on the master table because you have a OneToMany relation. OneToMany means that Master has many Sub Table references.
Let's explain the Problem:
If you would have a column in the master table you need to would add a list of references in one cell.
For Example
------------------
| sub-fk |
|1, 2, 3, 4| <-- and this is against the database normalization
But this is not necessary:
Hibernate will automatically select all the referenced sub-columns for you (intern hibernate joins to the columns)
If you use the entitymanager to select the master data, the sub-data is included in the List blockListPropSub attribute

When you use the #JoinColumn on a #OneToMany relationship, the name attribute will point to the relating tables column, that is EntPropertySub entity and the referencedColumnName should be pointing to the column of the entity in which the #OneToMany annotation is present, that is EntPropertyMaster.
So basically you have it other way round and it should be in my opinion:
#OneToMany(cascade=CascadeType.ALL)
#JoinColumn(name="propertysubpk", referencedColumnName="propertysubfkid")
private List<EntPropertySub> blockListPropSub = newArrayList<EntPropertySub>();

The error clearly shows mapping missing in your schema relation.
You need to map EntPropertyMaster in EntPropertySub.
#OneToMany(cascade=CascadeType.ALL, mappedBy="entPropertyMaster")
private List<EntPropertySub> blockListPropSub = newArrayList<EntPropertySub>();
Provide EntPropertyMaster mapping in relation entity too.i.e.
#ManyToOne
#JoinColumn(name="entPropertyMasterId",referencedColumnName="id")
private EntPropertyMaster entPropertyMaster;
Relationships in JPA are always unidirectional, unless you associate
the parent with the child in both directions. Cascading REMOVE
operations from the parent to the child will require a relation from
the parent to the child (not just the opposite).

Finnaly i got a answer..
i made a changes in master entity "EntPropertyMaster"
"#OneToMany(cascade=CascadeType.ALL)"
"#JoinColumn(name="propertyidfk")"
private List<EntPropertySub> blockListPropSub = new ArrayList<EntPropertySub>();
It will create column in child table,but i wrote this code in parent Entity...
Please Note we need to give unique name for column creation,Then only it creates a column in child table.... not a primarykey column name
of child /parent table..

Spring boot, does not create beans #Controller, #Service

This is my project directory structure.
All controller and other classes and directories, which are beans, are under the "WebPortalApplication" class, and as Spring Boot doc states, we do not explicitly specify the package to scan for beans, whenever those packages locate unther the "main" class directory, right?
So when I run the "WebPortalApplication" file, it builds, but with such exceptions.

It looks like you're using JPA.
All JPA entities must be annotated with #Entity.
Caused by: java.lang.IllegalArgumentException: Not a managed type: class com.epam.webPortal.model.Role
means, Role class is missing #Entity annotation.

Have you enabled your repos?
#SpringBootApplication

I expect below definition on your RoleRepository; sharing this file will help to further analyze on what is missing.
public interface RoleRepository implements CrudRepository<Role, Long> {
...

You are not approaching this the right way. Your entities shouldn't be treated as Spring Beans.
#Autowired
private ArticoliOrdine articoliOrdine;
...
em.persist(articoliOrdine);
For long conversations you should either use:
Extended persistence context
detached objects saved in your Http Session
And detached entities shouldn't be passed to persist. You should merge them instead.
Persist is only meant for moving an entity state from TRANSIENT to PERSISTED. For DETACHED -> PERSISTED transitions you should always use EntityManager#merge() or Hibernate specific saveOrUpdate.

the value of the field moduleService is not Used

package com.maroclance.university.service;

i have the warning that moduleService is not used
when i execute my code i have this error

I'm really blocked

One of the classes ProfMat or Module has not mapped with Hibernate. The mapping should be defined via configuration. If you are using annotation configuration then put a #Table annotation on the associated classes and make sure that classes are scanned for annotations.
