Intellij IDE show error highlight in Entities

Question

I open a spring boot project in IntelliJ IDEA 2020.1.2 (Ultimate Edition) , and I hot many error highlight in entities, like:

• Cannot resolve table 'roles'
• Class 'RolesEntity' should have [public, protected] no-arg constructor
• Cannot resolve table 'user_roles'

But when I open my project in old version like IntelliJ IDEA 2019.3.3 (Community Edition) I don't see this problem.

IntelliJ IDEA 2020.1.2

IntelliJ IDEA 2019.3.3

Any reason for this problem or any fix please?

Answer 1

In IntelliJ idea go to

Setting-> Inspections->JPA->Unresolved database reference in annotations-> severity(which is just right)-> change from error to week warnning.

Answer 2

Try this one

---

File -> Project Structure

At left pane select "Facets". If there is no JPA listed, click "+" sign and add "JPA"

At bottom of same dialog, at "Default JPA Provider", select - "Hibernate", press "OK"

If you have error at @Table annotation, configure and choose data source

Table name for select now should be recognized as entity class name
