JPA Cannot resolve column/IntelliJ
You have to associate your data source (create a data source in database view first - aka your real JDBC database connection) with a persistence unit or session factory (hibernate.cfg.xml).
Follow below steps and the warnings will disappear:
- Open the Persistence tool window (View | Tool Windows | Persistence).
- Right-click the necessary module, persistence unit or session factory, and select Assign Data Sources in the context menu.
- In the Assign Data Sources dialog that opens, click the Data Source field and select the necessary data source. (To remove the association with the data source, select .)
See here: Associating data sources with session factories and persistence units
For those who just want to disable this check, go to
Intellij IDEA -> Preferences -> Search "Unresolved database references in annotations" and uncheck it.
(macOS Mojave and Intellij Ultimate 2019.3)
This will disable the inspection and remove all the "Cannot resolve column…" errors on the @Column annotations. Intellij will stop checking if the String column names exist in the database tables. Do it at your own risk.
