How to fix org.hibernate.PropertyAccessException: IllegalArgumentException exception in spring boot application

Question

I am getting the below exception when i run the spring boot application. But the same code works fine when we execute as a plain java.

Exception:

at org.springframework.boot.devtools.restart.RestartLauncher.run(RestartLauncher.java:49) Caused by: org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of com.sample.model.TRSN_LOOKUP.emClntId at org.hibernate.property.access.spi.GetterMethodImpl.get(GetterMethodImpl.java:64) at org.hibernate.tuple.entity.AbstractEntityTuplizer.getIdentifier(AbstractEntityTuplizer.java:230) at org.hibernate.persister.entity.AbstractEntityPersister.getIdentifier(AbstractEntityPersister.java:4725)

This is for spring-boot standalone application running in windows

 Session session = getSession();
if (!session.getTransaction().isActive() )
    session.beginTransaction();

    TRSN_LOOKUP trsnlookup = new TRSN_LOOKUP();             

        trsnlookup.setPrsnid(PrsnId);
        trsnlookup.setEmClntId(clientId);           

    session.save(trsnlookup);
    session.getTransaction().commit();

Continuation from my above comments:

Just try with naming-strategy property which will help you to use a similar name.

For example,: Spring will change entity name from TRSN_LOOKUP to tRSN_LOOKUP . So, please try adding one more property in hibernate.

There are two types of strategy, you can use 2nd one:

1. org.hibernate.cfg.ImprovedNamingStrategy

2. org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

which help you keep the same name in all DB fields.
