While using version 2.1.3

I have a POJO that has an int property with the proper setters and getters:

int riskScore

The field in the DB is nullable so I mapped it as such:

<property name="riskScore" column="risk_score" not-null="false" update="false" type="java.lang.Integer"/>

I tried to get more information by making this setting in hibernate.cfg.xml:

<property name="hibernate.cglib.use_reflection_optimizer">false</property>

When I do all of this I get an exception:

net.sf.hibernate.PropertyAccessException: exception setting property value with
CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter
of com.tracfone.max.Alarm.setRiskScore
at net.sf.hibernate.persister.AbstractEntityPersister.setPropertyValues(
AbstractEntityPersister.java:212)
at net.sf.hibernate.impl.SessionImpl.initializeEntity(SessionImpl.java:2
199)
at net.sf.hibernate.loader.Loader.doQuery(Loader.java:240)


etc....

If I change the property type to Integer in the POJO, everything works out correctly. But I don't want to adjust all of the current code to change the type of the property from int to Integer.

I thought I could map a nullable primative by specifying it's coresponding object type in the mapping XML. Am I wrong? Where do I find a way to solve this issue?

Use a custom UserType to convert the null values to some other value. primitive types can't be null.

change your getter and setter for that property to String, and
<property
name="batchId"
type="java.lang.String"
column="batch_id"
length="4"
/>
