Hibernate problem

[Albin Joseph]

Hi

I am getting an exception in my Hibernate exception. Below is the stack trace of my exception.

he following exception was logged org.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.javacertificate.data.table.Exam.setField1
at org.hibernate.tuple.PojoEntityTuplizer.setPropertyValuesWithOptimizer(PojoEntityTuplizer.java:215)
at org.hibernate.tuple.PojoEntityTuplizer.setPropertyValues(PojoEntityTuplizer.java:185)
at org.hibernate.persister.entity.AbstractEntityPersister.setPropertyValues(AbstractEntityPersister.java:3232)
at org.hibernate.engine.TwoPhaseLoad.initializeEntity(TwoPhaseLoad.java:129)
................................


This is my database details for this field.

+---------------+--------------+------+
| Field | Type | Null |
+---------------+--------------+------+
| FIELD1 | bigint(20) | YES |
+---------------+--------------+------+

my mapping is

<property name="field1" type="long">
<column name="FIELD1" />
</property>

and following is my java class.

private long field1;

public long getField1() {
return field1;
}

public void setField1(long field1) {
this.field1 = field1;
}

How can I resolve this issue ?

Could the problem be that the database column allows NULL, but you are using a java primitive long value.

try using the java.lang.Long for the property in your class.

i.e.

private Long field1;

public void setField1(Long value) { this.field1 = value; }
public Long getField1() { return this.field1; }

Also noticed this,

Hibernate does some internal optimization by default the error message is telling us that if we turn this optimization off, we may be able to get a more specific message or more hints to what the problem is.

in the hibernate.properties you can set
hibernate.cglib.use_reflection_optimizer=false

(at least temporarily for debugging)
Then try to do the things you did before and see if the error message is different.

Just to bring the post to a logical conclusion:

I encountered the same problem today and found out that Travis' suggestion of converting the primitive to wrapper (Long) class did the trick.

As for the second suggestion, it did print a whole lot more when the value of hibernate.bytecode.use_reflection_optimizer is changed but the error messages were not particularly helpful.

i had this same problem but with a boolean field. i changed the boolean getter/setters to be Boolean (capital B ). I also made a check in my getter to firstly check if the field was null and if it was return false.

-another option as already stated is to update all the null values to be false in the table.
