Suppose I have such entity:
public class Foo {
private long id;
private List<Bar> list = new ArrayList<>();
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public List<Bar> getList() {
return list;
}
public void setList(List<Bar> list) {
this.list = list;
}
/** helper method*/
public boolean isEmpty(){
return list.isEmpty();
}
}
And corresponding entity mapping:
<?xml version="1.0" encoding="UTF-8" ?>
<entity-mappings xmlns="http://xmlns.jcp.org/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence/orm"
version="2.1">
<entity class="Foo">
<table name="foo"/>
<attributes>
<id name="id"/>
<one-to-many name="list">
<!-- ... -->
</one-to-many>
<transient name="isEmpty"/>
</attributes>
</entity>
</entity-mappings>
And this exception I got:org.hibernate.PropertyNotFoundException: Could not locate setter method for property [Foo#empty]
I found a similar post - HIbernate Mapping Exception: PropertyNotFoundException: Could not find a setter and there Trainsient annotation on such method helped.
