I am using envers to audit my ParameterToValue entity. Its properties “containerId”, “containerType”, “parameterId” which do appear as columns in a mapped DB table “values_for_params” (a regular Hibernate table), are missing at the envers generated “values_for_params_AUD” DB table. I need the ability to get historic “value” for given (containerId, containerType, parameterId).
The ParameterToValue class:
@Audited
public class ParameterToValue extends BasicValueHolder {
private Long containerId;
private ContainerType containerType;
private Long parameterId;
public ParameterToValue(ContainerID containerId, Long parameterId, Value value) {
super(value);
this.containerId = containerId.getContainerId();
this.parameterId = parameterId;
containerType = containerId.getContainerType();
}
ParameterToValue() {
}
public Long getParameterId() {
return parameterId;
}
public void setParameterId(Long parameterId) {
this.parameterId = parameterId;
}
public Value getValue() {
return value;
}
public void setValue(Value value) {
this.value = value;
}
public Long getContainerId() {
return containerId;
}
public void setContainerId(Long containerId) {
this.containerId = containerId;
}
public ContainerType getContainerType() {
return containerType;
}
public void setContainerType(ContainerType containerType) {
this.containerType = containerType;
}
}
The Hibernate mapping definition:
<class name="platform.server.dataservices.model.ParameterToValue" table="values_for_params">
<cache usage="read-write" include="all" />
<id name="id" column="ID">
<generator class="native"/>

<!-- 12 = string, 5 = smallint, 4 = integer, default 4 -->
</type>
</property>
</properties>

Fixed. In case anybody needs the answer:
The problem was that envers ignored whatever was written inside the properties tag. When I removed the tag this way:
Became:
This way, all of the properties became audited, but I still needed the triplet (containerId, parameterId, containerType) to be unique. The final solution was this:
