I am not sure if this is what want, but I do something like this with my
classes
my audited entity
@Auditable(values = { AuditableOperation.CREATE, AuditableOperation.UPDATE
})
public class MyClass implements Serializable {
(...)
}
my persistence.xml
<property name="openjpa.Auditor"
value="my.DatabaseAuditor(sequence='false',synchDriver='oracle.jdbc.OracleDriver',synchDriverUser='myuser',synchDriverPassword='mypass',synchDriverJdbc='jdbc:oracle:thin:@localhost
:1521:XE')"/>
my Auditor
public class DatabaseAuditor implements Auditor {
private AuditLogger defaultAuditor = new AuditLogger();
private String synchDriver;
private String synchDriverUser;
private String synchDriverPassword;
private String synchDriverJdbc;
private String sequence;
@Override
public void audit(Broker broker, Collection<Audited> newObjects,
Collection<Audited> updates, Collection<Audited> deletes) {
(...)
if (updates.size() > 0) {
for (Audited a : updates) {
this.addChangeLogForUpdate(a);
}
}
}
and addChangeLogForUpdate can access both previous and new values just
using
for (String field : audited.getUpdatedFields()) {
if (Arrays.asList(DatabaseAuditor.FIELDS).contains(field)) {
newdata.put(field, audited.getManangedFieldValue(field));
olddata.put(field, audited.getOriginalFieldValue(field));
//use driver info to save this using plain JDBC
I hope it helps
