spring mvc - Aspect Auditing Field changes -
i'm trying capture filed changes using aspect auditing posibilities , custom anotations, can't old value. here code:
public aspect fieldauditaspect { @autowired activityservice activityservice; @autowired userservice userservice; pointcut auditfield(object t, object value): set(@ge.shemo.model.client.aopaudit * *) && args(value) && target(t); before (object target, object newvalue): auditfield(target, newvalue) { fieldsignature sig = (fieldsignature) thisjoinpoint.getsignature(); field field = sig.getfield(); field.setaccessible(true); object oldvalue; try { oldvalue = field.get(target); } catch (illegalaccessexception e) { throw new runtimeexception("failed create audit action", e); } system.out.println("changed " + oldvalue + " " + newvalue); } } this custom annotation use mapping desired filed capture changes:
@retention(runtime) @target(value = { type, field}) public @interface aopaudit { } here pom.xml

@entity @entitylisteners(auditingentitylistener.class) public class client { @aopaudit private string firstname; @aopaudit private string lastname; @enumerated(enumtype.string) private gender gender; ..... this function update entity:
public client saveclient(clientdto clientdto) { dozerbeanmapper mapper = new dozerbeanmapper(); client client = getclient(clientdto.getid); //getting client db client = mapper.map(clientdto, client.class); //casting dto entity using dozerbeanmapper saveclient(client); everything works fine except don't old value - old value null. need old value save don't understand why i'm not getting old value.
can tell me i'm doing wrong?
i'm using spring mvc + jpa
let me try explain how supposed work. fieldauditaspect triggered before set operations fields having @aopaudit annotation, , target(t) in pointcut definition means object instance affected aspect.
in case following:
client = mapper.map(clientdto, client.class); this means mapper create new instance of client, has empty field values, , populate corresponding clientdto field values. so null old values taken from.
to work expect should same fetched client object, follows:
client = mapper.map(clientdto, client); client object used here instead of client.class
if should see old field values, present in fetched client object, in combination new one, present in clientdto.
