CXF REST: How to retrieve the Pojo object from the message in the interceptor before getting the group

@Path("/mypath")
public class MyResource {

 @GET
 public MyObject getObject() {
 MyObject o = new MyObject();
 ...
 return o;
 }
}

public class MyInterceptor extends AbstractPhaseInterceptor {

 public VersionOutInterceptor() {
 super(Phase.POST_LOGICAL);
 }

 public final void handleMessage(Message message) {
 // 1. STUCK - get object from the message
 // 2. par se annotations and manipulate the object
 // 3. put the object back on the message for serialization
 }
}

@Override
 public void handleMessage(Message message) throws Fault {
 MessageContentsList objs = MessageContentsList.getContentsList(message);
 if (objs != null && objs.size() == 1) {
 Object responseObj = objs.get(0);
 DomainPOJO do= (DomainPOJO)responseObj;
 _logger. info(do.toString());
 }
}

We have implemented a REST API in CXF. My goal is to be able to Define custom annotations on the POJO and process them in the CXF interceptor before they get marshalled. I believe that in addition to retrieving the actual objects in the interceptor, I also need all the information to be able to do this. My code looks like Like this:

>Resource class

@Path("/mypath")
public class MyResource {
 
 @GET
 public MyObject getObject() {
 MyObject o = new MyObject();
 ...
 return o;
 }
}

> MyObject

 public class MyObject {

 private String x;

 @MyAnnotation
 public String getX() {
 return x;
 }

 public String setX(x) {
 this.x = x;
 }
}

>Interceptor

public class MyInterceptor extends AbstractPhaseInterceptor {

 public VersionOutInterceptor() {
 super(Phase.POST_LOGICAL);
 }
< br /> public final void handleMessage(Message message) {
 // 1. STUCK - get object from the message
 // 2. parse annotations and manipulate the object
 // 3. put the object back on the message for serialization
 }
}

How to get the object from the message, manipulate it according to the comment, and put it back in the message?

I have similar requirements, this is what I can do

For In Interceptor, I used the PRE_INVOKE stage And Out Interceptor PRE_LOGICAL stage.
This code only shows log records, but you can change the object as you need.

The following code will get the object you are looking for

@Override
 public void handleMessage(Message message) throws Fault {
 MessageContentsList objs = MessageContentsList.getContentsList(message);
 if (objs != null && objs.size( ) == 1) {
 Object responseObj = objs.get(0);
 DomainPOJO do = (DomainPOJO)responseObj;
 _logger.info(do.toString());
 }
}
