    Envers with Custom Reverse Engineering Strategy

    Adam Retter Newbie

      So I am using a custom reverse engineering strategy (by extending org.hibernate.cfg.reveng.DelegatingReverseEngineeringStrategy) with Hibernate Tools to generate my Java Hibernate ORM classes from my Postgres database Schema.

       

      I now want to start using Envers, but I cannot understand how to have my custom reverse engineering strategy or Hibernate tools add the Envers @Audited annotations to my classes.

       

      Any ideas?

       

       

      My Maven config to invoke Hibernate Tools looks like this -

       

                  <plugin>

                      <groupId>org.codehaus.mojo</groupId>

                      <artifactId>hibernate3-maven-plugin</artifactId>

                      <version>2.2</version>

                      <configuration>

                          <componentProperties>

                              <jdk5>true</jdk5>

                              <ejb3>true</ejb3>

                          </componentProperties>

                      </configuration>

                      <executions>

                          <execution>

                              <id>generate-hibernate-java</id>

                              <phase>generate-sources</phase>

                              <goals>

                                  <goal>hbm2java</goal>

                              </goals>

                              <configuration>

                                  <components>

                                      <component>

                                          <name>hbm2java</name>

                                          <outputDirectory>target/generated-sources/hibernate3-classes</outputDirectory>

                                          <implementation>jdbcconfiguration</implementation>

                                      </component>

                                  </components>

                                  <componentProperties>

                                      <reversestrategy>uk.org.adamretter.hibernate.reveng.interfacestratergy.InterfaceReverseEngineeringStrategy</reversestrategy>

                                      <packagename>uk.co.accountablecare.web.orm.generated</packagename>

                                  </componentProperties>

                              </configuration>

                          </execution>

                      </executions>

                      <dependencies>

                         ...

                      </dependencies>

                  </plugin>

          So I managed to do pretty much this by overriding the methods columnToMetaAttributes(...) and tableToMetaAttributes(...). By manipulating the CLASS_SCOPE or GET_SCOPE you can inject your annotations for envers.

           

          However I cannot seem to inject Annotations on get'ers which are mappings to foreign keys, so for example on my ServiceUser Entity (audited), there is a foreign key from Booking Entity (not-audited) -

           

          @OneToMany(fetch=FetchType.LAZY, mappedBy="serviceUser")

              public Set<Booking> getBookings() {

                  return this.bookings;

              }

           

          Now I need to be able to add the @NotAudited annotation to the method, but this does not seem possible through a custom reverse engineering startegy. I did look into the code and it should be possible to add some support for adding in custom annotations in a clean way, but this is way deeper than I want to go. So for the time being I have abandoned reverse engineering strategy.

            I've never tried this, but maybe you can also post on the Hibernate/JBoss Tools forum, with a feature request to be able to add custom annotations more easily.
