Unable to use JPA Attribute converters in karaf

2020-02-28 Thread Erdbeerheld1990 
Hello,

we are using karaf version 4.2.7 with blueprint. Now the first time we want
to implement an  Attribute Converter
   from JPA in order to
convert the string content of a column to an Object. 

@Converter(autoApply = true)
public class DynamicViewConfigurationConverterJson implements
AttributeConverter {
  
  private final static ObjectMapper objectMapper = new ObjectMapper();

  @Override
  public String convertToDatabaseColumn(DynamicViewConfiguration
dynamicViewConfiguration) {
try {
  return objectMapper.writeValueAsString(dynamicViewConfiguration);
} catch (JsonProcessingException ex) {
  return null;
}
  }

  @Override
  public DynamicViewConfiguration convertToEntityAttribute(String dbData) {
try {
  return objectMapper.readValue(dbData, DynamicViewConfiguration.class);
} catch (IOException e) {
  throw new RuntimeException(e);
}
  }

} 

And this is my entity:

@Entity
@Table(name = "CAIS_DYNAMIC_VIEW")
public class DynamicView {
  private Long id;
  private String viewName;
  private String detailViewRoute;
  private String translationKey;
  private String viewCategory;
  private DynamicViewConfiguration viewConfiguration;

  public DynamicView() {
  }

  @Id
  @GenericGenerator(name = "id_generator", strategy =
"com.cedros.cais.persistence.generator.IdGenerator")
  @GeneratedValue(generator = "id_generator")
  public Long getId() {
return id;
  }

  public void setId(Long id) {
this.id = id;
  }

  @Column(name = "VIEW_NAME", nullable = false)
  public String getViewName() {
return viewName;
  }

  public void setViewName(String viewName) {
this.viewName = viewName;
  }

  @Column(name = "DETAIL_VIEW_ROUTE")
  public String getDetailViewRoute() {
return detailViewRoute;
  }

  public void setDetailViewRoute(String detailViewRoute) {
this.detailViewRoute = detailViewRoute;
  }

  @Column(name = "TRANSLATION_KEY", nullable = false)
  public String getTranslationKey() {
return translationKey;
  }

  public void setTranslationKey(String translationKey) {
this.translationKey = translationKey;
  }

  @Column(name = "VIEW_CATEGORY")
  public String getViewCategory() {
return viewCategory;
  }

  public void setViewCategory(String viewCategory) {
this.viewCategory = viewCategory;
  }

  @Column(name = "VIEW_CONFIGURATION", nullable = false)
  @Convert( converter = DynamicViewConfigurationConverterJson.class)
  public DynamicViewConfiguration getViewConfiguration() {
return viewConfiguration;
  }

  public void setViewConfiguration(DynamicViewConfiguration
viewConfiguration) {
this.viewConfiguration = viewConfiguration;
  }
}


My Unit tests are working fine from spring context. But when i keep the
@Convert annotation and run it in karaf, my DAOs are not starting. They are
waiting for the persistence-Context and fail after some time - Declaritive
Services:

Status: GracePeriod
Blueprint
28.02.20 15:30
Missing dependencies:
(&(osgi.unit.name=caisPersistenceUnit)(objectClass=javax.persistence.EntityManager))
Declarative Services


When i remove the @Convert annotation it is not complaining, but then of
course my attribute converter has not any effect. I would be very pleased
for your help.

Best regards,
Andreas
