Hola a todos,

Tengo un custom pdf extractor definido en custom-metadata-extrators-context.xml

<bean id="extracter.pdf" class="es.org.extractor.PDFCustomExtractor" parent="baseMetadataExtracter" >
        <property name="inheritDefaultMapping">
            <value>true</value>
        </property>
      <property name="mappingProperties">
            <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
               <property name="location">
                  <value>classpath:alfresco/extension/custom-pdf-extractor-mappings.properties</value>
               </property>
            </bean>
        </property>
    </bean>‍‍‍‍‍‍‍‍‍‍‍‍

Hasta ahora, he trabajado con la versión Enterprise 3.1  y me ha funcionado todo correctamente, pero hemos actualizado a la versión 3.3 y el extractor ya no funciona… alguna idea??

Por cierto,

Voy a hacer mi pequeña aportación y os posteo aqui el extractor por si a alguien le interesa

public class PDFCustomExtractor extends AbstractMappingMetadataExtracter
{

  private static final String KEY_KEYWORDS = "keywords";
  public static String[] SUPPORTED_MIMETYPES = { "application/pdf" };
  private static Log log = LogFactory.getLog(PDFCustomExtractor.class);
  public PDFCustomExtractor()
  {
    super(new HashSet(Arrays.asList(SUPPORTED_MIMETYPES)));
  }

&nbsp; public Map<String, Serializable> extractRaw(ContentReader reader)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; pdf = PDDocument.load(is);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (pdf.isEncrypted()) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //break label337;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PDDocumentInformation docInfo = pdf.getDocumentInformation();

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; putRawValue("author", docInfo.getAuthor(), rawProperties);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (pdf != null) {

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; pdf.close(); } catch (Throwable e) { e.printStackTrace(); }

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp; }

&nbsp;&nbsp;&nbsp; log.info("\n\nPropiedades de vuelta:" + rawProperties.toString() + "\n");
 

&nbsp;&nbsp;&nbsp; return rawProperties;
&nbsp; }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

En los keywords del pdf vendrian los datos separados por ; de la siguiente manera:

CODIGO=12345;FACTURA=fac_311;NOMBRE=XXXX

y el custom-pdf-extractor-mappings.properties seria algo como:

namespace.prefix.dm=extension.miModelo
CODIGO=dm:codigo
FACTURA=dm:factura
NOMBRE=dm:nombre
‍‍‍‍‍

Un saludo!
