Jak dostarczyć obiekt połączenia mongodb do JasperFillManager.fillReport() - Spring MongoDB Integracja Jaspera

Pracuję nad przykładem integracji Spring MongoDB Jasper z . Miałem przykład Spring Mysql Jasper, który działa poprawnie. Ten sam program, który zamierzam przekonwertować na mongodbę.Jak dostarczyć obiekt połączenia mongodb do JasperFillManager.fillReport() - Spring MongoDB Integracja Jaspera

kod źródłowy na: https://github.com/test512/spring-mvc-mongo-jasper.git

@note: Śledziłem http://jasperreports.sourceforge.net/api/index.html, ale nie widzę pliku jar do pobrania. Nie ma go w maven repo?

LoadJasperReport.java

     resp.resetBuffer(); 
     resp.setContentType("application/pdf"); 
     resp.setContentLength(bytes.length); 
     ServletOutputStream ouputStream = resp.getOutputStream(); 
     ouputStream.write(bytes, 0, bytes.length); 
     ouputStream.flush(); 
     ouputStream.close(); 
    } 
}

Ten program próbuję przekonwertować do MongoDB jak poniżej, ale nie jestem pewien, w jaki sposób można uzyskać obiektu Connection? Czy istnieje jakiś sposób na uzyskanie obiektu połączenia z mongody lub w inny sposób na napisanie kodu dla jaspisu mongotb?

Teraz widzę problemu na linii:

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, hmParams, conn);

Zmieniłem kod jak poniżej, ale to nie działa. Proszę przewodnika.

W każdym razie udało mi się rozwiązać ten problem teraz. Musisz poniżej zależność:

<!-- but you need one more (secret) from mongoDB site --> 
     <dependency> 
      <groupId>com.jaspersoft.connectors.mongodb</groupId> 
      <artifactId>js-mongodb-datasource</artifactId> 
      <version>0.9.3</version> 
     </dependency>

I

<!-- This is a secret repository for js-mongodb-datasource jar --> 
    <repositories> 
     <repository> 
      <id>MongoJasperRepo</id> 
      <url>http://jaspersoft.artifactoryonline.com/jaspersoft/jaspersoft-repo</url> 
      <releases> 
       <enabled>true</enabled> 
      </releases> 
     </repository> 
    </repositories>

i po prostu stosować poniższy kod. Zrobione!

MongoDbConnection conn = null; 

     try { 
      try { 
       conn = new MongoDbConnection("mongodb://" + mongoHost + ":" + mongoPort + "/" + mongodb, null, null); 
      } catch (JRException e) { 
       System.out.println("JREException : " + e.getMessage()); 
      }

Chyba powinien yuo stworzyć MongoDbConnection (patrz kod źródłowy https://github.com/soluvas/com.jaspersoft.studio.data.mongodb/blob/master/src/com/jaspersoft/mongodb/connection/MongoDbConnection.java) i pamiętaj, aby dodać mocy ścieżce klas (lub jak Maven dobrze) właściwy słoik i słoik log4j (potrzebne dla tej klasy)

może zrobić coś takiego:

String mongoURI = "mongodb://localhost:27017/mybb"; 
MongoDbConnection mongConnection = null; 
Map<String, Object> parameters = new HashMap<String, Object>(); 
try { 
mongConnection = new MongoDbConnection(mongoURI, null, null); 
    parameters.put(MongoDbDataSource.CONNECTION, mongConnection); 
    File jasperFile; 
    jasperFile = new File("JREmp1.jasper"); 
    JasperCompileManager.compileReportToFile("JREmp1.jrxml",  "JREmp1.jasper"); 
    JasperFillManager.fillReportToFile("JREmp1.jasper", parameters); 
    JasperExportManager.exportReportToPdfFile("JREmp1.jrprint"); 
} 
} catch (Exception e) { 
    e.printStackTrace(); 
} finally { 
    if (mongConnection != null) { 
mongConnection.close(); 
    } 
}

Mam nadzieję, że jest przydatna

można go downaload tutaj: https://github.com/soluvas/com.jaspersoft.studio.data.mongodb i nie jest też pom.xml gdzie należy znaleźć repozytorium –

Teraz mam com.jaspersoft.studio.data.mongodb-5.1.1-SNAPSHOT.jar na ścieżce klas. Ale teraz nie widzę MongoDbDataSource.CONNECTION nic w dowolnym pliku jar. Proszę przewodnika. Przesłałem kod src na https://github.com/test512/spring-mvc-mongo-jasper.git –
