JasperFillManager.fillReport() - स्प्रिंग मोंगोडीबी जैस्पर एकीकरण

Question

पर मैं mongodb के कनेक्शन ऑब्जेक्ट को कैसे प्रदान करूं स्प्रिंग मोंगो डीबी जैस्पर एकीकरण उदाहरण पर काम कर रहा हूं। मेरे पास स्प्रिंग माईस्क्ल जैस्पर उदाहरण है जो ठीक काम कर रहा है। एक ही कार्यक्रम मैं mongodb के लिए रूपांतरित करने के लिए देख रहा हूँ।

@Note: मैं http://jasperreports.sourceforge.net/api/index.html पीछा किया, लेकिन मैं जार फ़ाइल डाउनलोड करने के लिए देख नहीं है। यह मेवेन रेपो में मौजूद नहीं है?

इस कार्यक्रम मैं नीचे की तरह MongoDB के लिए कन्वर्ट करने के लिए कोशिश कर रहा हूँ, लेकिन मुझे यकीन है कि मैं कैसे कनेक्शन वस्तु प्राप्त कर सकते हैं नहीं कर रहा हूँ? क्या मोंगोडब या कनेक्शन के लिए कोड लिखने के किसी अन्य तरीके से कनेक्शन ऑब्जेक्ट प्राप्त करने का कोई तरीका है?

अब मैं लाइन पर समस्या का हल नहीं:

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

मैं नीचे, लेकिन इसके काम नहीं कर रहा है जैसे कोड बदल दिया है। कृपया गाइड करें।

Answer 1

है उपयोगी

वैसे भी मैं अब इस समस्या को हल करने में सक्षम था। आप निर्भरता नीचे की जरूरत है:

<!-- 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> 

और

<!-- 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> 

और बस नीचे दिए गए कोड का इस्तेमाल किया। हो गया !!

MongoDbConnection conn = null; 

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

Answer 2

मुझे लगता है कि yuo बनाना चाहिए एक MongoDbConnection (स्रोत कोड https://github.com/soluvas/com.jaspersoft.studio.data.mongodb/blob/master/src/com/jaspersoft/mongodb/connection/MongoDbConnection.java देखें) और अपने classpath के तहत जोड़ने के लिए याद (या के रूप में Maven द्वारा अच्छी तरह से) सही जार और log4j जार (उस वर्ग द्वारा आवश्यक)

आप कुछ इस तरह कर सकते हैं:

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(); 
    } 
} 

मुझे आशा है कि यह एंजेलो
