JasperFillManager.fillReport和mongo？ [英] JasperFillManager.fillReport and mongo?

问题描述

我目前正在关注一个教程（ http://kristantohans.wordpress.com/2010/03/01/new-to-jasperreport-build-your-first-impressive-application-part-2/ ）
他使用java数据库连接（conn）

I'am currently following a tutorial ( http://kristantohans.wordpress.com/2010/03/01/new-to-jasperreport-build-your-first-impressive-application-part-2/ ) and he use a java db connection (conn)

50          try {
51       //Fill the report with parameter, connection and the stream reader    
52              JasperPrint jp = JasperFillManager.fillReport(is, null, conn);

如何在这里连接到mongo？
因为有mongo我有：

How can i do to connect to mongo here ? Because with mongo i have :

Mongo m = new Mongo( "localhost" , 27017 );
DB db = m.getDB( "test" );

和

JasperPrint jp = JasperFillManager.fillReport(is, null, m);

不起作用

谢谢！

推荐答案

您不能直接将Jasper Reports与MongoDB一起用作数据提供者，因为MongoDB的驱动程序不兼容JDBC。

You can't use Jasper Reports with MongoDB as its data provider directly, because MongoDB's driver is not JDBC compatible.

您可以从MongoDB获取数据并将其包装到JRDataSource中，JRDataSourche有一些可用的实现，例如JRBeanArrayDataSource和JRBeanCollectionDataSource。

You can fetch your data from MongoDB and wrap it into an JRDataSource, there are some available implementations of JRDataSourche such as JRBeanArrayDataSource and JRBeanCollectionDataSource.

有关JRDataSource和实现的更多信息，请访问 http://jasperreports.sourceforge.net/ api / index.html
