Question

我需要将一个对象传递给我的jasper报告页面。当我发送列表时它可以正常工作，但是当我发送一个像下面的代码这样的对象时，它不起作用。我怎么能这样做？

报告制作方法代码：

// generatePdfReport
@RequestMapping(method = RequestMethod.GET, value = "/report/{id}")
public ModelAndView generatePdfReport(@PathVariable(value = "id") Long id, ModelAndView modelAndView)
        throws JRException {

    LOG.info("--------------generate PDF report----------");

    Map<String, Object> parameterMap = new HashMap<String, Object>();

    java.util.List<Node> nodeList = new ArrayList<Node>();
    JRDataSource JRdataSource = new JRBeanCollectionDataSource(nodeList);

    Node node = nodeService.getOne(id);
    nodeList.add(node);
    parameterMap.put("datasource", JRdataSource);

    // pdfReport bean has ben declared in the spring configuration
    modelAndView = new ModelAndView("pdfReport", parameterMap);

    return modelAndView;

}

我已经用以下代码解决了我的问题，感谢所有人：

// generatePdfReport single node
@RequestMapping(method = RequestMethod.GET, value = "/report/{id}")
public ModelAndView generatePdfReport(@PathVariable(value = "id") Long id, ModelAndView modelAndView)
        throws JRException {

    LOG.info("--------------generate PDF report----------");

    Map<String, Object> parameterMap = new HashMap<String, Object>();

    java.util.List<Node> nodeList = new ArrayList<Node>();
    nodeList.add(nodeService.getOne(id));

    JRDataSource JRdataSource = new JRBeanCollectionDataSource(nodeList);

    parameterMap.put("datasource", JRdataSource);

    // pdfReport bean has ben declared in the spring configuration
    modelAndView = new ModelAndView("nodesReport_PDF", parameterMap);

    return modelAndView;

}
