public class ExtendedJasperReportsMultiFormatView
extends ExtendedAbstractJasperReportsView

Jasper Reports view class that allows for the actual rendering format to be specified at runtime using a parameter contained in the model.

This view works on the concept of a format key and a mapping key. The format key is used to pass the mapping key from your Controller to Spring through as part of the model and the mapping key is used to map a logical format to an actual JasperReports view class. For example you might add the following code to your Controller:

 Map model = new HashMap();
 model.put("format", "pdf");
 

Here format is the format key and pdf is the mapping key. When rendering a report, this class looks for a model parameter under the format key, which by default is format. It then uses the value of this parameter to lookup the actual View class to use. The default mappings for this lookup are:

• csv - JasperReportsCsvView
• html - JasperReportsHtmlView
• pdf - JasperReportsPdfView
• xls - JasperReportsXlsView

The format key can be changed using the formatKey property and the mapping key to view class mappings can be changed using the formatMappings property.

We changed org.springframework.web.servlet.view.jasperreports.JasperReportsMultiFormatView Class into anyframe.web.springmvc.common.jasperreports.ExtendedAbstractJasperReportsMultiFormatView Class in Anyframe.

• In ExtendedJasperReportsMultiFormatView constructor method, we modified View Classes.
• In renderReport method, we checked requestObject from model and set populatedReport into image servlet session.

Since:

1.1.5

Constructor Detail

ExtendedJasperReportsMultiFormatView

public ExtendedJasperReportsMultiFormatView()

Creates a new JasperReportsMultiFormatView instance with a default set of mappings.

Method Detail

setFormatKey

public void setFormatKey(java.lang.String formatKey)

Set the key of the model parameter that holds the format discriminator. Default is "format".

setFormatMappings

public void setFormatMappings(java.util.Properties mappingsWithClassNames)

Set the mappings of format discriminators to view class names. The default mappings are:

• csv - JasperReportsCsvView
• html - JasperReportsHtmlView
• pdf - JasperReportsPdfView
• xls - JasperReportsXlsView

setContentDispositionMappings

public void setContentDispositionMappings(java.util.Properties mappings)

Set the mappings of Content-Disposition header values to mapping keys. If specified, Spring will look at these mappings to determine the value of the Content-Disposition header for a given format mapping.

getContentDispositionMappings

public java.util.Properties getContentDispositionMappings()

Return the mappings of Content-Disposition header values to mapping keys. Mainly available for configuration through property paths that specify individual keys.

renderReport

protected void renderReport(net.sf.jasperreports.engine.JasperPrint populatedReport,
                            java.util.Map model,
                            javax.servlet.http.HttpServletResponse response)
                     throws java.lang.Exception

Locates the format key in the model using the configured discriminator key and uses this key to lookup the appropriate view class from the mappings. The rendering of the report is then delegated to an instance of that view class.

Specified by:

renderReport in class ExtendedAbstractJasperReportsView

Parameters:

populatedReport - the populated JasperPrint to render

model - the map containing report parameters

response - the HTTP response the report should be rendered to

Throws:

java.lang.Exception - if rendering failed
