Class AbstractJasperReportsSingleFormatView

java.lang.Object
  org.springframework.context.support.ApplicationObjectSupport
      org.springframework.web.context.support.WebApplicationObjectSupport
          org.springframework.web.servlet.view.AbstractView
              org.springframework.web.servlet.view.AbstractUrlBasedView
                  org.springframework.web.servlet.view.jasperreports.AbstractJasperReportsView
                      org.springframework.web.servlet.view.jasperreports.AbstractJasperReportsSingleFormatView

All Implemented Interfaces:: BeanNameAware, InitializingBean, ApplicationContextAware, View

Direct Known Subclasses:: JasperReportsCsvView, JasperReportsHtmlView, JasperReportsPdfView, JasperReportsXlsView

public abstract class AbstractJasperReportsSingleFormatView
extends AbstractJasperReportsView
extends AbstractJasperReportsView

Extends AbstractJasperReportsView to provide basic rendering logic for views that use a fixed format, e.g. always PDF or always HTML.

Subclasses need to implement two template methods: createExporter to create a JasperReports exporter for a specific output format, and useWriter to determine whether to write text or binary content.

Since:: 1.1.5
Author:: Rob Harrop, Juergen Hoeller
See Also:: createExporter(), useWriter()

Method Summary

protected abstract net.sf.jasperreports.engine.JRExporter createExporter()
          Create a JasperReports exporter for a specific output format, which will be used to render the report to the HTTP response.

protected void renderReport(net.sf.jasperreports.engine.JasperPrint populatedReport, Map model, HttpServletResponse response)
          Perform rendering for a single Jasper Reports exporter, that is, for a pre-defined output format.

protected abstract boolean useWriter()
          Return whether to use a java.io.Writer to write text content to the HTTP response.

Method Detail

renderReport

protected void renderReport(net.sf.jasperreports.engine.JasperPrint populatedReport,
                            Map model,
                            HttpServletResponse response)
                     throws Exception

Perform rendering for a single Jasper Reports exporter, that is, for a pre-defined output format.

Specified by:: renderReport in class AbstractJasperReportsView

Parameters:: populatedReport - the populated JasperPrint to render; model - the map containing report parameters; response - the HTTP response the report should be rendered to
Throws:: Exception - if rendering failed
See Also:: AbstractView.getContentType(), ServletResponse.setContentType(java.lang.String), ServletResponse.setCharacterEncoding(java.lang.String)

createExporter

protected abstract net.sf.jasperreports.engine.JRExporter createExporter()

Create a JasperReports exporter for a specific output format, which will be used to render the report to the HTTP response.

The useWriter method determines whether the output will be written as text or as binary content.

See Also:: useWriter()

useWriter

protected abstract boolean useWriter()

Return whether to use a java.io.Writer to write text content to the HTTP response. Else, a java.io.OutputStream will be used, to write binary content to the response.

See Also:: ServletResponse.getWriter(), ServletResponse.getOutputStream()
