我正在使用 jasper-reports 4.5.0、spring 3.0.5RELEASE 集成来生成报告。直到现在我以 html、csv、pdf 格式生成。但我的客户也想要 word 格式的报告(.doc 格式)。如何我以这种 .doc 格式生成报告。

对于未来的读者,不推荐使用 setParameter ,您应该使用这样的导出器:
JasperReports 6.1.0
import java.io.File;
//import net.sf.jasperreports.engine.export.JRRtfExporter;
//import net.sf.jasperreports.engine.export.ooxml.JRDocxExporter;
import net.sf.jasperreports.engine.util.JRLoader;
import net.sf.jasperreports.export.SimpleExporterInput;
import net.sf.jasperreports.export.SimpleWriterExporterOutput;
File sourceFile = new File("*.jasper");
JasperPrint jasperPrint = (JasperPrint)JRLoader.loadObject(sourceFile);
File destFile = new File(sourceFile.getParent(), jasperPrint.getName() + ".docx|.rtf");
//JRDocxExporter exporter = new JRDocxExporter();
//JRRtfExporter exporter = new JRRtfExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(destFile));
exporter.exportReport();

只是为了提供基于 Alex 的建议的示例代码:
要使用 JRRtfExporter:
protected byte[] exportReportToRtf(JasperPrint jasperPrint) throws JRException{
JRRtfExporter exporter = new JRRtfExporter();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, baos);
exporter.exportReport();
return baos.toByteArray();
}
与我们 JRDocxExporter 类似:
protected byte[] exportReportToRtf(JasperPrint jasperPrint) throws JRException{
JRDocxExporter exporter = new JRDocxExporter();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, baos);
exporter.exportReport();
return baos.toByteArray();
}
根据评论编辑:
这是 Sprig Fraework 提供的 JaperReport 视图列表。
他们似乎没有专门针对 doc 格式的文件。您可能会通过扩展AbstractJasperReportsSingleFormatView来编写自己的代码。看来您只需要实现该createExporter()
方法。
protected JRExporter createExporter(){
return new JRDocxExporter();
}

基于 JRDocxExporter,您可以扩展AbstractJasperReportsSingleFormatView:
public class CustomJasperWordReportsSingleFormatView extends AbstractJasperReportsSingleFormatView {
@Override
protected void renderReport(JasperPrint populatedReport, Map<String, Object> model, HttpServletResponse response) throws Exception {
super.renderReport(populatedReport, model, response);
}
@Override
protected JRExporter createExporter() {
return new JRDocxExporter();
}
@Override
protected boolean useWriter() {
// TODO Auto-generated method stub
return false;
}
}
并在您使用HttpServletResponseWrapper@Controller
包装响应以获取由 jasper 报告生成的字节数组:
public byte[] getByteArrayWordReport(String jasperViewName, ModelMap model, HttpServletResponse httpServletResponse,HttpServletRequest httpServletRequest) throws Exception{
View view=xmlViewResolver.resolveViewName(jasperViewName, null);
if(view==null){
log.error("Report not found:"+jasperViewName);
}
final ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();
HttpServletResponseWrapper httpServletResponseWrapper=new HttpServletResponseWrapper(httpServletResponse){
@Override
public PrintWriter getWriter() throws IOException {
return new PrintWriter(byteArrayOutputStream);
}
public ServletOutputStream getOutputStream() throws IOException {
return new ServletOutputStream() {
@Override
public void write(int b) throws IOException {
byteArrayOutputStream.write(b);
}
};
}
@Override
public void addCookie(Cookie cookie) {
}
@Override
public void addDateHeader(String name, long date) {
}
@Override
public void setHeader(String name, String value) {
}
@Override
public void addHeader(String name, String value) {
}
@Override
public void setIntHeader(String name, int value) {
}
@Override
public void addIntHeader(String name, int value) {
}
@Override
public void setContentLength(int len) {
}
@Override
public void setContentType(String type) {
}
};
view.render(model, httpServletRequest, httpServletResponseWrapper);
return byteArrayOutputStream.toByteArray();
}
之后,您拥有表示 Word 文档的字节数组。
