问题描述
实际上,我具有该功能,我在其中设置了URL(ip:port/birt/preview?__report=report.rptdesign&__format=pdf¶meters...
)的框架,然后该框架呈现了PDF文件.
Actually, I have that functionality, I got a frame where I set the URL (ip:port/birt/preview?__report=report.rptdesign&__format=pdf¶meters...
) and that frame renders the PDF file.
但是我希望该URL隐藏...
But I want that URL hidden...
我需要使用Spring MVC返回一个PDF文件,但是该PDF是由另一个应用程序生成的.
I need return a PDF file with Spring MVC but that PDF is generated by another application.
这意味着我得到了另一个应用程序(Eclipse Birt Engine),该应用程序通过URL(ip:port/birt/preview?__report=report.rptdesign&__format=pdf¶meters...
)传递参数,并且生成了PDF文件,我需要从控制器中获取该PDF并通过Spring MVC返回.有人可以帮忙吗?
This means I got another app (Eclipse Birt Engine) that I pass the parameters through of an URL (ip:port/birt/preview?__report=report.rptdesign&__format=pdf¶meters...
) and it generates a PDF file, I need from my controller get that PDF and return it with Spring MVC. Could somebody help?
推荐答案
如下所示:
@Controller
@RequestMapping("/generateReport.do")
public class ReportController
@RequestMapping(method = RequestMethod.POST)
public void generateReport(HttpServletResponse response) throws Exception {
byte[] data = //read PDF as byte stream
streamReport(response, data, "my_report.pdf"));
}
protected void streamReport(HttpServletResponse response, byte[] data, String name)
throws IOException {
response.setContentType("application/pdf");
response.setHeader("Content-disposition", "attachment; filename=" + name);
response.setContentLength(data.length);
response.getOutputStream().write(data);
response.getOutputStream().flush();
}
}
