난 내가 website.I에서 파일을 다운로드해야 내 스프링 MVC 프로젝트의 일부로서 컨트롤러 방법을 쓴이 :요청 매핑 occued : Not Available 요청한 자원을
//download resume
//----------------------------------------------------------------------
@RequestMapping(value="/download/{fileName.+}",method=RequestMethod.GET)
public void downloadPDFResource(HttpServletRequest request,
HttpServletResponse response,@PathVariable("fileName") String fileName){
System.out.println("filename i got :"+fileName);
//If user is not authorized - he should be thrown out from here itself
//String fileName="Ente Kadha - Madhavikkutty.pdf";
//Authorized user will download the file
String dataDirectory = request.getServletContext().getRealPath("/WEB-INF/downloads/");
Path file = Paths.get(dataDirectory, fileName);
if (Files.exists(file)) {
response.setContentType("application/pdf");
response.addHeader("Content-Disposition", "attachment; filename=" + fileName);
try {
Files.copy(file, response.getOutputStream());
response.getOutputStream().flush();
} catch (IOException ex) {
ex.printStackTrace();
}
}
else
{
System.out.println("\n\nFile not found!!\n\n");
System.out.println(file);
}
}

다운로드 링크를 클릭, 내가 오류를 얻고있다 : "요청 된 자원을 사용할 수 없습니다": 나는 오류가의 매핑이 생각
WARNING [http-nio-8084-exec-129] org.springframework.web.servlet.DispatcherServlet.noHandlerFound No mapping found for HTTP request with URI [/IntelliLabsWeb/oneProfile/download/Ente Kadha - Madhavikkutty.pdf] in DispatcherServlet with name 'dispatcher'
request.when에서 web.xml의 URL 패턴을/to/*로 변경하면 다른 모든 요청이 작동하지 않습니다.
내 질문은 내가 여기서 만든 실수가 무엇입니까? web.xml에서 url 패턴을 변경해야합니까? 그렇다면 어떻게?
편집 :
내가 그것을 .PDF 확장자로 끝나는 URL로 이동합니다 다운로드 링크를 클릭. 그리고 확장자가 인 요청에 대한 핸들러 나 매핑이 없습니다. 이것이 문제가 될 수 있습니까 ??
는이에 대한 자세한 내용을 설명 할 수있다 : "희망이 HTTP에이 페이지가 :/IntelliLabsWeb/oneProfile"당신이 제안 –
