我工作的一個春天RESTful Web服務，其中我返回XML文件作爲響應發送。這個XML文件放在eclipse中MAVEN項目的main/resources文件夾中。該服務接受調用者的某些參數，並根據這些參數更新XML文件。該項目在生產服務器中作爲WAR進行部署。在我的本地項目中，我可以看到正在更新的xml文件，但在生產服務器中不是。我怎樣才能在生產服務器上工作？Spring REST Web服務|更新XML和響應
下面是控制器接受傳入請求
@RestController
public class HelloWorldRestController {
@Autowired
UserService userService; // Service which will do all data
// retrieval/manipulation work
@Autowired
DialogServiceXml dialogService;
// Returning an xml file in the response
@CrossOrigin(origins = "*")
@RequestMapping(value = "/getUpdatedDialog", method = RequestMethod.POST, produces = "application/xml")
public ResponseEntity<InputStreamResource> downloadXMLFile(@RequestBody Dialog dialog,
UriComponentsBuilder ucBuilder) throws IOException {
// Update the xml file named : "mor_dialog.xml"
dialogService.updateXml(new StringBuilder(dialog.getClassName()), new StringBuilder(dialog.getResponse()));
// Pick up the updated file from the classpath
ClassPathResource xmlFile = null;
try {
xmlFile = new ClassPathResource("mor_dialog.xml");
} catch (Exception exception) {
exception.printStackTrace();
}
// Code to prevent caching so that always the latest version of the file
// is being sent.
HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.add("Cache-Control", "no-cache, np-store, must-revalidate");
httpHeaders.add("Pragma", "no-cache");
httpHeaders.add("Expires", "0");
//httpHeaders.add("Access-Control-Allow-Origin", "http://nlc-mor-furniture.mybluemix.net");
return ResponseEntity.ok().headers(httpHeaders).contentLength(xmlFile.contentLength())
.contentType(MediaType.parseMediaType("application/octet-stream"))
.body(new InputStreamResource(xmlFile.getInputStream()));
}
}
下面的代碼是解組XML中的類，更新它基於輸入參數，然後編組回

任何代碼，服務器日誌的輸出將需要任何建議/解決方案。你可以提供他們請 –
添加我正在處理的代碼。謝謝 –
