RIDC Call to Download File for Spring
1. Method to getFile
public Attachment getWCCFile(String dID,String dDocName,String username) throws IdcClientException, IOException{
IdcContext idcContext= new IdcContext(username);
IdcClient<IdcClientConfig, Protocol, Connection> client = getIdcClient();
DataBinder dataBinderReq = client.createBinder();
dataBinderReq.putLocal("IdcService", "GET_FILE");
dataBinderReq.putLocal("dID", dID);
dataBinderReq.putLocal("dDocName", dDocName);
dataBinderReq.putLocal("allowInterrupt", "1");
dataBinderReq.putLocal("RevisionSelectionMethod", "LatestReleased");
ServiceResponse severiceResponse = client.sendRequest(idcContext, dataBinderReq);
InputStream inputStream = severiceResponse.getResponseStream();
byte[] bytes = IOUtils.toByteArray(inputStream);
Attachment attachment = new Attachment(bytes,0,bytes.length);
attachment.setContentType(severiceResponse.getHeader("Content-Type"));
attachment.setFileName(severiceResponse.getHeader("filename"));
attachment.setContentLength(severiceResponse.getHeader("Content-Length"));
return attachment;
}
2. Attachment Class
public class Attachment {
private byte[] content;
private int offset;
private int length;
private String contentType;
private String extension;
private String fileName;
private String contentLength;
}
3. Spring Controller
@RequestMapping(value = "/getDocument", method = RequestMethod.POST)
public ResponseEntity<byte[]> getDocument(@ModelAttribute("metaDataForm")
MetaData metaData) {
logger.info(" In WCCController.getDocument() ");
try {
Attachment attachment = new RIDCHelper(ridcUrl,ridcPort,ucmPort).getWCCFile(metaData.getdID(), metaData.getdDocName(), metaData.getdDocAuthor());
return getResponse(metaData.getdDocName(),attachment);
} catch (IdcClientException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MimeTypeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
private ResponseEntity<byte[]> getResponse(String dDocName,Attachment attachment) throws MimeTypeException{
logger.info(" In WCCController.getResponse() ");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.parseMediaType(attachment.getContentType()));
Random rand = new Random(System.currentTimeMillis());
MimeTypes allTypes = MimeTypes.getDefaultMimeTypes();
MimeType extMime = allTypes.forName(attachment.getContentType());
String ext = extMime.getExtension();
String randomFileName = "/"+dDocName+"_"+Math.abs(rand.nextLong()) + ext;
headers.setContentDispositionFormData(randomFileName, randomFileName);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<byte[]>(attachment.getContent(), headers, HttpStatus.OK);
return response;
}
4. Data save and retrieval through jdbc utility.
Save:-
public void save(TransactionAction entity) throws Exception {
logger.info(" In TransactionActionDAOImpl.save(TransactionAction) ");
Object []statementParams = new Object[]{entity.getActionid(),entity.getName(),entity.getTitle(),entity.getTitlear(),
entity.getActiontype(),entity.getIsRequired()};
DataWorker dataWorker = new DataWorker(addNew, null,statementParams);
try {
session.executeDataWorkers(dataWorker);
} catch (SQLException e) {
logger.error(" In TransactionActionDAOImpl.save(TransactionAction), Exception : "+e.getMessage());
throw e;
}
}
Update:-
public void update(TransactionAction entity)throws Exception {
logger.info(" In TransactionActionDAOImpl.update(TransactionAction) ");
Object []statementParams = new Object[]{new String(entity.getTitle().toUpperCase().replaceAll("\\s", "")),entity.getTitle(),entity.getTitlear(),
entity.getActiontype(),entity.getIsRequired(),entity.getActionid()};
DataWorker dataWorker = new DataWorker(update, null,statementParams);
try {
session.executeDataWorkers(dataWorker);
} catch (SQLException e) {
logger.error(" In TransactionActionDAOImpl.update(TransactionAction), Exception : "+e.getMessage());
throw e;
}
}
FindAll:-
public TransactionAction findById(BigDecimal id) {
logger.info(" In TransactionActionDAOImpl.findById(BigDecimal), Action Id: "+id);
TransactionAction action = null;
try {
action = getSession().getEntity(findById,new TransactionAction(),id,Constants.ACTIVE);
} catch (SQLException e) {
logger.error(" TransactionActionDAOImpl.findById(BigDecimal), Action Id: "+id+", Exception : "+e.getMessage());
e.printStackTrace();
}
return action;
}
