ext使用SenchaArchitect开发
后台用的jersey
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response upload(@NotBlank @FormDataParam("SID") String sid, @NotNull @FormDataParam("size") Long size,
@NotNull @FormDataParam("dmsFileId") Long dmsFileId, @FormDataParam("file") InputStream fileInputStream,
@FormDataParam("file") FormDataContentDisposition contentDispositionHeader) {
try {
Boolean valid = sessionsService.checkSessionsValid(sid);
if (valid == null) {
throw new Exception("session not exist !");
}
if (!valid) {

}
// Get Configuration
String names[] = { "system.dms.upload.destFolder", "system.dms.upload.maxFilesizeInBytes",
"system.dms.upload.tempFolder", "system.dms.upload.allowed", };
Map configurations = configurationsService.getSystemConfigurationsByName(names);

// Create Directorys

}
File tempDirFile = new File(tempDir);

}
Sessions session = sessionsService.getSessions(sid);

// Check dmsFileId if exist

return Response.ok("ok").build();

log.error(ExceptionUtils.getFullStackTrace(e));

}
}
在最外层的window上添加代码
onMainViewportAfterRender: function(component, eOpts) {
//drage and drop file to upload in explorer file win
window.ondragenter = function(e)
{
e.preventDefault();
};
window.ondragover = function(e)
{
e.preventDefault();
};
window.ondrop = function(e)
{
e.preventDefault();
};
window.ondragleave = function(e)
{
e.preventDefault();
};
//xxxxxx
}
在文件导航window上添加dropFileToUpload方法
{ localStorage.setItem('dmsId',result);
var fd = new FormData();
fd.append("file", tempfile);
fd.append("SID", localStorage.getItem('sid'));
fd.append("size", file.size);
fd.append("dmsFileId",result);
var xhr = new XMLHttpRequest();

var failedFileSize = Number(localStorage.getItem("failedFileSize"));
successFileSize++;
localStorage.setItem("successFileSize",successFileSize);
if((successFileSize+failedFileSize)==filesSize){
refreshFileList.call(controller,parentnode.data.folderId,arguments);
}else{
dropFileToUpload(file, controller, tree);
}
} , false);
xhr.upload.addEventListener("error", function(){
var successFileSize = Number(localStorage.getItem("successFileSize"));
var filesSize = Number(localStorage.getItem("filesSize"));
var failedFileSize = Number(localStorage.getItem("failedFileSize"));

dropUploadFailed.call(controller,arguments);
if((successFileSize+failedFileSize)==filesSize){
refreshFileList.call(controller,parentnode.data.folderId,arguments);
}else{
dropFileToUpload(file, controller, tree);
}
}, false);
xhr.open("POST", "../../../rest/FileExplorerPortal/upload");
xhr.send(fd);
}
refreshFileList: function(folderID, evt) {
var progressBar = this.getView().lookupReference('dropFileToUploadProgressBar');
if(progressBar.isVisible()){
progressBar.hide();
}
progressBar.setValue(0);
progressBar.updateText('0%');
