Please refer following code. /hello/from/JohnDoe will hit the method sayPlainTextHello. When "/hello/from/JohnDoe" is accessed, I want to store the mapped path which is /hello/from/{name} in a log. Please note that I can't modify below code but can add filter, etc. to the app. How to get the mapped path "/hello/from/{name}" ?
#Path("hello")
public class GenericResource {
#GET
#Produces(MediaType.TEXT_PLAIN)
#Path("/from/{name}")
public String sayPlainTextHello(#PathParam("name") String fromName) {
return "Hello Jersey - " + fromName;
}
}

I want to programmatically set the paths on a rest service. I have this bean method which has all the paths.
public List<String> getSubscribeChannelsForRest() { .. }
This is the rest service
#RestController
public class RestMessageController {
#PostMapping(
path = { "#{somebean.getSubscribeChannelsForRest()[0]}",
"#{somebean.getSubscribeChannelsForRest()[1]}",
"#{somebean.getSubscribeChannelsForRest()[2]}"
})
public String processMessage(#RequestBody String messageBody, HttpServletRequest request) { .. }
The above code works but I want to avoid hard coding the array numbers. There is what I tried.
#PostMapping(
path = { "#{somebean.getSubscribeChannelsForRest()}",
This doesn't work because the spring method RequestMappingHandlerMapping.resolveEmbeddedValuesInPatterns(String[] patterns) takes the above SpEL as a single element array. I've checked the trace logs and all the element in the given list get concatenated .
How to upload a file in symfony 4.I have done with the symfony document. I don't know where I have missed something. Its throws error while uploading file give me some clues
REFERED LINK:
https://symfony.com/doc/current/controller/upload_file.html
ERROR:
The file "" does not exist
Entity
public function getBrochure()
{
return $this->brochure;
}
public function setBrochure($brochure)

$this->brochure = $brochure;
return $this;

File upload Listener
class FileUploader
{
private $targetDirectory;
public function __construct($targetDirectory)
{
$this->targetDirectory = $targetDirectory;
}
public function upload(UploadedFile $file)
{
$fileName = md5(uniqid()).'.'.$file->guessExtension();
$file->move($this->getTargetDirectory(), $fileName);
return $fileName;
}
public function getTargetDirectory()
{
return $this->targetDirectory;
}
}
This Symfony tutorial works fine for me so I'll try to explain how and perhaps it will help you or people still looking for an answer, this post getting a bit old.
So first you have to create the FileUploader service in App\Service for better reusability (chapter: Creating an Uploader Service). You can basically copy/paste what they've done here, it works like a charm. Then you need to open your services.yaml in Config folder and explicit your brochure directory:
parameters:
brochures_directory: '%kernel.project_dir%/public/uploads/brochures'
# ...
services:
# ...
App\Service\FileUploader:
arguments:
$targetDirectory: '%brochures_directory%'
Now everything is normally ready to use your FileUploader service.
So if you're in your controller (for example), I guess you want to use it in a form. Thus, you just have to do this (don't forget to use your Service in your Controller):
public function myController(FileUploader $fileUploader)
{
// Create your form and handle it
if ($form isValid() && &form isSubmitted()) {
$file = $myEntity->getBrochure();
$fileName = $this->fileUploader->upload($file);
$myEntity->setBrochure($fileName);
// Form validation and redirection
}
// Render your template
}
One important point I forgot to say. In your FormType, you need to say that the Brochure will be a FileType:
$builder->add('brochure', FileType::class)
But in your entity you have to specify your brochure is stored as a "string":
/**
* #MongoDB\Field(type="string")
*/
protected $brochure;
The reason is your file is getting uploaded and saved in your public/uploads/brochure. But your database is only remembering a string path to reach it.
I hope this will help!
I've been struggling with this for the past 3 days now, I keep getting the following exception when I try upload a file in my spring boot project.
org.springframework.web.multipart.support.MissingServletRequestPartException: Required request part 'file' is not present
I'm not sure if it makes a differance but I am deploying my application as a war onto weblogic,
here is my controller
#PostMapping
public AttachmentDto createAttachment(#RequestParam(value = "file") MultipartFile file) {
logger.info("createAttachment - {}", file.getOriginalFilename());
AttachmentDto attachmentDto = null;
try {
attachmentDto = attachmentService.createAttachment(new AttachmentDto(file, 1088708753L));
} catch (IOException e) {
e.printStackTrace();
}
return attachmentDto;
}
multi part beans I can see in spring boot actuator
payload seen in chrome
Name attribute is required for #RequestParm 'file'
<input type="file" class="file" name="file"/>
You can try use #RequestPart, because it uses HttpMessageConverter, that takes into consideration the 'Content-Type' header of the request part.
Note that #RequestParam annotation can also be used to associate the part of a "multipart/form-data" request with a method argument supporting the same method argument types. The main difference is that when the method argument is not a String, #RequestParam relies on type conversion via a registered Converter or PropertyEditor while #RequestPart relies on HttpMessageConverters taking into consideration the 'Content-Type' header of the request part. #RequestParam is likely to be used with name-value form fields while #RequestPart is likely to be used with parts containing more complex content (e.g. JSON, XML).
Spring Documentation
Code:
#PostMapping(consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public AttachmentDto createAttachment(#RequestPart("file") MultipartFile file) {
logger.info("Attachment - {}", file.getOriginalFilename());
try {
return attachmentService.createAttachment(new AttachmentDto(file, 1088708753L));
} catch (final IOException e) {
logger.e("Error creating attachment", e);
}
return null;
}
You are using multi part to send files so there is nothing much configuration to do to get desired result.
I m having the same requirement and my code just run fine :
#RestController
#RequestMapping("/api/v2")
public class DocumentController {
private static String bucketName = "pharmerz-chat";
// private static String keyName = "Pharmerz"+ UUID.randomUUID();
#RequestMapping(value = "/upload", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA)
public URL uploadFileHandler(#RequestParam("name") String name,
#RequestParam("file") MultipartFile file) throws IOException {
/******* Printing all the possible parameter from #RequestParam *************/
System.out.println("*****************************");
System.out.println("file.getOriginalFilename() " + file.getOriginalFilename());
System.out.println("file.getContentType()" + file.getContentType());
System.out.println("file.getInputStream() " + file.getInputStream());
System.out.println("file.toString() " + file.toString());
System.out.println("file.getSize() " + file.getSize());
System.out.println("name " + name);
System.out.println("file.getBytes() " + file.getBytes());
System.out.println("file.hashCode() " + file.hashCode());
System.out.println("file.getClass() " + file.getClass());
System.out.println("file.isEmpty() " + file.isEmpty());

None of the above solutions worked for me, but when I digged deeper i found that spring security was the main culprit. Even if i was sending the CSRF token, I repeatedly faced the issue POST not supported. I came to know that i was receiving forbidden 403 when i inspected using developer tools in google chrome and saw the status code in the network tab. I added the mapping to ignoredCsrfMapping in Spring Security configuration and then it worked absolutely without any other flaw. Don't know why i was not allowed to post multipart data by security. Some of the mandatory setting that needs to be stated in application.properties file are as follows:
spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=10MB
spring.http.multipart.max-file-size=10MB
spring.http.multipart.max-request-size=10MB
spring.http.multipart.enabled=true
Im using WebApi to upload a file, but when I run
request.Content.ReadAsMultipartAsync(provider)
The file is uploaded but its file name is totally changed.
I read something about that says that it is automatically made for security reasons. Anyway I want to store the file with the real file name. Any idea how to do it?
This simple override fix this issue
public class MyMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
{
public MyMultipartFormDataStreamProvider(string path) : base(path)
{ }
public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
{
// override the filename which is stored by the provider (by default is bodypart_x)
string originalFileName = headers.ContentDisposition.FileName.Trim('\"');
return originalFileName;
}
}
I have an MVC 4 application that sends out multiple emails. For example, I have an email template for submitting an order, a template for cancelling an order, etc...
I have an Email Service with multiple methods. My controller calls the Send method which looks like this:
public virtual void Send(List<string> recipients, string subject, string template, object data)
{
...
string html = GetContent(template, data);
...
}
The Send method calls GetContent, which is the method causing the problem:
private string GetContent(string template, object data)
{
string path = Path.Combine(BaseTemplatePath, string.Format("{0}{1}", template, ".html.cshtml"));
string content = File.ReadAllText(path);
return Engine.Razor.RunCompile(content, "htmlTemplate", null, data);
}
I am receiving the error:
The same key was already used for another template!
In my GetContent method should I add a new parameter for the TemplateKey and use that variable instead of always using htmlTemplate? Then the new order email template could have newOrderKey and CancelOrderKey for the email template being used to cancel an order?
Explanation
This happens because you use the same template key ("htmlTemplate") for multiple different templates.
Note that the way you currently have implemented GetContent you will run into multiple problems:
Even if you use a unique key, for example the template variable, you will trigger the exception when the templates are edited on disk.
Performance: You are reading the template file every time even when the template is already cached.
Solution:
Implement the ITemplateManager interface to manage your templates:
public class MyTemplateManager : ITemplateManager
{
private readonly string baseTemplatePath;
public MyTemplateManager(string basePath) {
baseTemplatePath = basePath;
}
public ITemplateSource Resolve(ITemplateKey key)
{
string template = key.Name;
string path = Path.Combine(baseTemplatePath, string.Format("{0}{1}", template, ".html.cshtml"));
string content = File.ReadAllText(path);
return new LoadedTemplateSource(content, path);
}
public ITemplateKey GetKey(string name, ResolveType resolveType, ITemplateKey context)
{
return new NameOnlyTemplateKey(name, resolveType, context);
}
public void AddDynamic(ITemplateKey key, ITemplateSource source)
{
throw new NotImplementedException("dynamic templates are not supported!");
}
}
Setup on startup:
var config = new TemplateServiceConfiguration();
config.Debug = true;
config.TemplateManager = new MyTemplateManager(BaseTemplatePath);
Engine.Razor = RazorEngineService.Create(config);
And use it:
// You don't really need this method anymore.
private string GetContent(string template, object data)
{
return Engine.Razor.RunCompile(template, null, data);
}
RazorEngine will now fix all the problems mentioned above internally. Notice how it is perfectly fine to use the name of the template as key, if in your scenario the name is all you need to identify a template (otherwise you cannot use NameOnlyTemplateKey and need to provide your own implementation).
Hope this helps.
