I have implemented DeferredResult in spring MVC. It returns the right response in Tomcat8 but when I deployed into weblogic 12.1.3 gives me 404 error. I tried to debug to find out what is going on then at some point handler is looking for view in web-inf directory. I am confused here.
Could you please help me to understand?
I am using Spring
Java 7
Spring 4.2.0.RELEASE
Spring OAuth2
Weblogic 12.1.3
#RequestMapping(value = "/file/{id}")
#ResponseBody
public DeferredResult<ResponseEntity<Resource>> file(#PathVariable String id) {
DeferredResult<ResponseEntity<Resource>> result = new DeferredResult<>();
try {
final ImageObject image = null;
final Resource fileResource = new FileSystemResource(image.getImagePath().replace("E:", "C:"));
final HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
headers.setContentLength(fileResource.contentLength());
result.setResult(new ResponseEntity<>(fileResource, headers, HttpStatus.OK));
} catch (Exception e) {
}
return result;
}
Thanks in advance.
In my case Spring wrongly concatenated a #RequestMapping path of #RestController and #RequestMapping path of a method. #RequestMapping path of #RestController was duplicated in a resulting URI in Spring logs.
The only workaround I've found is to create #RestControllers for each required DeferredResult method without specifying a #RequestMapping path in the methods.
WebLogic 12.2.1.3.0, Spring 4.3.23.

We are using Spring Boot 2.5.2 with Keycloak 14.0. I am trying to log the authorization events in addition to the URL the user called.
I am trying to follow Spring Boot Authentication Auditing Support. The code to retrieve the Request URL is:
private void onAuthorizationFailureEvent(
AuthorizationFailureEvent event) {
Map<String, Object> data = new HashMap<>();
data.put(
"type", event.getAccessDeniedException().getClass().getName());
data.put("message", event.getAccessDeniedException().getMessage());
data.put(
"requestUrl", ((FilterInvocation)event.getSource()).getRequestUrl() );
if (event.getAuthentication().getDetails() != null) {
data.put("details",
event.getAuthentication().getDetails());
}
publish(new AuditEvent(event.getAuthentication().getName(),
AUTHORIZATION_FAILURE, data));
}
When I attempt this I am getting a ClassCastException when calling event.getSource(). The source seems to be a ReflectiveMethodInvocation (to my Controller) and not a FilterInvocation. Can anybody explain this? How do I get the request url?
With Spring Boot 2.3 I was using the following Kotlin code
val mvcResultImage = this.mockMvc!!.perform(MockMvcRequestBuilders.multipart("/somepath)
.file("files[]", imageFile.getBytes())
.characterEncoding("UTF-8"))
.andReturn()
in an integration test for a controller with a function
#PostMapping(path = ["/somepath"],
consumes = [MediaType.MULTIPART_FORM_DATA_VALUE],
produces = [MediaType.APPLICATION_JSON_VALUE])
#ResponseBody
fun createFromBytes(#RequestParam("files[]") file: MultipartFile): ResponseEntity<Any> {
...
}
In 2.3 I was able to handle the request in the controller function whereas in 2.4 the controller function raises a org.springframework.web.multipart.support.MissingServletRequestPartException with the message Required request part 'files[]' is not present and causes HTTP response code 400.
I don't find anything in the migration guide and list of handled issues for this version change.
A rename to file in both controller and request doesn't help, I don't remember why I added [] in the code working with 2.3, but I think it was necessary to make it work.
I'm using Spring Boot through the maven parent mechanism with spring-boot-starter-parent:2.4.1.
This is a known issues in Spring Boot coming from Spring. It's fixed in Spring Boot 2.4.2. The linked issue contains a successfully tested workaround in case you're stuck with 2.4.1: Create MockMultipartFile with MockMultipartFile( String name, #Nullable String originalFilename, #Nullable String contentType, #Nullable byte[] content) (specification of originalFilename matters).
I've got a spring boot application that is defining a RestTemplate bean as follows:
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
Also, pulling in spring-boot-starter-actuator and io.micrometer:micrometer-registry-prometheus.
When I use the injected RestTemplate as follows:
#Autowired
private RestTemplate restTemplate;
private String uriTemplate = "http://my.domain.com/bookstore-api/books";
public List<Book> getBooksByAuthor(String author) {
// create URI for "http://my.domain.com/bookstore-api/books?author={authorId}"
UriComponentsBuilder uriComponentsBuilder = UriComponentsBuilder
.fromUriString(uriTemplate)
.queryParam("author", author);
// make the GET
ResponseEntity<Book[]> responseEntity = restTemplate.getForEntity(uriComponentsBuilder.toUriString(),Book[].class);
// rest ommitted for brevity
}
When getBooksByAuthor("Tolkien") is called, we can then hit /metrics/prometheus and see the following:
http_client_requests_seconds_count{clientName="my.domain.com",method="GET",status="200",uri="/bookstore-api/books?author=Tolkien",} 2.0
http_client_requests_seconds_sum{clientName="my.domain.com",method="GET",status="200",uri="/bookstore-api/books?author=Tolkien",} 0.253227898
This would be fine, except that there are lots of authors out there, and eventually I will get the "too many tags" exception.
I would prefer to have the following (similar to how path variables get templated):
http_client_requests_seconds_count{clientName="my.domain.com",method="GET",status="200",uri="/bookstore-api/books?author={author}",} 2.0
http_client_requests_seconds_sum{clientName="my.domain.com",method="GET",status="200",uri="/bookstore-api/books?author={author}",} 0.253227898
Is this possible to achieve by modifying the way I use UriComponentsBuilder? The closest thing I've found is to define my own RestTemplateExchangeTagsProvider, and override the default to do some crazy regex replacement.
Just fixed same issue in SpringBoot 2.4.5 using:
responseEntity = restTemplate.exchange(
config.getDataUrl(),
HttpMethod.GET,
httpEntity,
new ParameterizedTypeReference<String>() {},
rowId);
where getDataUrl resolves to:
https://data-service-dev.apps.cloud.net/api/hbase/getData?rowId={rowId}
metrics:
http_client_requests_seconds_count{clientName="data-service-dev.apps.cloud.net",method="GET",outcome="SUCCESS",status="200",uri="/api/hbase/getData?rowId={rowId}",} 1.0
...
I have had a same problem. Maybe this information will help you.
In my case restTemplate.setUriTemplateHandler(handler) had overwritten annonymous
MetricsClientHttpRequestInterceptor#createUriTemplateHandler.
And the original url templates had not been stored into memory for prometheus.
DefaultUriBuilderFactory builderFactory = new DefaultUriBuilderFactory();
builderFactory.setEncodingMode(DefaultUriBuilderFactory.EncodingMode.NONE);
customizer.customize(restTemplate);
restTemplate.setUriTemplateHandler(handler);
So,
I changed order of the commands:
restTemplate.setUriTemplateHandler(handler);
customizer.customize(restTemplate);
Please check that there are no setting commands for restTemplate after MetricsClientHttpRequestInterceptor.customize(restTemplate).
Here is my spring controller code..
#RequestMapping(value= "/save_item",
method = RequestMethod.POST,produces="application/json")
public #ResponseBody ModelMap saveItem(ModelMap model,
#RequestParam("id") String itemId,
#RequestParam("name") String itemName) {
model.addAttribute("itemId",itemId);
return model;
}
How can i make a rest client using spring rest tempalte?.
I need to send two parameters from my rest client(id,name).
Anyone Please help me.
Thanks.
You can create a RestTemplate object and execute as this
ResponseEntity<List<City>> result = restTemplate.exchange(
new StringBuilder(URL).append(city).toString(),
HttpMethod.GET, null, responseType);
In this project you can find a maven project with spring-boot and sptring-web that uses this restTemplate snippet and jackson for the json response

I have an issue using Ajax upload with Spring 3 MVC. I understand that I have to configure multipartResolver bean in spring config, which I've done. Than I can have controller like this
#RequestMapping(value ="/settingsSim")
#ResponseBody
public Map uploadSimSettings(#RequestParam(value="qqfile", required=true) MultipartFile settings) {
Map<String, Object> ret = new HashMap<String, Object>();
return ret;
}
The problem is that when I actually send the request to the server (actually valums Ajax file upload does this for me), I get an Internal server error response and nothing is shown in the logs. I am really scratching my head now, as I cannot figure out the problem.
my solution:
#RequestMapping(value = "/create/upload", method = RequestMethod.POST, consumes="multipart/form-data", produces="application/json")
#ResponseBody()
public String handleImageUpload(#RequestParam(value="qqfile", required=true) MultipartFile[] files,
#ModelAttribute(value="files") List<MultipartFile> filesSession) throws IOException, FileUploadException {
if (files.length > 0) {
filesSession.addAll(Arrays.asList(files));
// store the bytes somewhere
return "{\"success\": true}";
}
else {
return "{\"success\": false}";
}
}
#RequestMapping(value = "/create/upload", method = RequestMethod.POST, consumes="application/octet-stream", produces="application/json")
#ResponseBody()
public String handleImageUploadApplication(HttpServletRequest request,
#ModelAttribute(value="files") List<MultipartFile> filesSession) throws IOException, FileUploadException {
if (request.getInputStream() != null) {
// creamos el fichero temporal
File file = File.createTempFile("file", "valumns",
RepositoryData.getRepositoryData());
FileOutputStream fos = new FileOutputStream(file);
// copiamos contenido
Streams.copy(request.getInputStream(), fos, true);
//TODO:
//filesSession.addAll(Arrays.asList(files));
// store the bytes somewhere
return "{\"success\": true}";
}
else {
return "{\"success\": true}";
}
}
#ExceptionHandler(Exception.class)
#ResponseStatus(value = HttpStatus.SERVICE_UNAVAILABLE)
public void handleException(Exception ex) {
log.error("Ocurrio un error en el album", ex);
}
I had the same problem with the fineuploader (valums), and I tried using request.getInputStream() but did not get it to work.
The #ResponseBody annotation worked but I got the whole body with headers. I thought processing that and stripping off the unwanted chunks was not very elegant.
I looked further and found the solution is this post:
problem with spring ajax file upload
Like it is said, I added the bean configuration for the multipart resolver to my spring configuration
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
</bean>
After that, I could easily retrieve my file using
public #ResponseBody Map ajaxUploadFile(#RequestParam MultipartFile qqfile) { ... }
Don't forget to add the Apache commons-io.jar and commons-fileupload.jar libraries in your project to get it to work
When using valums plugin I solved this problem by using #RequestBody Spring annotation.
You could rewrite your code as follows:
#RequestMapping(value ="/settingsSim",method=RequestMethod.POST)
#ResponseBody
public Map uploadSimSettings(#RequestBody String body) {
/*
some controller logic
*/
}
Note that the variable body will contain the contents of the uploaded file. Also there is no method declaration in your example which means that your method will be mapped to GET request.
P.S. I also had this "no multipart boundary" problem when parsing request with Apache Commons. HttpServletRequest#getParts() returns just an empty collection.
#Tomas I encountered same issue while using the same jquery plugin. Please change the Content-Type in the plugin code to xhr.setRequestHeader("Content-Type", "multipart/form-data"); on my plugin its line 1203, after this its now showing a stack trace, however I am encountering another issue where the logs are printing :
Sep 8, 2011 9:43:39 AM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet dispatcher threw exception
org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found
As per my observation the file upload plugin does not send a multipart file but sends a stream. I could get it to work by declaring the controller method to accept filename as request param qqfile and the second parameter as httprequest. I then did further processing using request.getinputstream. Hope that helps!
