First of all, I am new with Spring Boot.
I am not sure if it is possible, but I would like to return the xml response from the external url.
I have this code:
#GetMapping("/myPage")
public void myPage() {
restConfiguration().host("localhost").port(8080);
from("timer://runOnce?repeatCount=1&delay=0")
.to("rest:get:/external-page")
.to("stream:out");
}
myPage() is returning a XML (that's OK). So, now I would like to return the same XML when I do:
curl http://localhost/myPage
I am not sure if I have to use .to("stream:out"), but the curl is returning an empty result.
Can someone help me?
Thanks in advance.
I found the solution, this is how to get the response.
CamelContext context = new DefaultCamelContext();
context.addRoutes(new RouteBuilder() {
public void configure() {
restConfiguration().host(sHost).port(iPort);
from("direct:start")
.setHeader(Exchange.HTTP_METHOD,simple("GET"))
.to("rest:get:/external-page");
}
});
context.start();
ProducerTemplate template = context.createProducerTemplate();
String headerValue = "application/xml";
Map<String, Object> headers = new HashMap<String,Object>();
headers.put("Content-Type", headerValue);
Object result = template.requestBodyAndHeaders("direct:start", null, headers, String.class);
Exchange exchange = new DefaultExchange(context);
String response = ExchangeHelper.convertToType(exchange, String.class, result);
context.stop();
return response;

I am writing a spring 5 web app and my requirement is to get a urlencoded form and in response send url encoded response back
This is Router Function code
#Configuration
public class AppRoute {
#Bean
public RouterFunction<ServerResponse> route(FormHandler formHandler) {
return RouterFunctions.route()
// .GET("/form", formHandler::sampleForm)
// .POST("/form", accept(MediaType.APPLICATION_FORM_URLENCODED), formHandler::displayFormData)
.POST("/formnew", accept(MediaType.APPLICATION_FORM_URLENCODED).and(contentType(MediaType.APPLICATION_FORM_URLENCODED)), formHandler::newForm)
.build();
}
}
and here's my Handler code
public Mono<ServerResponse> newForm(ServerRequest request) {
Mono<MultiValueMap<String, String>> formData = request.formData();
MultiValueMap<String, String> newFormData = new LinkedMultiValueMap<String, String>();
formData.subscribe(p -> newFormData.putAll(p));
newFormData.add("status", "success");
return ServerResponse.ok().contentType(MediaType.APPLICATION_FORM_URLENCODED)
.body(fromObject(newFormData));
}
Here's the error I get
2020-04-07 02:37:33.329 DEBUG 38688 --- [ctor-http-nio-3] org.springframework.web.HttpLogging : [07467aa5] Resolved [UnsupportedMediaTypeException: Content type 'application/x-www-form-urlencoded' not supported for bodyType=org.springframework.util.LinkedMultiValueMap] for HTTP POST /formnew
Whats the issue here. I couldn't find any way to write the url encoded response back.
Could anyone point what's the issue.
Try to refactor your code to functional style:
public Mono<ServerResponse> newForm(ServerRequest request) {
Mono<DataBuffer> resultMono = request.formData()
.map(formData -> new LinkedMultiValueMap(formData))
.doOnNext(newFormData -> newFormData.add("status", "success"))
.map(linkedMultiValueMap -> createBody(linkedMultiValueMap));
return ServerResponse.ok().contentType(MediaType.APPLICATION_FORM_URLENCODED)
.body(BodyInserters.fromDataBuffers(resultMono));
}
private DataBuffer createBody(MultiValueMap multiValueMap) {
try {
DefaultDataBufferFactory factory = new DefaultDataBufferFactory();
return factory.wrap(ByteBuffer.wrap(objectMapper.writeValueAsString(multiValueMap).getBytes(StandardCharsets.UTF_8)));
} catch (JsonProcessingException e) {
throw new IllegalArgumentException("incorrect body");
}
}
My Controller use " org.apache.commons.fileupload " realized the file UPload.
see it:
#PostMapping("/upload")
public String upload2(HttpServletRequest request) throws Exception {
ServletFileUpload upload = new ServletFileUpload();
FileItemIterator iter = upload.getItemIterator(request);
boolean uploaded = false;
while (iter.hasNext() && !uploaded) {
FileItemStream item = iter.next();
if (item.isFormField()) {
item.openStream().close();
} else {
String fieldName = item.getFieldName();
if (!"file".equals(fieldName)) {
item.openStream().close();
} else {
InputStream stream = item.openStream();
// dosomething here.
uploaded = true;
}
}
}
if (uploaded) {
return "ok";
} else {
throw new BaseResponseException(HttpStatus.BAD_REQUEST, "400", "no file field or data file is empty.");
}
}
and my MockMvc code is
public void upload() throws Exception {
File file = new File("/Users/jianxiaowen/Documents/a.txt");
MockMultipartFile multipartFile = new MockMultipartFile("file", new FileInputStream(file));
HashMap<String, String> contentTypeParams = new HashMap<String, String>();
contentTypeParams.put("boundary", "----WebKitFormBoundaryaDEFKSFMY18ehkjt");
MediaType mediaType = new MediaType("multipart", "form-data", contentTypeParams);
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post(baseUrl+"/upload")
.content(multipartFile.getBytes())
.contentType(mediaType)
.header(Origin,OriginValue)
.cookie(cookie))
.andReturn();
logResult(mvcResult);
}
my controller is right , it has successed in my web project,
but I want to test it use MvcMock, it has some mistake, see :
can someOne can help me?
"status":"400","msg":"no file field or data file is empty.","data":null
I don't know why it says my file is empty.
my English is poor, thank you very much if someone can help me.
The MockMvc can be used for integration testing for controllers using Apache Commons Fileupload too!
Import the org.apache.httpcomponents:httpmime into your pom.xml or gradle.properties
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.5.13</version>
</dependency>
Update the code to use MultipartEntityBuilder to build the multipart request on the client, and then serialize the entity into bytes, which is then set in the request content
public void upload() throws Exception {
File file = new File("/Users/jianxiaowen/Documents/a.txt");
String boundary = "----WebKitFormBoundaryaDEFKSFMY18ehkjt";
// create 'Content-Type' header for multipart along with boundary
HashMap<String, String> contentTypeParams = new HashMap<String, String>();
contentTypeParams.put("boundary", boundary); // set boundary in the header
MediaType mediaType = new MediaType("multipart", "form-data", contentTypeParams);
// create a multipart entity builder, and add parts (file/form data)
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
HttpEntity multipartEntity = MultipartEntityBuilder.create()
.addPart("file", new FileBody(file, ContentType.create("text/plain"), file.getName())) // add file
// .addTextBody("param1", "value1") // optionally add form data
.setBoundary(boundary) // set boundary to be used
.build();
multipartEntity.writeTo(outputStream); // or getContent() to get content stream
byte[] content = outputStream.toByteArray(); // serialize the content to bytes
MvcResult mvcResult = mockMvc.perform(
MockMvcRequestBuilders.post(baseUrl + "/upload")
.contentType(mediaType)
.content(content) // finally set the content
.header(Origin,OriginValue)
.cookie(cookie)
).andReturn();
logResult(mvcResult);
}
Can you try the below?
mockMvc.perform(
MockMvcRequestBuilders.multipart(baseUrl+"/upload")
.file(multiPartFile)
).andReturn();
Update:
You need to update the controller to handle the MultipartFile:
#PostMapping("/upload")
public String upload2(#RequestParam(name="nameOfRequestParamWhichContainsFileData")
MultipartFile uploadedFile, HttpServletRequest request) throws Exception {
//the uploaded file gets copied to uploadedFile object.
}
You need not use another library for managing file uploads. You can use the file upload capabilities provided by Spring MVC.
I've written a typical spring boot application, now I want to add integration tests to that application.
I've got the following controller and test:
Controller:
#RestController
public class PictureController {
#RequestMapping(value = "/uploadpicture", method = RequestMethod.POST)
public ResponseEntity<VehicleRegistrationData> uploadPicturePost(#RequestPart("userId") String userId, #RequestPart("file") MultipartFile file) {
try {
return ResponseEntity.ok(sPicture.saveAndParsePicture(userId, file));
} catch (IOException e) {
logger.error(e.getMessage(), e);
}
return new ResponseEntity<>(HttpStatus.NOT_IMPLEMENTED);
}
}
Test:
#Test
public void authorizedGetRequest() throws Exception {
File data = ResourceUtils.getFile(testImageResource);
byte[] bytes = FileUtils.readFileToByteArray(data);
ObjectMapper objectMapper = new ObjectMapper();
MockMultipartFile file = new MockMultipartFile("file", "test.jpg", MediaType.IMAGE_JPEG_VALUE, bytes);
MockMultipartFile userId =
new MockMultipartFile("userId",
"userId",
MediaType.MULTIPART_FORM_DATA_VALUE,
objectMapper.writeValueAsString("123456").getBytes()
);
this.mockMvc.perform(multipart("/uploadPicture")
.file(userId)
.file(file)
.header(API_KEY_HEADER, API_KEY)).andExpect(status().isOk());
}
Testing the controller with the OkHttp3 client on android works seamlessly, but I can't figure out how to make that request work on the MockMvc
I expect 200 as a status code, but get 404 since, I guess, the format is not the correct one for that controller
What am I doing wrong?
It must be a typo.
In your controller, you claim the request URL to be /uploadpicture, but you visit /uploadPicture for unit test.
Can someone provide me a demo of sending pdf files as response ?
Endpoint is
#GET
#Path("/PDFiles")
#WebMethod(operationName = "PDFiles")
public Response pdfiles() {
LOGGER.info("Getting FPodAUMFile.");
return dao.getPDFfiles(CacheKeys.pdffile);
}
DAO would be
public Response getPDFfiles(String pdffile) {
File file_pdf = new File("D:/pdffile.pdf");
// HELP ME SEND THIS PDFFILE.PDF AND COMPLETE THE CODE HERE
}
MTOM Simplifies the way it is sent. Can someone elaborate on using MTOM also ?
You need to specify Content-Disposition header in your response and write the file into the response entity. So for e.g.:
public Response getPDFfiles(String pdffile) {
File filePdf = new File("D:/pdffile.pdf"); //You'll need to convert your file to byte array.
ContentDisposition contentDisposition = new ContentDisposition("attachment;filename=pdffile.pdf");
return Response.ok(
new StreamingOutput() {
#Override
public void write(OutputStream outputStream) throws IOException, WebApplicationException {
outputStream.write(/* Your file contents as byte[] */);
}
})
.header("Content-Disposition", contentDisposition.toString())
.header("Content-Type", "application/pdf")
.build();
}
How to convert a file to byte[] can by found here.
I am trying to evaluate JMSHeader for Spring Integration message using SpEL but it seems to be evaluating to false always even though message has header stamped as true
<si:router expression="headers.jms_redelivered.equals(T(java.lang.Boolean).FALSE) ? 'channel1' : 'channel2' />
JMSXDeliveryCount=10, jms_redelivered=true
Can some one please comment what I am doing wrong here?
Thanks
Works for me:
#Test
public void testRedeliveredHeaderWithSpEL() throws JMSException {
DefaultJmsHeaderMapper mapper = new DefaultJmsHeaderMapper();
javax.jms.Message jmsMessage = new StubTextMessage() {
#Override
public boolean getJMSRedelivered() throws JMSException {
return true;
}
};
Map<String, Object> headers = mapper.toHeaders(jmsMessage);
assertNotNull(headers.get(JmsHeaders.REDELIVERED));
SpelExpressionParser parser = new SpelExpressionParser();
StandardEvaluationContext context = new StandardEvaluationContext();
context.addPropertyAccessor(new MapAccessor());
Expression expression =
parser.parseExpression("jms_redelivered.equals(T(java.lang.Boolean).FALSE) ? 'channel1' : 'channel2'");
assertEquals("channel2", expression.getValue(context, headers, String.class));
}
You really should be sure that you don't lose headers before your <router>.
Maybe you use some <transformer> before <router> which returns whole Message<?> istead of just payload ?
