Spring restTemplate execute( ) POST large files and obtain a response - java

This took me quite a while to work out so I wanted to share it. Most information came from SO and I wanted to consolidate into this one place.
My requirements are to upload files using a RESTFul POST. Due to possibly large files I wanted to stream the files. I obviously want to be able to read the response.
I planned to use Jersey as the REST Server and Spring's RestTemplate as the client (and for testing).
The problem I faced was streaming POSTs and receiving a response. How can I do that? (Rhetorical question - I answer this!)

It's unnecessary to go through all these hoops with a RequestCallback. Simply use a PathResource.
PathResource pathResource = new PathResource(theTestFilePath);
ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, new HttpEntity<>(pathResource), String.class);
Spring will use a ResourceHttpMessageConverter to serialize the file identified by the given Path to the request body. Internally, the Spring 4.x implementation uses a buffer size of 4096 bytes (which is also what IOUtils#copy(..) uses).
Obviously, you can provide the response type you want. The example above expects the response body as a String. With a ResponseEntity, you can access all the response headers with
HttpHeaders responseHeaders = response.getHeaders();

I am using SpringBoot 1.2.4.RELEASE with Jersey being pulled in by:
compile("org.springframework.boot:spring-boot-starter-jersey")
I created the project with the brilliant Spring Starter Project (Spring Tool Suite > New or you can do through a website I believe and no doubt IntelliJ has this capability also). And chose 'Jersey (JAX-RS)' option. In the gradle build.gradle I also added the dependency:
compile('commons-io:commons-io:2.4')
I wrote this server side code.
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URI;
import java.net.URISyntaxException;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;
import org.me.fileStore.service.FileStoreService;
#RestController
#Path("/filestore")
public class FileStoreRestService {
private static Logger logger = LoggerFactory.getLogger(FileStoreRestService.class);
#Autowired
private FileStoreService fileStoreService;
#POST
#Path("upload")
#Consumes(MediaType.APPLICATION_OCTET_STREAM)
#Produces(MediaType.APPLICATION_JSON)
public Response Upload(InputStream stream) throws IOException, URISyntaxException { //
String location = fileStoreService.upload(stream); // relative path
URI loc = new URI(location);
Response response = Response.created(loc).build();
System.out.println("POST - response: " + response + ", :" + response.getHeaders());
return response;
}
Where i had most troubles was in getting a Response with a location.
Firstly I had to handle streaming large files. I followed https://stackoverflow.com/a/15785322/1019307 as you can see in the test below. I was NOT obtaining a Response no matter what I tried with the HttpMessageConverterExtractor as per that post:
final HttpMessageConverterExtractor<String> responseExtractor =
new HttpMessageConverterExtractor<String>(String.class, restTemplate.getMessageConverters());
After finding https://stackoverflow.com/a/6006147/1019307 I wrote:
private static class ResponseFromHeadersExtractor implements ResponseExtractor<ClientHttpResponse> {
#Override
public ClientHttpResponse extractData(ClientHttpResponse response) {
System.out.println("StringFromHeadersExtractor - response headers: " + response.getHeaders());
return response;
}
}
This gave me this test:

private RestTemplate restTemplate = new TestRestTemplate();
#Test
public void testMyMethodExecute() throws IOException {
String content = "This is file contents\nWith another line.\n";
Path theTestFilePath = TestingUtils.getTempPath(content);
InputStream inputStream = Files.newInputStream(theTestFilePath);
String url = base + "/upload";
final RequestCallback requestCallback = new RequestCallback() {
#Override
public void doWithRequest(final ClientHttpRequest request) throws IOException {
request.getHeaders().setContentType(MediaType.APPLICATION_OCTET_STREAM);
IOUtils.copy(inputStream, request.getBody());
}
};
final RestTemplate restTemplate = new RestTemplate();
SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
requestFactory.setBufferRequestBody(false);
restTemplate.setRequestFactory(requestFactory);
ClientHttpResponse response = restTemplate.execute(url, HttpMethod.POST, requestCallback,
new ResponseFromHeadersExtractor());
URI location = response.getHeaders().getLocation();
System.out.println("Location: " + location);
Assert.assertNotNull(location);
Assert.assertNotEquals(0, location.getPath().length());
}
private static class ResponseFromHeadersExtractor implements ResponseExtractor<ClientHttpResponse> {
#Override
public ClientHttpResponse extractData(ClientHttpResponse response) {
System.out.println("StringFromHeadersExtractor - response headers: " + response.getHeaders());
return response;
}
}
I need to refactor much in that test out into some services.

Angular and Spring boot -> POST Request response 403

I have a problem with Spring boot and Angular. I make a POST request which works on POSTMAN and locally but which gives me a 403 in production on tomcat with apache as reverse proxy. But it's working when I am with the embedded tomcat.
I have to try everything soon.
All the solutions I've seen say to disable CSFR but I have no authentication to access my webservice and therefore no spring-security dependency.
I tried anyway but the problem is still there. And in some cases it required me to log in which I don't want to do

Do you have any idea?
If Postman is returning the query, then the problem is probably in the Angular front end. I believe I was getting a 403 error when I tried to send a String from my backend, it had to be wrapped in an object and unwrapped by Angular to be a string in Angular.

Send Multipart and JSON data in a Java Object - Spring Boot Rest

I have a java bean which has both multipart and String data. I am trying to pass it in a rest client call which takes this java bean input and processes it.
Below are my model class, controller and rest client.
On making a call from my rest client , I am getting this exception.
Exception in thread "main" org.springframework.web.client.RestClientException: Could not write request: no suitable HttpMessageConverter found for request type [com.techidiocy.models.NHPdfMergeRequest] and content type [multipart/form-data]

HttpEntity<Candidate> httpEntity = new HttpEntity<Candidate>(candidate, headers);
RestTemplate client = new RestTemplate();
client.postForEntity(serverURL, httpEntity, Resource.class);
}
}
Note: I had also tried to set the header content type as json in rest client and then I am getting all the values as Null in the controller. headers.setContentType(MediaType.APPLICATION_JSON);
I had also searched over the internet for this kind of scenario but I am unable to find a solution for this.
I had also tried to pass all the parameters separately (not as part of java bean) then I am able to make it work.

SpringBoot Rest Controller Integration test always gives 401 unauthorized

I have a rest controller, which has simple CRUD operations. I am trying to write integration test.
Below is my RestController:

My problems:
1.)Wheneever I put breakpoint in Rest Controller, it doesnt' stop there, actually it is not getting invoked.
2.)When I run the test for GET it returns sign-in html page from response.getBody()
3.)When I run the test for POST it returns status 401 unauthorized
tried numerious possible solutions on google
even disabled spring security by commenting the the configuration still it doesn't work.
I can call the same Rest Controller from my Unit test and can stop the breakpoints.
My security configurations:-
package com.gasx.corex.scheduler.server;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import com.gasx.corex.ext.user.domain.DefaultRoles;
#Configuration
#EnableWebSecurity
#Order(1)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
// #formatter:off
httpSecurity.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.httpBasic().and()
.authorizeRequests()
.antMatchers("/gasx/**").hasAnyAuthority(DefaultRoles.ROOT.getName(), DefaultRoles.ADMIN.getName(), DefaultRoles.ACTUATOR.getName())
.antMatchers("/webjars/**").hasAnyAuthority(DefaultRoles.ROOT.getName(), DefaultRoles.ADMIN.getName(), DefaultRoles.ACTUATOR.getName())
.antMatchers("/monitor/**").hasAnyAuthority(DefaultRoles.ROOT.getName(), DefaultRoles.ACTUATOR.getName())
// dev urls
.antMatchers("/h2-console/**").hasAuthority(DefaultRoles.ROOT.getName())
.antMatchers("/swagger*/**","/v2/**").hasAnyAuthority(DefaultRoles.ROOT.getName(), DefaultRoles.ADMIN.getName())
.anyRequest().denyAll();
// #formatter:on
httpSecurity.csrf().disable();
httpSecurity.headers().frameOptions().disable();
}
}
Tried one more thing, added below class to my package :-
package com.gasx.corex.ext.scheduler.integrationtest.domain;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
#Configuration
public class AllowAnonymousWebAccess extends WebSecurityConfigurerAdapter {
#Override
public void configure(HttpSecurity web) throws Exception {
web.antMatcher("**/*").anonymous();
}
}
and now it gives 404.
I don't know anything about this project's SecurityConfiguration (you should provide some more information about it), but I think that you should provide some authorization data (Like a JWT in the Authorization header, or so)
Could you give me some more information about the SecurityConfig? (look for org.springframework.security.config.something.something... imports )
EDIT
I took a look at your code, and actually this part
httpSecurity.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.httpBasic().and()
.authorizeRequests()
.antMatchers("/gasx/**").hasAnyAuthority(DefaultRoles.ROOT.getName(), DefaultRoles.ADMIN.getName(), DefaultRoles.ACTUATOR.getName())
is protecting your API with an httpBasic type authorization. You shold provide the credentials in the header to test your application.

Can anyone please tell me what i need to do in the else part to convert the response i am getting as a file and safe that as a file in my java code.
Change your method return type from "File" to "byte[]" and this will work.
else {
byte[] responseFile = (File)response.body().bytes();
return responseFile;
}
use the byte[] from body() to construct an inputstream. use this inputstream to write into a file. response header would let you know the the data type and define the file type accordingly

Android: Call to Spring MVC Restful WebService

I have a restful web service which is written by using spring. Now I want to call it from my android application.
Unfortunately I am familiar with retrofit.
This is one of my method in restful web service.
import com.example.service.RosterDetailService;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
#RestController
#RequestMapping(value = "/api/v1/roster")
public class RosterDetailManagement {
private final Logger logger = LoggerFactory.getLogger(RosterDetailManagement.class);
#Autowired
private RosterDetailService rosterDetailService;
#RequestMapping(value = "/details/getGuardRecords", method = RequestMethod.POST)
#ResponseBody
public List<Map<Object, Object>> getRosterDetailsByGuardEmailAndType(#RequestBody ObjectNode params) {
logger.info("-----------RosterDetailManagement, getRosterDetailsByGuardEmailAndType 1");
Map<Object, Object> response = new HashMap<>();
String guardEmail = params.get("guardEmail").asText();
String status = params.get("status").asText();
return rosterDetailService.getRosterDetailsByGuardEmailAndType(guardEmail, status);
}
}
Now I want detailed steps to call this restful web service in android.
Can anyone help me ?
