How to use REST Assured to upload a file?

I wrote a service which can upload a file to the server, and now I'm writing it's integration test with REST Assured. The functional code is as following:
/* Upload a new document */
#RequestMapping(method = RequestMethod.POST)
public ResponseEntity uploadDocument(#RequestPart("file") final MultipartFile file, final HttpServletRequest request) throws IOException {
final String id = documentService.saveDocument(file);
final String url = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + "/documents/" + id;
return ControllerUtil.resourceCreatedMessage(id, url);
}
To use this service, I always upload a file in Postman, and I didn't add "Content-Type = multipart/form-data" in the Headers, it works perfectly:
If I add the header info "Content-Type = multipart/form-data", I will get the message that "400 - Request is not a multipart request, see details for more information". This part also confused me because in the upper image you can see I'm sending a file in "form-data", how could it not be a multipart request?
Anyway, I am writing the integration test:
#Test
public void testDocuments() throws URISyntaxException {
// Test post a document.
given().multiPart("file", new File(LOCATE_TO_THE_TEST_HTML_FILE))
.expect().statusCode(201).when()
.post(HOST + "/documents");
}
but I got the 415 error:
java.lang.AssertionError: 1 expectation failed.
Expected status code <201> doesn't match actual status code <415>.

I tried to add ".contentType("multipart/form-data")" but the same error occured. Can anyone help me?

Finally found the reason that I should specify the data type of the file in the following way:
.multiPart("file", new File(TestUtil.getFileURI("/examples/help.html")), "text/html")

This is a way where I can send the video in post API using multipart.
File file = new File("File Path");
String endpoint = "/api/v3/abc";
RestAssured.baseURI = "http://dummy.com/";
Response res = given()
.formParam("token", "eacca99696ac5")
.multiPart("media_url", file,"application/json")
.when().post(endpoint);

So In my point I needed to upload 2 files and also Json file
This how i success to solve it:
when file1 and file2 are the Path to the files
public static Response Post(JSONObject body, String URL, String file1, String file2) {
try {
return RestAssured.given().baseUri(URL).urlEncodingEnabled(false)
.accept("application/json, text/plain, */*")
.multiPart("data",body,"application/json")
.multiPart("file[0]", new File(file1),"multipart/form-data")
.multiPart("file[1]", new File(file2),"multipart/form-data")
.relaxedHTTPSValidation().when().post();
} catch (Exception e) {
System.out.println(e);
return null;
}
}

I have checked for all abstract classes but all the methods are defined. Please let me know if anybody can help me in solving this error.

void com.businessobjects.reports.sdk.JRCCommunicationAdapter.setProductLocale(Locale)
This method is concrete in the version of the library you used to compile your code, so your IDE was happy to compile a call reference to it.
The library present in the deployment location is a different version in which this method is abstract.
This is described in the Javadoc for AbstractMethodError:
Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

java.lang.NoClassDefFoundError on classloader from external jar on a repo

I am trying to load the external jar and create a structure of all the classes from that jar.
Currently, the jar is using a dependency on a different location on the repo.
Accessed jar is located at someurl/com/xyz/mystuff2.jar
Accessed jar mystuff1.jar is dependent on someurl/com/abc/mystuff1.jar.
I tried the following.
try {
u = new URL("jar", "", this.url /* Some url*/+ "!/");
URL[] urls = { u };
URLClassLoader cl = URLClassLoader.newInstance(urls);
Enumeration<JarEntry> entries = this.jarFile.entries();
while (entries.hasMoreElements()) {
JarEntry entry = entries.nextElement();
/* Soft checks to make sure it is not pulling an inner class
*/
if (entry.isDirectory() || !entry.getName().endsWith(".class")
&& !entry.getName().contains("$")) {
continue;
}
String className = entry.getName().substring(0,
entry.getName().length() - 6);
className = className.replace('/', '.');
try {
#SuppressWarnings("unused")
Class<?> c = cl.loadClass(className); /*It errors while
loading a class that are extending classes from mystuff.jar*/
} catch (ClassNotFoundException e) {
logger.error("ERROR: Classes were not loaded properly "
+ e.getMessage());
} catch (NoClassDefFoundError e) {
logger.error("ERROR: Classes definition was not found "
+ e.getMessage());
}
}
} catch (MalformedURLException e) {
logger.error("ERROR : There is an issue while accessing the
URL"+ e.getMessage());
}
I am certainly missing a point here, since the jar is already compile and deployed, it should have the bindings from mystuff1 already. Also, given that the extended classes are abstract, what could be an alternative to get the classes loaded or know about them.
My goal is to able to retrieve all the classes, those that extends my BaseClass.class, through reflection and perform create some meaningful structure.
Edit:
Used aliases.

How to implement Redis Multi-Exec by using Spring-data-Redis

All Spring Configuration is written properly. Non-Multi-Exec Redis operations work perfectly.
#Autowired
#Qualifier("stringRedisTemplate")
StringRedisTemplate template;
void test(){
template.multi();
template.boundValueOps("somevkey").increment(1);
template.boundZSetOps("somezkey").add("zvalue", timestamp);
template.exec();
}
After running above code through Junit Test, Exceptions are thrown.

I check redis server, the above two commands have been executed and the result is correct. So the problem comes at last line of the code (template.exec()). When underlying JedisClient try to get multibulk response from EXEC, it seems to throw NullPointerException
I use spring-data-redis 1.0.0.RELEASE
Thanks for help.

The reason for the exception is probably that the Spring template implementation does not reuse the same connection for .multi() and .exec(). You can try to use execute() via a callback:
private RedisTemplate template = ...;
template.execute(
new RedisCallback() {
#Override
public Object doInRedis(RedisConnection connection)
throws DataAccessException {
connection.multi();
//do whatever you need, like deleting and repopulating some keys
connection.expire(CHANNEL_KEY.getBytes(), EXPIRE_SECS);
connection.exec();
return null;
}
}
);

template.setEnableTransactionSupport(true);
maybe you can use this to enable transaction

Piotr is right. You need to put it into SessionCallback.
Here is a quick summary of doing transactions with Spring Data Redis:
https://github.com/eric-wu/dashboard/wiki/3.-Redis-Transactions-via-Spring-Data-Redis
For your case, scroll down and look at "Optimistic locking using WATCH, MULTI, and EXEC".

Look at the implementatin of org.springframework.data.redis.support.collections.CollectionUtils.rename(K, K, RedisOperations<K, ?>)
and read about transaction details here
static <K> void rename(final K key, final K newKey, RedisOperations<K, ?> operations) {
operations.execute(new SessionCallback<Object>() {
#SuppressWarnings("unchecked")
public Object execute(RedisOperations operations) throws DataAccessException {
do {
operations.watch(key);
if (operations.hasKey(key)) {
operations.multi();
operations.rename(key, newKey);
} else {
operations.multi();
}
} while (operations.exec().isEmpty());
return null;
}
});
}
Note : While loop is important
