This is regarding to access a POST api using rest template. I'm getting org.springframework.web.client.HttpClientErrorException: 400 null.
I'm adding more details classes on this.
public List<DropPointData> getTargetLocations(List<String> validDrops) throws RestInternalException {
RestTemplate restTemplate = new RestTemplate();
// ResponseEntity<DropPoint[]> responseEntity = null;
URI uri = null;
String list = validDrops.toString();
ResponseEntity<List<DropPoint>> rateResponse = null;
try {
uri = new URI("http://localhost:8082/"+"droppoints");
} catch (URISyntaxException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
ResponseEntity<DropPointData[]> responseEntity;
try {
HttpHeaders headers = new HttpHeaders();
headers.add("Accept", MediaType.APPLICATION_JSON_VALUE);
headers.add("Content-Type", MediaType.APPLICATION_JSON_VALUE);
RouteDropPoint rd = new RouteDropPoint();
rd.setDropPointList(validDrops);
HttpEntity<Object> requestEntity = new HttpEntity<Object>(rd,headers);
System.out.println("Calling location in RestService" );
responseEntity = restTemplate.postForEntity(uri,requestEntity,DropPointData[].class);
} catch (RestClientException e) {
e.printStackTrace();
System.out.println(e.getMostSpecificCause());
throw new RestInternalException("Exception while calling TeamMemberModels :"+uri+","+uri.getPath());
}
/* if(responseEntity.g<=0){
throw new RestInternalException("TeamMemberModels Error. Body : "+responseEntity.toString()+ " and URI : "+uri);
}*/
logger.info("TeamMemberModel Response: {}",responseEntity.toString());
List<DropPointData> response =Arrays.asList( responseEntity.getBody());
return response;
}
public class RouteDropPoint {
List<String> dropPointList;
}
public class RouteDropPoint {
List<String> dropPointList;
}
Earlier the request body was List<String>.I was getting this error. So I kept this list into an object. Still there is no difference in this.
Can anyone please suggest what wrong am I doing here?

Your request formatting is incorrect, hence you are getting 400 errors in both cases. Refer https://stackoverflow.com/a/19671511/945214. Read the server side documentation on the exact request format. Use Gson library in case JSON is expected. Refer http://tutorials.jenkov.com/java-json/gson.html#generating-json-from-java-objects

I'm trying to solve an error of "Invalid Column Name Exception" after calling Stored Procedure from java with hibernate.
My Procedure select data from two tables, ari_immatricule , art_article. both of them has a column called code_art. but the procedure returns instead a param called #P_CODE_ARTI.
Here is my Entity
public class ArticleEntity implements Serializable {
#Id
private Integer code;
private String libelle;
}
NamedProcedure
#StoredProcedureParameter(mode = ParameterMode.OUT, name = "#P_CODE_ARTI", type = Integer.class)
Mapping.
#FieldResult(name = "code", column = "#P_CODE_ARTI")
Stored procedure :
CREATE PROCEDURE S0_CONT_APT_codebarre
( #P_CODE_IMMA char(20),
#P_CODE_ARTI int output,
#P_TAILLE_ATA char(4) output,
#P_POIDS_ATA numeric(6,0) output,
#P_CODE_FAM char(6) output,
#P_TIME_STAMP_ARI timestamp output,
#P_CODE_PTL_CAR char(6) output,
#P_CODE_PTL int output,
#P_CODE_SRV int output,
#P_CODE_EXP int output,
#P_INDIC_SERVI_STT bit output,
#P_NB_LAV_MAX smallint output,
#P_NB_LAV_ARI smallint output,
#P_CODE_TOU tinyint output
)
AS
DECLARE
#ERR_VALUE int,
#NB_ROWS int
DECLARE #P_IND_ARI_SUP bit,
#P_CODE_ATP numeric(10,0)
SELECT
#P_CODE_ARTI = ari.code_arti,
#P_TAILLE_ATA = ari.taille_ata,
#P_POIDS_ATA = art.poids_moy_article,
#P_TIME_STAMP_ARI = ari.time_stamp,
#P_CODE_FAM = art.code_fam,
#P_IND_ARI_SUP = ari.ind_ari_sup,
#P_CODE_ATP = ari.code_atp,
#P_NB_LAV_MAX = art.nb_lav_max,
#P_NB_LAV_ARI = ari.nbre_lav_ari
FROM
ari_arti_immatricule ari,
art_article art
WHERE
ari.code_imma = #P_CODE_IMMA
AND art.code_arti = ari.code_arti
As a Result i get the value of #_CODE_ARTI but i still have the error in the log file, I'm using Sybase for Database.

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 4 years ago.
I'm trying to extract some ads from an website and while doing this I also need to get the last page number of those ads.
String number = "";
Document page = Jsoup.connect("https://www.link.com/cars/" + URLEncoder.encode(query, "UTF-8"))
.userAgent(USER_AGENT).get();
number = page.select(".page").last().text();
if (number == null) {
pageFinalNumber = 1;
} else {
pageFinalNumber = Integer.parseInt(number);
}
My problem is that if the ads are not placed over more than a page the number variable would be null and my app will crash with null pointer exception. I don't know how i should deal with this because I've tried solving the problem with a simple if but it still throws that exception.
This is the stack trace:

Not knowing the rest of the code and without a stack trace its hard to help but I suspect you could do something like this
try {
number = page.select(".page").last().text();
} catch(NullPointerException e) {
pageFinalNumber = 1;
}
However, if there is something you can do to avoid throwing/catching exceptions then it should be done.
I was able to do it like this:
try {
number = page.select(".page").last().text();
if (number != null) {
pageFinalNumber = Integer.parseInt(number);
}
} catch (NullPointerException e) {
pageFinalNumber = 1;
}
Thanks for helping!
I keep getting bad request error when trying to use RestTemplate. I've tried both getForObject() and exchange() methods and neither did work, so am I doing something wrong ?
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("Accept", MediaType.APPLICATION_JSON.toString());
MultiValueMap<String, String> requestBody = new LinkedMultiValueMap<>();
requestBody.add("param1", "value1");
requestBody.add("param2", "true");
RestTemplate restTemplate = new RestTemplate();
return restTemplate.exchange(API_URI, HttpMethod.POST,
new HttpEntity<>(requestBody, headers), String.class);
stack trace:(hidded api names)

Can you try removing Accept header,as it is default json
headers.add("Accept", MediaType.APPLICATION_JSON.toString());
OR
try adding accept header as below
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
And check what is the response-type object you have mentioned as String.class,please crosscheck
Can you try changing as below
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
MultiValueMap<String, Object> requestBody = new LinkedMultiValueMap<>();
requestBody.add("param1", "value1");
requestBody.add("param2", true);Try this?

I am using Redis Database in my Java application (using Spring Boot).
To connect, get, put and delete my json from Redis Cluster I am using Lettuce open source library.
I have a RedisManager class that handlers connection to database and a RedisCache to effectively execute the commands of get, put and del.
RedisManager.java:
import com.lambdaworks.redis.RedisClient;
import com.lambdaworks.redis.RedisURI;
import com.lambdaworks.redis.cluster.ClusterClientOptions;
import com.lambdaworks.redis.cluster.RedisClusterClient;
import com.lambdaworks.redis.cluster.api.StatefulRedisClusterConnection;
import com.lambdaworks.redis.resource.ClientResources;
import com.lambdaworks.redis.resource.DefaultClientResources;
public class RedisManager{
private StatefulRedisClusterConnection<String, String> connection;
private boolean clusterMode
public RedisManager {
this.clusterMode = true;
connect(clusterMode);
}
private void connectToCluster(){
/**
* It simply gets my endpoint as a string
*/
String endpoint = PROPERTIES.getProperty(CLUSTER_ENDPOINT);
ClientResources res = DefaultClientResources.builder()
.ioThreadPoolSize(3)
.computationThreadPoolSize(3)
.build();
clusterClient = RedisClusterClient.create(res, RedisURI.create(endpoint, 6379));
try {
connection = clusterClient.connect();
} catch (Exception e) {
e.printStackTrace();
}
}
}
RedisCache:
import com.lambdaworks.redis.RedisCommandTimeoutException;
import com.lambdaworks.redis.RedisException;
import com.lambdaworks.redis.cluster.api.sync.RedisAdvancedClusterCommands;
public class RedisCache {
private RedisManager redisManager;
public RedisCache() {
this.redisManager = new RedisManager();
}
public String getAttribute(String hash, String key) {
String attribute = null;
try {
if (redisManager.isClusterMode()) {
RedisAdvancedClusterCommands<String, String> syncCommands = redisManager.getConnection().sync();
attribute = syncCommands.hget(hash, key);
} else {
attribute = redisManager.getRedis().hget(hash, key);
}
} catch (NullPointerException e) {
e.printStackTrace();
} finally {
redisManager.getConnection().close();
}
return attribute;
}
How I effectively use these classes:
RedisCache cacheService = new RedisCache();
String fund = null;
String hash = "myHash"
String key = "myKey"
try{
fund = cacheService.getAttribute(hash, key);
} catch (Exception e) {
e.printStackTrace();
}
So, IT WORKS FOR A SMALL NUMBER OF REQUESTS, but, when I stress my API, I receive this error:
2017-06-22 16:16:47.804 WARN 5 --- [nio-8080-exec-5] c.l.r.c.topology.ClusterTopologyRefresh : Cannot connect to RedisURI [host='myHostHere', port=6379]
