call controller method using jquery

I am trying to fetch an article from the db using jquery code
this is the jquery function
function searchArticle(codeArticle){
if(codeArticle){
//alert(codeArticle);
var detailHtml ="";
$.getJSON("detailArticle",
{
codeArticle: codeArticle,
ajax:true
},
function(data){
if(data){
detailHtml+= "<tr>"+
"<td>"+data[0].article.codeArticle+"</td>"+
"<td>1</td>"+
"<td>"+data[0].prixUnitaireTTC+"</td>"+
"<td>0</td>"+
"</tr>";
$("#detailNouvelleCommande").append(detailHtml);
}else{
alert("article not found");
}
});
}
}
and this is my controller method
#RequestMapping(value = "/detailArticle")
#ResponseBody
public Article getArticleByCode(String codeArticle){
if(codeArticle == null){
return null;
}
Article article = articleService.findOne("codeArticle", codeArticle);
if(article == null){
return null;
}
return article;
}
the method selects the article from database correctly however while returning it I receive the following eror:
java.lang.IllegalArgumentException: No converter found for return value of type: class com.stock.mvc.entity.Article

How to fix the error org.springframework.web.client.HttpClientErrorException: 400 null, when using RestTemplate to access Microservice

In my java code, I am trying to access a microservice using RestTemplate as the following:
headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
entity = new HttpEntity<BigDecimal>(c.getDocumentId(),headers);
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8082/document-external-id", HttpMethod.POST, entity, String.class);
String externalId= response.getBody();
On the server side, I have this:
#RequestMapping(value="/document-external-id", method=RequestMethod.POST)
String getExternalDocumentId(#RequestBody BigDecimal documentId)
{
System.out.println("Documents External Id Microservice called.....Params are:"+documentId);
Documents document =documentsService.findDocumentById(documentId);//invoke the method to get the document
System.out.println("Documents External Id microservice is DONE!.......................................Returning value:"+document.getExternalDocumentId());
return document.getExternalDocumentId();
}
When I run my code, here's the output with the error on the client side, which occurs at this line:
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8082/document-external-id", HttpMethod.POST, entity, String.class);
The error is:

On the server side, I have the following output with a Warning message:

How to fix the error? Thanks.

It turned out that the value null of some document ids causes the problem. Perhaps, because #RequestBody does not accept a null value.
Here's the update to fix the problem:
if(documentId!=null)
{
headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
entity = new HttpEntity<BigDecimal>(documentId,headers);
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8082/document-name", HttpMethod.POST, entity, String.class);
documentName= response.getBody();
}

Have you tried with an annotation like:
#PostMapping(value = "/document-external-id", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public String getExternalDocumentId(#RequestBody BigDecimal documentId){
System.out.println("Documents External Id Microservice called.....Params are:"+documentId);
Documents document =documentsService.findDocumentById(documentId);//invoke the method to get the document
System.out.println("Documents External Id microservice is DONE!.......................................Returning value:"+document.getExternalDocumentId());
return document.getExternalDocumentId();
}

Retrofit - Spring Image upload

I have a problem in uploading file to server(Spring Boot) from Android-retrofit.
this is my code in Spring Boot.
#RestController
#RequestMapping("beongae/api/{version}/profile")
public class ProfileController {
#RequestMapping(value = "/upload/{name}", method = RequestMethod.POST)
public ApiMessasge uploadBasic(#PathVariable("name") String name,
#RequestPart("file") MultipartFile data) throws IOException {
ApiMessasge apiMessasge = new ApiMessasge();
System.out.println("start upload !!");
if (!data.isEmpty()) {
try {
byte[] bytes = data.getBytes();
BufferedOutputStream stream = new BufferedOutputStream(
new FileOutputStream("./profilepictures/" + new File(name + ".png"))
);
stream.write(bytes);
stream.close();
apiMessasge.setCode(1);
} catch (Exception e) {
System.out.println("Exception : " + e.getMessage());
for (int i = 0; i < e.getStackTrace().length; i++) {
System.out.println(e.getStackTrace()[i].toString());
}
apiMessasge.setCode(-1);
}
}
return apiMessasge;
}
}
This is in Android
Uri resultUri = result.getUri();
File file = new File(resultUri.getPath());
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("file", file.getName(), requestFile);
And this is in APiService.class
#Multipart
#Headers("Content-Type:application/json")
#POST("/beongae/api/{version}/profile/upload/{name}")
Call<ApiMessasge> upload(#Path("version") int version, #Path("name") String fileName
, #Part MultipartBody.Part file);
And This is the error message in Spring Boot

Spring RESTful, error returning JSON

i'm encountering an error while producing JSON from DAO, here is my code
Controller
#RequestMapping(value="/findAdpId/", method=RequestMethod.POST , consumes = "application/json", produces = "application/json")
public #ResponseBody AllCustomerHist findAdpId(#RequestBody AllCustomerHist customer){
String customerId = customer.getCustomerId();
String srctable = customer.getSrctable();
System.out.println("customer ID = "+customerId);
System.out.println("srctable = "+srctable);
List<AllCustomerHist> adpcust = allCustomerHistService.findAdpId(customerId, srctable);
return (AllCustomerHist) adpcust;
}
DAO Class
#SuppressWarnings("unchecked")
public List<AllCustomerHist> findAdpId(String customerId, String srctable) {
// TODO Auto-generated method stub
Criteria criteria = getSession().createCriteria(AllCustomerHist.class)
.setProjection(Projections.projectionList()
.add(Projections.property("adpId"), "adpId"))
.add(Restrictions.eq("customerId", customerId))
.add(Restrictions.eq("srctable", srctable));
return (List<AllCustomerHist>)criteria.list();
}
what i want is, when retrieving JSON like
{
"customerId":"11",
"srctable":"transaction"

my DAO class will produce

How to use matchQuery in java api elasticsearch client

I m tring to use the matchQuery of java api elasticsearch but the curl return 0 documents.
Here my code:
webservice:
#RequestMapping(path = "/blog/search/{text}", method = RequestMethod.GET)
public List<PostDocument> search(
#PathVariable String text,
#RequestParam("from") int from,
#RequestParam("size") int size
) {
return this.searchService.search(text, from, size);
}
searchService.search:
public List<PostDocument> search(String fulltextQuery, int from, int size) {
SearchRequestBuilder searchRequestBuilder = this.client.prepareSearch(indexConfig.getIndexAlias());
System.out.println(fulltextQuery);
searchRequestBuilder.setQuery(this.createQuery(fulltextQuery));
searchRequestBuilder.setFrom(from);
searchRequestBuilder.setSize(size);
SearchResponse response = searchRequestBuilder.get();
return this.parseResponse(response);
}
private QueryBuilder createQuery(String fulltextQuery) {
return QueryBuilders.matchQuery("title",fulltextQuery);
}
my curl
using postman
localhost:8080/blog/search/post?from=1&size=10
result:

Someone help me please, i have an error in my code or in my curl.
I am sure that i have data in my elasticsearch

Here my code: parseResponse2
private List<PostDocument> parseResponse2(SearchResponse response) {
List<PostDocument> docs = new ArrayList<PostDocument>();
SearchHit[] hits = response.getHits().getHits();
for(SearchHit hit: hits) {
Post post = new Post(hit.sourceAsMap().get("title").toString(), hit.sourceAsMap().get("content").toString());
post.setId(Long.parseLong(hit.sourceAsMap().get("id").toString()));
docs.add(new PostDocument(hit.index(), post));
}
return docs;
}
Regards

The problem is that you have one document, and from should start from 0 but you input 1 instead.
Try this URL and it should work:
localhost:8080/blog/search/post?from=0&size=10
^

change this

try with localhost:8080/blog/post/_search/?from=1&size=10
Try with hardcoding index name and type name
JAVA API code :-
QueryBuilder searchQuery = QueryBuilders.matchQuery("title", "");
SearchRequestBuilder countRequestBuilder = esClient.prepareSearch("INDEXNAME").setTypes("TYPE").setQuery(searchQuery);
SearchResponse response = countRequestBuilder.execute().actionGet("ACTION_TIMEOUT"), TimeUnit.SECONDS);
SearchHit[] seacrhHits = response.getHits().getHits();
