How to save single document to Elasticsearch index? - elasticsearch

Question

I am trying to put into my ES index mapping an exemplary two fielded book class entity like below. As a result I ONLY get the index and mapping created but the JSON is not put in the place.
#RunWith(SpringJUnit4ClassRunner.class)
#SpringBootTest
public class ElasticSearchTransactionsApplicationTests {
#Autowired
private BookRepository bookRepository;
#Autowired
private ElasticsearchTemplate elasticsearchTemplate;
#Test
public void shouldCreateSingleBookEntityWitRepository(){
elasticsearchTemplate.deleteIndex(Book.class);
elasticsearchTemplate.createIndex(Book.class);
elasticsearchTemplate.putMapping(Book.class);
elasticsearchTemplate.refresh(Book.class);
//given
IndexQuery queryCreatingBookEntity = new BookBuilder("1").setTitle("BBB").buildBookIndex();
//when
elasticsearchTemplate.index(queryCreatingBookEntity);
elasticsearchTemplate.refresh(Book.class);
//then
assertThat(bookRepository.findOne("1"), is(notNullValue()));
}
While it creates the index and mapping BUT it does not put the Book inside it - why?
EDIT
Test fils like this:
java.lang.AssertionError:
Expected: is not null
but: was null
Expected :is not null
Actual :null
<Click to see difference>
at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20)
When I GET _all/_mapping
{
"bookshop": {
"mappings": {
"book": {
"properties": {
"bid": {
"type": "string"
},
"title": {
"type": "string"
}
}
}
}
}
}
Also I check my index and mapping created but when I try to get the content:
GET /bookshop/book/1
{
"_index": "bookshop",
"_type": "book",
"_id": "1",
"found": false
}
So I get found false. So no book added.

Book.java
#Data
#Document(indexName = "bookshop", type = "book", shards = 1, replicas = 0, refreshInterval = "-1")
public class Book {
#Id
private String bID;
#Field(type = FieldType.String, store = true)
private String title;
}
I have also put my book.java with lombok generated #Data and extended #Document content

My code is almost similar to yours. I've used this when I was playing with Spring Data Elasticsearch ages ago. I've just updated the version to 1.4.0.RELEASE The test is passing.
The pom.xml

The Book.class
package com.demo.model;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.annotation.Id;
/**
* Holds the details of book.
*/
#Document(indexName = "book")
public class Book {
#Id
private String bookId;
private String title;
public String getBookId() {
return bookId;
}
public void setBookId(String bookId) {
this.bookId = bookId;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
The Repository
package com.demo.search.repository;
import com.demo.model.Book;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
/**
* Holds the Elasticsearch CRUD operations for {#link Book} entity.
*/
public interface BookSearchRepository extends ElasticsearchRepository<Book, String> {
}
And finally, the test.
package com.demo.search.repository;
import com.demo.model.Book;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.CoreMatchers.notNullValue;
import static org.junit.Assert.assertThat;
/**
* Test things on {#link BookSearchRepository}
*/
#RunWith(SpringJUnit4ClassRunner.class)
#SpringBootTest
public class BookSearchRepositoryTest {
#Autowired
private BookSearchRepository bookRepository;
#Autowired
private ElasticsearchTemplate elasticsearchTemplate;
#Before
public void before() {
elasticsearchTemplate.deleteIndex(Book.class);
elasticsearchTemplate.createIndex(Book.class);
elasticsearchTemplate.putMapping(Book.class);
elasticsearchTemplate.refresh(Book.class);
}
#Test
public void shouldSaveBook(){
Book book = new Book();
book.setBookId("1");
book.setTitle("Learning Scala");
Book indexedBook = bookRepository.save(book);
assertThat(indexedBook, is(notNullValue()));
assertThat(indexedBook.getBookId(), is(book.getBookId()));
assertThat(bookRepository.findOne("1"), is(notNullValue()));
}
}
