How to properly implement adding a new record into Elasticsearch using Spring Boot? - elasticsearch

Question

Getting started with Spring Boot / Spring Data / Elasticsearch application.
ES -> 6.1
Have a simple repository:
public interface BusinessMetadataRepository extends ElasticsearchRepository<BusinessMetadata, Long> {
List<BusinessMetadata> findByName(String name);
List<BusinessMetadata> findById(Long id);
}
And a Business Object:
import org.springframework.data.elasticsearch.annotations.Document;
#Document(indexName = "bsn", type = "mtd", shards = 1)
public class BusinessMetadata {
private Long id;
private String name;
public Long getId() {return id;}
public void setId(Long id) {this.id = id;}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public BusinessMetadata(Long id, String name) {
this.id = id;
this.name = name;
}
public BusinessMetadata() {
}
}
Elastic Configuration:
#Configuration
#EnableElasticsearchRepositories(basePackages = "com.discover.harmony.elastic.repository")
public class ElasticConfiguration {
#Bean
public NodeBuilder nodeBuilder() {
return new NodeBuilder();
}
#Bean
public ElasticsearchOperations elasticsearchTemplate() throws IOException {
File tmpDir = File.createTempFile("elastic", Long.toString(System.nanoTime()));
System.out.println("Temp directory: " + tmpDir.getAbsolutePath());
Settings.Builder elasticsearchSettings =
Settings.settingsBuilder()
.put("http.enabled", "true") // 1
.put("index.number_of_shards", "1")
.put("path.data", new File(tmpDir, "data").getAbsolutePath()) // 2
.put("path.logs", new File(tmpDir, "logs").getAbsolutePath()) // 2
.put("path.work", new File(tmpDir, "work").getAbsolutePath()) // 2
.put("path.home", tmpDir); // 3
return new ElasticsearchTemplate(nodeBuilder()
.local(true)
.settings(elasticsearchSettings.build())
.node()
.client());
}
}
My Rest Controller for doing search works fine:
#RestController
#RequestMapping("/rest/search")
public class SearchResource {
#Autowired
BusinessMetadataRepository businessMetadataRepository;
#GetMapping(value = "/name/{text}")
public List<BusinessMetadata> searchName(#PathVariable final String text) {
return businessMetadataRepository.findByName(text);
}
#GetMapping(value = "/all")
public List<BusinessMetadata> searchAll() {
List<BusinessMetadata> businessMetadataList = new ArrayList<>();
Iterable<BusinessMetadata> businessMetadata = businessMetadataRepository.findAll();
businessMetadata.forEach(businessMetadataList::add);
return businessMetadataList;
}
}
My Rest Controller for doing save:
#RestController
#RequestMapping("/rest/save")
public class SaveResource {
#Autowired
BusinessMetadataRepository businessMetadataRepository;
#GetMapping(value = "/name/{text}")
public void Save(String text) {
businessMetadataRepository.save(new BusinessMetadata((long)99, text));
}
}
When I test the save using Postman, I get this error:
{
"timestamp": 1514325625996,
"status": 405,
"error": "Method Not Allowed",
"exception": "org.springframework.web.HttpRequestMethodNotSupportedException",
"message": "Request method 'POST' not supported",
"path": "/rest/save/name/new-1"
}
What changes do I need to make in order to properly configure this project to support inserting new documents?

Answer 1

Based on the comment from AntJavaDev, I have modified my controller in the following way:
#RestController
#RequestMapping("/rest/save")
public class SaveResource {
#Autowired
BusinessMetadataRepository businessMetadataRepository;
#PostMapping("/name/{text}")
public void Save(#PathVariable String text) {
BusinessMetadata mtd = businessMetadataRepository.save(new BusinessMetadata(text));
}
}
The 2 key changes are: replace #GetMapping with #PostMapping, and include #PathVariable as a parameter qualifier.
Now it works as expected
