IBM Bluemix - Spring Boot Elasticsearch Repositories demo

I decided to take the Elasticsearch repositories as part of the Spring Data project for a test drive. The Spring boot Elasticsearch repositories are described in the link below.

In this example I create a basic Spring Boot application using Elasticsearch, Web, Rest Repositories along with Thymeleaf / Bootstrap as the view pages. The code for this is on GitHub which also provides the "Deploy to Bluemix" button to deploy to your own instance of this application into your own Bluemix accout.

Like all Spring Data Repositories you can create an interface and be given basic CRUD operations to the Elastisearch DOCUMENT as shown below.


import java.util.List;

public interface EmployeeRepository extends ElasticsearchRepository<Employee, String>
    public List<Employee> findByFirstNameContaining(String firstName);


@Document(indexName = "employee", type = "employee", shards = 1, replicas = 0, refreshInterval = "-1")
public class Employee
    private String id;
    private String firstName;
    private String lastName;
    private String job;
    private int deptNo;

    public Employee()


If you don't have a IBM DevOps Jazzhub account the manifest.yml can be used if you clone the project, and compile it using maven with "mvn package". Be sure to alter the application name / host to be a unique name within Bluemix.

IBM Bluemix - Specify only Liberty buildpack features you require

I am more often then not using spring boot applications on IBM Bluemix and most of what I need is packaged with the application from JPA or JDBC, drivers, Rest etc. Of course with IBM Bluemix we can specify which build pack we wish to use but by default for java applications LIberty is used.

When a stand-alone application is deployed, a default Liberty configuration is provided for the application. The default configuration enables the following Liberty features:

  • beanValidation-1.1
  • cdi-1.2
  • ejbLite-3.2
  • el-3.0
  • jaxrs-2.0
  • jdbc-4.1
  • jndi-1.0
  • jpa-2.1
  • jsf-2.2
  • jsonp-1.0
  • jsp-2.3
  • managedBeans-1.0
  • servlet-3.1
  • websocket-1.1
  • icap:managementConnector-1.0
  • appstate-1.0
Here is how I strip out some of what isn't required in my Liberty runtime container to a bare minimal of what I need.

IBM Bluemix - Triggerring backing service creation from "Deploy to Bluemix" button

I recently posted about the "Deploy to Bluemix" button which will automatically deploy an application into IBM Bluemix from a single click.

If the application requires backing services they can automatically be created using the"declared-services" tag as shown below. Declared services are a manifest extension, which creates or looks for the required or optional services that are expected to be set up before the app is deployed, such as a data cache service. You can find a list of the eligible Bluemix services, labels, and plans by using the CF Command Line Interface and running cf marketplace


    label: rediscloud
    plan: 30mb
 - name: pas-sbsessions
   memory: 512M
   instances: 2
   path: ./target/SpringBootHTTPSession-0.0.1-SNAPSHOT.jar
   host: pas-sbsessions
   buildpack: java_buildpack
    - redis-session

Note: Declared services is an IBM extension of the standard Cloud Foundry manifest format. This extension might be revised in a future release as the feature evolves and improves.
