Configuring Spring-Cloud dataflow server

Spring Cloud data flow is the new job/stream orchestrator post Spring decomissioned it’s suport for Spring Batch. It can take tasks/streams and execute them in form of microservices, which looks really cool.

The configuration is pretty straightforward and simple-

In maven pom.xml, please make following entries-

In properties-

<spring-cloud-dataflow.version>1.7.1.RELEASE</spring-cloud-dataflow.version>

In the dependencies section add the following dependencies-

<dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-dataflow-server-local</artifactId>
      <version>${spring-cloud-dataflow.version}</version>
   </dependency>
   <dependency>
     <groupId>mysql</groupId>
     <artifactId>mysql-connector-java</artifactId>
    </dependency>
</dependencies>

In the Spring Boot main application class we just need two annotations-

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.dataflow.server.EnableDataFlowServer;
@SpringBootApplication
@EnableDataFlowServer
/**
* Application which acts as an orchestrator for running the
* ETL tasks and streams.
* @author dhruv
*
*/
public class DemoAppBatchApplication
{
   public static void main(String[] args) {
     SpringApplication.run(DemoAppBatchApplication.class, args);
    }
}

In application.properties make the following datasource entries-

server.port=8081
spring.datasource.url= jdbc:mysql://localhost:3306/demoapp_batch
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=none

Hit the below url

http://localhost:8081/dashboard/#/apps

and cloud data flow should be up and running.

Fairly simple !!
