IBM Bluemix demo using IBM Watson Personality Insights service

The IBM Watson Personality Insights service uses linguistic analysis to extract cognitive and social characteristics from input text such as email, text messages, tweets, forum posts, and more. By deriving cognitive and social preferences, the service helps users to understand, connect to, and communicate with other people on a more personalized level.

Adding MySQL driver to Spring Boot CLI Groovy Demo

I previously showed how you can use the Spring Boot CLI to create a simple Restful Application saying Hello World as shown in the link below using Groovy.

http://theblasfrompas.blogspot.com.au/2015/02/spring-boot-hello-world-from-command.html

If you wanted to extend that demo to include additional dependencies JAR file such as MySQL driver jar file we would do the following

1. You can add extensions to the CLI using the install command as shown below to add MySQL driver. This is installed in the LIB folder of the Spring Boot CLI location directory

> spring install mysql:mysql-connector-java:5.1.34

2. Package the application into a JAR which now includes the MySQL driver JAR file to enable you to connect to a MySQL instance from your application. You will need to write the code to do that , BUT now the JAR file is packaged in the JAR created to enable you to do that.

> spring jar -cp /usr/local/Cellar/springboot/1.2.1.RELEASE/lib/mysql-connector-java-5.1.34.jar hello.jar hello.groovy

Note: If you find that you reach the limit of the CLI tool, you will probably want to look at converting your application to full Gradle or Maven built “groovy project”

Reading VCAP_SERVICES Postgresql service credentials within Bluemix

The following shows how you can easily read the VCAP_SERVICES postgresql credentials within your Java Code using the maven repo. This assumes your using the ElephantSQL Postgresql service. A single connection won't be ideal but for demo purposes might just be all you need.

1. First add the maven dependency as follows. This will add WebSphere Application Server Liberty Profile to your project

  
<dependency>
        <groupId>com.ibm.tools.target</groupId>
        <artifactId>was-liberty</artifactId>
        <version>LATEST</version>
        <type>pom</type>
        <scope>provided</scope>
</dependency>

2. In your code , something as follows gets you the Connection details to make a JDBC connection withinyou java code.

  
private static Connection getConnection() throws Exception 
{
 Map<String, String> env = System.getenv();
 
 if (env.containsKey("VCAP_SERVICES")) {

  JSONObject vcap = (JSONObject) JSON.parse(env.get("VCAP_SERVICES"));
  JSONObject service = null;
  
  // We don't know exactly what the service is called,
  // but it will contain "elephantsql"
  for (Object key : vcap.keySet()) {
   String keyStr = (String) key;
   if (keyStr.toLowerCase().contains("elephantsql")) {
    service = (JSONObject) ((JSONArray) vcap.get(keyStr)).get(0);
    break;
   }
  }
  
  if (service != null) {
   JSONObject creds = (JSONObject) service.get("credentials");
   URI uri = URI.create((String) creds.get("uri"));
   String url = "jdbc:postgresql://" + uri.getHost() + ":" +
            uri.getPort() +
            uri.getPath();
   String username = uri.getUserInfo().split(":")[0];
   String password = uri.getUserInfo().split(":")[1];
   return DriverManager.getConnection(url, username, password);
  }
 }
 
 throw new Exception("No ElephantSQL service URL found. Make sure you " +
      "have bound the correct services to your app.");
}
