Watson Spring Boot

Deprecated builds

This project adds Spring Boot support for the Watson services.

This means that you can now "auto-wire" any of the Watson services into your Spring Boot application using the standard Spring autoconfiguration framework.

Usage

All you need to do is:

1. Add the Watson watson-spring-boot-starter dependency to your Spring Boot app:

   In your maven pom.xml

   <dependency>
     <groupId>com.ibm.watson.developer_cloud</groupId>
     <artifactId>watson-spring-boot-starter</artifactId>
     <version>2.3.6</version>
   </dependency>
   

   or in your gradle build.gradle, in the dependencies stanza, add

   compile 'com.ibm.watson.developer_cloud:watson-spring-boot-starter:2.3.6'
   

2. Add your Watson service(s) credentials and version info to your application properties file. The standard location for application properties is the src/main/resources/application.properties file, but your application might use a different location. The properties to add are:

• watson.<service>.url: The base URL for the service. This can be omitted if your service uses the default service url

• watson.<service>.username and watson.<service>.password OR watson.<service>.apiKey OR watson.<service>.iamApiKey: The credentials for accessing the service. The credentials can be omitted from the application properties file if they are supplied through the VCAP_SERVICES environment variable.

• watson.<service>.versionDate: Some Watson services use a versionDate parameter to indicate the service behavior expected by the application. For services that accept it, this is a required parameter and must be specified in the application properties.

  Both Eclipse and IntelliJ (Ultimate Edition) offer autocomplete support for Spring Boot application properties and should show these properties, along with their required type and Javadoc description, in the autocomplete menu.

3. Autowire the service into your application. Autowiring is the key mechanism of the Spring framework for injecting dependencies. It is accomplished by specifying the @Autowired annotation on the declaration for the service instance. Here's an example using the Watson Conversation service:

@Autowired
protected Conversation service;

The Spring framework takes care of the rest. Your application can now simply start using the service instance.
