Setting Up SAP Leonardo Environment
- Ensure you have a valid SAP Cloud Platform account with access to SAP Leonardo microservices.
- Install the SAP Cloud SDK to enable integration with Leonardo services. This can be downloaded from the SAP Developer Center.
- Configure your SAP Cloud SDK by setting up the environment variables correctly to connect with your SAP Cloud Platform account.
Configuring IntelliJ IDEA
- Download and install IntelliJ IDEA from the JetBrains website if you have not already done so.
- Set up a new Java or Spring Boot project, ensuring that the Java SDK is correctly configured under Project Structure.
- Install the SAP Cloud Platform Tools for Java (Eclipse version) within IntelliJ by using the "Eclipse" plugin compatibility.
Adding SAP Leonardo SDK
- Open your IntelliJ project and navigate to the `pom.xml` file if you're using Maven, or `build.gradle` if you're using Gradle.
- Add the necessary dependencies for SAP Cloud SDK in the dependencies block of your build file.
<dependency>
<groupId>com.sap.cloud.sdk.cloudplatform</groupId>
<artifactId>cloudsdk-core</artifactId>
<version>[SAP_SDK_VERSION]</version>
</dependency>
dependencies {
implementation 'com.sap.cloud.sdk.cloudplatform:cloudsdk-core:[SAP_SDK_VERSION]'
}
Connecting to SAP Leonardo Services
- Create a service key in your SAP Cloud Platform cockpit for your Leonardo service to obtain credentials and necessary connection details.
- Securely store the service key details, especially the client ID, client secret, and URL, which will be used for authentication and connecting to the microservices.
Implementing SAP Leonardo Microservices
- Use the obtained service key details to configure authentication in your project. You can do this by setting environment variables or directly coding the client credential flow.
- Create a Java class in your project that will consume SAP Leonardo services. Use SAP Cloud SDK libraries for simplified OAuth handling and API calls.
import com.sap.cloud.sdk.cloudplatform.connectivity.HttpDestination;
import com.sap.cloud.sdk.cloudplatform.connectivity.DestinationAccessor;
HttpDestination destination = DestinationAccessor.getHttpDestination("YOUR_DESTINATION_NAME");
// Creating a request to Leonardo Service
response = destination.execute(client -> client
.target(serviceUrl)
.request(MediaType.APPLICATION_JSON)
.header("Authorization", "Bearer " + serviceKey.getAccessToken())
.get());
Testing the Integration
- Ensure proper logging is in place to capture requests and responses for debugging purposes.
- Run your IntelliJ project and verify that requests to SAP Leonardo are successful by checking the response data.
- Utilize IntelliJ’s debugging tools to step through your integration logic and resolve any issues or modify implementations as necessary.
Deploying and Monitoring
- Once tested, deploy the application to your preferred environment, whether it is on-premises or in the cloud.
- Monitor your application for performance and connectivity issues using monitoring tools provided by SAP Cloud Platform and IntelliJ IDEA.
