Spring Boot with Maven
How to use Hanzo KMS to inject environment variables into Java Spring Boot
Prerequisites:
- Set up and add your environment variables to Hanzo KMS Cloud
Initialize Hanzo KMS
In order for Hanzo KMS to know which secrets to fetch, you'll need to first initialize Hanzo KMS at the root of your project.
# navigate to the root of your of your project
cd /path/to/project
# then initialize Hanzo KMS
kms initStart your application with Maven wrapper
To pass in Hanzo KMS secrets into your application, we will utilize the KMS CLI to inject the secrets into the Maven wrapper executable, which is used to launch your application. The Maven wrapper executable should already be present in the root directory of your project.
kms run -- ./mvnw spring-boot:run --quietAccessing injected secrets
...
import org.springframework.core.env.Environment;
@SpringBootApplication
public class DemoApplication {
@Autowired
private Environment env;
@Bean
public void someMethod() {
System.out.println(env.getProperty("SOME_SECRET_NAME"));
};
}Debugging with secrets
During the process of debugging your code, it may be necessary to have certain environment variables available. To inject these variables for the purpose of debugging, please follow the instructions provided below. Note that these instructions are currently only available for IntelliJ.
Step 1: On the main tool bar, choose Edit Configuration
Step 2: Click the plus icon
Step 3: Select Shell Script
Step 4: Choose Script Text and then paste in the command below.
kms run -- ./mvnw spring-boot:run -Dspring-boot.run.jvmArguments="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=*:5005"Step 5: When you need to run a block of code in debug mode, select the Hanzo KMS script
