Package and run a Java class as an AWS Lambda function.
First, prepare your Java class:
- Ensure your class implements the
RequestHandler<Input, Output>
interface from thecom.amazonaws:aws-lambda-java-core
library. This defines the handler method that processes events. - Include any necessary dependencies in your
pom.xml
file (if you’re using Maven):<dependency> <groupId>com.amazonaws</groupId> <artifactId>aws-lambda-java-core</artifactId> <version>1.2.x</version> </dependency>
Be sure to replace 1.2.x
with the latest compatible version of the aws-lambda-java-core
library.
Then, package your code:
Create a JAR file containing your compiled Java class and all its dependencies. You can use a tool such as Maven or a simple command such as jar cvf myLambdaFunction.jar target/classes/*.class
(assuming compiled...
