me.ccampo.spring.aws.lambda

Class SpringRequestHandler<I,O>

java.lang.Object

me.ccampo.spring.aws.lambda.SpringRequestHandler<I,O>

Type Parameters:

I - The input type parameter. NOTE: this type must match the input type parameter of your RequestHandler bean.

O - The output type parameter. NOTE: this type must match the input type parameter of your RequestHandler bean.

All Implemented Interfaces:

com.amazonaws.services.lambda.runtime.RequestHandler<I,O>, ApplicationContextProvider

Direct Known Subclasses:

SpringVoidRequestHandler

public abstract class SpringRequestHandler<I,O>
extends java.lang.Object
implements com.amazonaws.services.lambda.runtime.RequestHandler<I,O>, ApplicationContextProvider

Central class to extend to provide Spring support for your AWS Lambda applications. The key to using this class is to implement the ApplicationContextProvider.getApplicationContext() method and supply a valid ApplicationContext instance. Your child class that extends this class will be the entry point (handler) to your AWS Lambda function.

The handleRequest(Object, Context) method is left virtual so it can be overridden, but the default implementation should work for most use cases. It simply grabs a bean of type RequestHandler and calls that class's RequestHandler.handleRequest(Object, Context) method. In this sense, this class is just a wrapper around your implementation of RequestHandler, but allows your implementation to take advantage of Spring's core features (dependency injection, etc).
