Static handlers

Comment

In our examples above, the SpringLambdaContainerHandler is declared as a static variable in the RequestStreamHandler implementation and initialized in a static block. This means Lambda executes the code as it starts the JVM, giving you better performance out of the gate.

private static SpringLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
static {
    try {
        handler = SpringLambdaContainerHandler.getAwsProxyHandler(PetStoreSpringAppConfig.class);
    } catch (ContainerInitializationException e) {
        // if we fail here. We re-throw the exception to force another cold start
        e.printStackTrace();
        throw new RuntimeException("Could not initialize Spring framework", e);
    }
}
