Class JerseyLambdaContainerHandler<RequestType,ResponseType>

java.lang.Object

com.amazonaws.serverless.proxy.internal.LambdaContainerHandler<RequestType,ResponseType,org.glassfish.jersey.server.ContainerRequest,com.amazonaws.serverless.proxy.jersey.JerseyResponseWriter>

com.amazonaws.serverless.proxy.jersey.JerseyLambdaContainerHandler<RequestType,ResponseType>

Type Parameters:

RequestType - The type for the incoming Lambda event

ResponseType - The type for Lambda's return value

All Implemented Interfaces:

org.glassfish.jersey.server.spi.Container

public class JerseyLambdaContainerHandler<RequestType,ResponseType>
extends LambdaContainerHandler<RequestType,ResponseType,org.glassfish.jersey.server.ContainerRequest,com.amazonaws.serverless.proxy.jersey.JerseyResponseWriter>
implements org.glassfish.jersey.server.spi.Container

Jersey-specific implementation of the LambdaContainerHandler interface. Given a Jax-Rs application starts Jersey's ApplicationHandler and proxies requests and responses using the RequestReader and ResponseWriter objects. The reader and writer objects are inherited from the BaseLambdaContainerHandler object.

 
   public class LambdaHandler implements RequestHandler<AwsProxyRequest, AwsProxyResponse> {
     private ResourceConfig jerseyApplication = new ResourceConfig().packages("your.app.package");
     private JerseyLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> container = JerseyLambdaContainerHandler.getAwsProxyHandler(jerseyApplication);

     public AwsProxyResponse handleRequest(AwsProxyRequest awsProxyRequest, Context context) {
       return container.proxy(awsProxyRequest, context);
     }
   }

JerseyLambdaContainerHandler

public JerseyLambdaContainerHandler(RequestReader<RequestType,org.glassfish.jersey.server.ContainerRequest> requestReader,
                                    ResponseWriter<com.amazonaws.serverless.proxy.jersey.JerseyResponseWriter,ResponseType> responseWriter,
                                    SecurityContextWriter<RequestType> securityContextWriter,
                                    ExceptionHandler<ResponseType> exceptionHandler,
                                    javax.ws.rs.core.Application jaxRsApplication)

Private constructor for a LambdaContainer. Sets the application object, sets the ApplicationHandler, and initializes the application using the onStartup method.

Parameters:

jaxRsApplication - A Jersey application instance.

Method Detail

getAwsProxyHandler

public static JerseyLambdaContainerHandler<AwsProxyRequest,AwsProxyResponse> getAwsProxyHandler(javax.ws.rs.core.Application jaxRsApplication)

Returns an initialized JerseyLambdaContainerHandler that includes RequestReader and ResponseWriter objects for the AwsProxyRequest and AwsProxyResponse objects.

Parameters:

jaxRsApplication - A configured Jax-Rs application object. For Jersey apps this can be the default ResourceConfig object

Returns:

A JerseyLambdaContainerHandler object

getConfiguration

public org.glassfish.jersey.server.ResourceConfig getConfiguration()

Gets the configuration currently set in the internal ApplicationHandler

Specified by:

getConfiguration in interface org.glassfish.jersey.server.spi.Container

Returns:

The Jersey's ResourceConfig object currently running in the container

getApplicationHandler

public org.glassfish.jersey.server.ApplicationHandler getApplicationHandler()

The instantiated ApplicationHandler object used by this container

Specified by:

getApplicationHandler in interface org.glassfish.jersey.server.spi.Container

Returns:

Jersey's ApplicationHander object

reload

public void reload()

Shuts down and restarts the application handler in the current container. The ApplicationHandler object is re-initialized with the Application object initially set in the LambdaContainer.getInstance() call.

Specified by:

reload in interface org.glassfish.jersey.server.spi.Container

reload

public void reload(org.glassfish.jersey.server.ResourceConfig resourceConfig)

Restarts the application handler and configures a different Application object. The new application resets the one currently configured in the container.

Specified by:

reload in interface org.glassfish.jersey.server.spi.Container

Parameters:

resourceConfig - An initialized Application

getContainerResponse

protected com.amazonaws.serverless.proxy.jersey.JerseyResponseWriter getContainerResponse(java.util.concurrent.CountDownLatch latch)

Specified by:

getContainerResponse in class LambdaContainerHandler<RequestType,ResponseType,org.glassfish.jersey.server.ContainerRequest,com.amazonaws.serverless.proxy.jersey.JerseyResponseWriter>

handleRequest

protected void handleRequest(org.glassfish.jersey.server.ContainerRequest containerRequest,
                             com.amazonaws.serverless.proxy.jersey.JerseyResponseWriter jerseyResponseWriter,
                             com.amazonaws.services.lambda.runtime.Context lambdaContext)

Specified by:

handleRequest in class LambdaContainerHandler<RequestType,ResponseType,org.glassfish.jersey.server.ContainerRequest,com.amazonaws.serverless.proxy.jersey.JerseyResponseWriter>
