-This project provides an adapter layer for a Spring Cloud Function application onto AWS Lambda. You can write an app with a single `@Bean` of type `Function`, `Consumer` or `Supplier` and it will be deployable in AWS if you get the JAR file laid out right. The best way to make it work is to include `spring-cloud-function-context` as a dependency, but not the higher level adapters (e.g. `spring-cloud-function-web` or `spring-cloud-function-stream`).
+This project provides an adapter layer for a Spring Cloud Function application onto AWS Lambda. You can write an app with a single `@Bean` of type `Function`, `Consumer` or `Supplier` and it will be deployable in AWS if you get the JAR file laid out right. The best way to make it work is to include `spring-cloud-function-context` as a dependency, but not the higher level adapters (e.g. `spring-cloud-function-stream`).
 
 The adapter has a couple of generic request handlers that you can use. The most generic is `SpringBootStreamHandler`, which uses a Jackson `ObjectMapper` provided by Spring Boot to serialize and deserialize the objects in the function. There is also a `SpringBootRequestHandler` which you can extend, and provide the input and output types as type parameters (enabling AWS to inspect the class and do the JSON conversions itself).

+A Spring Cloud Stream binder for a Servlet container using Spring MVC.
+
+## Usage
+
+Add this jar to the classpath of a Spring Cloud Stream application as the only binder implementation. Endpoints are exposed at
+
+| Method    | Path                               | Description                |
+|-----------|------------------------------------|----------------------------|
+| GET       | `/stream/{channel}/{route}`        | If the channel is an `@Output` returns a list of the payloads of all messages sent to the channel with a routing key equal to `{route}`. |
+| GET       | `/stream/{channel}/{route}/{body}` | If the channel is an `@Input` sends the last segment of the path (the `{body}`) as a payload to the `{route}`. If the channel is not an input, it's an error (404). |
+| POST      | `/stream/{channel}/{route}`        | Accepts a single value or a list of payloads and sends them to the `@Input` called `{channel}` with routing key header equal to `{route}`.|
+
+The result of the POST depends on whether an `@Output` is linked to the `@Input`. By default a link is made if the user has `@EnableBinding` with an interface having precisely one `@Output` and one `@Input` (e.g. using `Processor` from Spring Cloud Stream).  In the case that there is no linked `@Output`, the return value from the POST is a 202 (Accepted) and a mirror of the input. If an `@Output` is linked, then the contents of the output channel are returned with a 200 status (OK).
+
+The routing key is sent via a message header named `stream_routekey`. It is a plain string, and can be multiple URI segments (i.e. contain "/"). It will show up in HTTP response headers if present. Message headers can be sent in a POST request using HTTP headers (as well as the special case of the route key being part of the path).
+
+Both the channel and route are optional, but can be used to disambiguate if necessary. So for example:
+
+| Method    | Path                     | Description                |
+|-----------|--------------------------|----------------------------|
+| GET       | `/stream`                | Defaults the channel name to `output` (or to the name of the `@Output` if there is only one). Messages sent with no routing key are delivered. |
+| GET       | `/stream/{channel}`      | Uses and explicit channel name but an empty routing key. If the channel is not a registered output, then it will be interpreted as a route  (see below). |
+| GET       | `/stream/{route}/{body}` | Equivalent to `GET /stream/input/{route}/{body}` if there is a unique input channel. |
+| GET       | `/stream/{route}`        | If the channel is missing (i.e. the first path segment is not a registered output or input), then it will be interpreted as a route. Equivalent to `GET /stream/output/{route}` if there is a unique output channel. |
+| POST      | `/stream/{route}`        | As long as the first segment of the route is not an input channel name, this defaults the channel to `input` (or to the name of the `@Input` if it is unique).|
+| POST      | `/stream`                | Defaults the channel to `input` (or to the name of the `@Input` if it is unique). The routing key is empty.|
+
+
+Note that with a GET, if the channel is not a registered output, then it will be interpreted as a route. So if there is a default input channel, then the path will be transformed into `{route}/{body}` (agin with route optional, if there is only one path segment) and sent to the input channel.
+
+The result of a GET is a moving time window by default (the last 10 seconds of data are buffered). Clients can request an infinite stream of data using `GET` with `Accept: text/event-stream` (or a compatible media type).
+
+Configuration properties (in addition to the ones provided by Spring Cloud Stream for bindings and channel names, etc.):
+
+| Key                            | Default | Description                |
+|--------------------------------|---------|----------------------------|
+| `spring.cloud.stream.binder.servlet.prefix`         | `stream` | The prefix for the URL paths |
+| `spring.cloud.stream.binder.servlet.buffer-timeout-seconds` | 10 | The buffer size in seconds to store messages from the output channels. |
+| `spring.cloud.stream.binder.servlet.receive-timeout-millis` | 100 | The timeout for send and receive if POST has a linked output channel. Only relevant if the message processing is asynchronous. |
