Spring Operator 79f13d042c URL Cleanup
This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

# HTTP URLs that Could Not Be Fixed
These URLs were unable to be fixed. Please review them to see if they can be manually resolved.

* http://rss.cnn.com/rss/cnn_topstories.rss (200) with 1 occurrences could not be migrated:
   ([https](https://rss.cnn.com/rss/cnn_topstories.rss) result ClosedChannelException).
* http://wsf.cdyne.com/WeatherWS/Weather.asmx (200) with 1 occurrences could not be migrated:
   ([https](https://wsf.cdyne.com/WeatherWS/Weather.asmx) result ConnectTimeoutException).

# Fixed URLs

## Fixed But Review Recommended
These URLs were fixed, but the https status was not OK. However, the https status was the same as the http request or http redirected to an https URL, so they were migrated. Your review is recommended.

Barrier Sample

This example demonstrates the use of a process barrier component to suspend a thread until some asynchronous operation completes. The first example uses an HTTP Inbound Gateway, splits the request, sends the splits to rabbitmq and then waits for the publisher confirms. Finally, the results are returned to the caller.

The sample is a Spring Boot application that loads 2 contexts:

  • Client - Sends A,B,C to the server
  • Server - Web application

The server context has 3 integration flows:

http -> splitter -> amqp
     |-> barrier

amqp(Acks) -> aggregator -> barrier (release)

qmqp(inbound) -> nullChannel

The last flow drains the messages and allows the auto-delete queue to be removed when the application is closed.

Running the sample

$ gradlew :barrier:run

This will package the application and run it using the Gradle Application Plugin

Using an IDE such as SpringSource Tool Suite™ (STS)

In STS (Eclipse), go to package org.springframework.integration.samples.barrier, right-click Application and select Run as --> Java Application (or Spring Boot Application).

Output

The gateway (client) initiates a simple request posting "A,B,C" to the server and the server responds with the results. You should see the following output from the server:

++++++++++++ Replied with: Result: A: ack=true, B: ack=true, C: ack=true ++++++++++++

Error Handling

The second example uses a simple gateway to launch some asynchronous tasks and waits for those tasks to complete.

It shows how you might return an exception to the caller if one or more of those tasks fail.

An aggregator is used to aggregate the results; if there are no errors, the results are returned; if one or more errors occurred, an exception is sent to release the barrier; this is thrown to the caller and has all the consolidated results in a property.

You can run this example from an IDE, such as STS using the technique above; in this case, the class is ErrorHandlingApplication in the org.springframework.integration.samples.barrier package.

It sends a list of integers to the flow:

[2, 0, 2, 0, 2]

The zeros should fail and in stderr you should see the results:

ConsolidatedResultsException
[results=
[5
org.springframework.integration.transformer.MessageTransformationException:
  Failed to transform Message; nested exception is org.springframework.messaging.MessageHandlingException:
  Expression evaluation failed: 10 / payload; nested exception is java.lang.ArithmeticException: / by zero
