JIRA: https://jira.spring.io/browse/INT-4365 It is much useful to configure the `notPropagatedHeaders` as a set of patterns to match. In this case we can filter a group of headers with the common prefix or suffix * Allow to configure `AbstractMessageProducingHandler.setNotPropagatedHeaders` as simple patterns; the `*` means filter all - not copy request headers at all - similar to `transformer` behavior * Add `ConsumerEndpointSpec.notPropagatedHeaders()` for Java DSL * Add `not-propagated-headers` to the `<service-activator>` Address PR comments; some other improvements * Fix `ConsumerEndpointSpec#notPropagatedHeaders()` log message * Improve `AbstractMessageProducingHandler.notPropagatedHeaders() logic so any `*` in the set of patterns eliminates all others since it has a highest priority * Expose `requires-reply` for the `<transformer>` as a `true` by default * Refactor a bit `AbstractStandardMessageHandlerFactoryBean` hierarchy to avoid duplicated code * Fix `message.adoc` * Add `noHeadersPropagation` flag to the `AbstractMessageProducingHandler` * Rework logic in the `updateNotPropagatedHeaders()` to store the array of patterns instead of `Set` to avoid extra operation on each message * Combine `noHeadersPropagation` with the `shouldCopyRequestHeaders()` in the `createOutputMessage()` for logic to determine if we should start the copy-headers procedure at all * Revert `AbstractMessageProducingHandler.selectiveHeaderPropagation` * Optimize `AmqpOutboundGatewayParserTests` performance from 3 secs to 0.5 Fix more NPEs in the `AbstractMessageProducingHandler`
Spring Integration

Checking out and Building
To check out the project and build from source, do the following:
git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build
NOTE: While Spring Integration runs with Java SE 6 or higher, a Java 8 compiler is required to build the project.
If you encounter out of memory errors during the build, increase available heap and permgen for Gradle:
GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'
To build and install jars into your local Maven cache:
./gradlew install
To build api Javadoc (results will be in build/api):
./gradlew api
To build reference documentation (results will be in build/reference):
./gradlew reference
To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)
./gradlew dist
Using Eclipse
To generate Eclipse metadata (.classpath and .project files), do the following:
./gradlew eclipse
Once complete, you may then import the projects into Eclipse as usual:
File -> Import -> Existing projects into workspace
Browse to the 'spring-integration' root directory. All projects should import free of errors.
Using IntelliJ IDEA
To generate IDEA metadata (.iml and .ipr files), do the following:
./gradlew idea
