* Add Validation to HTTP Inbound * Pull a validation functionality from `WebFluxInboundEndpoint` to its super class `BaseHttpInboundEndpoint` making a validation available for the `HttpRequestHandlingEndpointSupport` as well * Do the same for the `validator()` option in DSL for the `HttpInboundEndpointSupportSpec` * Add `validator` XML attribute for both HTTP and WebFlux inbound endpoint XSDs * Test parsers for a new `validator` option * Document validation in the `http.adoc` * Apply some polishing in the `http.adoc`, as well as in the `HttpRequestHandlingEndpointSupport` JavaDocs * Clarify in `webflux.adoc` that validation is applied for the `Publisher` items before the payload is finally built for the message to send. * Add WebFlux into the table of endpoints in the `endpoint-summary.adoc` * * Remove unused imports * Fix `SimpleMessageListenerContainerSpec` for deprecated `txSize` option
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
