JsonHeaders Regression
JIRA: https://jira.springsource.org/browse/INT-3285 Spring Integration 3.0 introduced the `JsonHeaders` and populates them from a request AMQP Message to the SI Message. In the case of the `AmqpInboundGateway` and `JsonMessageConverter`, if the SI flow doesn't do anything with `JsonHeaders` they are returned to the `AmqpInboundGateway` for reply Message and may override correct values provided by `JsonMessageConverter` in the `DefaultAmqpHeaderMapper`. This fix provides the check for headers from the reply Message's `MessageProperties` and populates `JsonHeaders` if the `MessageProperties` doesn't contains the `__TypeId__` header already. Note, it is just a fix for regression to restore previous behavior. There is maybe a reason to revise (Another JIRA) all standard AMQP headers and populate them from SI `MessageHeaders` in the `DefaultAmqpHeaderMapper`, only if they haven't been populated by `MessageConverter` before. **Cherry-pick to 3.0.x**
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
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
