Previously, when the broker relay was shut down, the TCP client was closed and the relay sessions were left to find out about the shutdown as a result of their TCP connections being closed. This led to problems where an attempt could be made to use a session that was, in fact, in the process of being shut down. This commit updates the broker relay to explicitly close each of its relay sessions as part of its stop processing. As part of the broker relay being shut down explicitly close each of its relay sessions. It does so before closing the TCP client so that the relay sessions know that they are disconnected before their TCP connections are closed. The broker relay's publishing of availability events has also been improved. Prior to this commit, availability events were published based on the availability of any relay session. For example, this meant that a successfully established client relay session would result in an event being published indicating that the broker's available even if the system relay session was yet to be established. This commit updates the relay so that broker availability events are only published by the system relay session. This allows application code the use these events as an accurate indication of the availability of the broker. Clients that are interested in the broker's availability can find out through the use of heart beats or through the receipt of an ERROR frame in response to an attempt to communnicate with the broker.
Spring Framework
The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
The framework also serves as the foundation for Spring Integration, Spring Batch and the rest of the Spring family of projects. Browse the repositories under the SpringSource organization on GitHub for a full list.
Downloading artifacts
See downloading Spring artifacts for Maven repository information. Unable to use Maven or other transitive dependency management tools? See building a distribution with dependencies.
Documentation
See the current Javadoc and reference docs.
Getting support
Check out the Spring forums and the spring and spring-mvc tags on Stack Overflow. Commercial support is available too.
Issue Tracking
Report issues via the Spring Framework JIRA. Understand our issue management process by reading about the lifecycle of an issue. Think you've found a bug? Please consider submitting a reproduction project via the spring-framework-issues GitHub repository. The readme there provides simple step-by-step instructions.
Building from source
The Spring Framework uses a Gradle-based build system. In the instructions
below, ./gradlew is invoked from the root of the source tree and serves as
a cross-platform, self-contained bootstrap mechanism for the build.
prerequisites
Git and OpenJDK 8 early access build 100 or later
Be sure that your JAVA_HOME environment variable points to the jdk1.8.0 folder
extracted from the JDK download.
check out sources
git clone git://github.com/SpringSource/spring-framework.git
import sources into your IDE
Run ./import-into-eclipse.sh or read import-into-idea.md as appropriate.
Note: Per the prerequisites above, ensure that you have JDK 8 configured properly in your IDE.
install all spring-* jars into your local Maven cache
./gradlew install
compile and test, build all jars, distribution zips and docs
./gradlew build
... and discover more commands with ./gradlew tasks. See also the Gradle
build and release FAQ.
