Spring Security

Spring Security provides security services for the Spring IO Platform. Spring Security 3.1 requires Spring 3.0.3 as a minimum and also requires Java 5.

For a detailed list of features and access to the latest release, please visit Spring projects.

Downloading Artifacts

See downloading Spring artifacts for Maven repository information.


Be sure to read the Spring Security Reference. Extensive JavaDoc for the Spring Security code is also available in the Spring Security API Documentation.

Quick Start

We recommend you visit Spring Security Reference and read the "Getting Started" page.

Building from Source

Spring Security 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.


Git and the JDK7 build.

Be sure that your JAVA_HOME environment variable points to the jdk1.7.0 folder extracted from the JDK download.

Check out sources

git clone

Install all spring-\* jars into your local Maven cache

./gradlew install

Compile and test; build all jars, distribution zips, and docs

./gradlew build

Discover more commands with ./gradlew tasks. See also the Gradle build and release FAQ.
