Spring Data Redis
=======================

The primary goal of the [Spring Data](http://projects.spring.io/spring-data/) project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.
This modules provides integration with the [Redis](http://redis.io/) store. 

# Docs

You can find out more details from the [user documentation](http://docs.spring.io/spring-data/data-redis/docs/current/reference/html/) or by browsing the [javadocs](http://docs.spring.io/spring-data/data-redis/docs/current/api/).

# Examples

For examples on using the Spring Data Key Value, see the dedicated project, also available on [GitHub](https://github.com/spring-projects/spring-data-keyvalue-examples)

# Artifacts

## Maven configuration

Add the Maven dependency:

```xml
<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-redis</artifactId>
  <version>${version}.RELEASE</version>
</dependency>
```

If you'd rather like the latest snapshots of the upcoming major version, use our Maven snapshot repository and declare the appropriate dependency version.

```xml
<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-redis</artifactId>
  <version>${version}.BUILD-SNAPSHOT</version>
</dependency>

<repository>
  <id>spring-libs-snapshot</id>
  <name>Spring Snapshot Repository</name>
  <url>http://repo.spring.io/libs-snapshot</url>
</repository>
```

## Gradle 

```groovy
repositories {
   maven { url "http://repo.spring.io/libs-milestone" }
   maven { url "http://repo.spring.io/libs-snapshot" }
}

// used for nightly builds
dependencies {
   compile "org.springframework.data:spring-data-redis:${version}"
}
```

# Usage (for the impatient)

* Configure the Redis connector to use (here [jedis](https://github.com/xetorthio/jedis)):

```xml
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:p="http://www.springframework.org/schema/p"
  xsi:schemaLocation="
  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
  
  <bean id="jedisFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"/>
  
  <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"
      p:connection-factory="jedisFactory"/>
</beans>
```

* Use `RedisTemplate` to interact with the Redis store:

```java
String random = template.randomKey();
template.set(random, new Person("John", "Smith"));
```

* Use Redis 'views' to execute specific operations based on the underlying Redis type:

```java
ListOperations<String, Person> listOps = template.listOps();
listOps.rightPush(random, new Person("Jane", "Smith"));
List<Person> peopleOnSecondFloor = listOps.range("users:floor:2", 0, -1);
```

# Building

Spring Data Redis uses Maven as its build system. 
Running the tests requires you to have a RedisServer running at its default port. Using the `-D runLongTests=true` option executes additional Pub/Sub test.

```bash
    mvn clean install
```

You can alternatively use the provided `Makefile` which runs the build plus downloads and spins up the following environment:

* 1 Single Node
* HA Redis (1 Master, 2 Replicas, 3 Sentinels).
* Redis Cluster (3 Masters, 1 Replica) 

```bash
    make test
```
