The primary goal of the 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. As the name implies, the Key Value modules provides integration with key value stores such as Redis and Riak.

For examples on using the Spring Data Key Value, see the dedicated project, also available on GitHub

Read the main project website and the User Guide. Look at the source code and the JavaDocs. For more detailed questions, use the forum. If you are new to Spring as well as to Spring Data, look for information about Spring projects.

For those in a hurry:

• Download the jar through Maven:

  <dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.0.0.BUILD-SNAPSHOT</version>
  </dependency> 
  
  <repository>
    <id>spring-maven-snapshot</id>
    <snapshots><enabled>true</enabled></snapshots>
    <name>Springframework Maven SNAPSHOT Repository</name>
    <url>http://maven.springframework.org/snapshot</url>
  </repository> 
  

• Configure the Redis connector to use (here jedis):

  <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.keyvalue.redis.connection.jedis.JedisConnectionFactory"/>
    
    <bean id="redisTemplate" class="org.springframework.data.keyvalue.redis.core.RedisTemplate"
        p:connection-factory="jedisFactory"/>
  </beans>
  

• Use RedisTemplate to interact with the Redis store:

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

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

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

• Download the jar through Maven:

  <dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-riak</artifactId>
    <version>1.0.0.BUILD-SNAPSHOT</version>
  </dependency> 
  
  <repository>
    <id>spring-maven-snapshot</id>
    <snapshots><enabled>true</enabled></snapshots>
    <name>Springframework Maven SNAPSHOT Repository</name>
    <url>http://maven.springframework.org/snapshot</url>
  </repository> 
  

• Configure the RiakTemplate in your Spring ApplicationContext:

  <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="riakTemplate" class="org.springframework.data.keyvalue.riak.core.RiakTemplate"
        p:defaultUri="http://localhost:8098/riak/{bucket}/{key}"
        p:mapReduceUri="http://localhost:8098/mapred"/>
  
  </beans>
  

• Use the RiakTemplate in your code:

  Java:
  -----
  
  MyObject obj = new MyObject("value1", "value2");
  riakTemplate.set("mybucket", "mykey", obj);
  
  Map returnObj = riakTemplate.getAsType("mybucket", "mykey", Map.class);
  
  Groovy:
  -----
  
  def obj = [first: "value1", second: "value2"]
  riakTemplate.set("mybucket", "mykey", obj)
  

Here are some ways for you to get involved in the community:

• Get involved with the Spring community on the Spring Community Forums. Please help out on the forum by responding to questions and joining the debate.
• Create JIRA tickets for bugs and new features and comment and vote on the ones that you are interested in.
• Github is for social coding: if you want to write code, we encourage contributions through pull requests from forks of this repository. If you want to contribute code this way, please reference a JIRA ticket as well covering the specific issue you are addressing.
• Watch for upcoming articles on Spring by subscribing to springframework.org

Before we accept a non-trivial patch or pull request we will need you to sign the contributor's agreement. Signing the contributor's agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. Active contributors might be asked to join the core team, and given the ability to merge pull requests.
