#ZooKeeper Spring

Annotation-driven injection of values from ZooKeeper into Spring Beans

###Maven

<dependency>
    <groupId>com.ryantenney.zookeeper</groupId>
    <artifactId>zookeeper-spring</artifactId>
    <version>1.0.0-SNAPSHOT</version>
</dependency>

###Basic Usage

Include in your application context:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:c="http://www.springframework.org/schema/c"
  xmlns:p="http://www.springframework.org/schema/p"
  xmlns:zk="http://www.ryantenney.com/schema/zookeeper"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                      http://www.ryantenney.com/schema/zookeeper http://www.ryantenney.com/schema/zookeeper/zookeeper-1.0.xsd">

  <zk:annotation-driven curator-framework="curatorFramework" />

  <zk:curator-framework id="curatorFramework" connect-string="127.0.0.1:2181">
    <zk:retry-policy>
      <bean class="org.apache.curator.retry.ExponentialBackoffRetry">
        <constructor-arg index="0" type="int" value="1000" />
        <constructor-arg index="1" type="int" value="3" />
      </bean>
    </zk:retry-policy>
  </zk:curator-framework>

</beans>

And annotate away:

@Component
public class SpringBean {

    @ZooKeeper("/foo")
    private String foo;

    @ZooKeeper("/bar")
    public void setBar(String bar) {
        // ...
    }

}
