Hazelcast Spring Integration

Beans Namespace

<bean id="instance" class="com.hazelcast.core.Hazelcast" factory-method="newHazelcastInstance">
    <constructor-arg>
        <bean class="com.hazelcast.config.Config">
            <property name="groupConfig">
                <bean class="com.hazelcast.config.GroupConfig">
                    <property name="name" value="dev"/>
                    <property name="password" value="pwd"/>
                </bean>
            </property>
            <!-- and so on ... -->
        </bean>
    </constructor-arg>
</bean>
<bean id="map" factory-bean="instance" factory-method="getMap">
    <constructor-arg value="map"/>
</bean>

Hazelcast Namespace

• Add namespace xmlns:hz="http://www.hazelcast.com/schema/config" to beans tag in context file:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:hz="http://www.hazelcast.com/schema/config"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
                http://www.hazelcast.com/schema/config
                http://www.hazelcast.com/schema/config/hazelcast-spring.xsd">

• Use hz namespace shortcuts to declare cluster, its items and so on.
