How to create cache expiry policy in ignite server by xml?

This is my example-default.xml,

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:util="http://www.springframework.org/schema/util"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/util
        http://www.springframework.org/schema/util/spring-util.xsd">
    <bean abstract="true" id="ignite.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
        <!-- Set to true to enable distributed class loading for examples, default is false. -->
        <property name="peerClassLoadingEnabled" value="true"/>

        <!-- Enable task execution events for examples. -->
        <property name="includeEventTypes">
            <list>
                <!--Task execution events-->
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_STARTED"/>
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_FINISHED"/>
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_FAILED"/>
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_TIMEDOUT"/>
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_SESSION_ATTR_SET"/>
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_TASK_REDUCED"/>

                <!--Cache events-->
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_CACHE_OBJECT_PUT"/>
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_CACHE_OBJECT_READ"/>
                <util:constant static-field="org.apache.ignite.events.EventType.EVT_CACHE_OBJECT_REMOVED"/>
            </list>
        </property>

        <property name="CacheExpiryPolicy">
        <bean class="org.apache.ignite.configuration.CacheConfiguration">
           <property name="expiryPolicyFactory">
               <bean class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
                  <constructor-arg>
                      <bean class="javax.cache.expiry.Duration">
                          <constructor-arg value="MINUTES"/>
                          <constructor-arg value="5"/>
                      </bean>
                  </constructor-arg>
               </bean>
           </property>
        </bean>
        </property>

But the above gives Bean property 'CacheExpiryPolicy' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

How I can solve this?

I found an apache-ignite-users forum question on this.

Please refer to this here

So, the final updated xml according to that forum reference is :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://www.springframework.org/schema/util
        http://www.springframework.org/schema/util/spring-util.xsd">

    <!-- Added cache expiry policy -->
    <bean id="cacheExpiryPolicy"

        <property name="includeEventTypes">

Here is the example from the documentation:

<property name="cacheConfiguration">
            <list>
                <bean class="org.apache.ignite.configuration.CacheConfiguration">
                    <property name="name" value="cacheWithExpiryPolicy"/>
                    <property name="expiryPolicyFactory">
                        <bean class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
                            <constructor-arg>
                                <bean class="javax.cache.expiry.Duration">
                                    <constructor-arg value="MINUTES"/>
                                    <constructor-arg value="5"/>
                                </bean>
                            </constructor-arg>
                        </bean>
                    </property>
                </bean>
            </list>
</property>
