Hibernate RMI 分布式二级缓存为什么对添加、删除、查询集合不会通知其他peer

我在本地部署了两个tomcat服务server1和server2,但是我在server1中查询或者修改单条数据的时候,server2中的缓存能做相应的变化,但是当在server1做查询所有集合、添加、删除操作的时候,server2的缓存没任何变化,具体配置文件如下
hibernate.cfg.xml
<hibernate-configuration>
  <session-factory>
  <!-- Database connection settings -->
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/ehcheTest?useUnicode=true&amp;characterEncoding=UTF-8&amp;mysqlEncoding=utf-8</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>

<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <!-- SQL dialect -->
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>



  <!-- Enable Hibernate's automatic session context management -->
  <property name="current_session_context_class">thread</property>

  <!-- Enable the second-level cache -->
  <property name="cache.use_second_level_cache">true</property>
<property name="cache.use_query_cache">true</property>   
  <property name="net.sf.ehcache.configurationResourceName">ehcache.xml</property>
  
  <property name="hibernate.cache.region.factory_class">
  net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory
  </property>
  <!-- Echo all executed SQL to stdout -->
  <property name="show_sql">true</property>

  <!-- Drop and re-create the database schema on startup -->
  <property name="hbm2ddl.auto">update</property>
<property name="hibernate.cache.region_prefix"></property>
  <mapping resource="com/nokia/test/Student.hbm.xml"/>
  </session-factory>
</hibernate-configuration>

server1 中的ehcache.xml
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
  <diskStore path="java.io.tmpdir"/>   
  <!--调用ehcache2的RMI-->
  <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"  
  properties="peerDiscovery=manual,rmiUrls=//192.168.10.167:40002/userIdcache"/>

<!--RMI监听40001端口-->
  <cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
  properties="hostName=192.168.10.167,port=40001,socketTimeoutMillis=2000"/>
    
  <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120"  
timeToLiveSeconds="120" overflowToDisk="true" diskSpoolBufferSizeMB="30"  
maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="120"  
memoryStoreEvictionPolicy="LRU">
  </defaultCache>
    
  <cache name="userIdcache"
  maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="1800" timeToLiveSeconds="0"
  overflowToDisk="true" diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000" diskPersistent="true"
  diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU">
  <!--监听配置-->
  <cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"   
  properties="replicateAsynchronously=true,replicatePuts=true,replicateUpdates=true,replicatePutsViaCopy=true,replicateUpdatesViaCopy=true,replicateRemovals=true" />
  </cache>
</ehcache>

server2中的配置文件和server1中只有这两个端口不同
<cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"  
  properties="peerDiscovery=manual,rmiUrls=//192.168.10.167: 40001 /userIdcache"/>

<!--RMI监听40001端口-->
  <cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
  properties="hostName=192.168.10.167,port= 40002 ,socketTimeoutMillis=2000"/>

model的配置文件如下
<hibernate-mapping package="com.nokia.test">
  <class name="Student" table="student">
  <cache usage="read-write" region="userIdcache"/>
  <id name="id" column="id">
  <generator class="native"/>
  </id>
  <property name="address" type="string"/>
  <property name="name" type="string"/>
  </class>
</hibernate-mapping>

查询单个对象代码如下 (可以同步缓存):
Session session = MySessionFactory.getSession();
String id = request.getParameter("stuId");
if(id != null) {
Student stu = (Student) session.get(Student.class, Long.valueOf(id)); 
request.setAttribute("student", stu);
}
session.close();

查询全部对象时(不能同步缓存):
Session session = MySessionFactory.getSession();
Query query = session.createQuery(" from Student");
query.setCacheable(true);
List<Student> result = query.list();
session.close();

删除时也不能同步:
String id = request.getParameter("id");
Student student = new Student();
student.setId(Long.valueOf(id));

Session session = MySessionFactory.getSession();
Transaction transaction = session.getTransaction();
transaction.begin();
session.delete(student);
transaction.commit();
session.close();
请高手指点一下,这是什么原因?
