Hibernate二级缓存问题

        在加入ehcache.xml配置文件时所产生的编译错误异常！

   net.sf.ehcache.CacheException: Error configuring from file:/F:/Struts2/Hibernate21/bin/ehcache.xml. Initial cause was Error configuring from input stream. Initial cause was null:5: Element <ehcache> does not allow nested <defaultCatch> elements.

  ehcache.xml文件内容：   

<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
 <diskStore path="d:/ehcache"/>
 <defaultCatch maxElementsInMemory="200" eternal="false"
 timeToIdleSeconds="50" timeToLiveSeconds="60" overflowToDisk="true"/>
 
 <cache name="com.hibernate.app.Student" maxElementsInMemory="200" eternal="false"
 timeToIdleSeconds="50" timeToLiveSeconds="60" overflowToDisk="true"/>

</ehcache>

 

 

 

hibernate.cfg.xml配置：

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

测试代码：

 

package com.hibernate.app;

import java.util.List;

import org.hibernate.Hibernate;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class HibernateTest {

 private static SessionFactory sessionFactory;

 static {
  try {

   sessionFactory = new Configuration().configure()
     .buildSessionFactory();

  } catch (Exception e) {
   e.printStackTrace();
  }
 }
 
 public static void main(String[] args){ 
   //启动session
   Session session = sessionFactory.openSession();
   Transaction tran = null;
   
   try{
    //开启事物
    tran = session.beginTransaction();
    
    /*Team team = new Team();
    team.setTeamName("team1");
    //向数据库中插入1200条数据

     Student stu = new Student();
     stu.setAge(20);
     stu.setName("zhangsan"+i);
     stu.setCardId("1002");
     stu.setTeam(team);
     
     team.getStudents().add(stu);
    }
    session.save(team);
    
    //提交事物
    tran.commit();*/
    System.out.println("从数据库中取得数据，将有sql语句生成begin!----------------------------------------");
    
    Session session1 = sessionFactory.openSession();
    Transaction tran1 = session1.beginTransaction();
    
    List<Student> list = session.createQuery("From Student s order by s.name asc").list();
    for(Student stu : list){
     
     System.out.println(stu.getName());
    }
    System.out.println("Over!----------------------------------------");
    tran1.commit();
    
    
    
    Session session2 = sessionFactory.openSession();
    Transaction tran2 = session1.beginTransaction();
    
    Student stu1 = (Student)session2.get(Student.class, "4028814d33acdb5b0133acdb5fe7000c");
    Student stu2 = (Student)session2.get(Student.class, "4028814d33acdb5b0133acdb5fe7000d");
    System.out.println("以下两条为缓存中取得的数据，因为没有sql语句被执行----------------------------------------");
    System.out.println(stu1.getName());
    System.out.println(stu2.getName());
    
    tran2.commit();
    
    
    
   }catch(Exception e){
    e.printStackTrace();
    if(null != tran){
     tran.rollback();
    }
   }finally{
     
    session.close();
   }
  }
 }

         最后万般无赖，我删除ehcache.xml配置文件，编译成功，但是接下来又有了新的问题，就是上边ehcache.xml配置文件所有的设置又该在什么地方设置呢？   郁闷了，

有遇到此问题的希望可以交流交流。
