项目已经进行一段了，今天要给项目添加hibernate的二级缓存，在hibernate3.6.10的文件夹下没有找到ehcache的jar包，就没有导入任何jar包。
首先在Spring的配置文件添加这样的配置信息：
<bean id="sessionFactory"上面这段配置文件的后三个property是新添加的。同时添加了ehcache.xml配置文件：
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!-- 指定hibernate的配置文件位置 -->
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
<!-- 打开hibernate二级缓存 -->
<property name="hibernate.cache.use_second_level_cache" value="true"></property>
<!-- 指定hibernate的二级缓存 -->
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider"></property>
<!-- 启动"查询缓存" -->
<property name="hibernate.cache.use_query_cache" value="true"></property>
<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
<diskStore path="d:/ehcache"></diskStore>
<defaultCache maxElementsInMemory="1000" eternal="false"
timeToIdleSeconds="120" timeToLiveSeconds="180" overflowToDisk="true"></defaultCache>
</ehcache>
在其中一个*.hbm.xml添加<cache usage="read-only"/>，然后开始测试，结果报错了，错误信息如下：
18:09:58,419 ERROR ContextLoader:215 - Context initialization failed
