hibernate4下一个可用的hibernate.properties：

jdbc.driverClassName=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/hibernate?characterEncoding=UTF-8jdbc.username=usernamejdbc.password=passwordhibernate.dialect=org.hibernate.dialect.MySQLDialect
     #hibernate.current_session_context_class=threadhibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext 
       hibernate.cache.use_query_cache=truehibernate.jdbc.batch_size=50
       hibernate.cache.use_second_level_cache=true#hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory#hibernate.cache.provider_class=org.hibernate.cache.ehcache.EhCacheRegionFactory // hibernate3hibernate.cache.provider_class=org.hibernate.cache.spi.RegionFactoryhibernate.cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory
       hibernate.hbm2ddl.auto=update
      hibernate.show_sql=true

 

 

pom.xml中相关配置：

             
      
       4.3.9.Final
              
      
       4.1.6.RELEASE
              
      
       5.1.35
              
      
       UTF-8
          
     

hibernate.properpties中关于二级缓存的配置：

hibernate.cache.use_second_level_cache=true

hibernate.cache.provider_class=org.hibernate.cache.spi.RegionFactory

hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory

报错信息：

原因及解决办法：

缺少jar:hibernate-ehcache

添加：

                 
      
       org.hibernate
                  
      
       hibernate-ehcache
                  
      
       ${hibernate-version}
              
     

org.hibernate.HibernateException: save is not valid without active transaction

 at org.hibernate.context.internal.ThreadLocalSessionContext$TransactionProtectionWrapper.invoke(ThreadLocalSessionContext.java:352)

 at com.sun.proxy.$Proxy24.save(Unknown Source)

 at com.xx.dao.BaseDao.save(BaseDao.java:31)

对于提示*** is not valid without active transaction 的错误

可以在Hibernate的配置文件中做如下修改

<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>（Hibernate4）

对于Hibernate3.x，可以直接把上述设置删除，就不会报错了，具体原因尚不清楚。

须知：几乎所有正常的操作都必须在transcation.isActive()条件下才能执行。get,load,save, saveOrUpdate,list都属于这类。

日志打印：

增加slf4j的jar，譬如log4j可选择添加slf4j-api.jar和slf4j-log4j12.jar
