spring 与Hibernate集成的配置
首先建个web项目，导入所需要的包，包名在这列出：
hibernate3.3所用到的jar包：antlr-2.7.6.jar 开源语法分析生成器(lib\required)commons-collections-3.1.jar Commons集合类库，与连接池有关(lib\required)dom4j-1.6.1.jar xml解析类库(lib\required)javassist-3.9.0.GA.jar 分析，编辑和创建java字节码类库(lib\required)jta-1.1.jar 事务处理api (lib\required) slf4j-api-1.5.8.jar 日志处理 (lib\required)-->用log4j实现hibernate3.jar 核心ehcache-1.2.3.jar 二级缓存（lib\optional\ehcache）Spring2.5安装包所用的jar包：dist\spring.jarlib\aspectj\aspectjweaver.jar、aspectjrt.jarlib\cglib\cgligb-nodep-2.1_3.jarlib\j2ee\common-annotations.jarlib\jakarta-commons\commons-logging.jar 、commons-dbcp.jar、commons-pool.jarlib\log4j\log4j-1.2.15.jar 供srping与hibernate使用的日志记录jar包lib\slf4j\ slf4j-log4j12-1.5.0.jar 日志转换jar包，实现把log4j.jar包适配到slf4j标准。
