最近整合spring4和hibernate4,beans.xml如下
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

spring和hibernate的版本都是4的,但测试时就是报java.lang.NoSuchMethodError: org.hibernate.Session.openSession()异常,后来查了好久,都说是hibernate4的版本需要spring4才能支持,但我的都是4的。然后我开始看我的beans.xml,发现原来这里错了:
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
改成
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
即可。
