Spring4+Hibernate4整合经验：事务配置导致的java.lang.NoSuchMethodError异常
最近在做项目的时候，升级之前的项目框架，从spring3+hibernate3升级到spring4+hibernate4+shiro框架的时候，遇到了一个nosuchmethod的异常问题，网上大部分资料都是说jar冲突问题，但是jar使用mvn控制的，冲突都解决了，仍然报这个异常，并且提示的是applicationContext.xml上下文环境配置文件里的异常异常代码如下：

beans>配置文件比较乱，是早起配置的一个spring+hibernate+ibatis的框架，在上下文环境中，看到涉及到proxy的配置项是：
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />
因为找不到其他的解决办法，那么就关于此处的配置升级到spring4.0的配置，看是否能解决此问题，以下是修改后的配置文件（略作整理）：

@Transactional 注解可以被应用于接口定义和接口方法、类定义和类的 public 方法上。
Spring团队的建议是你在具体的类（或类的方法）上使用 @Transactional 注解，而不要使用在类所要实现的任何接口上。
@Service
@Transactional(rollbackFor=Exception.class) //对当前类的所有方法起作用
@SuppressWarnings("serial")
public class ButtonBo extends GlobalBo {
....
@Transactional(propagation = Propagation.NOT_SUPPORTED, readOnly = true) //具体方法上
public Button findButton(String buttonid) throws BaseException {
return hibernateEntityDao.get(Button.class, buttonid);
}
}
