Spring整合Hibernate的配置问题！

Spring整合Hibernate的配置问题！
配置文件applicationContext.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<!-- 配置数据源 -->
<bean id="ppDataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver">
</property>
<property name="url" value="jdbc:mysql://localhost:3306/playpark">
</property>
<property name="username" value="root">
</property>
<property name="password" value="root">
</property>
</bean>
<bean id="ppSessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="ppDataSource"></property>
<property name="mappingResources">
<list>
<value>user/bean/User.hbm.xml</value>
<value>user/bean/Friend.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">;
org.hibernate.dialect.MySQLInnoDBDialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
</props>
</property>
</bean>
</beans>

启动tomcat发布项目的时候报错：
DisposableBeanAdapter - Invoking destroy method 'close' on bean with name 'ppDataSource'
ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ppSessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V

Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V

为什么会出现NoSuchMethodError?
配置文件应该没问题的啊。
该有的包也全有了的啊，就是不知道为什么会有这种错误。
小弟以前没搞过Spring,求教大家帮忙了！

Answer 1

spring里的用了asm.jar，hibernate里也用了asm.jar，但spring和hibernate用的版本不一样，spring用的较新，hibernate用的较老，他们一个用的visit方法参数是string,string,string[],string，另一个用的是string,string,string,string[],新的asm.jar只有参数为string,string,string,string[]的visit方法，因此就抱NoSuchMethodError了。解决方案是把hibernate和spring都升到最新的版本试一下。
或搜索关键字org.objectweb.asm.ClassVisitor，网上说的很多。

Answer 2

asm.jar可能冲突了，你去掉一个版本低的就好了
