网上搜了一下很多都说是asm-2.2.3.jar包冲突，可是我项目中不放这个jar包也一样报错。而且这个错误好像一会没有一会我重启TOMCAT就又有错了。

Answer 2

如果dataSource和sessionFactory是自动生成的，那就没问题！
注意这里：Caused by: java.lang.NoClassDefFoundError: org/objectweb/asm/Type检查下你的asm.jar

Answer 3

org/objectweb/asm/Type 这个类对应的class 加到启动服务的classpath里面

Answer 4

asm.jar
肯定有，看看有没有org/objectweb/asm/Type
asm-2.2.3.jar包冲突，不是这个错！

Answer 5

创建bean失败，缺少asm.jar jar包
