解释一下：我的Action继承自己写的一个抽象类

------解决方案--------------------
java.lang.NoClassDefFoundError: org/objectweb/asm/Type
配置文件里的contactServices对应的类没有找到。
------解决方案--------------------
asm是不是这个jar包冲突或者没有加进来啊？
------解决方案--------------------
缺少Jar包 org/objectweb/asm/Type
在spring包下找asm包，添加进去再启动，可能还会缺少其他包，如果启动成功就好了，如果没有成功就继续找呗。
------解决方案--------------------
缺少jar包了，自己去google搜索 org/objectweb/asm/Type 应该就会有对应的jar提示，自己整合要想要完美jar(不多不少那种)只有这样慢慢找了。
