问题 4 ： xception in thread "main" org.springframework.beans.factory.BeanCreationException :
Error creating bean with name 'logBean' defined in class path resource [text.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/objectweb/asm/Type

需要加上： asm.jar

错误：java.lang.NoClassDefFoundError: org/objectweb/asm/CodeVisitor的解决方法 在使用Spring的AOP编程时，会用到这几个lib： asm-2.2.2.jar asm-commons-2.2.2.jar asm-util-2.2.2.jar Hibernate使用如下lib： asm.jar asm-attrs.jar 其中asm-2.2.2.jar与asm.jar存在类上的冲突！！！ 使用其中之一或两者都使用，可能会出现如下错误： java.lang.NoClassDefFoundError: org/objectweb/asm/CodeVisitor java.lang.NoClassDefFoundError: org/objectweb/asm/commons/EmptyVisitor java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit。。。。。。 解决办法是： 1.去掉类路径上的关于Hibernate的3个lib asm.jar asm-attrs.jar cglib-2.1.3.jar 2.加入Spring中的以下4个lib asm-2.2.2.jar asm-commons-2.2.2.jar asm-util-2.2.2.jar cglib-nodep-2.1_3.jar
