需要加上：  commons-logging.jar log4j-1.2.11.jar

 

问题  2  ：  Exception in thread "main"  org.springframework.beans.factory.BeanDefinitionStoreException  : Unexpected exception parsing XML document from class path resource [text.xml]; nested exception is java.lang.NoClassDefFoundError:  org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException

需要加上：  aspectjweaver.jar

 

问题  3  ：  Exception 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 org.springframework.aop.framework.AopConfigException  : Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

Caused by:  org.springframework.aop.framework.AopConfigException  : Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

需要加上：  cglib-2.1.3.jar

 

 

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

Caused by: java.lang.NoClassDefFoundError: org/objectweb/asm/Type

    at net.sf.cglib.core.TypeUtils.parseType(  TypeUtils.java:180  )

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
