org.objectweb.asm.ClassVisitor.visit

开发工具：MyEclipse5.5GA；Spring2.0；Hibernate3.2.5GA
程序运行时报如下错误：
java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V

从出错信息中可以看出与asm包有关，打开lib目录发现里面和asm有关的分别有：
asm.jar
asm-2.2.3.jar
asm-attrs.jar
asm-commons-2.2.3.jar
asm-util-2.2.3.jar
一一排除，最后在删除asm-2.2.3.jar后，程序成功运行，这是由于Spring和Hibernate共用了一些jar包引发的错误。
