spring +hibernate整合的问题，包重复

2007-08-08 15:36:17,406 ERROR [org.hibernate.proxy.BasicLazyInitializer] - CGLIB Enhancement failed: dao.User java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V at net.sf.cglib.core.ClassEmitter.begin_class(ClassEmitter.java:77)

Spring 和 Hibernate 共用的一些 jar 文件发生了版本冲突, 删除 WEB-INF/lib/asm-2.2.3.jar 然后重启 Tomcat.

asm-2.2.3.jar          asm.jar          asm-attrs.jar         asm-commons-2.2.3.jar         asm-util-2.2.3.jar
