折腾2天还没解决 谢谢帮忙
xml-apis.jar
xerces.jar
中都有这个类，应该是冲突了，你这么多框架依赖，估计不好办呐
包冲突吧 把你包的截图发出来。
也把applicationContext.xml源码放出来吧
应该是你的xml文件的问题，把applicationContext.xml贴出来看看。
Caused by: java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setAttribute(Ljava/lang/String;Ljava/lang/Object;)V
DocumentBuilderFactory里的setAttribute方法是abstract的，应该是加了含有javax.xml.parsers.DocumentBuilderFactory类的jar包导致的
这些jar包里都有DocumentBuilderFactory类，找找你的有没有冲突的

spring配置文件的格式有问题，不符合规范，解析不了了。
xml-apis.jar
xerces.jar
xmlParserAPIs.jar
都有冲突的类
有包没有导入 把你的applicationxml贴出来看看的。
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
