spring与struts2整合出现常见错误

错误信息
严重: Exception starting filter struts2
Unable to load configuration. - bean - jar:file:/F:/Struts2/Struts2/WebRoot/WEB-

INF/lib/struts2-core-2.1.2.jar!/struts-default.xml:46:178
解决办法
少jar包，添加
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar



错误信息
org.springframework.beans.factory.BeanCreationException: Error creating bean with name

'sessionFactory' defined in ServletContext resource [/WEB-

INF/classes/applicationContext.xml]: Invocation of init method failed; nested exception is

java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit

(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V
解决办法：
Spring中的asm-xxx.jar 和 Hibernate中的 asm.jar 冲突，移除 spring aop 中的 asm-xxx.jar 或者

出现 action 为null 时移除 spring aop



错误信息
Exception starting filter struts2
Cannot locate the chosen ObjectFactory implementation: The

com.opensymphony.xwork2.ObjectFactory implementation class - [unknown location]
解决办法：
少jar包，添加struts2-spring-plugin-2.0.14.jar
struts.xml中，加上一句话
<constant name="struts.objectFactory" value="spring"/>

经过在网上查找原因，说是xerces-2.6.2.jar与hibernate3.jar里面出现冲突，于是删除xerces-2.6.2.jar再重新启动tomcat6问题解决，程序正常运行
