struts2启动报错-Class-com-opensymphony-xwork2-spring-SpringObjectFactory-File-SpringObjectFactory-java-1

严重: Exception starting filter struts2

Class: com.opensymphony.xwork2.spring.SpringObjectFactory
File: SpringObjectFactory.java
Method: getClassInstance
Line: 209 - com/opensymphony/xwork2/spring/SpringObjectFactory.java:209:-1
Caused by: java.lang.NullPointerException at com.opensymphony.xwork2.spring.SpringObjectFactory.getClassInstance(SpringObjectFactory.java:209)

原因两个：
1.lib中多导入包的大原因：去掉struts2-spring-plugin-2.1.8包即可，因为没有用到spring。
2.还有的原因是用spring了，却没加监听器，在web.xml里面加上

<context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:applicationContext*.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
