當把struts2下所有的包放在lib下,啟動時的確會報錯(啥錯給忘了),最好是用到什么包自己加什么包,我最常用ssh所以~~~,一下錯誤經驗分享一下。
1。沒有加入spring包以前,只加入了struts2-spring-plugin-2.0.6.jar
2007-3-21 17:37:29 org.apache.catalina.core.StandardContext filterStart
嚴重: Exception starting filter struts2
Unable to load bean: type:com.opensymphony.xwork2.ObjectFactory
2。加入了spring包以后的工程
java.lang.NullPointerException
at com.opensymphony.xwork2.spring.SpringObjectFactory.getClassInstance (SpringObjectFactory.java:188)at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.verifyResultType (XmlConfigurationProvider.java:479)
3。/在web.xml文件中加入,問題解決
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
//listenre會自動在web-inf文件夾下尋找applicationcontext.xml文件,如果你的spring配置文件配置了好多,可以采取 context-param的參數來解決
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
4。struts2的標簽無法讀取
Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
at org.apache.struts2.views.jsp.TagUtils.getStack(TagUtils.java:58)
at org.apache.struts2.views.jsp.StrutsBodyTagSupport.getStack(StrutsBodyTagSupport.java:52)
在web.xml中加入
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping〉

經過本人測試主要是由于web.xml中少了如下listener的配置:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
