struts2配置-总找不到action
报错总是找不到action
strust.xml放在WEB-INF目录下
对struts2的filter做如下配置：
<filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> <init-param> <param-name>config</param-name> <param-value>struts-default.xml,struts-plugin.xml,WEB-INF/struts.xml</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
仔细查看tomcat日志，发现如下问题
严重: Exception starting filter struts2 Caught exception while loading file struts-default.xml - [unknown location] at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.loadConfigurationFiles(XmlConfigurationProvider.java:839) at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.loadDocuments(XmlConfigurationProvider.java:131) at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.init(XmlConfigurationProvider.java:100) at com.opensymphony.xwork2.config.impl.DefaultConfiguration.reload(DefaultConfiguration.java:130) at com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration(ConfigurationManager.java:52) at org.apache.struts2.dispatcher.Dispatcher.init_PreloadConfiguration(Dispatcher.java:395) at org.apache.struts2.dispatcher.Dispatcher.init(Dispatcher.java:452) at org.apache.struts2.dispatcher.FilterDispatcher.init(FilterDispatcher.java:201) at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:295) at org.apache.catalina.core.ApplicationFilterConfig.setFilterDef(ApplicationFilterConfig.java:422) at org.apache.catalina.core.ApplicationFilterConfig.<init>(ApplicationFilterConfig.java:115) at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:4072) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4726) at org.apache.catalina.startup.HostConfig.checkResources(HostConfig.java:1284) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1382) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:306) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:142) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1389) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1653) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1662) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1642) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.ClassCastException: org.apache.xerces.parsers.XML11Configuration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration at org.apache.xerces.parsers.DOMParser.<init>(Unknown Source) at org.apache.xerces.parsers.DOMParser.<init>(Unknown Source) at org.apache.xerces.jaxp.DocumentBuilderImpl.<init>(Unknown Source) at org.apache.xerces.jaxp.DocumentBuilderFactoryImpl.newDocumentBuilder(Unknown Source) at com.sun.org.apache.xalan.internal.xsltc.trax.SAX2DOM.<init>(SAX2DOM.java:69) at com.sun.org.apache.xalan.internal.xsltc.runtime.output.TransletOutputHandlerFactory.getSerializationHandler(TransletOutputHandlerFactory.java:187) at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl.getOutputHandler(TransformerImpl.java:392) at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerHandlerImpl.setResult(TransformerHandlerImpl.java:137) at com.opensymphony.xwork2.util.DomHelper$DOMBuilder.setup(DomHelper.java:213) at com.opensymphony.xwork2.util.DomHelper$DOMBuilder.<init>(DomHelper.java:198) at com.opensymphony.xwork2.util.DomHelper$DOMBuilder.<init>(DomHelper.java:189) at com.opensymphony.xwork2.util.DomHelper$DOMBuilder.<init>(DomHelper.java:175) at com.opensymphony.xwork2.util.DomHelper.parse(DomHelper.java:115) at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.loadConfigurationFiles(XmlConfigurationProvider.java:830) ... 21 more
解决办法：
将strtus.xml放回到src目录下，去掉struts2 filter中struts.xml文件位置的配置
