1.初次尝试产生以上这个问题,很明显,就是jar包没有导入完整,但是到底缺那些呢?这个可以将strtus自带的war放到tomcat下面去运行,看哪个可以

正常运行,就将那个包下面的jar全部拷贝过来就可以了,哈哈。只多不少,然后再尝试着删就可以了

网上的所谓攻略经常忽略javassist这个jar包,他不存在于lib下,而存在于app下的某个war中。

2.想要判断包名org.apache.struts2.dispatcher.FilterDispatcher是否拼写正确,可以在.java文件中import一下,

如果拼写正确自然不会报错,否则。。。

3.将struts的包引入工程的同时也要将所有的jar拷贝到WEB-INF/lib目录下,所以最好就是先copy然后将WEB-INF/lib下面的引入工程就好了。

下面两张图很好的说明了引入的jar是否存在WEB-INF/lib下面。

错误的引入,jar没有保存到WEB-INF/lib下面





正确的引入





4.如果以上问如果以上问题都解决完了,还是提示缺少某些jar包的话可以考虑查看Tomcat的classpath,那些缺少的jar包放到里面去:在Eclipes的servers view 中双击Tomcat-&gt;Open launch configuration 进入Edit configuration 界面,然后增加tomcat启动加载的jar包。这样tomcat每次启动都会自动加载这些jar,当然此方法利弊参半,请慎重考虑。
5.
严重: Dispatcher initialization failed
Unable to load configuration. - action - file:/D:/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/StrutsDemo/WEB-INF/classes/struts.xml:8:69


看到此问题,我首先想到了Google,结果告诉我缺少包,可是我的包已经全了啊,感觉不对,回来继续看日志,往下一下,豁然开朗(见红色部分),原来配置文件拼写错误,唉。
