不行，必须爆粗口了。
妈的，这个垃圾东西整死我了。（不是指struts2垃圾）
哇，真的烦。
w3c教程是不错，可是太老了啊，有些教程多少应该更新一下比较好，坑太多了。
让我想一想第一个bug。
1、org.apache.struts2.dispatcher.FilterDispatcher过时
如果采用struts2-core-2.1.3.jar，则采用上面的。

但是struts2-core-2.3.X.jar，采用
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter。

然而不巧，我也不知道哪个版本弃用的，现在我用的是struts2-core-2.5.17.jar，没有ng包，所以需要采用
org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter。

当然当我在eclipse中修改好后，tomcat无法启动，我特么？？？？！！！！！，搞不懂原因啊，至今没明白，行吧，我换个IntelliJ IDEA，行吧。新建个项目，把代码搬过来，包也搬过来，又是同样的地方报错？？？？！！！！！（这里是我没用明白IntelliJ IDEA）
cannot resolve class StrutsPrepareAndExecuteFilter？？？
已经把包复制到WEB-INF/lib目录下，怎么还报错？？？
在IntelliJ IDEA中，直接复制包是没有意义的。
导包正确姿势：
这里写图片描述

完成这些后，上面的报错就会取消了，然后又有各种报错，shift。

关注点一直在：
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]
我恨啊，百度了几个小时，各种方法都没用，禁锢在错误一般重点在前几行的思想中。

仔细往下看就会发现是log4j的问题，我根本没有导入过这个包。我也不知道哪里用到过，教程中只导入logging包，不管这么多，又导入了跟log4j相关的一些包。错误终于变了，哈哈哈哈，是变了，还是有，干。

Caused by: java.lang.NoClassDefFoundError: Lorg/apache/logging/log4j/Logger;

3、


java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils

很简单，导包lang3。

结果：

真的是老泪纵横啊啊啊啊啊啊！！！！

下面是项目依赖的所有包：

可能有多的吧，具体我也不能确定，总之终于能跑了啊啊啊。
