struts2.1笔记06：struts2开发环境的搭建实际操作出现的问题
1.我根据新建一个struts工程之后，启动报错，如下：

后来我在网上查找，发现是struts2.3.24运行起来，不仅需要几个基本的jar包，还需要javassist-3.11.0.GA.jar，我添加这个jar包到工程中，如下图：
然后再次运行这个struts2工程，然后发现报错发生了变化，如下图：

对比上下两次报错，发现这个添加javassist-3.11.0.GA.jar，解决了：严重: Dispatcher initialization failed
但是还有一个错误没有解决，这个错误是：严重: Exception starting filter struts2
这里说明一下：Javassist是一个开源的分析、编辑和创建Java字节码的类库。是由东京工业大学的数学和计算机科学系的 Shigeru Chiba （千叶 滋）所创建的。它已加入了开放源代码JBoss 应用服务器项目,通过使用Javassist对字节码操作为JBoss实现动态AOP框架。
2.
Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang3.StringUtils，网友根据这个报错的解读是，缺少添加的commons-lang3-3.1.jar,这个jar包是：
跟java.lang这个包的作用类似，Commons Lang这一组API也是提供一些基础的、通用的操作和处理，如自动生成toString()的结果、自动实现hashCode()和equals()方法、数组操作、枚举、日期和时间的处理等等。
这一组API的所有包名都以org.apache.commons.lang开头，共有如下8个包：
org.apache.commons.lang
org.apache.commons.lang.builder
org.apache.commons.lang.enum
org.apache.commons.lang.enums
org.apache.commons.lang.exception
org.apache.commons.lang.math
org.apache.commons.lang.mutable
org.apache.commons.lang.time
然后我添加这个jar包之后，再次运行这个struts工程，发现：

到这里我们发现，没有发现报错了，说明问题成功解决了，这里同时也出现一个警告：
警告: Could not find action or result: /struts2/
我找了很久才发现这个是web.xml文件中:
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<url-pattern>/*</url-pattern>
</filter-mapping> <welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list> </web-app>
这里index.html是错误的，因为工程下没有这个文件，如下图：
所以我改一下，改为：
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

虽然我这里struts2工程中struts.xml没有任何配置，但是还是可以运行的，这里我运行这个struts2工程，如下图：
