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"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    </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"

    </filter-mapping>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>


</web-app>

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：

这里我们发现Console是很干净的，没有警告和错误。
