struts2.3.7+spring3.0.5
环境：struts2.3.7+spring3.0.5
我的目录结构图如下：
注意一下，上面截图是分两部分来弄得，所以有些重复，在jar包的部分，注意一下就够了，总共15个jar包。

我是基于这个环境来配置我的struts2.1.8.1+spring3.0.2：
struts2 所需的jar包：
commons-fileupload-1.2.1.jar
commons-logging-1.0.4.jar
freemarker-2.3.15.jar
ognl-2.7.3.jar
struts2-core-2.1.8.1.jar
xwork-core-2.1.6.jar
struts2-spring-plugin-2.1.8.1.jar //整合spring所需jar包
spring3 所需的jar包
org.springframework.asm-3.0.2.RELEASE.jar
org.springframework.beans-3.0.2.RELEASE.jar
org.springframework.context-3.0.2.RELEASE.jar
org.springframework.core-3.0.2.RELEASE.jar
org.springframework.expr
ession-3.0.2.RELEASE.jar
org.springframework.web-3.0.2.RELEASE.jar
严重: Dispatcher initialization failed java.lang.RuntimeException: java.lang.reflect.InvocationTargetException 问题解决 ：
需要引入javassist-3.7.ga.jar
java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils
缺lang包
包的问题，因为我是struts2.X+spring3.X，而我参考别人的例子是struts2.X+spring2.X的，然后我就百度struts2+spring3的，看别人是怎么加包的，然后就把我的项目的包重新导入了一遍，然后就debug，观察console，根据里面的错误来百度下，就知道自己错在哪里，缺什么包了。
