struts2启动问题，竟然跟spring扯上了，难道使用struts2必须先使用spring吗

Question

自己的第一个例子，啥都没有，就配了个struts2的filter，启动不起来。

Answer 2

删除 lib包里的
struts2-spring-plugin-2.0.6.jar

Answer 3

是不是引用了空的jar包

Answer 4

filter没有启动成功，我不明白为啥启动struts2的filter却包了spring初始化错误，难道struts2的filter是用spring初始化的，教程中没有提到。

Answer 5

把Spring的包全都去掉
从官方网站上把Struts2download下来，重新配置，不要根据原来带有spring的项目配置

Answer 6

Looks like the Spring listener was not configured for your web app!  
Nothing will work until WebApplicationContextUtils returns a valid ApplicationContext.
You might need to add the following to web.xml:  
  <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>spring listener 没有配置

Answer 7

可以限制index.html了，但是控制台打印了N多个下面的信息，都把前面的信息冲掉了

Answer 8

把lib下的
struts2-spring-plugin-2.0.6.jar去掉。那个是给spring容器用的

  <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

org.apache.struts2.plexus.PlexusObjectFactory.buildInterceptor
lib中有plexus插件  删之。

Answer 11

struts2必须用到的包commons-logging-1.0.4.jar
freeer-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.6.jar
xwork-2.0.1.jar【数据库驱动包】
其它包按照项目用到的东西逐个加。
你lib里无用的包太多了。

Answer 12

尤其是jar名字类似“XXX-plugin-版本号.jar”的，如果不用，一定要删掉。

Answer 14

重新导包了，现在没问题了。第一次碰到因为导包太多造成问题的。sturts2的不会是通过查找类是否存在决定是否导入插件的吧。

Answer 15

额，struts只要5个包就可以了，把不用的都删了

Answer 16

***plugin里面有配置文件，struts2会自动加载。

Answer 17

搞定了？恭喜LZ迈出第一步。
理论上的东西我不清楚，感觉和你14楼说的意思差不多。
自己baidu一下吧。
