什么问题啊？我用的myeclipse的tomcat;struts2包里面只有基本的6个jar包。

Answer 1

You might need to add the following to web.xml: 
  <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
17:51:26,633 ERROR org.apache.struts2.dispatcher.Dispatcher:38 - Dispatcher initialization failed
java.lang.NullPointerException
很明显的问题啊。。
在你的web.xml文件中添加listener
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

Answer 2

项目里面不用Spring，也要加那个？

Answer 3

检查struts2的struts.xml配置文件中是不是有<constant name="struts.objectFactory" value="spring" />   或者struts.properties中是否有struts.objectFactory=spring  

Answer 4

没有
这个是xml<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
   
      <filter>
        <filter-name>struts2</filter-name>
      
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>  <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
 
    </web-app>

Answer 5

web.xml有问题啊，如果加了监听器，肯定要报错的，你项目里面没有那个包吧

Answer 6

 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
这个是Struts的filter啊

Answer 7

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>这个是Struts的filter啊

Answer 8

lz说没用spring，但我怀疑lz加了与spring相关的jar包了，lz，把你的jar包贴出来看一下吧

Answer 9

楼主。你是用的自动编译么？重新编译次再启动试试。报是报说SPRING配置问题 需要加
Looks like the Spring listener was not configured for your web app!
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

Answer 10

You might need to add the following to web.xml:  
  <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
兄弟，spring还没配置正确就，先别整合啦！！

Answer 11

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>
然后，将struts-spring-plugin.jar加入到项目的lib目录下，就可以了。struts-spring-plugin.jar中包含有整合所需要的struts-default.xml文件，其中就有<constant name="struts.objectFactory" value="spring" />语句。

Answer 12

这个是hibernate的xml,是不是这个有错误？
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration> <session-factory> <!-- Database connection settings -->
