我查了网上说没有struts2-spring-plugin-2.2.1.jar 但是我有

Answer 1

Caused by: Unable to load file:/D:/JSP配置/apache-tomcat-7.0.6/webapps/ssh/WEB-INF/classes/struts.xml - [unknown location]
发一下你的web.xml配置看看

Answer 2

你可以用MyEclipse自带的功能 导入jar包导入顺序spring -->hibernate --> struts2
hibernate的包要在spring之后导入struts2-spring-plugin-2.2.1.jar 是必须的

Answer 3

WEB.XML
<?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">    <display-name>Struts Blank</display-name>    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>    <filter-mapping>
        <filter-name>struts2</filter-name>

    </filter-mapping>
   
     <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list></web-app>

Answer 4

你好像是少陪了spring的两种配置
<context-param>
  <param-name>contextConfigLocation</param-name> 
  <param-value>classpath:applicationContext-*.xml</param-value> 
</context-param>
还有监听器<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener>要是要用汉语的的话最好加上过滤器
<filter>
  <filter-name>SetCharacterEncoding</filter-name> 
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 
 <init-param>
  <param-name>encoding</param-name> 
  <param-value>utf-8</param-value> 
 </init-param>
  </filter>
<filter-mapping>
  <filter-name>SetCharacterEncoding</filter-name> 
  <url-pattern>/*</url-pattern> 
</filter-mapping>

Answer 5

当我去掉
 <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
   
就没有什么问题 开始我也加了监听器 但是也报错

Answer 6

这是我的web.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>
<!-- Encording配置 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 结束 -->
<!-- Open session in view开始 --> <filter>
<filter-name>openSessionInView</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>

<param-value>AUTO</param-value>    
</init-param>
</filter> <filter-mapping>
<filter-name>openSessionInView</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- Open Session in view结束 -->
<!-- struts配置 -->
<filter>
<filter-name>struts2</filter-name>

</filter> <filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Struts结束 --> <!-- spring 配置 -->

<param-value>classpath:beans.xml</param-value>
</context-param> <!-- spring 结束 -->
</web-app>

Answer 7

怎么还在web.xml里面开始session啊，不是在hibernate的配置里就可以通过sessionFactory来开启吗

Answer 8

LZ，你这是整合struts的时候出错了，那边配置都应该没什么问题，我问题出在你的web.xml这里，#6楼的老兄的也可以借鉴一下啊！或者你吧我那两句加进去试试！

Answer 9

Exception starting filter struts2
Unable to load configuration. - [unknown location]
严重: Error filterStart
2010-3-19 9:30:14 org.apache.catalina.core.StandardContext startInternal
严重: Context [/ssh] startup failed due to previous errors
报的这两句错是关键！刚刚没仔细看下面，原来你没用hibernate的那种，是用的jdbc，照着这两句去找错，应该能找出来吧！

Answer 10

会不会是少加了Lib包呀
或者有冲突
