Answer 1

在配一个类时,可能依赖另外一个类,但是你并没有配,对吗?
具体可以看下你的.xml配置文档...good luck!~

Answer 2

import 解析的类没有，No bean named '' is defined 说明tomacat没有解析到需要的类，查查类名称是否一致

Answer 3

你的struts-config.xml中其中一个action没有配置name,也就是formbean

Answer 4

我在web.xml文件里面添加了acegi的配置，去掉acegi配置可以正常打开index.jsp页面。只有加上acegi的配置，进入项目就报上面的错误。
下面是web.xml里面的acegi配置：
  <filter>
    <filter-name>Acegi Filter Chain Proxy</filter-name>
    <filter-class>org.acegisecurity.util.FilterToBeanProxy</filter-class>
    <init-param>
      <param-name>targetClass</param-name>
      <param-value>org.acegisecurity.util.FilterChainProxy</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>Acegi Filter Chain Proxy</filter-name>
    <url-pattern>*.do</url-pattern>
  </filter-mapping>
  <filter-mapping>
<filter-name>Acegi Filter Chain Proxy</filter-name>
<url-pattern>*.jsp</url-pattern>
  </filter-mapping>
  <filter-mapping>
<filter-name>Acegi Filter Chain Proxy</filter-name>
<url-pattern>/j_acegi_security_check</url-pattern>
  </filter-mapping>  <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <listener>
    <listener-class>org.acegisecurity.ui.session.HttpSessionEventPublisher</listener-class>
  </listener>

Answer 5

applicationContext-acegi-security.xml的配置：

Answer 6

找找是不是类名不对啊，如XxxAction,XxxForm

Answer 7

CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
    PATTERN_TYPE_APACHE_ANT
            /**=httpSessionContextIntegrationFilter,logoutFilter,authenticationProcessingFilter,
            anonymousProcessingFilter,exceptionTranslationFilter,filterInvocationInterceptor不能换行，你的错误是换行所致……

Answer 8

哇 我最近也在学ACEGI 也是这个问题 书上的例子就是换行的 咱就跟着换了 难道真是换行问题吗 如果真的是 那太损里 还得多谢楼上之人兄提醒哦

Answer 9

web.xml 没配置它也会报这错误！
<context-param>
     <param-name>contextConfigLocation</param-name>
     <param-value>/WEB-INF/applicationContext.xml,/WEB-INF/acegi-config.xml</param-value>
</context-param>
