Flex整合Spring+hibernate问题集锦

 

今天整合Spring+Hibernate+Flex，遇到了几个问题，现总结如下：

1、问题描述：
   javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/commons/httpclient/UsernamePasswordCredentials
   解决办法：
   缺包，将commons-httpclient-3.0.1.jar包放到lib目录下。
2、问题描述：
   java.lang.NoClassDefFoundError: edu/emory/mathcs/backport/java/util/concurrent/ConcurrentHashMap
   解决办法：
   缺包，将backport-util-concurrent.jar包放到lib目录下。
3、问题描述：
   "FlexConfigurationManager requires a non-null ServletConfig - Is it being used outside a WebApplicationContext?"
   解决办法：
   将Flex的配置文件单独保存为applicationContext-flex.xml，并与spring的其他配置分开，例如：
   创建四个配置文件；
  1) applicationContext.xml
  2) applicationContext-security.xml
  3) applicationContext-services.xml
  4) applicationContext-flex.xml
  其中的applicationContext.xml文件中include 2）、3）文件，而不include4）文件。
  在web.xml的配置文件中，通过ContextLoaderListener来加载applicationContext.xml文件，即2）和3）文件，而通过DispatchServlet来加载applicationContext-flex.xml配置文件。
4、问题描述
  Could not find action or result
  There is no Action mapped for action name amf. - [unknown location]
  解决办法：
   web.xml中对struts的拦截设置与Flex的链接设置有冲突
   将其修改为如下代码即可：
   <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>*.action</url-pattern>
    </filter-mapping>
   
 完整的web.xml的配置文件如下：
