tomcat5换成tomcat7，原本正常的应用报DWR CSRF Security Error错误解决方法

近期在给客户调试应用的时候，遇见一个比较郁闷的问题，原本用tomcat5.0.28,应用一切正常，发现APACHE发布了TOMCAT 7.0.2后，就把自己使用的TOMCAT换成了7.0.2版本，结果发现DWR狂报DWR CSRF Security Erro错误，郁闷中.....后来请教GOOGLE大神，发现需要在web.xml中DWR的配置上加上一段：

 

<init-param>
             <param-name>crossDomainSessionSecurity</param-name>
             <param-value>false</param-value>
      </init-param>
      <init-param>
            <param-name>allowScriptTagRemoting</param-name>
            <param-value>true</param-value>
      </init-param>

  

       

修改成：

<servlet>  
      <servlet-name>dwr-invoker</servlet-name>  
      <servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>  
      <init-param> 
             <param-name>debug</param-name> 
             <param-value>true</param-value> 
      </init-param>

      <init-param>
             <param-name>crossDomainSessionSecurity</param-name>
             <param-value>false</param-value>
      </init-param>
      <init-param>
            <param-name>allowScriptTagRemoting</param-name>
            <param-value>true</param-value>
      </init-param>
</servlet>

 
就好了
