struts2和CKFinder的整合(java版)

### 原因： ###

默认web.xml配置

<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>

站点所有请求都要经过struts2过滤器，即CKFinder相关请求也会被struts2拦截，导致请求没有经过CKFinder配置的servlet。

<servlet> 
            <servlet-name>ConnectorServlet</servlet-name> 
            <servlet-class>com.ckfinder.connector.ConnectorServlet</servlet-class>
            <init-param> 
                <param-name>XMLConfig</param-name> 
                <param-value>/WEB-INF/ckfinder.xml</param-value> 
            </init-param> 
            <init-param> 
                <param-name>debug</param-name> 
                <param-value>false</param-value> 
            </init-param> 
            <load-on-startup>1</load-on-startup> 
        </servlet> 
        <servlet-mapping>
            <servlet-name>ConnectorServlet</servlet-name> 
            <url-pattern>/ckfinder2.4/core/connector/java/connector.java </url-pattern> 
        </servlet-mapping>

## 解决办法： ##

自己实现struts2过滤器，判断是否CKFinderde 请求，如果是则放行，否则默认struts2的方式继续往下走。部分代码如下：

import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;
    
    public class MyStrutsInterceptor extends StrutsPrepareAndExecuteFilter {
        public void doFilter(ServletRequest req, ServletResponse res,
                FilterChain chain) throws IOException, ServletException {
            HttpServletRequest request = (HttpServletRequest) req;
            String URI = request.getRequestURI();
        
            String[] ckfarr = URI.split("/ckfinder2.4/core/connector/java/*/");
            int arrayLen = ckfarr.length;
            if (arrayLen >= 2) {
                chain.doFilter(req, res);
            } else {
                super.doFilter(req, res, chain);
            }
    
        }
    
    }
