只让过滤器对加有.action后缀的路径有效。
2.自定义一个继承StrutsPrepareAndExecuteFilter的过滤器，将配置换成自己自定义的过滤器。（如果大项目改.action不实际，推荐此法）
对于链接多个文件（如：fckeditor和struts2的结合）
package com.olympus.sapg.smtinnovation.util.method;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;
public class FCKFilter extends StrutsPrepareAndExecuteFilter
{
public void doFilter(ServletRequest req,ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
String URI = request.getRequestURI();
String[] uriArray = URI.split("/fckeditor/editor/filemanager/connectors/");
int arrayLen = uriArray.length;
if (arrayLen >= 2) {
chain.doFilter(req, res);
}else{
super.doFilter(req, res, chain);
}
}
}
单个链接的过滤器：
public class ExtendStrutsFilter extends StrutsPrepareAndExecuteFilter {
@Override
public void doFilter(ServletRequest req, ServletResponse res,FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
//不过滤的url,可以自行添加
if ("/demo/fileupload".equals(request.getRequestURI())) {
//System.out.println("使用自定义的过滤器");
chain.doFilter(req, res);
}else{
//System.out.println("使用默认的过滤器");
super.doFilter(req, res, chain);
}
}
}
web.xml文件：
struts2 com.filter.ExtendStrutsFilter struts2 /*
