DWR请求中用过滤器验证session
要解决dwr请求时，统一对session进行管理，在网上搜了一下，它有自己的过滤器，狂喜！
?
DwrFilter.java
?
public class DwrFilter implements AjaxFilter {private static final Log logger = LogFactory.getLog(DwrFilter.class);public Object doFilter(Object object, Method method, Object[] arr,AjaxFilterChain chain) throws Exception {//DWR方法session同步HttpServletRequest request = WebContextFactory.get().getHttpServletRequest();HttpSession session = request.getSession();SessionAgentTool.setSession(new SessionContext(session));//拦截调用方法String methodName = method.getName();logger.info("拦截DWR目标方法：" + methodName);Object obj = chain.doFilter(object, method, arr);logger.info("DWR目标方法 " + method.getName() + " 执行结束");return obj;}}?
dwr.xml添加以下代码
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://www.getahead.ltd.uk/dwr/dwr20.dtd"><dwr> <allow> ...... <filter class="com.wingon.core.filter.DwrFilter"></filter> </allow></dwr>

就这两步，OK了。
