实现方法:在dwr每个方法调用前拦截验证权限
AjaxFilterChain chain) throws Exception {
WebContext ctx = WebContextFactory.get();
HttpServletRequest request = ctx.getHttpServletRequest();
HttpSession session = request.getSession();
String flag =(String) session.getAttribute("flag");
if(null == flag){
System.out.println("session验证失败");
return "session_error";
}
String
methodName=method.getName();
if(!CheckLimit(methodName)){
System.out.println("权限验证失败");
return "limit_error";
}
<allow> <create javascript="TermManager" creator="spring" scope="application"> <param name="beanName" value="TermManager"></param> </create>
<filter class="net.gkyh.util.DWRFilter"></filter>
</allow>

1.实现拦截器(需dwr2.0以上版本)
package net.gkyh.util;
import java.lang.reflect.Method;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.directwebremoting.AjaxFilter;
import org.directwebremoting.AjaxFilterChain;
import org.directwebremoting.WebContext;
import org.directwebremoting.WebContextFactory;
public class DWRFilter implements AjaxFilter{
public Object doFilter(Object object,Method method,Object[] arr,
//获取session
Object obj=chain.doFilter(object,method,arr);
System.out.println("目标方法"+method.getName()+"执行结束");
return obj;
}
}
