自定义拦截器

package 域名rceptor;

import 域名域名onInvocation;
import 域名域名rceptor;
import 域名域名Action;

public class LoginInterceptor  implements Interceptor{

	@Override
	public void destroy() {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void init() {
		// TODO Auto-generated method stub
		
	}

	@Override
	public String intercept(ActionInvocation invocation) throws Exception {
		   域名tln("进入拦截器");
		   // 对LoginAction不做该项拦截  
	        Object action = 域名ction();  
	        if (action instanceof UserAction) {  
	            域名tln("exit check login, because this is login action.");  
	            return 域名ke();  
	        }  
		
		return 域名ke();
	}
	

}
