OGNL会执行执行安全检测,但是并不被GAE所支持,解决方法是创建一个监听器,将安全检查处理器置空

 

 

 

OgnlRuntime.setSecurityManager(null);

 

 

web.xml添加

 

<listener>
		<listener-class>com.llx.gps.listener.Struts2ListenerOnGAE</listener-class>
	</listener>
package com.llx.gps.listener;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.http.HttpSessionAttributeListener;
import javax.servlet.http.HttpSessionBindingEvent;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;

import ognl.OgnlRuntime;

public class Struts2ListenerOnGAE implements ServletContextListener, HttpSessionListener, HttpSessionAttributeListener {

	public void contextInitialized(ServletContextEvent sce) {
		OgnlRuntime.setSecurityManager(null);
	}

	@Override
	public void contextDestroyed(ServletContextEvent arg0) {
		// TODO Auto-generated method stub

	}

	@Override
	public void sessionCreated(HttpSessionEvent arg0) {
		// TODO Auto-generated method stub

	}

	@Override
	public void sessionDestroyed(HttpSessionEvent arg0) {
		// TODO Auto-generated method stub

	}

	@Override
	public void attributeAdded(HttpSessionBindingEvent arg0) {
		// TODO Auto-generated method stub

	}

	@Override
	public void attributeRemoved(HttpSessionBindingEvent arg0) {
		// TODO Auto-generated method stub

	}

	@Override
	public void attributeReplaced(HttpSessionBindingEvent arg0) {
		// TODO Auto-generated method stub

	}

}
