baseservlet.java

一个基于ext的ajax小例子

/**

 */
package com.myext.servlet;

import javax.servlet.http.HttpServlet;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

/**
 * @author Administrator
 *
 */
public class BaseServlet extends HttpServlet {

	/**  serialVersionUID */
	private static final long serialVersionUID = 1L;

	/**
	 * @param beanName
	 * @return
	 */
	public Object getBean(String beanName) {
		WebApplicationContext applicationContext = WebApplicationContextUtils
				.getRequiredWebApplicationContext(getServletContext());
		return applicationContext.getBean(beanName);
	}
}
