工具类用于获取bean,

applicationContext.xml

工具类:

package com.hna.hka.rmc.common.util;

import javax.servlet.ServletContext;

import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.web.context.ServletContextAware;

/**

• 从Spring获取容器中的对象
• @author weiyuan

• */ public class SpringContextUtil implements ApplicationContextAware, ServletContextAware {

  private static ApplicationContext applicationContext; // Spring上下文对象.静态变量,可以在任何时间、任何地点以任何代码取出ApplicaitonContext. 

  private static ServletContext servletContext;// 注入 系统上下文对象

  Log log = LogFactory.getLog(SpringContextUtil.class); /**

  • 实现ApplicationContextAware接口的回调方法，设置上下文环境。
  • @param applicationContext
  • @throws BeansException */ public void setApplicationContext(ApplicationContext applicationContext) { log.debug(" com.hna.hka.rmc.common.util.SpringContextUtil setApplicationContext "+applicationContext); SpringContextUtil.applicationContext = applicationContext; }

  /**

  • @return ApplicationContext */ public static ApplicationContext getApplicationContext() { return applicationContext; }

  /**

  • 获取对象
  • @param name
  • @return Object 以给定名称注册的bean的实例
  • @throws BeansException */ public static Object getBean(String name) throws BeansException { return applicationContext.getBean(name); }

  /**

  • 功能 : 实现 ServletContextAware接口,由Spring自动注入 系统上下文对象

  • **/ public void setServletContext(ServletContext servletContext) { SpringContextUtil.servletContext = servletContext; }

  /**

  • @return ServletContext */ public static ServletContext getServletContext() { return servletContext; } }

java调用:

private Template template = (Template) SpringContextUtil.getBean("Template");
