1.写个工具类SpringContextUtil,实现ApplicationContextAware接口,并完成ApplicationContext初始化。可以调用getBean(String name)方法通过已初始化的ApplicationContext获取spring配置文件中已注册的bean实例。
<pre name="code" class="java">public class SpringContextUtil implements ApplicationContextAware{
private static ApplicationContext applicationContext;
@Override
public void setApplicationContext(ApplicationContext applicationContext){
SpringContextUtil.applicationContext = applicationContext;
}
public static ApplicationContext getApplicationContext(){
return applicationContext;
}
public static Object getBean(String name) throws BeansException{
return applicationContext.getBean(name);
}
}
<bean id="SpringContextUtil" class="com.odchina.micro.util.SpringContextUtil" lazy-init="false"></bean>
<pre name="code" class="html"><bean id="memCacheService" class="com.odchina.micro.common.cache.XMemcachedimpl">
<property name="memcachedClient" ref="memcachedClient" />
<property name="memcachedClientEnhance" ref="memcachedClientEnhance" />
<property name="expireTime" value="108000000" /><!-- 数据过期时间,单位毫秒 -->
<property name="is_updataExp" value="true" />
</bean>
<bean id="memcachedClientEnhance" class="com.odchina.micro.common.cache.MemCachedClientEnhance">
<property name="memcachedClient" ref="memcachedClient" />
</bean>
<bean id="memcachedClient" class="com.danga.MemCached.MemCachedClient" />
3.代码中使用SpringContextUtil获取已注册bean实例
private CacheService memCacheService=(CacheService) SpringContextUtil.getBean("memCacheService");
本文是我结合网上所查资料和自己的项目总结出来的,如有错误,恳请指正。
