1.实现接口BeanPostProcessor

import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.BeansException;import org.springframework.beans.factory.config.BeanPostProcessor;import com.baidu.bainuo.weblab.api.impl.AbstractEvalEngine;/** * 启动时,spring加载 bean 并刷新 cache从 redis 中 * @author gaoming03 */public class CacheBeanPostProcessor implements BeanPostProcessor {    protected final Logger log = LoggerFactory.getLogger(getClass());    @Override //类实例化之前    public Object postProcessAfterInitialization(Object obj, String arg1) throws BeansException {        try {   //当实例化 AbstractEvalEngine后,执行.            if (obj instanceof AbstractEvalEngine) {               String flushResult= ((AbstractEvalEngine) obj).flushAll("0");// 加载完整 redis 配置到 cache               log.info("cache flushAll result-->{}", flushResult);            }        } catch (Exception e) {            log.error("ex={}", e);        }        return obj;    }    @Override //类实例化之后    public Object postProcessBeforeInitialization(Object arg0, String arg1) throws BeansException {        return arg0;    }}

2.配置 bean

<!-- 初始化 bean,完全 cache 同步 --><bean id="cacheBeanPostProcessor" class="com.baidu.bainuo.weblab.api.cache.CacheBeanPostProcessor" />

这样就行了
