最全的 基于 RedisTemplate 封装的 RedisUtils 工具类

SpringUtils.java  获取 RedisTemplate bean 对象使用

/*** spring工具类 方便在非spring管理环境中获取bean* * @author Lion Li*/
@Component
public final class SpringUtils implements BeanFactoryPostProcessor
{/** Spring应用上下文环境 */private static ConfigurableListableBeanFactory beanFactory;@Overridepublic void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException{SpringUtils.beanFactory = beanFactory;}/*** 获取对象** @param name* @return Object 一个以所给名字注册的bean的实例* @throws org.springframework.beans.BeansException**/@SuppressWarnings("unchecked")public static <T> T getBean(String name) throws BeansException{return (T) beanFactory.getBean(name);}/*** 获取类型为requiredType的对象** @param clz* @return* @throws org.springframework.beans.BeansException**/public static <T> T getBean(Class<T> clz) throws BeansException{T result = (T) beanFactory.getBean(clz);return result;}}
