1.在基于 Spring 的 web 项目中,我们可以随时随地获取到当前请求,获取方式就是下面给出的代码:
HttpServletRequest req = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
String code = req.getParameter("code");
2.spring项目一启动就加载某些操作的代码示例:
@Component
public class DicCacheManage implements ApplicationContextAware {
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
log.info("=======开始加载字典缓存======");
DicMap.initDicts(applicationContext);
log.info("=======结束加载字典缓存======");
}
}
