Action

@Controller
@Scope("prototype")//作为spring 多实例
public class UserAction {@Autowiredprivate RedisUtil redisUtil;@Autowiredprivate UserService userService;private User user;/*** @return* @desc 不想写页面了*/public String saveUser() {userService.saveUser(user);return "SUCCESS";}/*** @return* @desc 如果redis中有就取出 没有从数据库取出存入redis中*/public String queryUser() {String key_id = "key_" + 1;boolean key = redisUtil.hasKey(key_id);if (key) {System.out.println("redis");User user = (User) redisUtil.get(key_id);System.out.println(user.toString());return "2";} else {System.out.println("sjk");user = userService.queryUser();redisUtil.set(key_id, user);return "1";}}//set and get
}

完事了

只是一次简单的整合。查询的时候 redis中没有就去数据库查找，有就redis拿出来。
