springboot data redis 优雅的存取java实体类对象

• • 前言
  • 项目结构
  • 配置类：（实现redis的序列化）
  • • FastJsonRedisSerializer.java
    • RedisConfig.java
  • 实体类 UserVO.java
  • util
  • • RedisObjUtil.java
  • 测试类
  • 运行结果

RedisTemplate是spring封装的操作redis的接口，使用起来很方便，但也有很多坑，比如存储javabean类。这里将使用fastjson实现序列化。非常滴人性！话不多说直接上demo

        return (T) JSON.parseObject(str, clazz);
