echo编辑整理

该文章是接上一篇文章《Redis整合SpringBoot示例》的后续，操作用例代码比较多，这里展示核心代码所占篇幅很多，所以单独抽出来写

zset类型在SpringBoot中的使用代码如下

package com.example.echo.redis;

import org.junit.Test;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ZSetOperations;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.HashSet;
import java.util.Set;
