sa token接入redis后，默認(rèn)的key為satoken，雖然可以通過(guò)指定db索引的方式來(lái)區(qū)別不同項(xiàng)目，但是無(wú)法根據(jù)項(xiàng)目來(lái)設(shè)置。

解決方法：

排除SaTokenDaoRedisJackson

spring.autoconfigure.exclude=cn.dev33.satoken.dao.SaTokenDaoRedisJackson

重寫(xiě)SaTokenDaoRedisJackson

import cn.dev33.satoken.SaManager;
import cn.dev33.satoken.config.SaTokenConfig;
import cn.dev33.satoken.dao.SaTokenDaoRedisJackson;
import org.springframework.stereotype.Component;

import java.util.List;

/**
 * sa-token相關(guān)數(shù)據(jù)，使用統(tǒng)一前綴存儲(chǔ)進(jìn)redis
 *  <h3>具體實(shí)現(xiàn)步驟：</h3>
 *  <ul>
 *      <li>
 *          第一步：排除{@link SaTokenDaoRedisJackson}自動(dòng)裝配。如通過(guò)配置文件排除：
 *          {@code
 *           spring:
 *             autoconfigure:
 *               exclude:
 *                 - cn.dev33.satoken.dao.SaTokenDaoRedisJackson
 *          }
 *      </li>
 *      <li>
 *          第二步：重寫(xiě)SaTokenDaoRedisJackson并注冊(cè)進(jìn)spring，參考這里的{@link RedisPrefixSaTokenDaoRedisJackson}
 *      </li>
 *  </ul>
