springboot訪問redis報這個錯誤：
org.springframework.dao.InvalidDataAccessApiUsageException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password.

查了半天說是訪問redis的參數設置問題，配置文件的 timeout 參數設置爲0 同時配置testOnReturn，testWhileIdle，testOnBorrow爲true 但是試了沒有解決問題，其實我忽略了報錯開始的信息：
1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.
人家redis已經給了三個解決方法：SET protected-mode no 說的明明的，查了一下資料這個如下
Redis3.2版本後新增protected-mode配置，默認是yes，即開啓。protected-mode設置爲不同值時的效果如下：
protected-mode值 效果
no 關閉protected-mode模式，此時外部網絡可以直接訪問
yes 開啓protected-mode保護模式，需配置bind ip或者設置訪問密碼
想要在外部訪問服務器中的Redis 除了需要設置 protected-mode no ，還需將 redis.conf 文件中的bind:127.0.0.1語句註釋
開發一直使用的是redis 3.0 這次服務器上用了redis 5.0.7就出現這個問題
將配置文件中protected-mode設置爲no 問題解決，看來以後遇到問題要仔細看報錯日誌
