在网上看到好多的spring-boot和redis集成的，弄到本地一直报Error resolving template "get", template might not exist or might not be accessible by any of the configured Template Resolvers错误，大概是因为模板什么的没有找到，网上找了好多方法都是不奏效。

然后找其他的方式，找到一个亲测能用的方法。

项目的结构：

        config.setMaxWaitMillis(maxWaitMillis);

}

要说一下的是，如果redis设置了密码启动的时候要用 redis-server.exe redis.window.conf 启动，用来启用密码。
