springboot连接docker的redis注意事项

1、虚拟机配置

redis配置保护模式关闭：no

配置bind:0.0.0.0  ,  代表ip可以访问，如果是默认的127.0.0.1，代表仅自己本机

注意：将daemonize yes注释起来或者 daemonize no设置，因为该配置和docker run中-d参数冲突，会导致容器一直启动失败

 

2、springboot配置

基本属于默认配置

 项目添加配置类：

redisTemplate.opsForValue().set("name","lucy"); //从redis获取值 String name = (String)redisTemplate.opsForValue().get("name");

 注意：获取数据时的类型，因为配置类的相关配置，返回的类型会自动的装换如：bank1的数据类型是json

结果：自动根据定义的类装配成对象，自己类型强转要注意
