1.安装包

EasyCaching.Core
EasyCaching.Redis
EasyCaching.Serialization.MessagePack
这里是以1.4.0为例

2.服务注册

netcore3.0,5.0是在startup，net6是在program设置

builder.Services.AddEasyCaching(option =>
{
    option.UseRedis(t =>
    {
    	//当需要连接redis集群时，只需要连接一个redis，其他会自动关联上，只需要 t.DBConfig.Endpoints.Add(new EasyCaching.Core.Configurations.ServerEndPoint("服务器地址",6379) )
        //43.138.88.44服务器地址，6379端口
        t.DBConfig.Endpoints.Add(new EasyCaching.Core.Configurations.ServerEndPoint("服务器地址",6379) );
        //连接那个数据库
        t.DBConfig.Database = 1;
        //数据库密码
        t.DBConfig.Password = "服务器密码";
    });
});

3.使用

Person辅助类

    public class Person
    {
        public string Name { get; set; }
        public string Sex { get; set; }
    }
