　　2.登陆

2-1controller创建登陆方法

　　步骤://1. openid去和数据库里的数据匹配

　　　　2. 设置token至redis:[

使用redis步骤:

1.引入依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

　　2.在controller里面引入

1
2
@Autowired
    private StringRedisTemplate redisTemplate;

　　3.在方法里

1
redisTepla.opsForValue().set("abc","1111111");//告诉redic调用并set key-value

　　

 

]

　　　　/3. 设置token至cookie
