导依赖　

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

配置数据源在（.yml中）

spring:
      redis:
        host: 192.168.110.10
        port: 6379

测试类

@Autowired
    private RedisTemplate redisTemplate;
    @Test
    public void testRedis(){
        //redis存入数据
        redisTemplate.opsForValue().set("hi","hello");
        //redis去除数据
        String str=(String) redisTemplate.opsForValue().get("hi");
        System.out.println(str);
        MUser mUser= new MUser();
        mUser.setId(1);
        mUser.setName("张三");
        mUser.setUsername("你好呀");
        mUser.setPassword("123456");
        redisTemplate.opsForValue().set("user",mUser);
        MUser user = (MUser)redisTemplate.opsForValue().get("user");
        System.out.println(user);
    }
