springboot3+vue3（八）Redis 基础使用 -- 登录优化

Redis基础使用

1、在pom文件中添加Redis坐标

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

redis坐标

2、在yml中添加redis的配置信息

3、在测试类中来编写

@SpringBootTest //如果在测试类上添加了这个注解，那么将来单元测试方法执行之前，会先初始化Spring容器
public class RedisTest {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    @Test
    public void testset(){
        //往redis中存储一个键值对 StringRedisTemplate
        ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();

        //存储至Redis
        operations.set("username","zhangsan");
        operations.set("id","1",10, TimeUnit.MINUTES); //key value timeout-过期时间 unit-过期时间单位TimeUnit枚举
    }

    @Test
    public void testget(){
        ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
        //从Redis中获取数据
        System.out.println(operations.get("username"));
    }

    @Test
    public void testdelete(){
        ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
        //从Redis中删除对应的键值
        operations.getOperations().delete("username");
    }
