springboot 2.x整合redis

引入redis依赖

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

设置连接redis的配置

Redis配置

spring.redis.port=6379
spring.redis.host=your host
spring.redis.password=your password

配置redis连接

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 使用Jackson2JsonRedisSerialize 替换默认的jdkSerializeable序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 设置value的序列化规则和 key的序列化规则
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

开始使用

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootRedisApplicationTests {

    @Autowired
    private RedisTemplate redisTemplate;
    @Test
    public void contextLoads() {

        redisTemplate.opsForValue().set("name","hansn");
        String s = (String) redisTemplate.opsForValue().get("name");
        System.out.println(s);

        //设置过期时间
        redisTemplate.opsForValue().set("name1","hansn007",10,TimeUnit.MINUTES);
        String s1 = (String) redisTemplate.opsForValue().get("name1");
        System.out.println(s1);
    }

}
