redis的使用（五）spring boot 整合redis（lettuce）

lettuce和jedis的比较 Lettuce相较于Jedis有哪些优缺点？ - 知乎

1. 依赖

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-redis -->

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-data-redis</artifactId>

<version>2.4.0</version>

</dependency>

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 -->

<dependency>

<groupId>org.apache.commons</groupId>

<artifactId>commons-pool2</artifactId>

<version>2.4.2</version>

</dependency>

2.配置文件

redis:

  database: 0

  host: 

  port: 6379

  password: 

  lettuce:

    pool:

      max-active: 8

      max-wait: 1

      max-idle: 8

      min-idle: 0

3. 配置类

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate redisTemplate(LettuceConnectionFactory connectionFactory) {
        RedisTemplate template = new RedisTemplate();
        RedisSerializer<String> redisSerializer = new StringRedisSerializer();
        template.setConnectionFactory(connectionFactory);
        // key序列化方式
        template.setKeySerializer(redisSerializer);
        // value序列化
        template.setValueSerializer(redisSerializer);
        // value hashmap序列化
        template.setHashValueSerializer(redisSerializer);
        return template;
    }
    @Bean
    public StringRedisTemplate stringRedisTemplate(LettuceConnectionFactory connectionFactory) {
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory(connectionFactory);
        return stringRedisTemplate;
    }
}
