Redis整合SpringBoot

一、SpringBoot整合Redis

1.1 导入Maven

<!-- 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>2.6.7</version>
</dependency>

1.2 配置Redis连接

spring:
  redis:
    client-type: jedis #客户端类型
    host: localhost
    port: 6379
    jedis:
      pool:
        enabled: true
        max-active: 20 # 连接池最大连接数（使用负值表示没有限制）
        max-idle: 10 # 连接池中的最大空闲连接
        min-idle: 5 # 连接池中的最小空闲连接
        max-wait: 1000ms # 连接池最大阻塞等待时间（使用负值表示没有限制）

1.3 定制Redis序列化机制

@Configuration
public class RedisConfig {
    /**
     * redis序列化配置
     *
     * @param redisConnectionFactory redis连接工厂
     * @return redisTemplate
     */
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        // 配置redisTemplate
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        // 设置序列化
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        // key序列化
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        // value序列化
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // Hash key序列化
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        // Hash value序列化
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        //开启事务支持
//        redisTemplate.setEnableTransactionSupport(true);
        return redisTemplate;
    }
}

二、整合Redission

2.1 导入Maven

<!--引入redisso客户端依赖-->
<dependency>
    <groupId>org.redisson</groupId>
    <artifactId>redisson</artifactId>
    <version>3.17.0</version>
</dependency>

2.2 自定义配置Redisson

@Configuration
public class RedissionConfig {
    @Bean(destroyMethod = "shutdown")
    public RedissonClient redisson() throws IOException {
        Config config = new Config();
        //单节点模式
        //Redis url should start with redis:// or rediss:// (for SSL connection)
        //可以用"rediss://"来启用SSL连接
        config.useSingleServer()
                .setAddress("redis://127.0.0.1:6379");
        return Redisson.create(config);
    }
}
