SpringBoot2.0整合Redis

依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
springboot2.0的redis整合包多出lettuce连接池，需要commons-pool2，所以项目pom依赖要添加commons-pool2

<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
<version>2.6.0</version>
</dependency>
1、配置类
@Configuration
public class RedisConfig extends CachingConfigurerSupport {

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {

    RedisTemplate<String, Object> template = new RedisTemplate<>();

    RedisSerializer<String> redisSerializer = new StringRedisSerializer();

    Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
    ObjectMapper om = new ObjectMapper();
    om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
    om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
    jackson2JsonRedisSerializer.setObjectMapper(om);

    template.setConnectionFactory(factory);
    //key序列化方式
    template.setKeySerializer(redisSerializer);
    //value序列化
    template.setValueSerializer(jackson2JsonRedisSerializer);
    //value hashmap序列化
    template.setHashValueSerializer(jackson2JsonRedisSerializer);

    return template;
}

@Bean
public CacheManager cacheManager(RedisConnectionFactory factory) {
    RedisSerializer<String> redisSerializer = new StringRedisSerializer();
    Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

    //解决查询缓存转换异常的问题
    ObjectMapper om = new ObjectMapper();
    om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
    om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
    jackson2JsonRedisSerializer.setObjectMapper(om);

    // 配置序列化（解决乱码的问题）,过期时间30秒
    RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
            .entryTtl(Duration.ofSeconds(30))
            .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer))
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer))
            .disableCachingNullValues();

    RedisCacheManager cacheManager = RedisCacheManager.builder(factory)
            .cacheDefaults(config)
            .build();
    return cacheManager;
}

}
2、yml配置
spring:
redis:
database: 0
host: 127.0.0.1
jedis:
pool:
#最大连接数据库连接数,设 0 为没有限制
max-active: 8
#最大等待连接中的数量,设 0 为没有限制
max-idle: 8
#最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。
max-wait: -1ms
#最小等待连接中的数量,设 0 为没有限制
min-idle: 0
lettuce:
pool:
max-active: 8
max-idle: 8
max-wait: -1ms
min-idle: 0
shutdown-timeout: 100ms
password: ''
port: 6379
3、使用
1）StringRedisTemplate，存储字符串类型
//控制层调用
@Autowired
private StringRedisTemplate stringRedisTemplate;
2）、RedisTemplate, 存储对象类型
//控制层调用
@Autowired
private RedisTemplate redisTemplate;
