本文主要是介绍SpringBoot整合redis，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

​

一、引入依赖

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
     <groupId>org.apache.commons</groupId>
     <artifactId>commons-pool2</artifactId>
</dependency>

二、配置文件application.yml

spring:
  redis:
    # redis 服务器地址
    host: 127.0.0.1
    # redis 端口
    port: 6379
    # redis 数据库索引(默认为0)
    database: 0
    # 连接超时时间
    timeout: 18000
    # 连接池
    lettuce:
      pool:
        # 连接池最大连接数，使用负值表示没有限制
        max-active: 20
        # 连接池最大阻塞等待时间，使用负值表示没有限制
        max-wait: -1
        # 连接池最大空闲连接
        max-idle: 5
        # 连接池最小空闲连接
        min-idle: 0

三、redis配置类

@EnableCaching
@Configuration
public class RedisConfig extends CachingConfigurerSupport {

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

        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper mapper = new ObjectMapper();
        mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.serialize(mapper);
        StringRedisSerializer redisSerializer = new StringRedisSerializer();
        // key采用String的序列化方式
        redisTemplate.setKeySerializer(redisSerializer);
        // value序列化方式采用jackson
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // hash的key也采用String的序列化方式
        redisTemplate.setHashKeySerializer(redisSerializer);
        // hash的value序列化方式采用jackson
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {

        RedisSerializer<String> redisSerializer = new StringRedisSerializer();
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        // 解决查询缓存转换异常问题
        ObjectMapper mapper = new ObjectMapper();
        mapper.setVisibility(PropertyAccessor.ALL,JsonAutoDetect.Visibility.ANY);
        mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(mapper);
        // 配置序列化（解决乱码问题），过期时间600秒
        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofSeconds(600))
                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer))
                .disableCachingNullValues();
        RedisCacheManager cacheManager = RedisCacheManager.builder(redisConnectionFactory)
                .cacheDefaults(redisCacheConfiguration)
                .build();
        return cacheManager;

    }
}

四、测试一下

@RestController
@RequestMapping("/redisTest")
public class RedisController {
    @Autowired
    private RedisTemplate redisTemplate;

    @GetMapping("/redis")
    public String redisTest() {
        redisTemplate.opsForValue().set("name","张三");
        return (String) redisTemplate.opsForValue().get("name");
    }
}

持续学习中，更新。。。
