<!-- redis -->
        <dependency>

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

2.config


@Configuration
@ConditionalOnProperty(value="redis.config.host")
public class RedisConfig extends CachingConfigurerSupport {

    @Autowired
    private RedisBean redisBean;

    @Bean
    public RedisService gerRedisService(){
        return new RedisService(redisTemplate(redisConnectionFactory()));
    }

    @Bean
    public JedisConnectionFactory redisConnectionFactory() {
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setHostName(redisBean.getHost());
        factory.setPort(redisBean.getPort());

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

    }
}

3.application.yml配置
*若设置密码，需在redis.windows-service.conf文件中修改requirepass 属性

redis:
  config:
    host: 127.0.0.1
    port: 6379
    timeout: 1000
   # password: 123456
    minIdle: 0
    maxIdle: 10
    maxActive: 200
    maxWait: -1
