SpringBoot整合Redis在可视化工具乱码问题，以及常用的api

 pom依赖：

 <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.1.RELEASE</version>
    <relativePath/>
 </parent>

<dependencies>
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-data-redis</artifactId>
      </dependency>
</dependencies>  

yml配置：

 spring:
   redis:
     host: 127.0.0.1

配置类：

/**
 * @author GongXincheng
 * @since 2019-09-26 13:36
 */
@Configuration
public class RedisConfigBean {

    /**
     * redis 防止key value 前缀乱码.
     *
     * @param factory redis连接 factory
     * @return redisTemplate
     */
    @Bean(name = "redisTemplate")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        template.setHashKeySerializer(new GenericJackson2JsonRedisSerializer());
        template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        template.afterPropertiesSet();
        return template;
    }

}

常用api：

stringRedisTemplate.opsForValue().set("test", "100",60*10,TimeUnit.SECONDS);//向redis里存入数据和设置缓存时间
stringRedisTemplate.opsForValue().get("test") //根据key获取缓存中的val
stringRedisTemplate.boundValueOps("test").increment(-1); //val做-1操作
stringRedisTemplate.boundValueOps("test").increment(1); //val +1
stringRedisTemplate.getExpire("test") //根据key获取过期时间
stringRedisTemplate.getExpire("test",TimeUnit.SECONDS) //根据key获取过期时间并换算成指定单位
stringRedisTemplate.delete("test"); //根据key删除缓存
stringRedisTemplate.hasKey("546545"); //检查key是否存在，返回boolean值
stringRedisTemplate.expire("red_123",1000 , TimeUnit.MILLISECONDS); //设置过期时间
stringRedisTemplate.opsForSet().add("red_123", "1","2","3");　　//向指定key中存放set集合
stringRedisTemplate.opsForSet().isMember("red_123", "1")　　//根据key查看集合中是否存在指定数据
stringRedisTemplate.opsForSet().members("red_123");　　//根据key获取set集合
