SpringBoot使用redis缓存读取mysql数据到redis进行存储出现乱码

1--利用SpringBoot读取mysql数据进行在页面显示正确：

2-将读取的mysql数据存入reids缓存：存入的是3号数据库；

   

 

进行redis时缓存时，发现存储在redis中的key不是设置的string值，前面还多出了许多类似\xac\xed\x00\x05t\x00这种字符串，如下

pring-data-redis的RedisTemplate<K, V>模板类在操作redis时默认使用JdkSerializationRedisSerializer来进行序列化，如下

private boolean enableDefaultSerializer = true;
private RedisSerializer<?> defaultSerializer = new JdkSerializationRedisSerializer();
private RedisSerializer keySerializer = null;
private RedisSerializer valueSerializer = null;
private RedisSerializer hashKeySerializer = null;
private RedisSerializer hashValueSerializer = null;
 

解决办法：进行序列化：

private RedisTemplate redisTemplate;

@Autowired(required = false)
public void setRedisTemplate(RedisTemplate redisTemplate) {
    RedisSerializer stringSerializer = new StringRedisSerializer();
    redisTemplate.setKeySerializer(stringSerializer);
    redisTemplate.setValueSerializer(stringSerializer);
    redisTemplate.setHashKeySerializer(stringSerializer);
    redisTemplate.setHashValueSerializer(stringSerializer);
    this.redisTemplate = redisTemplate;
}
 

显示结果：完成！
