解决Spring Boot 使用RedisTemplate 存储键值出现乱码 \xac\xed\x00\x05t\x00

最近使用spring-data-redis RedisTemplate 操作redis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

[html] view plain copy print ?

1. 127.0.0.1:6379> keys *  
2. 1) "\xac\xed\x00\x05t\x00\x04pass"  
3. 2) "\xac\xed\x00\x05t\x00\x04name"  
4. 3) "name"  

127.0.0.1:6379> keys *1) "\xac\xed\x00\x05t\x00\x04pass"2) "\xac\xed\x00\x05t\x00\x04name"3) "name"

spring-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;

解决方法

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;
}
