redis key/value 出现\xAC\xED\x00\x05t\x00\x05

1.问题现象：

最近使用spring-data-redis 和jedis 操作redis时发现存储在redis中的key不是程序中设置的string值，前面还多出了许多类似\xac\xed\x00\x05t\x00这种字符串

2.原因：

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。

public void afterPropertiesSet() {

super.afterPropertiesSet();

boolean defaultUsed = false;

if (defaultSerializer == null) {

defaultSerializer = new JdkSerializationRedisSerializer(
classLoader != null ? classLoader : this.getClass().getClassLoader());
}

if (enableDefaultSerializer) {

if (keySerializer == null) {
keySerializer = defaultSerializer;
defaultUsed = true;
}
if (valueSerializer == null) {
valueSerializer = defaultSerializer;
defaultUsed = true;
}
if (hashKeySerializer == null) {
hashKeySerializer = defaultSerializer;
defaultUsed = true;
}
if (hashValueSerializer == null) {
hashValueSerializer = defaultSerializer;
defaultUsed = true;
}
}

if (enableDefaultSerializer && defaultUsed) {
Assert.notNull(defaultSerializer, "default serializer null and not all serializers initialized");
}

if (scriptExecutor == null) {
this.scriptExecutor = new DefaultScriptExecutor<K>(this);
}

initialized = true;
}

3.解决方案

public class RedisDao {

private static final Logger log = LoggerFactory.getLogger(RedisDao.class);

private RedisTemplate redisTemplate;

private RedisTemplate<String, Object> redisTemplateMap;

@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;
}

将redisTemplate默认改为stringRedis序列化方式。
