Jedis和redisTemplate 共用问题--序列化不一致(生产事故-＞解决-＞两个redisTemplate)

Jedis和redisTemplate 共用问题
老项目用Jedis,放入redis中,用的是比较老的框架,还进行序列化.
用redisTemplate试了下拿不到.因为序列化的方式不同

Jedis
老项目的Put方法.

@Override
public boolean put(String key, Object value, int TTL) throws Exception {
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
jedis.set(SerializeUtil.serialize(key), SerializeUtil.serialize(value));
jedis.expire(SerializeUtil.serialize(key), TTL);
} catch (Exception e) {
log.error("缓存存入失败", e);
return false;
} finally {
returnResource(jedisPool, jedis);
}

return true;
}

然后把工具类搬过来了

public class SerializeUtil {
/**
*序列化
*
* @param object
* @return
*/
public static byte[] serialize(Object object) {
ObjectOutputStream oos = null;
ByteArrayOutputStream baos = null;
try {
baos = new ByteArrayOutputStream();
oos = new ObjectOutputStream(baos);
oos.writeObject(object);
byte[] bytes = baos.toByteArray();
return bytes;
} catch (Exception e) {

}
return null;
}

/**
* 反序列化
*
* @param bytes
* @return
*/
public static Object unserialize(byte[] bytes) {
ByteArrayInputStream bais = null;
try {
bais = new ByteArrayInputStream(bytes);
ObjectInputStream ois = new ObjectInputStream(bais);
return ois.readObject();
} catch (Exception e) {

}
return null;
}
}

写个测试来看看

@Test
public void test1() {

Jedis jedis = null;
jedis = new Jedis("localhost", 6379);

jedis.set(SerializeUtil.serialize("xx"), SerializeUtil.serialize("brgfewfe"));
jedis.expire(SerializeUtil.serialize("xx"), 3000);
}

redisTemplate尝试和解决
配置什么就不说了,想着这样应该能解决吧,发现不行.后来查了好多资料,发现redisTemplate的序列化需要配置方法

@Autowired
private static RedisTemplate redisTemplate;

ValueOperations valueOperations = redisTemplate.opsForValue();
Object wenzhouToken = valueOperations.get(SerializeUtil.serialize("xx"));
System.out.println(wenzhouToken);

于是

RedisSerializerUtil redisSerializerUtil = new RedisSerializerUtil();
redisTemplate.setKeySerializer(redisSerializerUtil);
redisTemplate.setHashKeySerializer(redisSerializerUtil);
redisTemplate.setValueSerializer(redisSerializerUtil);
redisTemplate.setHashValueSerializer(redisSerializerUtil);
ValueOperations valueOperations = redisTemplate.opsForValue();
valueOperations.set("xx",token,3000, TimeUnit.SECONDS);

附上序列化工具类

public class RedisSerializerUtil implements RedisSerializer<Object> {
private final Charset charset;

public RedisSerializerUtil() {
this(Charset.forName("UTF8"));
}

public RedisSerializerUtil(Charset charset) {
Assert.notNull(charset, "Charset must not be null!");
this.charset = charset;
}

@Override
public byte[] serialize(Object object) throws SerializationException {

return object == null ? null : SerializeUtil.serialize(object);
}

@Override
public Object deserialize(byte[] bytes) throws SerializationException {
return bytes == null ? null : SerializeUtil.unserialize(bytes);
}
}

这样就和上面的jedis序列化一样了,就可以取了
一点,用完后记得还原默认的序列化方式

RedisSerializerUtil redisSerializerUtil = new RedisSerializerUtil();
redisTemplate.setKeySerializer(redisSerializerUtil);
redisTemplate.setHashKeySerializer(redisSerializerUtil);
redisTemplate.setValueSerializer(redisSerializerUtil);
redisTemplate.setHashValueSerializer(redisSerializerUtil);
ValueOperations valueOperations = redisTemplate.opsForValue();
valueOperations.set("xx",token,3000, TimeUnit.SECONDS);
StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
redisTemplate.setKeySerializer(stringRedisSerializer);
redisTemplate.setHashKeySerializer(stringRedisSerializer);
redisTemplate.setValueSerializer(stringRedisSerializer);
redisTemplate.setHashValueSerializer(stringRedisSerializer);

问题！！！
线上发布后，发现和RedisConfig

@Bean
@SuppressWarnings("all")
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, Object> template = new RedisTemplate<String,
Object>();
template.setConnectionFactory(redisConnectionFactory);
// Json序列化配置
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new
Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
// String 的序列化
StringRedisSerializer stringRedisSerializer = new
StringRedisSerializer();
// key采用String的序列化方式
template.setKeySerializer(stringRedisSerializer);
// hash的key也采用String的序列化方式
template.setHashKeySerializer(stringRedisSerializer);
// value序列化方式采用jackson
template.setValueSerializer(jackson2JsonRedisSerializer);
// hash的value序列化方式采用jackson
template.setHashValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}

两边序列化不一样，然后线上用的定时刷新字典炸了！！！抢救了1个多小时。我的天

注意序列化一定要一致

第二版代码类似，只是把序列化一致了，线上没出现问题。但是不能心存侥幸，因为有可能在设置序列化后还没来得及换回原来的方式，这个时间节点，可能会执行刷新字典的方法，这个时候还是会出现问题！！！

后来经过高人指点，配置两个redisTemplate也就隔离开，最终代码

@Configuration
@EnableCaching //开启注解
public class RedisConfig extends CachingConfigurerSupport {
//编写redisTemplate
@Bean
@SuppressWarnings("all")
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, Object> template = new RedisTemplate<String,
Object>();
template.setConnectionFactory(redisConnectionFactory);
// Json序列化配置
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new
Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
// String 的序列化
StringRedisSerializer stringRedisSerializer = new
StringRedisSerializer();
// key采用String的序列化方式
template.setKeySerializer(stringRedisSerializer);
// hash的key也采用String的序列化方式
template.setHashKeySerializer(stringRedisSerializer);
// value序列化方式采用jackson
template.setValueSerializer(jackson2JsonRedisSerializer);
// hash的value序列化方式采用jackson
template.setHashValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}

 

@Bean(name = "SerializeRedisTemplate")
public RedisTemplate<String, Object> getRedisTemplate1(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, Object> template = new RedisTemplate<String,
Object>();
template.setConnectionFactory(redisConnectionFactory);
// Json序列化配置

ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

RedisSerializerUtil redisSerializerUtil = new RedisSerializerUtil();
template.setKeySerializer(redisSerializerUtil);
template.setHashKeySerializer(redisSerializerUtil);
template.setValueSerializer(redisSerializerUtil);
template.setHashValueSerializer(redisSerializerUtil);
return template;
}
}

这样就隔离开来了

1 @Resource(name = "SerializeRedisTemplate")
2 private RedisTemplate serializeRedisTemplate;
3 
4 
5 redisTemplate.opsForValue().set("xx", token, 60 * 40, TimeUnit.SECONDS);
6 serializeRedisTemplate.opsForValue().set("xx", token, 60 * 40, TimeUnit.SECONDS);
