The value serializer of RedisTemplate automatically assembled by Spring Boot, the default is JdkSerializationRedisSerializer.
Because the com.itplh.model.dashboard.QueryDashboardResponseDTO here does not implement the java.io.Serializable interface.
So when calling DashboardCachingRedisImpl.putIfAbsent, an exception SerializationException occurred when serializing value
The source code is as follows.
org.springframework.boot.autoconfigure.cache.RedisCacheConfiguration
private org.springframework.data.redis.cache.RedisCacheConfiguration createConfiguration(
CacheProperties cacheProperties, ClassLoader classLoader) {<!-- -->
Redis redisProperties = cacheProperties.getRedis();
org.springframework.data.redis.cache.RedisCacheConfiguration config = org.springframework.data.redis.cache.RedisCacheConfiguration
.defaultCacheConfig();
config = config.serializeValuesWith(
SerializationPair.fromSerializer(new JdkSerializationRedisSerializer(classLoader)));
// ...
return config;
}
org.springframework.data.redis.serializer.JdkSerializationRedisSerializer
public JdkSerializationRedisSerializer(@Nullable ClassLoader classLoader) {<!-- -->
this(new SerializingConverter(), new DeserializingConverter(classLoader));
}
org.springframework.core.serializer.support.SerializingConverter
public SerializingConverter() {<!-- -->
this.serializer = new DefaultSerializer();
}
org.springframework.core.serializer.DefaultSerializer
public class DefaultSerializer implements Serializer<Object> {<!-- -->
/**
* Writes the source object to an output stream using Java serialization.
* The source object must implement {@link Serializable}.
* @see ObjectOutputStream#writeObject(Object)
*/
@Override
public void serialize(Object object, OutputStream outputStream) throws IOException {<!-- -->
if (!(object instanceof Serializable)) {<!-- -->
throw new IllegalArgumentException(getClass().getSimpleName() + " requires a Serializable payload " +
"but received an object of type [" + object.getClass().getName() + "]");
}
ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);
objectOutputStream.writeObject(object);
objectOutputStream.flush();
}
