私のアプリは、スプリング ブート + hazelcast に基づいています。
単純なエンティティをヘーゼルキャストに保存しようとしています:
public class ExampleMeeting implements Serializable {
private static final long serialVersionUID = 1L;
private String id;
private String name;
public ExampleMeeting(String id, String name) {
this.id = id;
this.name = name;
}
public ExampleMeeting() {
}
// getters and setters
}
私のサービスメソッドは次のようになります:
@CachePut(value = MEETING_CACHE_NAME, key = "#meeting.id")
public ExampleMeeting saveMeeting(ExampleMeeting meeting) {
LOGGER.info("Save meeting to cache {}", meeting);
return meeting;
}
com.hazelcast.nio.serialization.HazelcastSerializationExceptionトレースで受け取ったエンティティを保存しようとすると:
com.hazelcast.nio.serialization.HazelcastSerializationException: There is no suitable de-serializer for type 2. This exception is likely to be caused by differences in the serialization configuration between members or between clients and members.

ここに私のヘーゼルキャスト設定があります:
@Bean
HazelcastInstance hazelcastInstance() {
Config config = new ClasspathXmlConfig(hazelcatsConfig);
Map<String, MapConfig> mapConfigMap = new HashMap<String, MapConfig>();
ClassPathBeanDefinitionScanner scanner = new ClassPathBeanDefinitionScanner(applicationContext);
for (BeanDefinition bd : scanner.findCandidateComponents("com.egalacoral.spark")) {
String className = bd.getBeanClassName();
try {
Class<?> classObj = Class.forName(className);
Method[] methods = classObj.getDeclaredMethods();
for (Method method2 : methods) {
Cacheable annotation = AnnotationUtils.getAnnotation(method2, Cacheable.class);
if (annotation != null && annotation.value().length > 0) {
addMap(mapConfigMap, method2, annotation);
}
}
} catch (ClassNotFoundException e) {
LOGGER.error("Error while creating maps for caches", e);
}
}
config.setMapConfigs(mapConfigMap);
return Hazelcast.newHazelcastInstance(config);
}
この問題を解決する方法を教えてください。
更新:
protected void addMap(Map<String, MapConfig> mapConfigMap, Method method2, Cacheable annotation) {
MapConfig mapConfig = new MapConfig();
HazelcastMapConfig cacheConfig = AnnotationUtils.getAnnotation(method2, HazelcastMapConfig.class);
mapConfig.setEvictionPolicy(cacheConfig.evictionPolicy());
String timeToLiveSeconds = cacheConfig.timeToLiveSeconds();
if (StringUtils.hasText(timeToLiveSeconds)) {
timeToLiveSeconds = this.embeddedValueResolver.resolvePlaceholders(timeToLiveSeconds);
}
mapConfig.setTimeToLiveSeconds(Integer.parseInt(timeToLiveSeconds));
String key = annotation.value()[0];
mapConfigMap.put(key, mapConfig);
LOGGER.info("Created map for cache {} : {} ", key, mapConfig);
}
