Question

如果我使用String而不是JsonObject，则在缓存值中使用JsonObject（GSON Library）时会发生此错误，然后操作成功执行。

在缓存中插入数据时遇到的错误：

缓存配置：

CacheConfiguration<String, JsonObject> cacheConfig = new CacheConfiguration<>();
            cacheConfig.setName("CACHE_NAME");
            cacheConfig.setReadThrough(true);
            cacheConfig.setBackups(2);
            cacheConfig.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
            cacheConfig.setWriteThrough(true);
            cacheConfig.setCacheStoreFactory(FactoryBuilder.factoryOf(ObjectLoader.class));
            IgniteCache<String, JsonObject> cache = ignite.getOrCreateCache(cacheConfig);

运营：

1.创建JsonObject（使用GSON库）

2.将缓存加载器设置为用于持久存储的给定缓存

3.从点燃客户端

将数据插入缓存

4.观察问题

问题是，self.env['hr.payslip'].salaryfunction()具有JsonObject类型的members字段，而Ignite LinkedTreeMap是默认字段，会将其反序列化为BinaryMarshaller某种原因。

~~为避免这种情况，您可以使用其他编组程序，例如LinkedHashMap。~~

<强> UPD：

原来，如果你配置OptimizedMarshaller，那么只有来自缓存的put和gets才能正常工作。但是，如果您尝试OptimizedMarshaller get(...)的反序列化表示的某个字段，那么JVM将崩溃。

原因是JsonObject具有以下LinkedTreeMap方法：

writeReplace()

因此，如果您序列化它，然后反序列化，那么您将获得private Object writeReplace() throws ObjectStreamException { return new LinkedHashMap(this); }而不是LinkedHashMap的实例。所以，LinkedTreeMap没有做错任何事。

<强>要点：

看起来你不应该将BinaryMarshaller放入缓存中。它没有实现JsonObject，因此作者没有考虑序列化它。我想，你必须用JSON字符串替换Serializable。

在Ignite缓存中插入数据时出现以下错误？
