Apache ignite:A 放置对象数据时出现关键错误

Question

我正在尝试 Apache ignite，但无法放入对象数据。服务器是 Java 中的单个节点。客户端是 .NET(C#) 中的瘦客户端。

这个版本是

服务器 OS:Ubuntu 18.04

JAVA:openjdk 版本 11.0.11

点燃：2.10.0

客户OS:Windows10

.NET:.NET Framework 4.6.2

ignite:2.10.0 (Nuget)

当客户端放置对象时，引发以下异常。

Apache.Ignite.Core.Client.IgniteClientException
  HResult=0x80131500
  Message=class org.apache.ignite.internal.processors.cache.CachePartialUpdateCheckedException: Failed to update keys (retry update if possible).: [100]

服务器出现同样的异常。

ignite的配置文件如下：

                <property name="classNames">

                            <value>ignitetest.Patient</value>
                        </list>
                </property>
                <property name="nameMapper">
                    <bean class="org.apache.ignite.binary.BinaryBasicNameMapper">

                    </bean>

        </property>
    </bean>
    <!-- <bean id="postgresDataSouorceTestdb" class="org.postgresql.ds.PGPoolingDataSource">...</bean> -->
</beans>

客户端来源如下：

var cfg = new IgniteClientConfiguration {
    Endpoints = new[] { "10.1.1.1:10800" },
    BinaryConfiguration=new BinaryConfiguration() {
        CompactFooter=true,
        NameMapper= new BinaryBasicNameMapper { IsSimpleName = true }
    }
};

using (var client = Ignition.StartClient(cfg)) {
    client.GetBinary().GetBinaryType(typeof(Patient));
    var cache = client.GetOrCreateCache<string, Patient>("PatientCache");
    var pat = new Patient() { PatientId = "100", Name = "Test", Birthday = new DateTime(1980,5,1) };
    pat.Birthday = pat.Birthday.ToUniversalTime();
    cache.Put("100", pat);
}

using (var client = Ignition.StartClient(cfg)) {
    var cache = client.GetOrCreateCache<string, Patient>("PatientCache");
    var pat = cache.Get("100");
    System.Diagnostics.Debug.WriteLine("Patient:{0},{1},{2}",pat.PatientId,pat.Name,pat.Birthday);
}

当注册数据为字符串时，注册成功。我无法弄清楚是什么原因造成的。

服务器上的缓存更新失败，因为 Patient class 不可序列化：

NotSerializableException: ignitetest.Patient

使 ignitetest.Patient 可序列化以解决问题。

查看日志中的内部异常 - CacheJdbcBlobStore 写入对象失败：
