Question

我在Hazelcast反序列化方面遇到了一些问题。我不知道为什么会发生这种情况。

当我使用Maven构建项目时，我可以看到下一个错误代码：

GRAVE: Failed to execute callback:     com.hazelcast.client.proxy.ClientMapProxy$1@382710c7! Request:     com.hazelcast.map.impl.client.MapGetRequest@cbe959e, response: HeapData{type=-    25,

ExceptionCauseEnum在我的类路径中。

我的 Hazelcast实例配置（以防它有用）：

<hz:hazelcast id="instance">
    <hz:config>
        <hz:group name="${name}"
            password="${pass}" />

        <hz:network port="23456"
            port-auto-increment="true">
            <hz:join>
                <hz:multicast
                    enabled="false"
                    multicast-group="${multicast-group}"
                    multicast-port="${multicast-port}" />
                <hz:tcp-ip enabled="true">
                    <hz:interface>127.0.0.1</hz:interface>
                </hz:tcp-ip>
            </hz:join>
            <hz:interfaces enabled="false">
                <hz:interface></hz:interface>
            </hz:interfaces>
        </hz:network>

        <hz:map name="myMap" max-size="5000" max-idle-seconds="3600" 
            time-to-live-seconds="7200" eviction-percentage="25"
            eviction-policy="LRU" />
    </hz:config>
</hz:hazelcast>

虽然Maven把这个错误抛给了我，但是它构建正确。

知道发生了什么，我做错了什么？

提前致谢。

我有一个类似的问题：在我的情况下，我的枚举有一个构造函数，所以我的解决方案是创建一个无参数的构造函数。

Hazelcast无法对枚举类进行反序列化
