java - 意外的异常 - apache ignite - Web session 集群

Question

我正在尝试在 Tomcat 7 中设置“Web session 集群”。我跟着 http://apacheignite.gridgain.org/v1.5/docs/web-session-clustering具有复制的缓存模式。我遇到了一个异常(exception):

这是我的 web.xml:

</web-app>

和我的default-config.xml:

                                You can also optionally specify an individual port.
                            -->

                    </property>
                </bean>
            </property>
        </bean>
    </property>
</bean>

当然还有我的 pom.xml:

Answer 1

Ignite 配置不正确。 CacheConfiguration bean 必须作为 IgniteConfiguration 的一部分提供，并且还必须指定名称:

<bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
    <bean class="org.apache.ignite.configuration.CacheConfiguration">
        <!-- Cache name. -->
        <property name="name" value="replicated"/>

        <!-- Cache mode. -->
        <property name="cacheMode" value="REPLICATED"/>
    </bean>

    <!-- Discovery, etc... -->
</bean
