我试图将Cassandra放入Ignite中进行一些原型设计，并且遇到Ignite启动时遇到的一些困难。Ignite未启动示例配置，“找不到类CassandraHelper for bean”
到目前为止，我对Ignite所做的所有工作都是改变default-config.xml，添加一个connection-settings.xml并将Cassandra/Ignite的依赖关系添加到libs文件夹中。
此时，我无法启动Ignite。所有错误都与connection-settings.xml中引用的类有关。
我调试： 我开始与错误
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.apache.ignite.tests.utils.CassandraHelper] for bean with name 'contactPoints' defined...
我下载点燃的源代码来检查哪里哪里的连接settings.xml中的路径表示，他们的文件，它们包含的预期功能）。
找到。 -name CassandraHelper.java告诉我有两个这样的文件，用点燃的来源，名称：
./modules/cassandra/store/src/main/java/org/apache/ignite/cache/store/cassandra/common/CassandraHelper.java
./modules/cassandra/store/src/test/java/org/apache/ignite/tests/utils/CassandraHelper.java
这两个只有后者实际上包含函数getContactPointsArray。出于好奇，我改变了connection-settings.xml指向org.apache.ignite.cache.store.cassandra.common.CassandraHelper，果然，错误从“无法找到类”改为“没有这样的方法”getContactPointsArray “”。
看着源代码，我发现Ignite未能找到的其他文件也位于src/test目录下的预期位置，而不是src/main，所以我怀疑 - 由于某种原因Ignite正在搜索在src/main下，它应该在src/test下进行搜索。这似乎不是我应该手动配置的东西，我不知道如何通过connection-settings.xml告诉Ignite来查看其他目录下的Ignite。
对Ignite和Cassandra来说，我什么都不是专家，所以如果我在设置事物时犯了一些奇怪的错误，我不会感到惊讶，但是到目前为止我无法弄清楚我可能会犯什么错误取得了。任何建议，将不胜感激。
我的文件：
默认-config.xml中（从https://apacheignite.readme.io/v1.6/docs/examples拍摄，我删除cache2）。

预先感谢您！
通过米卡的建议和一些试验和错误，我已经改变cassandraRegularDataSource使用'<属性名=“contactPoints”值=“本地主机” />'而不是定义一个bean。这解决了这个问题，但我仍在调试其他方面。 – Oxirane
