我正在Cloudera发行版（Cloudera搜索）中与Solr合作。我正在尝试实现货币字段类型并进行一些交换操作。我使用 solr.CurrencyField 类成功实现了它，但是不幸的是，查询它们时交换操作无法正常工作。
我发现上一个类已经过时了，应该改用 solr.CurrencyFieldType ，但是当我在架构中实现它时，会返回以下错误：

在这里，我保留了schema.xml文件的副本：
<fieldType name="currency" class="solr.CurrencyFieldType"
amountLongSuffiex="_l_ns" codeStrSuffix="_s_ns"
defaultCurrency="USD" currencyConfig="currency.xml"/>
谢谢大家！
