我们正在构建一个Solr插件来链接我们的专有引擎。预期用途是完全替换标准标记器。 （这是背景：Hybrid search and indexing: words and token metadata in Solr）
尝试在Solr Admin中索引测试文档时：
id,title
12345,A test title
我想得到一个例外，我想，我的标记器正在开始。
配置更改（schema.xml）是：
<fieldType name="text_general" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="com.linguasys.carabao.ViaWebTokenizerFactory" url="http://blahblah/carabao/?wsdl"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<!--
<analyzer type="query">
<tokenizer class="com.linguasys.carabao.ViaWebTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
-->
</fieldType>
<fieldType name="family_id_space_delimited_list" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="com.linguasys.carabao.ViaWebTokenizerFactory" url="http://blahblah/carabao/?wsdl"/>
<!--
<filter class="com.linguasys.carabao.FamilyIDFilterFactory" />
-->
</analyzer>
</fieldType>
<fieldType name="role_space_delimited_list" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="com.linguasys.carabao.ViaWebTokenizerFactory" url="http://blahblah/carabao/?wsdl"/>
<!--
<filter class="com.linguasys.carabao.RoleFilterFactory" />
-->
</analyzer>
</fieldType>
Web服务本身有效。 （过滤器已被注释掉，因为它们因某种类型的不匹配错误而崩溃，但以后会出现这种情况。）
例外情况如下。它不只是＆＃34;我做错了什么＆＃34;，它＆＃34;我在哪里获得更多信息？＆＃34;

您需要验证调用yourTokenizer.create(java.io.Reader reader)时会发生什么。从堆栈跟踪看起来，此方法返回null，并且此值一直传播到AttributeSource.<init>(AttributeSource.java:94)。此时返回null是非法的，因此是例外。
找出正在发生的事情的最佳方法是启用调试器并停在上面提到的行。
