Java 如何使用Solr 5正确创建blob索引字段？

我想我问题的标题解释了我需要的很多东西。我使用的是ApacheSolr5。我配置了solrconfig.xml、schema.xml和data-config.xml。它现在起作用了

但是，我需要再添加一个字段。Oracle Blob字段。首先，让我展示一下我的配置：

data-config.xml

如您所见，我有1369条记录，但SOLR只索引64个文档。如果我从模式中删除字段图片，或者将index和stored属性设置为false，则SOLR import all documents

我打开SOLR日志，在导入blob字段时发现此错误：

3436212 [Thread-19] WARN  org.apache.solr.handler.dataimport.SolrWriter  – Error creating document : SolrInputDocument(fields: [name=PRODUCTNAME, price=PRICE, store=STORE, picture=oracle.sql.BLOB@4130607a, _version_=1497915495941144576])

然后，我重新启动SOLR，重新加载我的内核，并再次执行完整导入。没有成功，同样的例外。我上面描述的64个文档已经导入，JSON响应中没有显示字段图片。我执行的查询是：

/select?q=*%3A*&wt=json&indent=true

我可以问一下，为什么要为BLOB编制索引，而不仅仅是存储它？你不会去搜索它，是吗-只是用搜索结果显示它？我想知道如果您为该字段设置index=false，您的索引是否会起作用。因为我尝试了所有方法使其起作用。我已经设置了index=false、stored=false和任何其他组合。力不行。同样的例外。您肯定不希望存储=false。可能值得尝试对图像进行base64编码。

<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="_version_" type="long" indexed="true" stored="true"/>
<field name="_text" type="string" indexed="true" stored="false" multiValued="true"/>
<field name="name" type="string" indexed="true" stored="true"/>
<field name="price" type="float" indexed="true" stored="true"/>

<!-- BLOB field -->
<field name="picture" type="binary" indexed="true" stored="true"/>

<copyField source="*" dest="_text"/>
<!-- ommited solr default fields -->
