sql-server - Solr DataImportHandler 与 SQL Server

Question

我在让 Solr 通过 Microsoft JDBC 驱动程序与 Microsoft SQL Server 对话时遇到问题。我在 solrconfig.xml 中注册了处理程序:

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
  <lst name="defaults">
    <str name="config">C:\Program Files\Apache Software Foundation\Tomcat 6.0\Solr\conf\data-config.xml</str>
  </lst>
</requestHandler>

在 data-config.xml 中，我定义了一个数据源和一个文档:

<?xml version="1.0" encoding="UTF-8" ?>
<dataConfig>
  <dataSource type="JdbcDataSource" name="ds1"
    driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
    url="jdbc:sqlserver://localhost;databaseName=myDB;responseBuffering=adaptive;"
    user="xxxx"
    password="xxxx"
    readOnly="true"
  />

  <document name="members">
    <entity name="member" datasource="ds1" pk="id"
      query = "select 
        MemberID as id,
        UserName as userName,
        FirstName as firstName,
        LastName as lastName,
        Birthday as birthday,
        PrimaryEmail as primaryEmail,
        PersonalStatement as personalStatement
        from member"
      transformer="DateFormatTransformer">
      <field column="Birthday" name="birthday" dateTimeFormat="yyyy-MM-dd" />
    </entity>      
  </document>
</dataConfig>

这些列相当无关紧要 - 我只想从一些项目开始，包括日期列。 Solr schema.xml 定义了一些字段:

<field name="id" type="tlong" indexed="true" stored="true" required="true" /> 
<field name="userName" type="text" indexed="true" stored="true" />
<field name="firstName" type="text" indexed="true" stored="true" />
<field name="lastName" type="text" indexed="true" stored="true" />
<field name="birthday" type="tdate" indexed="true" stored="true" />
<field name="primaryEmail" type="text" indexed="true" stored="true" />
<field name="personalStatement" type="text" indexed="true" stored="true" />

当我尝试导入时，日志显示构建数据源的异常:

我已经阅读了常见问题解答和文档，查看了尽可能多的资源，但我就是无法克服这个错误。我究竟做错了什么？每当配置出现任何问题时，都会显示错误“无法读取:dataimport.properties”。我找不到我的错误。

实体声明中似乎无法识别数据源，因为要使用的正确属性是 dataSource，而不是 datasource
