要将数据从我的数据库导入 Apache Solr，我正在使用 DataImportHandler。DataImportHandler 的集成是成功的，索引也是如此。但是“处理的文档总数”为 0，我在日志中找不到错误。
我将 Apache Solr 3.5 与 Drupal 一起使用，并且很多项目都已编入索引。所以，schema.xml 已经有很多字段了。使用 DataImportHandler，我想添加更多内容，因此需要添加更多字段。为了进行测试，我有一个测试数据库，其中有一列“id”（主键）和另一列“test_name”（文本）。
在其他帖子中，我经常看到类似的问题，但没有什么可以帮助我，所以我希望，你可以。我不知道我的字段匹配是否有问题，或者是否是另一个问题。
这是我的 dataconfig.xml：
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" encoding="UTF-8"
url="jdbc:mysql://localhost/test_db"
user="user" password="password" batchSize="-1"/>

<field column="ID" name="id" />
<field column="TEST_NAME" name="test_name" />
</entity>
</document>
</dataConfig>
