SOLR:索引失败.回滚所有更改.

Question

我在dataconfig_1.xml中有以下内容

<?xml version="1.0" encoding="UTF-8"?>
<dataConfig>
  <dataSource batchSize="-1" convertType="true" driver="com.mysql.jdbc.Driver" password="solrpw" url="jdbc:mysql://127.0.0.1/solrDB" user="solruser"/>
  <document name="items">
    <entity name="root" pk="id" preImportDeleteQuery="data_source:1" query="select a.id, a.body, a.headline  title ,a.date  datecreated, a.title_id ,t.name  publisher_name from article as a inner join title as t on t.id=a.title_id" transformer="TemplateTransformer" deltaImportQuery="select a.id, a.body, a.headline  title ,a.date  datecreated, a.title_id ,t.name  publisher_name from article as a inner join title as t on t.id=a.title_id where last_update_time > '${dataimporter.last_index_time}'" deltaQuery="select id from article where last_update_time > '${dataimporter.last_index_time}'">
      <field column="data_source" template="1"/>
      <field column="data_source_type" template="Jdbc"/>
      <field column="data_source_name" template="syndigate_solr"/>
    </entity>
  </document>
</dataConfig>

在dataimport_1.properties我有

#Tue Aug 02 06:53:21 UTC 2011
last_index_time=2011-08-02 06\:52\:51
root.last_index_time=2011-08-02 06\:52\:51

现在每当我运行deltaimport

http://myip:8888/solr/collection1/dataimport_1?command=delta-import

我收到了以下回复

我对错误的看法？谢谢你的帮助

Answer 1

我调试jdbc导入错误的方法是使用log4jdbc库.我在data-config.xml中创建了一个新的数据源

<dataSource name="logMe" driver="net.sf.log4jdbc.DriverSpy" user="myUserName" password="myPassword" type="JdbcDataSource" url="jdbc:log4jdbc:mysql://myServer:3306/myDB" />

并设置所有实体以使用此新数据源.

然后我会运行导入.之后,我会查看名为sql.log的日志文件.在文件的底部,它通常会告诉我jdbc在哪里停止以及出现了什么错误.
