索引失败.回滚所有更改. (Solr数据导入)

问题描述

当我尝试运行domain.com:8080/solr/dataimport?command=full-import时，出现错误Indexing failed. Rolled back all changes.

When I try to run domain.com:8080/solr/dataimport?command=full-import, I get the error Indexing failed. Rolled back all changes.

没有其他错误消息通知我什么时候出错?有什么建议吗?

There's no additional error message to inform me what when wrong? Any suggestions?

data-config.xml

 <dataConfig>

    <dataSource
        name="mysql"
        driver="com.mysql.jdbc.Driver"
        url="jdbc:mysql://localhost/databasename"
        user="myusername"
        password="mypassword" />

    <document>

        <entity
            name="posts"
            datasource="mysql"
            query="select id, title, description from posts"
            deltaQuery="select id, title, description from posts where updated_at > '${dataimporter.last_index_time}'">\
        </entity>
        <field column="id" name="id" indexed="true" stored="true" />
        <field column="title" name="title" indexed="true" stored="true" />
        <field column="description" name="description" indexed="true" stored="true" />

    </document>

</dataConfig>
