我配置了solrindex-mapping.xml（nutch）並配置了我的solr schema.xml和solrconfig.xml。單運行兩個運作良好，但如果我用bin/nutch solrindex ...我得到一個異常：apache nutch（版本1.2）集成在apach solr（trunk）中的問題 - 獲得solr異常
org.apache.solr.common.SolrException: Document [null] missing required field: id
我已經配置在所有的配置，文件id。在solrindex-mapping.xml它映射從url到id和在 solr我也配置了id。我不知道什麼是錯的。我將一些日誌輸出添加到org.apache.nutch.indexer.solr.SolrWriter.java。我在這些行添加一個loginfo，當讀取的字段被添加到SolrInputDocument。構建和運行後的結果是：
2010-09-11 21:31:06,326 INFO solr.SolrWriter - write()
2010-09-11 21:31:06,327 INFO solr.SolrWriter - Key: segment, value: 20100911212934

2010-09-11 21:31:06,327 INFO solr.SolrWriter - close()
您將只能看到3個讀取字段O_o。有誰知道我的配置是否有問題？ 我需要運行Nutch的真快，因爲我目前正在寫關於我的學士論文：/（在地方網絡的異構數據源的信息集成）
