我尝试使用CURL索引一些CSV文件。 首先我在shell中试过这个:
curl http://localhost:8080/solr/update/csv -F "stream.file=/home/usersolr/Data/production/MyFile_1373882442023" -F "commit=true" -F "header=false" -F "fieldnames=`cat /home/usersolr/Data/header/My_header`"
它的确有效,因为我收到了回复:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int name="QTime">1782</int></lst>
</response>
然后,我想在我的Java应用程序中集成这个命令行,我写了这段代码:
Runtime runtime = Runtime.getRuntime();
String cmd = "curl http://localhost:8080/solr/update/csv -F \"stream.file=/home/usersolr/Data/production/MyFile_1373882442023\" -F \"commit=true\" -F \"header=false\" -F \"fieldnames=`cat /home/usersolr/Data/header/My_header`\"";
System.out.println(cmd);
runtime.exec(cmd);
我得到了SolrException
:
org.apache.solr.common.SolrException: missing content stream.
我的文档没有编入索引。我在控制台中显示的cmd字符串与上面的shell命令完全相同。
我不管理getInputStream()
和getOutputStream()
方法。它与我的问题有关吗?

对于runtime.exec,你需要有一个命令数组,如下所示:
String cmd[] = new String[]{"curl", "http://localhost:8080/solr/update/csv", "-F", "\"stream.file=/home/usersolr/Data/production/MyFile_1373882442023\"", "-F" "\"commit=true\"", "-F", "\""header=false\"", "-F", "\"fieldnames=`cat /home/usersolr/Data/header/My_header`\""};

看起来您的URL输入未被提交,因此收到“缺少内容流”错误。
尝试以下命令,它应该可以工作。
curl http://localhost:8983/solr/update/csv?stream.file=exampledocs/books.csv&stream.contentType=text/plain;charset=utf-8
