java - Solr 异常 : org. apache.solr.common.SolrException:缺少内容流

Question

我遇到了这个异常:

我尝试使用 CURL 索引一些 CSV 文件。 首先我在shell中尝试过:

 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`"

它之所以有效，是因为我收到了回复:

<?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，我想将此命令行集成到我的 Java 应用程序中，我编写了以下代码:

    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.

而且我的文档没有索引。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。这与我的问题有关吗？

谢谢

对于runtime.exec，您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`\""};
