How can开发者_如何学Go I load data from an xml file into solr using the solrj API?
Thanks Pascal. I miss worded my question, I'm actually using groovy. But in any event your approach does work, but this was my solution:
CommonsHttpSolrServer server = SolrServerSingleton.getInstance().getServer();
def dataDir = System.getProperty("user.dir");
File xmlFile = new File(dataDir+"/book.xml");
def xml = xmlFile.getText();
DirectXmlRequest xmlreq = new DirectXmlRequest( "/update", xml);
server.request(xmlreq);
server.commit();
The first arg to DirectXmlRequest is a url path, it must be "/update" and that the variable xml is a string containing the XML. For example
<add>
<doc>
<field name="title">blah</field>
</doc>
</add>
With Java 6, you can use Xpath to fetch what you need from your xml file. Then, you populate a SolrInputDocument from what you extracted from the xml. When that document contains everything you need, you submit it to Solr using the add method of SolrServer.
SolrClient client = new HttpSolrClient("http://localhost:8983/solr/jiva/");
String dataDir = System.getProperty("user.dir");
File xmlFile = new File(dataDir + "/Alovera-Juice.xml");
if (xmlFile.exists()) {
InputStream is = new FileInputStream(xmlFile);
String str = IOUtils.toString(is);
DirectXmlRequest dxr = new DirectXmlRequest("/update", str);
client.request(dxr);
client.commit();
}
