Masalah pelik apabila membuat indeks menggunakan solrj?

Question

@RequestMapping(nilai = "/solr", kaedah = RequestMethod.GET)

public void getSolr() throws SolrServerException, IOException {

    String urlString = "http://192.168.10.129:8983/solr/mycore";
    SolrClient client = new HttpSolrClient.Builder(urlString).build();
    SolrInputDocument doc = new SolrInputDocument();
    doc.addField("id", "c");
    client.add(doc);
    client.commit();
}

Hanya buat indeks dan kemudian laporkan ralat

doc telah ditambahkan, tetapi komit gagal.

Jika anda membahagikan tambah dokumen dan komit kepada 2 permintaan, tidak akan ada masalah, seperti berikut:

@RequestMapping(value = "/solr", method = RequestMethod.GET)
    public void getSolr() throws SolrServerException, IOException {

        String urlString = "http://192.168.10.129:8983/solr/mycore";
        SolrClient client = new HttpSolrClient.Builder(urlString).build();
        SolrInputDocument doc = new SolrInputDocument();
        doc.addField("id", "c");
        client.add(doc);
    }
    @RequestMapping(value = "/solr2", method = RequestMethod.GET)
    public void getSolr2() throws SolrServerException, IOException {

        String urlString = "http://192.168.10.129:8983/solr/mycore";
        SolrClient client = new HttpSolrClient.Builder(urlString).build();
        client.commit();
    }

Tiada masalah dalam melaksanakan operasi pertanyaan.

Penyelesaian sementara, gunakan kaedah berikut untuk menghantar:

UpdateRequest req = new UpdateRequest();
        req.setAction(UpdateRequest.ACTION.COMMIT, false, false);
        req.add(doc);
        UpdateResponse rsp = req.process(client);

Kenapa ni okay? Masih sangat pelik
