Question

我正在尝试使用SolrJ使用Solr为Word和PDF文档建立索引，但是我在互联网上找到的大多数示例都使用SolrServer类，我认为现在已经弃用了该类。与Solr本身的连接正在工作，因为我可以将SolrInputDocuments添加到索引，但是由于出现异常，它不适用于丰富的文档。

public static void main(String[] args) throws IOException, SolrServerException {
    String urlString = "http://localhost:8983/solr/localDocs16";
    HttpSolrClient solr = new HttpSolrClient.Builder(urlString).build();

    //is working
    /for(int i=0;i<1000;++i) {
        SolrInputDocument doc = new SolrInputDocument();
        doc.addField("cat", "book");
        doc.addField("id", "book-" + i);
        doc.addField("name", "The Legend of the Hobbit part " + i);
        solr.add(doc);
        if(i%100==0) solr.commit();  // periodically flush
    }

    //is not working
    File file = new File("path\\testfile.pdf");

    ContentStreamUpdateRequest req = new ContentStreamUpdateRequest("update/extract");

    req.addFile(file, "application/pdf");
    req.setParam("literal.id", "doc1");
    req.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
    try{
        solr.request(req);
    }
    catch(Exception e){
        System.out.println(e.getClass().getName() + "message: " + e.getMessage());
    } finally{
        solr.commit();
    }
}

我正在使用Maven并创建了一个JAR文件，然后尝试从命令行运行该文件，并且收到了搜索处理程序：application / pdf 的 Bad contentType错误的RemoteSolrException消息：

使用SolrJ为丰富的文档建立索引-搜索处理程序的contentType不好
