Question

我需要索引PDF文件，我被告知Solr可以做到这一点。所以我在Weblogic上安装了一个Solr-Server，并尝试使用Web界面。

最后，我编写了一个JUnit-Test类，试图用Java和Solrj做同样的事情。

我编写了一个（简单）代码，用于索引几个pdf并执行查询以查看文档是否已编入索引：

@Test
  public void documentSearchTest() throws IDSystemException
  {
    try
    {
      server.deleteByQuery("*:*");

      Assert.assertTrue("Document not found! - " + TEST_PDF_DOCUMENT1, new File(TEST_PDF_DOCUMENT1).exists());
      Assert.assertTrue("Document not found! - " + TEST_PDF_DOCUMENT2, new File(TEST_PDF_DOCUMENT2).exists());

      req.addFile(new File(TEST_PDF_DOCUMENT1), CONTENT_TYPE_APPLICATION_PDF);
      req.addFile(new File(TEST_PDF_DOCUMENT2), CONTENT_TYPE_APPLICATION_PDF);

      NamedList<Object> result = server.request(req);

      SolrQuery solrQuery = new SolrQuery().setQuery("*:*");

      QueryResponse rsp = server.query(solrQuery);

      SolrDocumentList docs = rsp.getResults();

    }
    catch (SolrServerException sse)
    {
      throw new IDSystemException(LOG, sse.getMessage(), sse);
    }
    catch (IOException ioe)
    {
      throw new IDSystemException(LOG, ioe.getMessage(), ioe);
    }
  }

通过运行此测试，我收到以下错误：

我检查了weblogic设置（servers-＆gt; protocols-＆gt; http），并且Max Post Size设置为-1（应该是无限大小）。

是否还有其他必须设置的东西？

编辑：这里是solrconfig.xml

在ExtractingRequestHandler

的Solr配置中，Multipart文件的大小有限

您应该默认修改似乎为2048KB的值看着 <requestParsers enableRemoteStreaming="false" multipartUploadLimitInKB="2048" /> 在<requestDispatcher...>部分

在您的示例中，您必须将其放在solrconfig.xml：

中

<requestDispatcher handleSelect="false" >
    <requestParsers enableRemoteStreaming="true"
                multipartUploadLimitInKB="2048000" <-- set your size Here
                formdataUploadLimitInKB="2048"
                addHttpRequestToContext="false"/>
</requestDispatcher>

＆＃34;大小超过配置的最大值＆＃34;索引时出错
