索引时"size exceeds the configured maximum"错误

Question

我需要索引PDF文件，有人告诉我Solr可以做到这一点。所以我在Weblogic上安装了一个Solr服务器，并尝试了一些关于Web界面的东西。

最后，我写了一个JUnit测试类，试图用Java和Solrj做同样的事情。

我写了一个(简单的)代码来索引几个pdf，并执行一个查询来查看文档是否被索引：

@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，我得到以下错误：

我检查了weblogic设置(服务器->协议->http)，然后最大发布大小设置为-1(应该意味着大小不受限制)。

是否还有其他必须设置的内容？

编辑：这里是solrconfig.xml

Answer 1

在ExtractingRequestHandler 的Solr配置中，多部分文件的大小受到限制

您应该修改默认值为2048KB的值看看<requestParsers enableRemoteStreaming="false" multipartUploadLimitInKB="2048" />在<requestDispatcher...>部分中

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>
