我正在进行搜索,我试图将响应从 a 转换HttpSolrServer
为 json 格式。响应以SolrDocumentList
. 我现在的代码是:
SolrQuery solrQuery = new SolrQuery(query);
solrQuery.setParam("wt", "json"); //doesn't affect the return format
QueryResponse rsp = solrServer.query(solrQuery);
SolrDocumentList docs = rsp.getResults();
return docs.toString();
当我打印出退货时,它会返回为:

搜索canon
使用他们的示例数据。
如果我这样做,return rsp.toString();
我会用它来取回标题信息:
{responseHeader={status=0,QTime=1,params={indent=true,q=canon\*,wt=xml,version=2.2}},response={numFound=2,start=0,docs=[SolrDocument{cat=[electronics, camera], features=[3x zoop, 7.1 megapixel Digital ELPH, movie clips up to 640x480 @30 fps, 2.0" TFT LCD, 118,000 pixels, built in flash, red-eye reduction], id=9885A004, inStock=true, includes=32MB SD card, USB cable, AV cable, battery, manu=Canon Inc., manufacturedate_dt=Mon Feb 13 10:26:37 EST 2006, name=Canon PowerShot SD500, popularity=7, price=329.95, store=45.17614,-93.87341, weight=6.4}, SolrDocument{cat=[electronics, multifunction printer, printer, scanner, copier], features=[Multifunction ink-jet color photo printer, Flatbed scanner, optical scan resolution of 1,200 x 2,400 dpi, 2.5" color LCD preview screen, Duplex Copying, Printing speed up to 29ppm black, 19ppm color, Hi-Speed USB, memory card: CompactFlash, Micro Drive, SmartMedia, Memory Stick, Memory Stick Pro, SD Card, and MultiMediaCard], id=0579B002, inStock=true, manu=Canon Inc., name=Canon PIXMA MP500 All-In-One Photo Printer, popularity=6, price=179.99, store=45.17614,-93.87341, weight=352.0}]}}
我知道HttpSolrServer
响应格式目前只能是 xml 或 javabin(我已设置为 xml)。这似乎对实际返回的结果及其格式没有影响。
我似乎找不到任何关于将响应转换为 json 的信息。有任何想法吗?
