關(guān)鍵問(wèn)題是返回到頁(yè)面的是一個(gè)個(gè)對(duì)象。如果把搜索的結(jié)果中的關(guān)鍵字設(shè)置為高亮，謝謝
InfoPushController:
Page page = infoPushManager.searchKeyword(keyword,request.getParameter("pageNo"),best,category);
List list = new ArrayList();
if(page != null)
list = (List)page.getResult();
mav.addObject("infoPushs", list);
//關(guān)鍵問(wèn)題是返回到頁(yè)面的是一個(gè)個(gè)對(duì)象。

InfoPushManager 里的2個(gè)方法:
public Page searchKeyword(String keyword,String pageNoStr,int best,String category)
{
int pageNo = 1;
if (StringUtils.isNotEmpty(pageNoStr))
pageNo = Integer.parseInt(pageNoStr);
try{
IndexSearcher searcher = new IndexSearcher(IndexReader.open(Constants.INDEX_STORE_PATH));
String bestStr = String.valueOf(best);
/***** 一個(gè)關(guān)鍵字，在兩個(gè)字段中查詢 *****/
/*
* 1.BooleanClause.Occur[]的三種類型：
* MUST : + and
* MUST_NOT : - not
* SHOULD : or
* 2.下面查詢的意思是：content中必須包含該關(guān)鍵字，而title有沒(méi)有都無(wú)所謂
* 3.下面的這個(gè)查詢中，Occur[]的長(zhǎng)度必須和Fields[]的長(zhǎng)度一致。每個(gè)限制條件對(duì)應(yīng)一個(gè)字段
