PageUtils分页工具类 solr查询 分页 高亮

pageUtils类

public class PageUtils {
//当前页
 private int currentPage;
 //上一页
 private int prevPage;
 //下一页
 private int nextPage;
 //尾页
 private int lastPage;
 //数据总条数
 private int count;
 //每页条数
 private int  pageSize;
 //分页计入数
 private int pageRecord;
 //分页
 private String page;

public PageUtils(String currentPage,int count,int pageSize) {
  init(currentPage, count, pageSize);
  initPrevPage();
  initLastPage();
  initNextPage();
  initPageRecord();
  initPage();
 }


//初始化变量的值
 private void init(String currentPage,int count,int pageSize) {
  if(currentPage==null||currentPage.equals("")) {
   currentPage="1";
  }
  this.currentPage = Integer.parseInt(currentPage);
  this.count = count;
  this.pageSize = pageSize;
 }

//计算上一页
 private void initPrevPage() {
  if(currentPage==1) {
   prevPage = 1;
  }else {
   prevPage = currentPage-1;
  }
 }

//计算最后一页
 private void initLastPage() {
  if(count%pageSize==0) {
   lastPage=count/pageSize;
  }else {
   lastPage=count/pageSize+1;
  }
 }

//计算下一页
 private void initNextPage() {
  if(currentPage==lastPage) {
   nextPage=lastPage;
  }else {
   nextPage=currentPage+1;
  }
 }


//计算计入数
 private void initPageRecord() {
  pageRecord = (currentPage-1)*pageSize;
 }

private void initPage() {
  page = "第"+currentPage+"/"+lastPage+"页，共"+count+"条数据。";
  page +="";
  page +="";
  page +="";
  page +="";
 }


 public int getCurrentPage() {
  return currentPage;
 }


public int getPrevPage() {
  return prevPage;
 }

public int getNextPage() {
  return nextPage;

public int getLastPage() {
  return lastPage;

public int getCount() {
  return count;
 }

public int getPageSize() {

public int getPageRecord() {

public String getPage() {

controller层 list分支 solr分页 高亮等

@RequestMapping("list.do")
public String list(@RequestParam(defaultValue="0")int typeid,String currentPage,Model model,@RequestParam(defaultValue="")String name) throws SolrServerException, IOException {

Map map = new HashMap();
  //solr查询条件对象
  SolrQuery query = new SolrQuery();
  //query.set("q", "*:*");
  if(name.equals("")) {
   name="*";
  }
  //设置查询条件
  query.setQuery(name);
  //默认域
  query.set("df","name");
  //高亮
  query.setHighlight(true);
  query.addHighlightField("name");
  query.setHighlightSimplePre("");
  query.setHighlightSimplePost("");
  //下拉列表的查询
  if(typeid ==0 || typeid ==1) {
   
  }else {
   query.setFilterQueries("typeid:"+typeid);
  }
  //分页
  int pageSize=2;
  //总页数
  int count = (int) sc.query(query).getResults().getNumFound();
  //分页对象
  PageUtils pageUtils = new PageUtils(currentPage, count, pageSize);
  //设置分页
  query.setStart(pageUtils.getPageRecord());
  query.setRows(pageUtils.getPageSize());

//执行查询
  QueryResponse response = sc.query(query);
  //封装到java集合
  List list = response.getBeans(Contract.class);
  //取出高亮的值进行替换
  Map>> highlighting = response.getHighlighting();
  for (Contract contract : list) {
  if(highlighting.get(contract.getId()).size()==0) {
    continue;
   }
   Map> map2 = highlighting.get(contract.getId());
   List list2 = map2.get("name");
   String name2 = contract.getName();
   if(list2!=null && list2.size()>0) {
    name2=list2.get(0);
   }
   contract.setName(name2);
   }
   
   if(name.equals("*")) {
   name="";
  }
  
  map.put("name", name);
  map.put("typeid", typeid);
  model.addAttribute("map", map);
  model.addAttribute("list", list);
  model.addAttribute("page", pageUtils.getPage());
  return "list";
  }
