大虾们帮忙看看代码什么意思啊，看不懂！
String url = "zichanbaoxiu_list.jsp?1=1";
String sql = "select * from zichanbaoxiu where 1=1";
if(request.getParameter("zhuti")=="" ||request.getParameter("zhuti")==null ){}else{sql=sql+" and zhuti like '%"+request.getParameter("zhuti")+"%'";}
if(request.getParameter("baoxiuneirong")=="" ||request.getParameter("baoxiuneirong")==null ){}else{sql=sql+" and baoxiuneirong like '%"+request.getParameter("baoxiuneirong")+"%'";}
if(request.getParameter("baoxiuren")=="" ||request.getParameter("baoxiuren")==null ){}else{sql=sql+" and baoxiuren like '%"+request.getParameter("baoxiuren")+"%'";}
ArrayList list = PageManager.getPages(url,15,sql, request);
int i=0;
for(HashMap map:list){
i++;
多多少少有点抽象，谁写的，拖出去祭天😅。
你想问啥，代码好乱啊
