点击查找只是刷新页面，后台没有问题，但是又实现不了
具体代码：
<% request.setCharacterEncoding("utf-8"); %>
<%!
private static final String DBDRIVER ="org.gjt.mm.mysql.Driver";
private static final String DBURL ="jdbc:mysql://localhost:3306/tushu";
private static final String DBUSER = "root";
private static final String DBPASSWORD ="admin";
%>
<%
Connection conn =null;
PreparedStatement pstmt =null;
ResultSet rs =null;
%>
<%
int pageCount = 5;//每页显示行数
int rowCount = 0;//总记录数
int currentPage = 1;//当前页码
int sumPageCount = 0;//总的页数
int currentRow = 1;
%>
<%
String word=null;
String strPage = request.getParameter("page");
if(word!=null){
word=new String(request.getParameter("key").getBytes("ISO-8859-1"),"utf-8");
word = request.getParameter("key");
}
if(strPage==null){
currentPage = 1;
}else{
currentPage = Integer.parseInt(strPage);
}
%>
<%
try{
Class.forName(DBDRIVER);
conn = DriverManager.getConnection(DBURL, DBUSER, DBPASSWORD);
String sql = null;
if(word==null){
sql = "select b_ID,b_Name,b_Author,b_Translator,chub,b_Price,b_Quantity from bookinfo";

pstmt.setString(1,"%"+word+"%");
pstmt.setString(2,"%"+word+"%");
}
rs = pstmt.executeQuery();
rs.last();
rowCount = rs.getRow();
if(rowCount % pageCount == 0){

<%
