分页控件

JSP
Java代码
<% Hashtable map = new Hashtable();
map.put("fileName", fileName);
map.put("startTime", startTime);
map.put("endTime", endTime);
map.put("fileStatus", fileStatus);%>
<%= PageHelper.NormalPager(request,
PageHelper.PER_PAGE_COUNT,
totalCount,
"summary.do",
UrlUtils.getParameterString(map))%>

后台代码
Java代码
public static String NormalPager(HttpServletRequest request, int pageSize,
int totalCount, String actionName, String paramString) {
return GeneratePager(request, pageSize, totalCount, actionName,
paramString);
}

Java代码
public static String GeneratePager(HttpServletRequest request,
int pageSize, int totalCount, String actionName, String paramString) {
int totalPages = GetTotalPageCount(totalCount, pageSize);

if (IsOnlyOnePage(totalPages)) {
return "";
}

int currentPage = GetCurrentPage(request, totalPages);

StringBuilder output = new StringBuilder();
output.append("

Java代码
private static int GetTotalPageCount(int totalCount, int pageSize) {
logger.debug("totalCount:" + totalCount);
logger.debug("pageSize:" + pageSize);
return Math.max((totalCount + pageSize - 1) / pageSize, 1);
}

Java代码
private static void HandleFirstPage(StringBuilder output, int currentPage,
String actionName, String paramString) {
if (CurrentInFirstPage(currentPage)) {
output.append("First");
} else {
output.append(String.format(
"First", actionName, 1,
paramString));
}
}

Java代码
private static void HandleNextPage(StringBuilder output, int totalPages,
int currentPage, String actionName, String paramString) {

if (CurrentInLastPage(currentPage, totalPages)) {
output.append("next");
} else {
output.append(String.format(
"next", actionName,
currentPage + 1, paramString));
}
}
