totalRecords 总记录数
list 保存分页的数据
pageNo 当前页
pageSize 页大小
query 保存用户查询的字符串
pageAction 操作分页的Servlet或Action(struts)
method (struts中Action对应的method)


/
private int totalRecords;
private List list;
private int pageNo;
private int pageSize;
private String query;
private String pageAction;
private String method;
public void setPageAction(String pageAction) {
this.pageAction = pageAction;
}
public void setMethod(String method) {
this.method = method;
}
public List getList() {
return list;
}

this.list = list;
}

return pageNo;
}

this.pageNo = pageNo;
}

return pageSize;
}

return totalRecords;
}
public void setTotalRecords(int totalRecords) {

}
/
取得总页数的方法 return
totalRecords%pageSize==0?(totalRecords/pageSize):(totalRecords/pageSize+1)

@return
/
public int getTotalPages() {
return (totalRecords + pageSize - 1) / pageSize;
}
/
得到首页

@return
/
public int getTopPage() {
return 1;
}
/
得到上一页

@return
/
public int getPreviousPageNo() {
if (pageNo <= 1)
return 1;
else
return (pageNo - 1);
}
/
得到下一页

@return
/
public int getNextPageNo() {
if (pageNo >= getTotalPages()) {
return getTotalPages() == 0 ? 1 : getTotalPages();
} else {
return pageNo + 1;
}
}
/
得到尾页

@return
/
public int getBottomPageNo() {
return getTotalRecords() == 0 ? 1 : getTotalPages();
}
