麻烦哪位大神帮我弄的分页 下面我会贴出我的代码，我用的是Hibernate+spring+jsp
用maven写的 如果大神有工具类就帮我整合下吧 十分感谢 在线急等

我的邮箱jcnotnull0108@163.com  希望大神最好能在我发的代码基础上增加 不然直接给我工具类  我也不是太明白  谢谢 代码有点多所以我删掉了一些毕竟问题他描述要10000字以内

希望看到的都能帮帮忙 0.0提点意见都好

public Pager pagedQuery(String hql, int currentPage, int pageSize, Map<String, Object> parmeMap) {
    if (pageSize == 0) {
        pageSize = 10;
    }
    int totalRows = getTotalRows(hql, parmeMap);
    int totalPages = 0;
    if (totalRows % pageSize == 0) {
        totalPages = totalRows / pageSize;
    } else {
        totalPages = totalRows / pageSize + 1;
    }
    int start = (currentPage - 1) * pageSize;
    if (totalPages < 1) {
        return new Pager();
    }
    Query query = getSession().createQuery(hql).setCacheable(true);
    setParameter(query, parmeMap);
    List<Object> list = query.setFirstResult(start).setMaxResults(pageSize).list();
    return new Pager(totalRows, currentPage, totalPages, list);
}

public class Pager {

private int totalRows;

private int currentPage = 1;

private int pageSize;


private List<Object> data = new ArrayList<Object>();


public Pager() {
}


public Pager(int totalRows, int currentPage, int pageSize, List<Object> data) {
    this(currentPage, pageSize, data);
    this.totalRows = totalRows;
}


public Pager(int currentPage, int pageSize, List<Object> data) {
    super();
    this.currentPage = currentPage;
    this.pageSize = pageSize;
    this.data = data;
}


public int getCurrentPage() {
    return currentPage;
}


public void setCurrentPage(int currentPage) {
    this.currentPage = currentPage;
}


public List<Object> getData() {
    return data;
}


public void setData(List<Object> data) {
    this.data = data;
}


public int getTotalRows() {
    return totalRows;
}


public void setTotalRows(int totalRows) {
    this.totalRows = totalRows;
}


public int getPageSize() {
    return pageSize;
}

public void setPageSize(int pageSize) {
    this.pageSize = pageSize;
}

}

用工具类，方便快捷，抽空给你下一个

 public Pager pagedQuery(String hql, int currentPage, int pageSize, Map<String, Object> parmeMap) {
    if (pageSize == 0) {
        pageSize = 10;
    }
    int totalRows = getTotalRows(hql, parmeMap);
    int totalPages = 0;
    if (totalRows % pageSize == 0) {
        totalPages = totalRows / pageSize;
    } else {
        totalPages = totalRows / pageSize + 1;
    }
    int start = (currentPage - 1) * pageSize;
    if (totalPages < 1) {
        return new Pager();
    }
    Query query = getSession().createQuery(hql).setCacheable(true);
    setParameter(query, parmeMap);
    List<Object> list = query.setFirstResult(start).setMaxResults(pageSize).list();
    return new Pager(totalRows, currentPage, totalPages, list);
}
