ADF Table分页

现象：

在开发群里看到不少人在找ADF的分页，虽然11gr2有自带分页，但之前的版本没有，在 一定程度上不是很方便，本文基于迭代器Iterator做了一下例子

源码：

1.managedBean部分

package view.backing;

import javax.faces.event.ActionEvent;

import model.vo.TablePageModelImpl;

import oracle.jbo.ViewObject;

import view.utils.ADFUtils;

public class BusinessBean {
    private int totalRows; //表中所有行数
    private int firstRecode; //每个记录页第一行
    private int currentPageNo = 1; //当前页数
    private int totalPage; //基表被分成的所有页数

    public BusinessBean() {
        //初始化 获取所有行数
        TablePageModelImpl am =
            (TablePageModelImpl)ADFUtils.getApplicationModuleForDataControl("TablePageModelDataControl");
        ViewObject vo = am.getAdT13UserOpTypeVO();
        totalRows = (int)vo.getEstimatedRowCount();
    }

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

    public int getTotalRows() {
        return totalRows;
    }

    public void setFirstRecode(int firstRecode) {
        this.firstRecode = firstRecode;
    }

    public int getFirstRecode() {
        firstRecode = (this.getCurrentPageNo() - 1) * 10 + 1;
        return firstRecode;
    }

    public void setCurrentPageNo(int currentPageNo) {
        this.currentPageNo = currentPageNo;
    }

    public int getCurrentPageNo() {
        return currentPageNo;
    }

    public void setTotalPage(int totalPage) {
        this.totalPage = totalPage;
    }

    public int getTotalPage() {
        totalPage =
                (this.totalRows % 10 == 0) ? (this.totalRows / 10) : ((this.totalRows /
                                                                       10) +
                                                                      1);
        return totalPage;
    }

    /**
     *首页
     * @param actionEvent
     */
    public void first(ActionEvent actionEvent) {
        System.out.println(totalRows);
        this.setCurrentPageNo(1);
        this.getFirstRecode();
    }

    /**
     *下一页
     * @param actionEvent
     */
    public void next(ActionEvent actionEvent) {
        if (this.getCurrentPageNo() < this.getTotalPage()) {
            this.setCurrentPageNo(this.getCurrentPageNo() + 1);
            this.getFirstRecode();
        }
    }

    /**
     *上一页
     * @param actionEvent
     */
    public void previous(ActionEvent actionEvent) {
        if (this.getCurrentPageNo() > 1) {
            this.setCurrentPageNo(this.getCurrentPageNo() - 1);
            this.getFirstRecode();
        }
    }

    /**
     *尾页
     * @param actionEvent
     */
    public void last(ActionEvent actionEvent) {
        this.setCurrentPageNo(this.getTotalPage());
        this.getFirstRecode();
    }

    /**
     *自选页数
     * @param actionEvent
     */
    public void go(ActionEvent actionEvent) {
        this.setCurrentPageNo(this.getCurrentPageNo());
        this.getFirstRecode();
    }
}

分页的方法还有很多，仅供参考
