struts开发实践—分页的实现

本案主要功能是完成数据集的分页显示。示例代码如下：

 

1.PageInfo类：定义分页信息。

/******************program begin**************************/

package test;

 

import java.io.*;

 

public final class PaginationInfo

    implements Serializable {

  /**页大小描述每页有多少行*/

  private int pageSize = 20;

  /**是否有上一页*/

  private boolean hasPrevious;

  /**是否有下一页*/

  private boolean hasNext;

  /**总行数 */

  private int total;

  /**总页数 */

  private int totalPage;

  /**当前页码*/

  private int currentPageNumber=1;

  /**跳转动作：1:首页；2：前一页；3：后一页；4：末页*/

  private int jumpState;

  public void setPageSize(int pageSize) {

    this.pageSize = pageSize;

  }

 

  public int getPageSize() {

    return pageSize;

  }

 

  public void setHasPrevious(boolean hasPrevious) {

    this.hasPrevious = hasPrevious;

  }

 

  public boolean getHasPrevious() {

    return hasPrevious;

  }

 

  public void setPreviousPageNumber(int previousPageNumber) {

    this.previousPageNumber = previousPageNumber;

  }

 

  public int getPreviousPageNumber() {

    return previousPageNumber;

  }

 

  public void setHasNext(boolean hasNext) {

    this.hasNext = hasNext;

  }

 

  public boolean getHasNext() {

    return hasNext;

  }

 

  public void setNextPageNumber(int nextPageNumber) {

    this.nextPageNumber = nextPageNumber;

  }

 

  public int getNextPageNumber() {

    return nextPageNumber;

  }

 

  public void setTotal(int total) {

    this.total = total;

  }

 

  public int getTotal() {

    return total;

  }

 

  public void setTotalPage(int totalPage) {

    this.totalPage=totalPage;

  }

 

  public int getTotalPage() {

    return totalPage;

  }

 

  public void setCurrentPageNumber(int currentPageNumber) {

    this.currentPageNumber=currentPageNumber;

  }

 

  public int getCurrentPageNumber() {

    return currentPageNumber;

  }

  public void setJumpState(int jumpState){

    this.jumpState=jumpState;

  }

  public int getJumpState(){

    return jumpState;

  }

 

}
