一个Struts实现分页,增删改查,Tiles,国际化的DEMO

  public void setPage(String page) {
    this.page = page;
  }

  public String getPage() {
    return this.page;
  }

  public int doStartTag() throws JspException {
    if (this.page != null) {
      //从session里面取出来的是PageInfo对象的引用
      PageInfo pageBean = new PageInfo();
      pageBean = (PageInfo) (pageContext.getSession().getAttribute(this.
          page));
      //只要该PageInfo对象的总页数等于当前页数就不处理主体部分
      if (pageBean.getPageCountNumber() <= pageBean.getCurrentlyPage()) {
        return this.SKIP_BODY;
      }
      else {
        return this.EVAL_PAGE;//否则继续处理主体部分
      }
    }
    else {
      return this.SKIP_BODY;
