show下我的分页类

	}

	}

	public String getStrlink() {

	}

	public void setStrlink(String strlink) {
		this.strlink = strlink;
	}

}

使用时,在action中建立该类的对象pr,并执行public void Show(boolean allRecord, boolean pageInfo, boolean pageNav,boolean jumpPage),将该对象放入ModelAndView,在页面使用${pr.strlink }就可以实现分页,如图


本人从事JAVA才1年,希望达到抛砖引玉的效果,大家把自己的工具拿出来show show,共同研究下,学习下
也建议版主弄一个工具包专题

这是webwork?? 放错地了。

输出都写死了，无法定制输出内容，无法定义样式，无法国际化，GetParamsFromCurrentUrl()……总之，很差。

<div id="product_page">
     ${pr.strlink }
</div>
样式可以定义,
国际化也可以使用哦,只是目前我这个项目没涉及到国际化,没改
这只是我个人使用的,有很多缺点,大家讨论下嘛,
多谢楼上的意见,希望大家多多提出意见,多多完善

在90%的项目里，国际化是假想需求.

怎么能把显示的数据放在类里面。太离谱了。
居然在方法里面拼html。。。丑陋。。丑陋到了极点。。

有啥好show的？写的这么烂

不加样式是比较难看
不过比较实用,至少我开发的时候可以一劳永逸.
楼上的靓仔,烂在哪里,说说,俺改改

很老的一个例子了！

不要总是批评人家写的程序不好，如果你们觉得自己写的水平高，也拿出来让大家学习学习啊。
