遇到的问题----java jsp做数据分页翻页时遇到 java.lang.Integer cannot be cast to java.lang.String

 java代码:  

ActionContext context = ActionContext.getContext();
              int frepage = 1;
		int afterpage = 1;
	       int size = PageDocs.size();
		context.put("size", size);
		context.put("curpage", curpage);
		context.put("frepage", frepage);
		context.put("afterpage", afterpage);
	   return SUCCESS;

 jsp代码:

 

 <p>共<s:property value="size"/>条 当前页数<s:property value="curpage"/>  <a href="<%=basePath%>news/getNews?curpage=<s:property value="frepage"/>" target="_blank">上一页</a> <a href="<%=basePath%>news/getNews?curpage=<s:property value="afterpage"/>" target="_blank">下一页</a></p>
